Summary
Gravity measurements indicate subtle differences in the density of rocks in Earth's crust. The gravity anomaly can be used to indirectly map the distribution of different rock types. Please follow links on this page to download image (GeoTiff or kmz), grid (gxf) or flight line (csv) data. Detailed information regarding data collection and processing can be found in the technical report.
