Hi, I posted this a while back and never got an answer. I installed ArcGIS Explorer a while back, and I'm wondering if it is possible to find all the values of a certain attribute of a flowline, in this case length in kilometers, and either export them to a program like Excel or add them up directly on ArcGIS Explorer. My goal is to find the total length of streams via Explorer. I cannot figure out how to do it. I am using the National Hydrography Dataset (NHD). Thoughts? Thanks in advance.
