Contour lines was not display.Is it because the themes of Roam are not compatible V2？

Hi @mushroom11s! the device theme in my repo is universal but tailored for BOLTv1. There might be not enough configured to display contour lines on a ROAMv2.

You might read here and try the theme from @masc4ii, this is tailored for BOLTv2 and contour lines :-) Just to make sure: did you generate maps including contour lines? This is a prerequesite.

Yes. I have included Contour line on the map. The generation time is too long!!! 😭😭 I am generating a map for China, and this basic data is too large (approximately 450G). I spent 2 days generating it.

:-D Wow! Yes contour lines take some additional times. What you could do actually is to only generate certain XY-coordinates. That's what I sometimes do (before holiday etc.) to have new maps for a specific region.

Sorry I forgot to link to the theme I mentioned, here it is: https://github.com/treee111/wahooDeviceThemes/tree/link-themes/VTM/masc4ii

Thank！May be can provide the provincial level generation. I'm sorry, I don't have much knowledge of GIS and can't provide some help in implementing this feature. I can only wait for you to do it well.🙏🏻😐

Have you been able to display contour lines with the theme I mentioned?

Think of implementing a provincial possibility, that might not be doable on a geofabrik way for China:

• http://download.geofabrik.de/asia/china.html has no subregions
• http://download.geofabrik.de/europe/germany.html in comparison has subregions

🙏🏻😸 Yes,is worked. But contour line value is not displayed on line.I don't know how to configure it.

If I want use the command line to generate some areas like img.What "- xy" value do I need to enter?

[treee111]

perfect that contour lines are displayed! I don't think the height meters are included in the map and thus it's not possible to display them. Would clutter the display also too much maybe

-xy is documented here. Just follow the link given there and zoom into your area with zoom level = 8 z=0 You can also supply more that one xy-coordinate to the tool (i.e. your area!)

should be that, right?

Thanks very much! This answer is very helpful. Thank you for your patient response. I immediately understood when I saw this picture,I used to think that xy was just a point, not an area😅

you are welcome! Maybe I should add a little more information about xy in the docs 👍
