As Caltrans is transitioning their spatial analysis and management of surveying data into a GIS, the process of converting original files into compatible formats is tedious and time-consuming. This project develops a geodatabase and creates a tool capable of converting and processing survey observations into the geodatabase. While maintaining all the original observations, the developed geodatabase allows efficient data retrieval and analysis of changes of elevation differences among benchmarks over time. The developed tool and geodatabase will be used by Caltrans to manage their surveying data along the Southern California transportation infrastructure.
