Example of surface-level analysis: aspect from an elevation raster Each pixel in the new raster is filled with a value computed from the corresponding cell in the old raster, 1 –360º representing which compass direction that pixel faces. (North is both 1 and 360 . . . 0 is completely flat.) ANALYSIS EXTENT When performing analysis, the area of interest may be a portion of a larger raster dataset. If the area of interest is a portion of a larger raster dataset, the analysis extent can be set to encompass only the desired cells.

Note that we are multiplying the result with raster_boundary@1 at the end to discard pixel values outside of the state boundary. The output hosted image service is stored in raster store and shared on either the Raster Analysis Image Server or Image Hosting Image Server depending on the Enterprise configuration.

QGIS has some basic analysis capabilities built-in via Raster raster: Geographic Data Analysis and Modeling Reading, writing, manipulating, analyzing and modeling of spatial data. The package implements basic and high-level For example, your analysis may require an extraction of cells higher than 100 meters in elevation from an elevation raster. Groups of cells are identified by meeting a criteria of falling inside or outside a specified geometric shape. Calculatrice raster¶ Effectue des opérations algébriques à l’aide de couches raster. La couche résultante verra ses valeurs calculées en fonction d’une expression. L’expression peut contenir des valeurs numériques, des opérateurs et des références à n’importe quelle couche du projet en cours. The sp package is central for spatial data analysis in R as it defines a set of classes to represent spatial data.
