I’d like to use opentopomap on my garmin device for my mountain trips.
The thing is, the quality of the maps on opentopomap.org is very good, but when I download the map from http://garmin.opentopomap.org, the map is very very basic, lacking even contour lines.
Let’s take the Matterhorn for example. Here’s what it looks like on opentopomap.org:
And what it looks like downloaded from garmin.opentopomap.org, opened in Basecamp application:
My 2 questions:
How to get contour lines on garmin map? On garmin.opentopomap.org it says “Contour lines as optional layer”, but I don’t know how to enable it.
Is it possible to get better quality for garmin (similar to the real opentopomap)?
I know that it has to fit limited devices memory, but for my trips I prefer to have small area in good quality, than big area in bad quality.
The maps for garmin are so simple it doesn’t even make sense to buy device with color screen…
I did download contour lines + opentopomap turkey. they both shown on basecamp separately.
1- how to see two maps together?
2- I tried gmapstool to combine OpenTopoMap & contours turkey but failed !
You don’t need to combine them, the contour layer is transparent and has higher vertical priority than plain map layer, so just put both maps on the device and enable them.
I create a map for my area using OSM .img I get from bbbike and I combine it with contour lines every 10 meters. I generated the contour lines a while ago, but I think I got them from viewfinderpanoramas.org (.hgt), and convert them to .img. Then I join them (using gmaptool) with the .img from bbbike. It is possible to get contour lines from bbikes too but they are every 40 m. (https://libreriacrisol.blogspot.com/p/mapa-de-aventura-en-chihuahua-para-gps.html)
Did not know about this map! Nice looking one, but it really seems there are a lot of data cut out of from how it looks like on the web versus what gets put into the img file.
First things I noticed and that are a major downside against using this map is that intermittent waterways and even some non-intermittent are not rendered - like ditches. Also addresses and isolated dwellings not there.
