Ordnance Survey Partner

Apogee Data Consulting became a licensed partner of Ordnance Survey (OS) in July 2005.

Some Ordnance Survey datasets are now available free of charge through OS OpenData.  Apogee Data Consulting can add value to these datasets by combining with other data as required by our customers.  For more information on OS OpenData pleaseclick here.

Digital data for use in GIS systems fall into two broad categories: VECTOR and RASTER. The type of data required depends on the purpose for which it is to be used.

Vector Data

Vector map data is created on computer. Individual map features such as roads, buildings and rivers are represented as points, lines and polygons. Therefore individual features can be selected and interrogated within a GIS system.

Raster Data

Raster data are cell-based spatial datasets, consisting of a regular grid of cells which cover an area. Raster datasets are best used as a background on which to display other data. Examples of raster formats are: jpeg and tiff files.
