    Blank spaces in the map to a feature class in arcmap

    Maya007
    By Maya007,
    Hello, I have some basic doubts in Arc-Map. Please answer I want to convert the blank spaces within the map into another feature class. How could that be done? I have roads and forests in the map now. I want the remaining blank spaces to be like a feature class like polygons or even as raster. How is it possible? I tried by making a feature class (polygon) covering entire study area and then subtracted roads and forests from this using raster calculator. I then realized it do

    • GPS is an incredible piece of modern technology. Not only does it allow for locating objects precisely anywhere on the planet, but it also enables the turn-by-turn directions we take for granted these days — all without needing anything more than a radio receiver and some software to decode the signals constantly being sent down from space. [Chris] took that last bit bit as somewhat of a challenge and set off to write a software-defined GPS receiver from the ground up. As GPS started as a military technology, the level of precision needed for things like turn-by-turn navigation wasn’t always available to civilians. The “coarse” positioning is only capable of accuracy within a few hundred meters, so this legacy capability is the first thing that [Chris] tackles here. It is pretty fast, though, with the system able to resolve a location in 24 seconds from cold start and then displaying its information in a browser window. Everything in this build is done in Python as well, meaning that it’s a great starting point for investigating how GPS works and for building other projects from there. The other thing that makes this project accessible is that the only other hardware needed besides a computer that runs Python is an RTL-SDR dongle. These inexpensive TV dongles ushered in a software-defined radio revolution about a decade ago when it was found that they could receive a wide array of radio signals beyond just TV. source: Hackaday and  GitHub - chrisdoble/gps-receiver
