6. Analyzing Map Data > 6.3. Examining Data Content

Examining Data Content

Examining data content is an important part of any project. Understanding information specific to your dataset will help you use it more effectively. Each piece of spatial data will have some geographic component to it (coordinates describing the location of real features), but it will also have what are called attributes.These are non-geographic data about the geographic feature, such as the size of population, the name of a building, the color of a lake, etc. You will often hear the geographic coordinate data described as spatial data and the attribute information referred to as tabular, attribute, or nonspatial data. It is equally valid to call any dataset spatial if it has some geographic component to it.
