Tantangan MapRoulette untuk menyelesaikan bangunan yang berpotongan

Syed_N · July 20, 2023, 10:36am

Halo,

Saya Syed dari TomTom. Saya mohon maaf sebelumnya jika Anda menemukan kesalahan dalam bahasa saya, mengingat saya menggunakan penerjemah online.

Setelah menerima permintaan untuk tumpang tindih contoh bangunan, kami mengidentifikasi 514 skenario seperti itu di Jakarta dan sekitarnya dan kemudian membuat tantangan berikut ini:

https://maproulette.org/browse/challenges/40228

Jika Anda tertarik, Anda dapat menyelesaikan tugas ini dengan menggunakan sumber-sumber yang tersedia, pengetahuan lokal, dan instruksi yang disediakan di MapRoulette. Jika Anda ingin memperbaiki skenario tumpang tindih yang berpotensi salah, Anda dapat mengakses tantangan sebelumnya yang menyoroti bangunan dan jalan raya yang bersinggungan:

https://maproulette.org/browse/challenges/39928

Seperti biasa, saya meminta Anda untuk berbagi umpan balik yang berharga mengenai tantangan ini atau topik lainnya.

Anda dapat menemukan informasi di GitHub mengenai kegiatan perbaikan data kami di Indonesia:

# Project description ## Goal Improving the map quality in Indonesia by sharin…g tasks that can help fix data errors and/or add certain kinds of features. ## How to participate Anyone is welcome to contribute to this project by participating in our MapRoulette challenges. Here is the [extended documentation](https://learn.maproulette.org/documentation) for using MR. Note that sometimes additional instructions are provided within the challenges. We also strongly encourage you to follow [good practices](https://wiki.openstreetmap.org/wiki/Good_practice#Align_aerial_imagery_before_tracing), [editing standards](https://wiki.openstreetmap.org/wiki/Editing_Standards_and_Conventions), and [tagging conventions for Indonesia](https://wiki.openstreetmap.org/wiki/Indonesia#Tagging_conventions). Here is the current [set of challenges](https://maproulette.org/browse/projects/48590). ## Active Challenges ### Fix Intersecting Buildings Identify and fix, if needed, situations where a building intersects with another building at the same layer. - [Indonesia - Fix Intersecting Buildings](https://maproulette.org/browse/challenges/40228) ### Fix Building and Highway Intersections Identify and fix, if needed, cases where a way intersects with a building. - [Indonesia - Fix Building and Highway Intersections](https://maproulette.org/browse/challenges/39928) ### Fix Inconsistent Highway Intersections Identify and fix cases where highways intersect without a common node. - [Indonesia - Fix inconsistent highway intersections](https://maproulette.org/browse/challenges/39413) ### Fix Inconsistent Bridge and Tunnel Tagging Identify and fix cases where the bridge or tunnel has an incorrect tag. - [Indonesia - Fix inconsistent bridge and tunnel tagging](https://maproulette.org/browse/challenges/38701) ### Connect Isolated Highways Ways with tag highway=* must be connected to the rest of the road network to ensure its continuity, e.g. for route planning. When such a way is not connected to another way with tag highway=*, an error is logged. - [Indonesia - Connect Isolated Highways](https://maproulette.org/browse/challenges/38359) </details> ## Inactive Challenges <details> <summary>Click to expand.</summary> ### Connect Isolated Highways - [Not connected highway](https://maproulette.org/browse/challenges/27824) ### Add Surface to Highway - [Indonesia - Add Surface to Highway](https://maproulette.org/browse/challenges/38235) - [Indonesia - Add Surface to Highway - Jan 2023](https://maproulette.org/browse/challenges/37472) Identify and add missing surface tags on a road network. ### Other Quality Check Challenges - [Invalid Lane Tag](https://maproulette.org/browse/challenges/27828) The tag lanes=* on ways with tag highway=* indicates the amount of lanes on the road at hand. The value for the lanes tag should be only one of the following numbers: 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10. Any other value is incorrect and should be fixed. - [Tag area=yes on object without feature type](https://maproulette.org/browse/challenges/27826) The area=yes tag is required for some closed ways when used to define a polygon. For closed ways with other tags, there is an assumption that the way defines an area. In some circumstances, a closed way may define both a closed polyline and an area. When tag area=yes is used, it is expected that one of the necessary accompanying tags is also found. - [Impossible angle in a highway](https://maproulette.org/browse/challenges/27825) In general, roads intended for vehicles should be built to maintain proper angles which ensure maneuvers and fluent traffic. Extreme, too sharp angles applied to a way may indicate errors in the road geometry. - [Invalid Turn Restriction](https://maproulette.org/browse/challenges/27829) This check identifies invalid turn restrictions. Invalid turn restrictions occur in a variety of ways, from invalid members to edge geometry issues to not being routable to wrong topology. Relations, ways and nodes in relations as well as turn restrictions are checked. A relation needs to have exactly one way with role 'from' and exactly one way with role 'to'. These ways should be linked together by at least one way with role 'via' OR with exactly one node with role 'via' (no more and no less). - [Invalid Mini-Roundabout](https://maproulette.org/browse/challenges/27833) Mini-roundabouts are a special kind of roundabout with