This extension combines image editor drawing tools with the possibilities of ArcMap. This creates some advantages above the default ArcMap functionality. In ArcMap it's possible to draw graphics but these are not saved in the underlying geodataset. The GRID Editor saves the drawings directly in the edit grid by changing the cell values. The ARIS GRID Editor extension adds a toolbar to ArcMap. This toolbar provides a set of tools to change the value of one or more cells. With these tools it is possible to: * draw a free line (pencil) * draw straight lines from one point to another * draw a solid polygon * change the value/color of a zone of cells with identical values (paintcan) * recover the original value of individual cells The Spatial Analyst extension is not required.

Bedmap2 is a significant improvement on the previous collection of Antarctic data—known as Bedmap. The product was a result of work led by the British Antarctic Survey, where researchers compiled decades worth of geophysical measurements, such as surface elevation measurements from NASA's Ice, Cloud and Land Elevation Satellite, known as...
