On a tangent, but any suggestions for a tool to stitch up drone aerial imagery and use it as a map?

Preferably on the phone/tablet.

Sounds like the perfect tool for a spy/hacker/csi TV show.

Interesting.

Take quite some time to install. And some images are great like `felicette -l "New York" Some totally blank (real time and dark) felicette -l "Hong Kong" Some not sure as a bit random like those of Three Gorges Dam using ``` felicette -c 109.5568 31.0390 felicette -c 111.003761 30.823748 felicette -c 110.25 30.95 ``` One has coloured and the other not sure.

I guess this is part of being satellite images?

That's not high-resolution.

I give it a coordinate and it give me a picture of the French and UK sea towns. That is quite a low resolution I guess.

Looks like a great tool, but its dependencies are sufficiently complex to warrant a Dockerfile. This way it would be very clear what the dependencies are independent of how the host system is configured.

I just pushed a Docker build here: https://hub.docker.com/r/milhouse1337/felicette

You can use it like this:

  docker run -it -v "$PWD"/felicette-data:/root/felicette-data milhouse1337/felicette felicette -l "Montreal"

That's a very cool project to play with! Thank you @plant99 for this.

Felicette is a dead-simple CLI tool which searches, downloads, generates, and visualizes satellite imagery in the form of RGB jpegs, taking inputs in the form of location's name or coordinates. It also has options to visualize CIR vegetation data.

Seems nice but sends you to dependency hell when you try to install on Ubuntu. On 18.04, it can't find the correct openvc On 19.04, same things On 20.04, the repo doesn't include config for 20.04 Would love to try it, but ...

You can try the Docker build I just made if you want: https://news.ycombinator.com/item?id=23951167

I'm used to writing latitude first when writing coordinates so I couldn't get the tool to find any images for a while. Other than that neat tool

Wow, that just makes it a lot simpler for people to test/use. Could you please share your GitHub username, so I can attribute with a link to the docker image in the README?

Thanks for the feedback, I agree with you on this. I'll add this to the to-do list.

[pipx]( https://pipxproject.github.io/pipx/ ) is a nice way to download python CLI apps in a separate contained virtual env. But I couldn't install your app with it: https://pastebin.com/syUPRDCp

Oh from the logs it looks like `numpy` wasn't installed. Please install GDAL=={ogrinfo --version}, and numpy before installing felicette, and that'd most probably solve it.

Um, don't know of a tool to process aerial imagery using phone/tablet.

But I'm sure you're aware of https://qgis.org/en/site/. Some of my friends used this to analyze vegetation using drone imagery.
