Hi, I’m fairly new to OSM. I am trying to learn how to effectively use Multipolygons and Relations. I have been having a hard time learning these two areas of OSM after reading and getting help from tutorials. I use JOSM with variety of plugins including the validation results. The question I have is when I create adjacent areas those areas come back with a “Area style way is not closed” then lists nodes. I cannot figure out how to fix this. I am trying to map a series of parking lot areas which are close together but with different restrictions, such as staff, motorcycle, police only, delivery.
After reading the wiki, I have tried to create a multipolygon followed by the adjacent areas which was unsuccessful. I also trial and error with relations in which I couldn’t get to comply with what I want.
I would like someones help in creating a step by step in JOSM on how to create a simple Area then attach an adjacent area onto the previous area. A brief use on how this can be used along side with Multipolygon and Relations.
I have searched and can find only help for a area within an area. Following this I would like to continue to be able to add areas adjacent areas, for an visual example like mapping parking_spaces.
