GIS is primarily used in urban and regional planning to manage and analyze spatial data, which includes information about land use, infrastructure, demographics, and other relevant factors.

While satellite imagery can be used in GIS for various purposes, it is not as commonly used in urban and regional planning as the other options, which provide more specific and relevant information for planning purposes.

Map overlay is the process of overlaying and combining different layers of spatial data in GIS to identify patterns, relationships, and insights that may not be apparent from examining each layer individually.

Site suitability analysis is a GIS tool that allows planners to evaluate the suitability of different locations for a particular land use based on various criteria and constraints.

Cartography is the art and science of creating maps, which involves the selection, generalization, and symbolization of spatial data to create visual representations that communicate information effectively.

Network analysis is a GIS technique that allows planners to analyze the connectivity and flow of movement through a network, such as a road network, to identify the shortest or most efficient path between two or more locations.

3D visualization is the process of creating a three-dimensional representation of spatial data in GIS, allowing planners to visualize and analyze the data in a more realistic and immersive manner.

Environmental impact assessment is a GIS tool that allows planners to assess the potential environmental impacts of a proposed development, such as its impact on air quality, water quality, and wildlife habitats.

Digitizing is the process of creating a digital representation of a real-world object or feature in GIS by manually tracing its outline or boundaries on a digital map.

Hot spot analysis is a GIS technique that allows planners to identify areas where a particular phenomenon or attribute is concentrated or clustered, helping them to identify areas of concern or opportunity.

Vectorization is the process of converting a raster dataset, which is composed of pixels, into a vector dataset, which is composed of points, lines, and polygons, allowing for more precise and detailed representation of spatial features.

Thematic mapping is a GIS tool that allows planners to create a map that shows the distribution of a particular attribute or phenomenon across a geographic area, using different visual variables such as color, pattern, and shape to represent the data.

Georeferencing is the process of assigning geographic coordinates to a digital map or dataset in GIS, allowing it to be accurately positioned and aligned with other geospatial data.

Spatial autocorrelation is a GIS technique that allows planners to analyze the relationship between two or more spatial variables, identifying patterns of similarity or dissimilarity in their distribution.

Interpolation is the process of creating a digital elevation model (DEM) in GIS by estimating the elevation values for locations where data is not available, using various mathematical techniques to generate a continuous surface representation of the terrain.
