An example of an Arcpad form for a lithic locus (an area with a higher density of mostly-homogeneous stone artifacts) is shown with 25m contours and a 15m resolution ASTER satellite image in the background. For more information please see the Notes from my ArcPad and ArcGIS 8 development work.

We are recording polygons delimiting lithic, ceramic, and structural loci inside of site boundaries. In our approach a lithic loci may correspond with prehistoric activity areas, such as a place where obsidian was worked, and we are mapping them in by walking polygons around them with a GPS. With subsequent post-processing using this GPS approach we can delimit areas with 1-2m of accuracy. The Arcpad forms customized for this project can quickly record relevant locus attributes directly into the project GIS, eliminating the need for paper-based forms.
