Furthermore, the model does not suffer from distortions unlike the raster data model. As vector geometries do not have a fixed layout, we can edit our features. Let's try it out by selecting the administrative boundaries layer in the Layers Panel and starting an edit session with the Toggle...
Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales. Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, well-crafted maps with cartography or GIS software. ...
Thespaghetti data modelwas one of the first conceptual models to add structure to features in a GIS. It was a simple GIS model where lines may cross without intersecting or topology without attributes. What are the advantages of raster data? A raster grid format is a data model for satellite...

The vector model is obviously entity-based, hence it is well suited to access a spatial database by using spatial entities as search keys. On the other hand, efficient space-oriented access may require sophisticated search structures and techniques. Early representations in vector data modeling, ...
Novel GIS-Based Model for Automatic Identification of Road Geometry in Vector DataRoad geometry, including tangents and curves, is essential information for many geospatial applications, such as traffic accident analysis, car navigation, and site selection and ranking. In accident analysis, drivers are...
