Integration of a GIS Data Set with Aerial Photography Using GPS for Control Points on the Newlands Project in Nevada


This paper examines issues related to the integration of data that is of a higher resolution than an existing GIS data set. It concerns a GIS data base that was created nearly ten years ago. The base data layer for several GIS themes was initially captured using coordinate values from maps at a scale of 1:62 500. This base data layer represents survey information of bearing and distance measurements. Additional features were captured from a set of aerial photography at a scale of 1:7920. GPS units will be used to capture coordinates for registration of this photography for incorporation into the existing GIS data base. At the same time, the coordinate data captured by the GPS units provide an opportunity for improving the representation in GIS of the survey information.
