Gulf of Mexico bathymetry

Looks like 40 feet x 40 feet cells which is in the 10 meter range, which would be good for zoom 15.

Transcode data

Note that I'm transcoding these two images with the Docker image locally since they're pretty small.

docker run \
  -e DATABASE_URL=redacted \
  -e AWS_ACCESS_KEY_ID=redacted \
  -e AWS_SECRET_ACCESS_KEY=redacted \

These both failed during the rio shapes call with the following error:

CPLE_AppDefinedError: Full reprojection failed, but partial is possible if you define OGR_ENABLE_PARTIAL_REPROJECTION configuration option to TRUE

I tried running rio shapes on these images locally (outside of Docker) and it failed again. I'm going to double-check that they're out of the footprints database and move on.

[iandees]

Nothing in the footprints database, so closing this:

footprints=> select id,filename,resolution,source,url,min_zoom,max_zoom,priority,approximate_zoom from footprints where source='boem_gom_bathy';
 id | filename | resolution | source | url | min_zoom | max_zoom | priority | approximate_zoom

Re-opening for a rainy day.
