Hello,
I would like to choose shown items on my OSM maps. For example "Site camps" or "Drinking Water Points".
For the moment it's possible but by choosing a group of similar items ("Water Points" + "Springs" + "Other" (have a look to the attached file).
Do you know how can I do this?
Regards.
I don't know which Theme you are currently using, but the only solution is to customize this Theme to meet your requirements.
Technically speaking, this consists in modifying the XML file that drive your theme.
It is feasible.... but quite complex, and needs to understand how Mapsforge Render Themes are working.
You have first to modify the selection menu, to create the categories you want in place of the existing ones (easy part of the work), but afterwards to go inside the system of rules and their conditions to base the display on your new conditions.
Depending on how the theme is written, and on the modification you want to implement, this can be quite simple.... but generally VERY VERY complex.
As a matter of example, I have recently modified for my personal usage the Openandromaps Theme Elevate/Elements to separate the ski tracks display from other sports. It was easy to do, because
1) the drawing of ski tracks were clearly identified in the XML code,
2) and that I had "only" to add a new option, and condition this drawing (of ski tracks) to my new condition rather than to the global "sport" condition,
But I would say we were there in a very simple case...
Hello LaurentG,
Thank you for explanations.
Like you, I'm using too the Openandromaps Theme Elevate/Elements.
I don't want to spend to much time to write a new XML file. I'm a newbie in this.
I'm going to use the theme as is.
Regards.
