Search for additional LiDAR

[scottyhq]

The initial focus was on USGS 3DEP https://www.usgs.gov/3d-elevation-program, but there are other sources of high-quality recent LiDAR:

• National Science Foundation's National Ecological Observatory Network (NEON) https://data.neonscience.org/data-products/DP3.30024.001 (2013 ->, ongoing)

  • NEON data api https://data.neonscience.org/data-api/

• OpenTopography https://portal.opentopography.org/dataCatalog

  • https://opentopography.org/developers

These are not STAC APIs, so similar to the WESM search, would need to have custom functions to load into geopandas.

Sort of unrelated but would using a service such as https://stac.geoplatform.gov/external/usgs-lidar-stac.s3-us-west-2.amazonaws.com/ept/catalog.json?.language=en be better for us to implement for 3dep search?

Thanks! Yes, I also came across geoplatform.gov recently. Currently, there is no API to search, it's just an App pointing at the static STAC catalog on AWS. Note for example, you can point a different STAC Browser at the same catalog:
https://radiantearth.github.io/stac-browser/#/external/usgs-lidar-stac.s3-us-west-2.amazonaws.com/ept/catalog.json?.language=en

But we should definitely keep an eye on it, and it might indeed be useful still for streamlining DeepDEM processing!
