There are also many different types of geodata, including vector files, raster files, geographic databases, web files, and multi-temporal data. Spatial data or spatial information is broader class of data whose geometry is relevant but it is not necessarily georeferenced , such as in computer-aided design (CAD), see geometric modeling .
For approximately homogeneous data, the L function has expected value t and its variance is approximately constant in t. A common plot is a graph of t − L ^ ( t ) {\displaystyle t-{\widehat {L}}(t)} against t , which will approximately follow the horizontal zero-axis with constant dispersion if the data follow a homogeneous Poisson process.
Geospatial metadata (also geographic metadata) is a type of metadata applicable to geographic data and information.Such objects may be stored in a geographic information system (GIS) or may simply be documents, data-sets, images or other objects, services, or related items that exist in some other native environment but whose features may be appropriate to describe in a (geographic) metadata ...

Specifies, where present, the data source and data source format/datum, and optionally, the original data, presented in parentheses. This is initially primarily intended for use by geotagging robots, so that data is not blindly repeatedly copied from format to format and Wikipedia to Wikipedia, with progressive loss of precision and ...

The study of GIR systems has a rich history dating back to the 1970s and possibly earlier. See Ray Larson’s book Geographic information retrieval and spatial browsing [20] for references to much of the pre-Web literature on GIR. In 2005 the Cross-Language Evaluation Forum added a geographic track, GeoCLEF.
Statistical geography is the study and practice of collecting, analysing and presenting data that has a geographic or areal dimension, such as census or demographics data. It uses techniques from spatial analysis , but also encompasses geographical activities such as the defining and naming of geographical regions for statistical purposes.