the same rules as other roundabouts, but present as painted circles rather than physical circles. There might also be a low, fully traversable dome or island that vehicles can drive across. Road traffic flows in one direction around a point in the middle, and the traffic in the roundabout has right-of-way. A mini-roundabout is recorded using the tag highway=mini_roundabout. - [Polygon has self-intersection](https://maproulette.org/browse/challenges/27827) The necessary edits will be made to fix cases where the tag on a way indicates that the object is a polygon feature, but the way does not meet the definition of a closed way because it is self-intersecting, or ways in a relation with the same role form a self-intersecting polygon - [This multipolygon is a simple polygon](https://maproulette.org/browse/challenges/27822) Simple areas are mapped in OSM by creating a closed way and tagging it as an area object rather than a line. Relations of the type multipolygon are used to represent complex areas with holes inside or consisting of multiple disjoint areas. A multipolygon relation can have any number of ways in the role outer (the outline) and any number of ways in the role inner (the holes), and these must form valid rings to build a multipolygon. When a relation of the type multipolygon consists of only one member, which is a simple area, an error is logged. - [Spiky buildings](https://maproulette.org/browse/challenges/27823) Buildings with extremely sharp angles will be identified and corrected if needed. - [Polygon is not closed](https://maproulette.org/browse/challenges/27830) Features intended to be a polygon should be correctly tagged. When the tag indicates that the object should be a polygon, but the geometry is built out of a NON-closed way, an error is logged. </details> ## Edits based on Map Feedback <details> We will make improvements to OSM based on user feedback submitted for the TomTom map after comparing and ensuring that it is also valid for OSM. Here is a list of the types of edits that could be made, provided they do not conflict with others’ edits and a local source is available: - Highways - Adding highways - Realigning highways - Adding or adjusting bridges, tunnels, layers, or relations - Updating lanes - Updating traffic signs - Addresses - Adding or correcting addresses - Updating the position of address nodes, usually when an object has multiple addresses - Adding or correcting names of ways - POIs (Points of Interest) - Adding POIs - Correcting POI locations - Adding or correcting POI information - Resolving POI-land use discrepancies - Handling POI closures - Land Use - Adding land use - Modifying existing land use extent - Adjusting building shape - Buildings - Adding buildings - Updating building type - Adjusting building shape - Water - Adding or realigning rivers, streams, and lakes. </details> ## Geographical scope Data improvements will be made across the whole country. ## Announcements - Notified about the Indonesia - Fix Intersecting Buildings challenge on 20-Jul-2023 in the [Indonesia community forum]() - Notified about the Indonesia - Fix Building and Highway Intersections challenge on 30-Jun-2023 in the [Indonesia community forum](https://community.openstreetmap.org/t/tantangan-untuk-memperbaiki-jalan-raya-yang-bersinggungan-dengan-bangunan/100655) - Notified about the Inconsistent Highway Intersections challenge on 25-May-2023 in the [Indonesia community forum](https://community.openstreetmap.org/t/tantangan-maproulette-untuk-memperbaiki-persimpangan-jalan-raya-yang-tidak-konsisten/99457) - on 21-April-2023 in [Indonesia OSM Community](https://community.openstreetmap.org/t/tantangan-maproulette-baru-dan-aktivitas-umpan-balik-peta-tomtom/98245) - on 28-March-2023 in [Indonesia OSM Community](https://community.openstreetmap.org/t/tantangan-maproulette-jalan-raya-terisolasi/97434) - on 2-March-2023 in [Indonesia user forum](https://forum.openstreetmap.org/viewtopic.php?pid=874882#p874882) and [Indonesia OSM Community](https://community.openstreetmap.org/t/tantangan-maproulette-permukaan-yang-hilang/8408/3?u=syed_n) - on 31-Jan-2023 in [Indonesia user forum](https://forum.openstreetmap.org/viewtopic.php?pid=874619#p874619) and [Indonesia OSM Community](https://community.openstreetmap.org/t/tantangan-maproulette-permukaan-yang-hilang/8408?u=syed_n) - on 20-Jun-2022 in [Indonesia user forum](https://forum.openstreetmap.org/viewtopic.php?id=75816) and [Komunitas OpenStreetMap Indonesia](https://www.facebook.com/groups/osm.id/permalink/5280354508688516/) ## TomTom organised editing We will follow the [Organised Editing Guidelines](https://wiki.osmfoundation.org/wiki/Organised_Editing_Guidelines) for this project. TomTom will not make any edits until two weeks after the project announcement. Here is our [Organised Editing page](https://wiki.openstreetmap.org/wiki/Organised_Editing/Activities/TomTom), including a list of our editors. ### How to find TomTom's edits All edits made by our team have the hashtag #tt or #tomtom. ## Sources for editing - Maxar - Esri - Bing ## How to reach out If you have remarks about a specific edit of ours, please drop a comment in the changeset, and we will do our best to respond thoughtfully. Or, you can also: - send a message to the project lead [Syed](https://www.openstreetmap.org/user/Syed_N) - join the conversation in the [Indonesia community forum]() - email [osm@tomtom.com](mailto:osm@tomtom.com) for general questions about TomTom's activities.

