Open Source GPS Software

Organic Maps is a free Android & iOS offline maps app for travelers, tourists, hikers, and cyclists. It uses crowd-sourced OpenStreetMap data and is developed with love by MapsWithMe (MapsMe) founders and our community. No ads, no tracking, no data collection, no crapware. Your donations and positive reviews motivate and inspire our small team! Organic Maps is the ultimate companion app for travelers, tourists, hikers, and cyclists. Detailed offline maps with places that don't exist on other maps, thanks to OpenStreetMap. Cycling routes, hiking trails, and walking paths. Contour lines, elevation profiles, peaks, and slopes. Turn-by-turn walking, cycling, and car navigation with voice guidance. Bookmarks export and import in KML/KMZ formats (GPX is planned). Organic Maps app is free from trackers and other bad stuff. Organic Maps is pure and organic, made with love.

This program will read from an active GPS device and save it to a TXT file. This can then be used to fake a GPS signal while your developing your own GPS based project. I think its easier to develop this way from the home/office over having to bring the laptop outside and test / develop. Completely free, source included for those who are only getting into development, just like myself Please leave a comment (Good or bad) if you're downloading and using it
