Abstract. The primary problem for managers of digital topographic data is maintaining an accurate and up-to-date database. Traditional spatial-data-collection techniques and mapping procedures are expensive and, as a result, occur infrequently. However, the NAVSTAR Global Positioning System (GPS) now provides for the collection of timely, cost-effective spatial information. In this study, differential GPS data were collected for an area of rapid rural-to-urban land-use change by using low-cost GPS receivers in static and kinematic modes. These data were then processed for input to a geographic information system and assessed for their positional accuracy. It was found that GPS data collected in static mode and differentially corrected possessed a circular map accuracy standard (CMAS) of 3.62 m. These accuracies meet the requirements of many large-scale and medium-scale mapping programs.
