In order to write the graduation thesis, I was forced to help, I had to move ArcGIS to worship ArcGIS, and then be a special map with Arcmap. At first I thought it was to complete with "geoprocessing" in "Tools", who knows that it is not that kind of matter, to do a topic on that layer, just go to the "Properties" dialog box to complete it. Everything is so simple. The big company is doing the software is a cow, and our domestic software is really like a Baby that is uncomfortable.
