Is there any solutions either on QGIS or ArcGIS? Thank you in advance. If the data has subtypes or domains those are honored by the attribute inspector. Being able to calculate the statistics of a multi-spectral image by the levels of a categorical spatial object (aka zonal statistics) is a very important tool on its own, thus users should know that they have an efficient implementation available in OTB (they do not in QGIS, for example, where this operation is performed for 1-layer rasters only). 4/ PostGIS 2. Scatter plots of individual mass balance values that comprise the means (shown by each histogram). Subject Author Created Replies Last message; huge file size with "-b 32" option in concatenation.

This is a grid with ones at the cells where the values are to be counted and zeros elsewhere: it should be clear that the zonal sum of these values counts the cells. One method. Created an NDVI raster layer into QGIS. Notice how GeoMedia breaks contours as major and minor – a neat feature.
