The vector layers used in ERDAS IMAGINE are based on the ArcInfo data model and consist of points, lines, and polygons. These layers are topologically complete, meaning that the spatial relationships between features are maintained. Vector layers can be used to represent transportation routes, utility corridors, communication lines, tax parcels, school zones, voting districts, landmarks, population density, and so forth. Vector layers can be analyzed independently or in combination with continuous and thematic raster layers.

In ERDAS IMAGINE, vector layers may also be shapefiles based on the ArcView data model.

Vector data can be acquired from several private and governmental agencies. Vector data can also be created in ERDAS IMAGINE by digitizing on the screen, using a digitizing tablet, or converting other data types to vector format.

See Vector Data for more information on the characteristics of vector data.
