Data source The register is based on systematic field work by ZDRM members. The data are compared against archival material — particularly Italian and Yugoslav military archives, cadastral maps and topographic sheets from the Rapallo border period. The database is regularly updated.

LiDAR data — hosting provided by ZDRM

Elevation model visualisation for Slovenia, Italy and Croatia

The web map provides raster LiDAR layers (SVF — Sky-View Factor) for the entire Rapallo border area: Slovenia, Friuli-Venezia Giulia and Croatia. The data allow identification of fortification remains and terrain structures that cannot be detected with conventional base maps. The LiDAR data are hosted on ZDRM's own servers — this entails ongoing infrastructure and maintenance costs.
