Satellite-detected surface features in Dronning Maud Land ice shelves
### General This dataset provides satellite-detected surface features in Dronning Maud Land Ice Shelves that have been digitized. We used **RADARSAT-2** imagery (Wide fine mode with approximate resolutions of 5-8 m) collected between **_13 November 2014_** and **_4 December 2014_**. These features w...

We used **RADARSAT-2** imagery (Wide fine mode with approximate resolutions of 5-8 m) collected between **_13 November 2014_** and **_4 December 2014_**. These features were categorized into 7 primary groups: (1) longitudinal stripes, (2) crevasses, (3) rifts, (4) ice rises and ice rumples, (5) blocks, (6) areas rich with above-mentioned features, (7) calving front. Because of high population of individual crevasses and rifts, we did not digitize all of them; we marked such high population areas and digitized some typical features to show their typical shapes and orientations. ### Feature Groups 1. **Longitudinal stripes** * Longitudinal stripe 2. **Crevasses** * Individual crevasses * Crevassed area 3. **Rifts** * Rift * Rifted Area 4. **Ice rises and ice rumples** * Isle-type ice rise and ice rumple * Promontory-type ice rise * Stripe on isle-type ice rise and ice rumple * Stripe on promontory-type ice rise * Cluster of small isle-type ice rises and ice rumples 5. **Blocks** * Iceberg * Area with many icebergs * Block within ice shelf 6. **Areas rich with above-mentioned features** * Area with crevasses and blocks * Area with crevasses and rifts * Area with crevasses and longitudinal stripes * Area with crevasses, rifts, and blocks * Onset area of short longitudinal stripes 7. **Calving front** * Calving front ### Date Formats The dataset has two separate shape files, (1) line features and (2) area (polygon) features.
