What are raster data in the context of GEOINT?

Raster data in the context of GEOINT refers to data represented in grid format. This type of data consists of a matrix of cells or pixels, each containing a value that represents information, such as satellite imagery, elevation data, or temperature readings. The grid format allows for continuous data representation across a defined area, making it particularly useful for capturing variations in space, such as land cover or topography. Raster data is often utilized in various analyses, including environmental monitoring, urban planning, and resource management, due to its ability to handle large amounts of data effectively and its compatibility with remote sensing applications.

In contrast, vector data consists of points, lines, and polygons that define specific geographic features and their attributes, while tabular format conveys data in rows and columns, commonly used for databases. 3D models represent three-dimensional objects or environments, which serve a different purpose in visualization or simulation. Thus, the grid format of raster data is key to its function and utility in the field of GEOINT.