Selamat memetakan.

Hello,

I am Syed from TomTom. After a community member requested for leads that point to overlapping buildings, we identified 514 such scenarios in and around Jakarta and created the following challenge:

https://maproulette.org/browse/challenges/40228

If interested, you can solve these tasks using available sources, local knowledge, and the instructions provided in MapRoulette. If you would like to work on more scenarios involving intersecting ways, you can access an earlier challenge that highlighted intersecting buildings and highways:

https://maproulette.org/browse/challenges/39928

As always, I request you to share your valuable feedback concerning this challenge or any other topics.

# Project description ## Goal Improving the map quality in Indonesia by sharin…g tasks that can help fix data errors and/or add certain kinds of features. ## How to participate Anyone is welcome to contribute to this project by participating in our MapRoulette challenges. Here is the [extended documentation](https://learn.maproulette.org/documentation) for using MR. Note that sometimes additional instructions are provided within the challenges. We also strongly encourage you to follow [good practices](https://wiki.openstreetmap.org/wiki/Good_practice#Align_aerial_imagery_before_tracing), [editing standards](https://wiki.openstreetmap.org/wiki/Editing_Standards_and_Conventions), and [tagging conventions for Indonesia](https://wiki.openstreetmap.org/wiki/Indonesia#Tagging_conventions). Here is the current [set of challenges](https://maproulette.org/browse/projects/48590). ## Active Challenges ### Fix Intersecting Buildings Identify and fix, if needed, situations where a building intersects with another building at the same layer. - [Indonesia - Fix Intersecting Buildings](https://maproulette.org/browse/challenges/40228) ### Fix Building and Highway Intersections Identify and fix, if needed, cases where a way intersects with a building. - [Indonesia - Fix Building and Highway Intersections](https://maproulette.org/browse/challenges/39928) ### Fix Inconsistent Highway Intersections Identify and fix cases where highways intersect without a common node. - [Indonesia - Fix inconsistent highway intersections](https://maproulette.org/browse/challenges/39413) ### Fix Inconsistent Bridge and Tunnel Tagging Identify and fix cases where the bridge or tunnel has an incorrect tag. - [Indonesia - Fix inconsistent bridge and tunnel tagging](https://maproulette.org/browse/challenges/38701) ### Connect Isolated Highways Ways with tag highway=* must be connected to the rest of the road network to ensure its continuity, e.g. for route planning. When such a way is not connected to another way with tag highway=*, an error is logged. - [Indonesia - Connect Isolated Highways](https://maproulette.org/browse/challenges/38359) </details> ## Inactive Challenges <details> <summary>Click to expand.</summary> ### Connect Isolated Highways - [Not connected highway](https://maproulette.org/browse/challenges/27824) ### Add Surface to Highway - [Indonesia - Add Surface to Highway](https://maproulette.org/browse/challenges/38235) - [Indonesia - Add Surface to Highway - Jan 2023](https://maproulette.org/browse/challenges/37472) Identify and add missing surface tags on a road network. ### Other Quality Check Challenges - [Invalid Lane Tag](https://maproulette.org/browse/challenges/27828) The tag lanes=* on ways with tag highway=* indicates the amount of lanes on the road at hand. The value for the lanes tag should be only one of the following numbers: 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10. Any other value is incorrect and should be fixed. - [Tag area=yes on object without feature type](https://maproulette.org/browse/challenges/27826) The area=yes tag is required for some closed ways when used to define a polygon. For closed ways with other tags, there is an assumption that the way defines an area. In some circumstances, a closed way may define both a closed polyline and an area. When tag area=yes is used, it is expected that one of the necessary accompanying tags is also found. - [Impossible angle in a highway](https://maproulette.org/browse/challenges/27825) In general, roads intended for vehicles should be built to maintain proper angles which ensure maneuvers and fluent traffic. Extreme, too sharp angles applied to a way may indicate errors in the road geometry. - [Invalid Turn Restriction](https://maproulette.org/browse/challenges/27829) This check identifies invalid turn restrictions. Invalid turn restrictions occur in a variety of ways, from invalid members to edge geometry issues to not being routable to wrong topology. Relations, ways and nodes in relations as well as turn restrictions are checked. A relation needs to have exactly one way with role 'from' and exactly one way with role 'to'. These ways should be linked together by at least one way with role 'via' OR with exactly one node with role 'via' (no more and no less). - [Invalid Mini-Roundabout](https://maproulette.org/browse/challenges/27833) Mini-roundabouts are a special kind of roundabout with the same rules as other roundabouts, but present as painted circles rather than physical circles. There might also be a low, fully traversable dome or island that vehicles can drive across. Road traffic flows in one direction around a point in the middle, and the traffic in the roundabout has right-of-way. A mini-roundabout is recorded using the tag highway=mini_roundabout. - [Polygon has self-intersection](https://maproulette.org/browse/challenges/27827) The necessary edits will be made to fix cases where the tag on a way indicates that the object is a polygon feature, but the way does not meet the definition of a closed way because it is self-intersecting, or ways in a relation with the same role form a self-intersecting polygon - [This multipolygon is a simple polygon](https://maproulette.org/browse/challenges/27822) Simple areas are mapped in OSM by creating a closed way and tagging it as an area object rather than a line. Relations of the type multipolygon are used to represent complex areas with holes inside or consisting of multiple disjoint areas. A multipolygon relation can have any number of ways in the role outer (the outline) and any number of ways in the role inner (the holes), and these must form valid rings to build a multipolygon. When a relation of the type multipolygon consists of only one member, which is a simple area, an error is logged. - [Spiky buildings](https://maproulette.org/browse/challenges/27823) Buildings with extremely sharp angles will be identified and corrected if needed. - [Polygon is not closed](https://maproulette.org/browse/challenges/27830) Features intended to be a polygon should be correctly tagged.

