See Migrate from ArcMap to ArcGIS Pro for more information.A raster catalog is a container for raster datasets (for example, grids, DEMs, or imagery). Raster catalogs can be created as unique objects within a geodatabase (the recommended method), or they can be defined using a table. ...
map = ArcGISMap(Basemap(rasterLayer)) // Alternatively, you could add the raster layer as an operational layer. // map.operationalLayers.add(rasterLayer) }.onFailure { Log.e(localClassName, "Raster layer failed to load.") } } You can add a raster layer to a map as either a basemap...
Click the Georeferencing drop-down menu and click Fit To Display. This displays the raster dataset in the same area as the target layers. You can also use the Shift and Rotate tools to move the raster dataset as needed. To see all the datasets, adjust their order in the table of...
Pixel values are remapped by specifying a range of pixel values to map to an output pixel value. The output pixel value can be a valid value or a NoData value, which are pixels that do not have a known value associated with them. Sample This tool creates a table or a point feature ...
The Extract Values To Table tool extracts the cell values from a set of rasters by referring to a set of point or polygon feature class. The values are recorded in the attribute table of the output feature class. In ArcGIS Pro, click the Analysis ribbon and click the Tools ico...
