@miguelcleon I am working on some maps for the field trip. Do you have a suggestion for the latest lidar or a pre-existing 30 m DEM I could use for terrain analysis?

[miguelcleon]

Here is the CZO LiDAR dataset: http://opentopo.sdsc.edu/datasetMetadata?otCollectionID=OT.102012.26920.1

I could share a 5 meter resampled of USGS DEMs with LiDAR I'll get a google drive link to share.

Thanks! This is for the entire island?

[miguelcleon]

No just the northeast.

[ChristinaB]

Oh... do you have a suggestion for Patillas area?

[miguelcleon]

I'd probably just try to find something here https://viewer.nationalmap.gov/basic/

@ChristinaB - there's always the SRTM data: https://www2.jpl.nasa.gov/srtm/

I haven't looked to make sure it's available for that area, but the resolution is probably 30 meters.

[miguelcleon]

yeah I've downloaded SRTM for the whole island.
