Hello,
We are using ArcMap 10.1.
We are new to Esri ArcMap and really anything GIS. We have a need for maps, elevation data, LIDAR and topo information. We have been using usdaNRCSGeospatial Data Gateway, National Map Orthoimagery, GIS Data Depot and local government GIS websites. We have recently heard of ArcCatalog and wondered what other resources there are for basic GIS data as described above, that a non-GIS professionals can access?
