Help with Landsat ARD Metadata?
By SandhillSasquatch,
So i've been using landsat data for some of the research that I do, and the application I use if ENVI. I haven't had too much difficulty, it has a built in feature to open georeferenced files with metadata just by opening the MTL.txt that the landsat data generates when you unzip it.
However, the new Analysis Ready Data (ARD) that I really want to try and use, generates a .xml file for the metadata and ENVI doesn't know what to do with it. I've tried converting to a .txt and changing the na
Reclassify thematic dataset
By Maya007,
I read in some instructions that it is safer to reclassify with codes like value in the reclass dialogue box instead of fields like ex: Geology . Is it because there are more possibility for errors in this than in the values. I find it more easier to reclassify if it is based on descriptions like geology.
Are there some other reasons that reclassification works better with values than with fields like descriptions?
Thanks,
Maya.

Delete batch point
By Maya007,
Hello again,
I am trying to delineate watershed using ArcHydro. I wrongly marked the outlet and generated a batch point. i would like to delete this and start with new one. How could this be done
Thanks,

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
