Abstract
The paper presents how urban infrastructure positional data collected by hand held GPS Receiver Garmin 12XL could be integrated and managed in GIS. In order to estimate hand held GPS positional accuracy, different GPS processing methods are evaluated. Experiment results show that horizontal accuacy 5m could be obtained with relative positioning method data which is collected in 1-1,5 minute period.
