I like that it has many different levels, so if something comes up in your research or questions while using this software there are other layers for reference! Sometimes its hard working with GIS (even though i know my way around most), but once everything is set-up correctly we can get through all our tasks without any issues at hand!! If nothing else just keep going back into previous projects as well, because sometimes things will pop right out from under us due to an error/change made somewhere along down time ago. We used GeoManiVision during construction documents phase which was very helpful since they were already mapped before starting work; however now after completion more specific information such as topography needs updating & adding new features etc..
