I know it's late, but for others who have the same question. Please try this: # limit your computational region to polygon_vector r.mask vect=polygon_vector # clip big_raster to polygon_vector (MASK set by r.mask above) r.mapcalc ex=clipped_raster=big_raster # export r.out.gdal input=big_raster output=clipped_raster.tif.

The coordinate system defines how your raster data is projected. You can use the same coordinate system for your data so it will all be in the same projection. A raster dataset is projected into a new spatial reference using a bilinear interpolation approximation method that projects pixels on a coarse mesh grid and uses bilinear interpolation

This format is usually used for satellite imagery, aerial photography, elevation models and topographic maps. Introducing the Shapefile. The Shapefile is the most common format in GIS. It’s a vector format that can be read by almost all GIS systems. 2018-11-08 · With this system, you can apply standard raster processing tools and functions in ArcGIS, build custom functions and tools, and combine multiple tools and functions into raster processing chains to execute custom algorithms on large collections of raster data.

Prerequisite: Introduction to Geographic Information Systems (Geog 9003) or equivalent. Course Description:   A GIS data model enables a computer to represent real geographical elements as graphical elements.

ArcGIS applications, such as ArcMap, or datasets, such as mosaic datasets, can reproject on the fly. This is useful; however, each time a raster dataset is transformed, there is a change in the cells as they are resampled.
