TerrainWorks operates within two mediums:
(1) ESRI ArcMap 10.x using a single “add-in” (uses Virtual Watersheds)
(2) Online with web-based tools (TerrainViewer)
Required hardware/software: 64 bit computers, Windows 7, and ESRI ArcMap 10.x
NetMap Tools can be memory intensive, ranging from at least 4 GB of ram up to 16 to 32 GB for the more intensive tools
