Hi, I want to have a map on my garmin where I can only see Drinking water symbols (and the basic map with roads, buildings and so on…). So just a “drinking water map”. I have a Garmin Edge 705 (doesn’t work with garmin poi loader).
My idea is to modify a map and delete all symbols except for drinking water. What do I need to do this and how?
Thank you! That helped me A LOT!
The only problem now is zoom level: Where can I define at what zoom level the pois are visible? I tried to edit the style files of the program and set the resolution from 14 to 0, now I see the symbols when it shows 300m scale on my Garmin instead of 200m. But I need like 1-2km at least, how do I do that?
Also, some symbols are shown and others are not. I just see the poi name without the symbol… Picnic and Drinking Water Symbols work, others like shelter, hotel or food don’t…?
I assume you have found and edit the points file in the programm directory at Program Files (x86)\IMGfromGPX\Resources\styles\default\ ? The line for drinking water pois are defined by this line
amenity=drinking_water [0x5000 resolution 14 default_name ‘Water’]
Don’t change those 14 into 0 that does not make any sense; resolution 14 means that it is shown at every zoom level, from the lowest to the highest. So better leave that this way. It must be a setting in your Garmin to see it at lower zoom levels but Im not familiar with your Edge.
Yes, I changed the 14 into 0 in the points file.
My Garmin is pretty old and doesn’t have that many options, it only has a “details” option where you can choose between “minimal”, “normal”, and up to “maximum”. At maximum, the POIs are shown at higher zoom levels but still not what I want.
Is it all just in the settings of the device that changes at what zoom levels I can see the Symbols or is there a way to modify the map to see the symbols at higher zoom levels?
To see it further out you probably need to use another Garmin Feature code and a custom icon using mkgmap. What I’ve done for this sort of thing is a single transparent overlay layer, but it’s a while since I did this (perhaps 10 years for bus stops), so I may not have any examples to hand.
