Integration of Photogrammetry and Geographic Information System (GIS) in Digital Mapping Production


This research introduce the utilization of Geographic InformationSystem (GIS) and photogrammetry in digital map production. An aerialstereopair was used to produce an orthophoto by ERDAS LPS software.The Arc GIS software then used to prepare a digital map with multi layers for that study area. The produced map could be used and updated any time by GIS software. The research proved its effectiveness for integrating the GIS and photogrammetry in digital mapping since it is a time and cost consuming technique when it is compared to the conventional methods. Also the resulted accuracy ((Root Mean Square Error (RMSE)) was (35) cm which was suitable for large scale mapping.
