Dear all,
I’m new to this forum and new to 3D GIS, though I’ve been using ESRI software for some time. I am trying to use ArcMap and ArcScene to solve an archaeological issue: I need to link archaeological finds to their stratigraphic layers and excavation units.
I thought I could work with projections of the finds (points, XYZ data) and the layers/units (as 3d polygons) to cross information between both, by means of “select by location”, i.e. select all points that “are within” a certain layer or unit polygon. Indeed, I ended up with a selection of points/finds in ArcScene but apparently the elevation data of points was not taken into consideration, that is, all points within the polygon area (2D) were selected, regardless of their respective Z values. I also tried “Inside 3D”, with the same results.
So, my question at this point is: am I doing something wrong and/or skipping some important step of the process, or is ArcGis capable of/suitable for this type of operation at all? In other words, and assuming that my 3D projection of the finds (points) is correct (which would seem to be the case), are the polygons really 3D and Z aware, or only partly so, or not at all…?
Has anybody tried something like this before? Any contributions or comments would be much appreciated, I’m at a total loss right now. Thanks a lot for your time!
