I'm a complete novice at GIS. My project is to find the highest peaks in each Antarctic territory, and compare the results with the international gazetteer to find which peaks are and aren't named.
I'm trying QGIS Desktop with Grass with the 200m resolution radar altitude DEM raster file. Locations are (x,y) from the south pole in metres.
The Gazetteer is https://data.aad.gov.au/aadc/gaz/scar/download.cfm and is available as CSV, GeoJSON (whatever that is) and KML formats. Locations are in latitude and longitude to the nearest minute of arc, which is not accurate enough.
Territories are given by longitude range in Wikipedia
I've succeeded in opening the DEM with QGIS. I could find peaks manually one at a time using colours and the "identify features" button.
But is there a better way?
