I'm having an issue with my Shape_Length field produced from the points to line tool. I have 23 sets of GPS locations that I converted into lines. I want to produce a field with the length in kilometers of each 23 polylines. My issue (at least from what I understand) is that the field is automatically generating a field based on the maps geometry, and producing numbers far below what I expect. I'm not sure what to change to get a Shape_Length field in kilometers. The map coordinate system and the system for each feature class is GCS WGS 1984.
I also tried adding a length field with the Add Geometry Attributes tool, but Length is not listed in the Geometry Properties drop-down menu.
I could either use help with knowing how what the unit conversion to kilometer is (if there even is one) or what to change to tell my feature I want kilometers.
I'm at the point where I've been scouring the internet and the software so long that I may probably missed something obvious and need to take the weekend to clear my head... Any help is appreciated!
