Dear Dr. Vince Gaffney,

I suggest to you the SRTM Digital Elevation Model (DEM) 1 arc second, with approximately 30 meters of spatial resolution.

These DEM are made available by the USGS through the link:

https://earthexplorer.usgs.gov/

But if you want to work with a better resolution DTM/DEM, you should try ALOS PALSAR DEM. Available at: https://vertex.daac.asf.alaska.edu/

In both cases, the models cover almost every globe in full and most likely the Croatian islands of Palagruza are included.

Dear Leandro,

Many thanks for your kind suggestion. I shall certainly explore these suggestions. The islands are rather small but significant enough to require better data

Thank you

Vince

Hi Vince,

I remember that few geodesy students from Zagreb were surveying Palagruza with 2 professors in order to derive DTM. I think it was someones' undergraduate thesis. I'm really bad with remembering names but Kiro should remember that instantly.

Thanks Sara (and good to hear from you) - I'll try to jog Kiro's memory!

Optimist!

You can try the QGIS software to process the 30m resolution SRTM

Hi Leandro,

Many thanks indeed for this

Vince
