Radiometric characteristic of Roman urban area and its coastal countryside as observed by landsat TM (1-4 wavebands) and ERS-1 SAR
Języki publikacji
Abstrakty
Landsat Thematic Mapper optical and ERS-1 SAR (image mode) radar data were analysed and compared to estimate their suitability to detect different types of land surface of the Roman urban and rural countryside area. Preliminary analysis of SAR data showed that speckle noise must be removed before radiometric analysis has been done. Radiometric analysis of such transformed data showed that the lowest values correspond to water, the highest to heterogeneous, urban areas; in the middle part of range are vegetated, homogeneous surfaces. Radiometric analysis of TM (1-4 wavebands) showed that it is very difficult to distinguish different types of land surfaces from raw data. Good results are obtained from NDVI map, where the lowest values of NDVI correspond to water, the highest to areas with dense vegetation. After the radiometric analysis and comparison of SAR and TM images has been done it seems to be possible to classify Roman urban and rural surfaces among three types: vegetated, unvegetated and water ones.
