I would like to import horizontal and vertical measurements into GIS. Basically, it is a recording of change in the stratigraphy of an archaeological site. I measured across the excavation from a starting point to get the horizontal measurement and then down from that point to the feature I wanted to record. Each point therefore has two measurements (horizontal and vertical). Since the recordings were recorded on a vertical wall at a site, I don't have a GPS co-ordinate for the starting point.
Does anyone know how to do this?
