Getting the USGS 7.5" Topo API for use in After Effects

Hi,

I'm experimenting with an After Effects program that lets me create 3-D topographic map videos by accessing the maps using some kind of API - either BingMapsAPI, UniversalAPI, MapstackAPI, WmsAPI. I really like the USGS 7.5" maps on CalTopo, and i'm wondering if there's a way to get an API for it so that I can use it in my program?

Kind regards,

William Skea

    Possibly, a pro account (which it looks like you just signed up for) provides both WMTS access (possibly usable with the UniversalAPI), and WMS access (presumably usable with the WmsAPI, although significantly slower than WMTS).

    Click on your account name at the top left of the map viewer, then the "your account" tab of the dialog that comes up. At the bottom are WMS and WMTS links. For UniversalAPI, if it doesn't read the WMTS file directly, you may be able to use

    http://caltopo.com/api/ABC123/wmts/tile/t/{Z}/{X}/{Y}.png

    where ABC123 is the 6-digit account ID in both of the WMS and WMTS link,

    Hi Matt,

    Yep I signed up for it. The WMTS access isn’t usable with the Universal API, and yep WMS didn’t work either.

    Do you have any ideas for how I can load it onto my program? Is it possible to load the USGS map onto mapbox or mapstack and use one of their apis for it?

    Kind regards,

    Is there any documentation on the APIs that you can point me at?

    Hi Matt,

    Their developer was able to provide a solution this morning. It works with the universal api input.

    This is the URL they provided:

    http://caltopo.com/api/ABC123/wmts/tile/t/{z}/{x}/{y}.png<http://caltopo.com/api/ABC123/wmts/tile/t/%7BZ%7D/%7BX%7D/%7BY%7D.png>

    Kind regards,

    Great, looks it was just a question of capital vs lowercase tile parameters. Edited your comment to remove the reference to your API key.
