Area and length measurement is very basic task in GIS. Almost every GIS software can do that. Things become harder if we want to calculate polygon volume in GIS. until few years ago, there is no simple and direct way to calculate polygon volume in GIS. Some GIS and Remote sensing software provide built in tool to do that, but these software usually have certain data format that is not easily converted into standard GIS format. Today the game has changed. Some developer has built a simple and intuitive plugin to calculate polygon volume using DEM as reference, and the most awesome aspect is, they made it in Quantum GIS / QGIS environment. This is a life saver because QGIS is a free software!. And here is my experience when I try those new developed plugin to calculate polygon volume in QGIS. ArcGIS doesnt have this luxury.
