Objections

  • Hard to install due to GDAL and dependency issues on Ubuntu

    From 3 comments
    • 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…

    • [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:…

    • 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…

  • Imagery resolution too low (Landsat 30m)

    • 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.

  • Some images blank or odd for certain locations

    From 1 comment
    • 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…

  • Data source and licensing undocumented in README

    From 3 comments
    • Where the data are coming from? Can't find a word about it in README.
      ComodoHacker on HN
    • Neat project! The example photos in Drive are a bit wonky on mobile and only one of the files is accessible. Consider adding a few example photos in the readme. What’s the…

    • Yeah amazing they’ve left out the key info like source of images. Does this API need a token?

  • Support Sentinel 2 imagery

    From 1 comment
    • For a little more effort you could "interleave" the Sentinel 2 images as well, which are of a similar resolution and also have a simple access API.

  • Higher-resolution sources such as NAIP

  • Allow farbfeld output and custom band assignment

    From 1 comment
    • Here are some possibilities to add: - Allow farbfeld output (to stdout) - Allow specifying your own assignment of bands - Allow to skip the colour adjustment if you want to do…

    • is it live? Like can a get a pic of a place made at day light in the last 24 hours?

Alternatives named

  • aerialbot, a tile-based satellite image tool

    • This is neat! I’ve built something similar, although my tool can pull its data from any service that supports tile indexing via the Web Mercator Transform (e.g. Google Maps, OSM,…

    • Looking at the code, it appears to be a nice front end to sat-search https://github.com/sat-utils/sat-search

    • 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.
      DenisM on HN
    • https://www.opendronemap.org/ Works quite well. Input images must have geo data in the exif metadata like longitude, latitude, FOV, camera pitch (most drones e.g. Autel and DJI…
