WebJul 5, 2024 · It was observed in the study that the data sets made by adding DEM or polarimetry data to ASTER data had greater accuracy values than the accuracy of Data Set 2 which has VNIR, SWIR, and TIR bands of ASTER. Data Set 3, made with DEM data added to ASTER data, yielded greater accuracy than Data Set 4, which was made by … WebOne of the most important characteristics of ASTER is its high resolution--a pixel size of 15 m for bands 1-3 (compared to Landsat's 15 to 30 m resolution). High resolution is useful for park managers because it provides more detail and, consequently, greater ability to detect changes and to observe the status of the park.
