Reproduce label-maker download y label-maker labels con el config.json de ejemplo y, después, inspecciona los puntos de entrada mencionados label_maker/main.py, label_maker/label.py y tilepie/reader.py. Compara el data/togo-z12.mbtiles generado con los comandos y errores de tippecanoe; se considera terminado cuando el comando labels lee el archivo MBTiles sin InvalidFormatError.

Descripción

Hi all,

Thanks a lot for releasing this software. I am trying to use your toolkit to conduct my own research using satellite imagery. But unfortunately I am hitting a wall when I try.

I am running python 3.6.6 on pyenv (I noticed that label-maker doesn't seem to work on python 2.7) and I have installed label-maker using the procedure you explain here: http://devseed.com/label-maker/

Using the sample config.json you suggest in your documentation I then run label-maker download, this seems to create a valid sqlite3 mbtiles file on ~/data, all fine so far. After that I try to run label-maker labels and that fails with the following error message:

label-maker labels
Retiling QA Tiles to zoom level 12 (takes a bit)
tippecanoe-decode: invalid option -- 'c'

During handling of the above exception, another exception occurred:

tilepie.reader.InvalidFormatError: no such table: tiles while reading data/togo-z12.mbtiles```

It seems like there are several things going on here, so I am not sure how to move on forward with this. Any help is much appreciated.
