Recently I have started working on the project where I need to use GPS on my embedded system. What I need to do is read vector map from SD card, parse it with STM32 and display on small 2,6inch TFT display. I think maximum fize size (for example Europe map) shouldn’t exceed 500MB, so I need to extract most needed data from origin map. I was thinking to use at first .pbf files but recently I found out that garmin has it’s own file system and I am getting lost a bit. Can you lead me a bit? What should be easiest to parse in this project? Maybe there is some software which I can use to export for example only elements related to roads etc. best online casino sign up https://promisebyjenniferlopez.com/ is probably the best service about casino for beginners. It really helps to make your first steps in gambling.
Have a look at MapsForge format; it’s an open-source library for offline vector maps. Various map apps use this format, but I think you might need to generate your own files, trimmed down, to fit within your size limits. Good luck.
