GIS Glossary

Analytical functions that calculate statistics (mean, sum, etc.) for each cell in a raster based on its neighbourhood, used in raster-based spatial analysis (standard GIS usage).

The ground area covered by a spatial feature, such as a satellite image or building, important for overlay and area calculations (standard GIS usage).

The boundary or extent of a map or data view, important for defining the area of spatial analysis (standard GIS usage).

A table that summarizes the occurrence of attribute values or spatial features, supporting statistical and spatial analysis (standard GIS usage).

An approach in spatial analysis that allows for degrees of membership in classes, useful for modelling uncertainty and complex spatial phenomena (standard GIS usage).

The process of adding contextual geographic or demographic information to spatial datasets to enhance analysis

Computational methods used to determine optimal paths or routes in a spatial network, important for logistics and transportation analysis.

A widely used, text-based open standard format for encoding geographic data structures, facilitating data exchange and visualization.

The process of converting addresses or place names into geographic coordinates for mapping and spatial analysis.

A database designed to store, query, and manage spatial data, serving as the primary data storage model in many GIS platforms.

A coordinate system that uses latitude and longitude to define locations on the earth’s surface.

The spatial boundary or coverage area of a dataset or map, defining the limits of analysis.

A framework for capturing, storing, analysing, managing, and visualizing spatial and geographic data.

The spatial arrangement or distribution of features or phenomena on the earth’s surface, often revealed through spatial analysis.

A mathematical operation that converts data from one geographic coordinate system to another, ensuring spatial alignment.

A statistical technique that models spatially varying relationships, allowing for localized analysis of spatial data.

An XML-based standard for expressing geographic features, enabling data sharing and interoperability.

The process of examining spatial data to identify patterns, relationships, or trends across geographic space.

Techniques for efficiently storing and retrieving spatial data using spatial indexes, crucial for large datasets.

The analysis and visual representation of imagery and geospatial information to assess and describe physical features and activities.
