AR to come to Google Maps
By rahmansunbeam,
I think most of us have had this experience, especially when you’re in a big city: you step off of public transit, take a peek at Google Maps to figure out which way you’re supposed to go… and then somehow proceed to walk two blocks in the wrong direction.
Maybe the little blue dot wasn’t actually in the right place yet. Maybe your phone’s compass was bugging out and facing the wrong way because you’re surrounded by 30-story buildings full of metal and other things that compasses hate.
From download Landsat images to NDVI (step by step)
By serdawe,
Dear all,
sorry if this topic exist here...
I have a few question:
I have downloaded three Landsat images (L1TP) because my study area is very big, there is overlapping between images. I would like to make NDVI for that area, and I am interested what the steps are:
Do I need to do atmospheric correction first, then I have use copy raster tool to eliminate black NoData part of the images?....after that how to merge (join) images but to avoid lines because of overlapping. After

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