Extreme, too sharp angles applied to a way may indicate errors in the road geometry. - [Invalid Turn Restriction](https://maproulette.org/browse/challenges/27829) This check identifies invalid turn restrictions. Invalid turn restrictions occur in a variety of ways, from invalid members to edge geometry issues to not being routable to wrong topology. Relations, ways and nodes in relations as well as turn restrictions are checked. A relation needs to have exactly one way with role 'from' and exactly one way with role 'to'. These ways should be linked together by at least one way with role 'via' OR with exactly one node with role 'via' (no more and no less). - [Invalid Mini-Roundabout](https://maproulette.org/browse/challenges/27833) Mini-roundabouts are a special kind of roundabout with the same rules as other roundabouts, but present as painted circles rather than physical circles. There might also be a low, fully traversable dome or island that vehicles can drive across. Road traffic flows in one direction around a point in the middle, and the traffic in the roundabout has right-of-way. A mini-roundabout is recorded using the tag highway=mini_roundabout. - [Polygon has self-intersection](https://maproulette.org/browse/challenges/27827) The necessary edits will be made to fix cases where the tag on a way indicates that the object is a polygon feature, but the way does not meet the definition of a closed way because it is self-intersecting, or ways in a relation with the same role form a self-intersecting polygon - [This multipolygon is a simple polygon](https://maproulette.org/browse/challenges/27822) Simple areas are mapped in OSM by creating a closed way and tagging it as an area object rather than a line. Relations of the type multipolygon are used to represent complex areas with holes inside or consisting of multiple disjoint areas. A multipolygon relation can have any number of ways in the role outer (the outline) and any number of ways in the role inner (the holes), and these must form valid rings to build a multipolygon. When a relation of the type multipolygon consists of only one member, which is a simple area, an error is logged. - [Spiky buildings](https://maproulette.org/browse/challenges/27823) Buildings with extremely sharp angles will be identified and corrected if needed. - [Polygon is not closed](https://maproulette.org/browse/challenges/27830) Features intended to be a polygon should be correctly tagged. When the tag indicates that the object should be a polygon, but the geometry is built out of a NON-closed way, an error is logged. </details> ## Edits based on Map Feedback <details> We will make improvements to OSM based on user feedback submitted for the TomTom map after comparing and ensuring that it is also valid for OSM. Here is a list of the types of edits that could be made, provided they do not conflict with others’ edits and a local source is available: - Highways - Adding highways - Realigning highways - Adding or adjusting bridges, tunnels, layers, or relations - Updating lanes - Updating traffic signs - Addresses - Adding or correcting addresses - Updating the position of address nodes, usually when an object has multiple addresses - Adding or correcting names of ways - POIs (Points of Interest) - Adding POIs - Correcting POI locations - Adding or correcting POI information - Resolving POI-land use discrepancies - Handling POI closures - Land Use - Adding land use - Modifying existing land use extent - Adjusting