Raster Analysis and Geoprocessing Concepts

These flashcards cover key vocabulary and concepts related to raster analysis and geoprocessing.

Raster Analysis

A method of analysis using raster data structures, where data is organized in a grid format.

Euclidean Distance

A measure of straight-line distance between two points in space, commonly used in GIS to calculate distances between raster cells and sources.

Reclassify Tool

A GIS tool used to change the values of cells in a raster dataset based on specified criteria.

Slope Tool

A GIS tool that calculates the steepness of terrain at each cell in a raster surface.

Aspect Tool

A GIS tool that determines the direction that the slope faces, expressed in compass degrees.

Map Algebra

A set of mathematical operations applied to raster data for spatial analysis.

Model Builder

A visual programming tool in GIS software for creating geoprocessing workflows and automating spatial analysis processes.

Zonal Functions

Functions that operate on zones within a raster based on values of the zones.

Global Functions

Functions that compute values based on the entire raster, rather than local neighborhoods.

Digital Elevation Models (DEM)

A type of raster data that represents the Earth's surface elevations for analysis in geographic information systems.
