Raster values, such as elevation, velocity, and temperature, are extracted to point features to identify geographic data at specific point locations. Raster data will not have all the characteristics of the features it displays. Non-spatial data. Additional non-spatial data can also be stored along with the spatial data represented by the coordinates of a vector geometry or the position of a raster cell.

The following table gives a description of the supported raster formats (raster datasets) and their extensions and identifies if they are read-only or if they can also be written by ArcGIS. In GIS recording the non-visible parts of the spectrum can be very useful. For example, measuring infra-red light can be useful in identifying water bodies. Because having images containing multiple bands of light is so useful in GIS, raster data are often provided as multi-band images.

What you choose may depend on what you’re doing. For example, if you’re using ArcMap and have a graphic, you can use the Clip button on the Image Analysis window. Raster data can be images (raster images) with each pixel containing a color value. In Raster, data is represented as a grid of (usually square) cells.

This video shows how to use map algebra for raster processing and analysis in geographic information systems (GIS). You will learn about raster calculation, Raster modules - GRASS GIS 7.8.6dev Reference Manual GRASS GIS 7.8.6dev Reference Manual Geographic Resources Analysis Support System, commonly referred to as GRASS GIS, is a Geographic Information System (GIS) used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. But first you need to take a crash course in GIS data. If you think the term GIS is vague, then you haven’t seen anything yet. There are a dizzying array of formats used for storing GIS data. Before we delve into the various formats let’s take a look at some fundamentals. Primarily there are two main types of GIS data: vector and raster.