building shape - Buildings - Adding buildings - Updating building type - Adjusting building shape - Water - Adding or realigning rivers, streams, and lakes. </details> ## Geographical scope Data improvements will be made across the whole country. ## Announcements - Notified about refilling the 'Indonesia - Fix Building and Highway Intersections' challenges on 05-September-2023 in the [Indonesia community forum]() - Notified about refilling the 'Indonesia - Fix Intersecting Buildings' and 'Indonesia - Fix Building and Highway Intersections' challenges on 20-Jul-2023 in the [Indonesia community forum](https://community.openstreetmap.org/t/tantangan-maproulette-untuk-menyelesaikan-bangunan-yang-berpotongan/101447/2) - Notified about the Indonesia - Fix Intersecting Buildings challenge on 20-Jul-2023 in the [Indonesia community forum](https://community.openstreetmap.org/t/tantangan-maproulette-untuk-menyelesaikan-bangunan-yang-berpotongan/101447) - Notified about the Indonesia - Fix Building and Highway Intersections challenge on 30-Jun-2023 in the [Indonesia community forum](https://community.openstreetmap.org/t/tantangan-untuk-memperbaiki-jalan-raya-yang-bersinggungan-dengan-bangunan/100655) - Notified about the Inconsistent Highway Intersections challenge on 25-May-2023 in the [Indonesia community forum](https://community.openstreetmap.org/t/tantangan-maproulette-untuk-memperbaiki-persimpangan-jalan-raya-yang-tidak-konsisten/99457) - on 21-April-2023 in [Indonesia OSM Community](https://community.openstreetmap.org/t/tantangan-maproulette-baru-dan-aktivitas-umpan-balik-peta-tomtom/98245) - on 28-March-2023 in [Indonesia OSM Community](https://community.openstreetmap.org/t/tantangan-maproulette-jalan-raya-terisolasi/97434) - on 2-March-2023 in [Indonesia user forum](https://forum.openstreetmap.org/viewtopic.php?pid=874882#p874882) and [Indonesia OSM Community](https://community.openstreetmap.org/t/tantangan-maproulette-permukaan-yang-hilang/8408/3?u=syed_n) - on 31-Jan-2023 in [Indonesia user forum](https://forum.openstreetmap.org/viewtopic.php?pid=874619#p874619) and [Indonesia OSM Community](https://community.openstreetmap.org/t/tantangan-maproulette-permukaan-yang-hilang/8408?u=syed_n) - on 20-Jun-2022 in [Indonesia user forum](https://forum.openstreetmap.org/viewtopic.php?id=75816) and [Komunitas OpenStreetMap Indonesia](https://www.facebook.com/groups/osm.id/permalink/5280354508688516/) ## TomTom organised editing We will follow the [Organised Editing Guidelines](https://wiki.osmfoundation.org/wiki/Organised_Editing_Guidelines) for this project. TomTom will not make any edits until two weeks after the project announcement. Here is our [Organised Editing page](https://wiki.openstreetmap.org/wiki/Organised_Editing/Activities/TomTom), including a list of our editors. ### How to find TomTom's edits All edits made by our team have the hashtag #tt or #tomtom. ## Sources for editing - Maxar - Esri - Bing ## How to reach out If you have remarks about a specific edit of ours, please drop a comment in the changeset, and we will do our best to respond thoughtfully. Or, you can also: - send a message to the project lead [Syed](https://www.openstreetmap.org/user/Syed_N) - join the conversation in the [Indonesia community forum](https://community.openstreetmap.org/t/tantangan-maproulette-untuk-menyelesaikan-bangunan-yang-berpotongan/101447) - email [osm@tomtom.com](mailto:osm@tomtom.com) for general questions about TomTom's activities.

Happy mapping.
