OpenStreetMap4Primer2 – The Portable and Smart Map Reader!
In present days, it’s definitely not a big deal to connect a GPS receiver to a microcontroller. Normally, the GPS receivers send data and pack into NMEA format, as a serial stream over a serial port!
The only problem is what should we do with the data? For tracking purposes, it’s just only enough to save the data stream to a nonvolatile memory. If you want to visualize the GPS data on your device, such as show your actual position on a map, and then you’re facing two main problems here:
-
Firstly, you have to deal with a big amount of map data.
-
Secondly, the map data underlies restrictive copyright licenses!
Thanks to the incredible OpenStreetMap4Primer2, you can easily overcome the above two problems.
For your information, the OSM4Primer2 is an awesome device, as it allows the map data to be stored and recovered from the micro-SD card.
In this case, you only have to download the desired map data from OSM project and save the map to the micro-SD card. Furthermore, the OSM4Primer2 can be used to extract the actual geographical position out of the NMEA data stream. After that, it displays the correct position on the map instantly!
product is transparent, so that we can see elements in it, but I rather feel less practical, because there is just one element protruding from the casing. But perhaps if viewed from the function will be very useful
