متن کاملComparative Spatial Analysis of Positional Accuracy of OpenStreetMap and Proprietary Geodata
The emergence and ubiquitary availability of geotechnologies yield a rapid increase of user generated geographical data, utilized for mapping, modeling etc. On the example of a well mapped German city this paper analyzes the positional accuracy of OpenStreetMap and TomTom data by means of a statistical comparative approach using official survey data as the reference dataset. The results show th...
متن کاملAssessing the Positional and Thematic Accuracy of Remotely Sensed Data
Classification of remotely sensed imagery gives variable and often poor quality results. The causes and nature of these errors have been the subject of extensive research.. There are two different components of accuracy in the context of remote sensing: positional and thematic accuracy. Positional accuracy determines how closely the position of discrete objects shown on a rectified image (map) ...
