What is the difference between ArcView, ArcEditor, ArcInfo and ArcGIS?
This, admittedly, is one of the more confusing aspects of ESRI’s product line since the prefix “Arc” precedes most of the company’s products. Think of it this way: ArcGIS is a “suite” of GIS software, comprised of a number of applications that work seamlessly together (ArcMap, ArcCatalog, and ArcToolbox – described above) and distributed in three distinct license levels. ArcView is the basic license level of ArcGIS and is suitable for most GIS users. It contains dozens of tools for spatial analysis and is ready to use out of the box. For GIS practitioners requiring more analysis tools, ESRI offers the ArcEditor license level of ArcGIS which contains all of the functionality of ArcView, plus more. At the top of the hierarchy is ArcInfo which contains everything in ArcEditor but with the addition of sophisticated tools for truly scientific-level spatial analysis.
