To georeference something means to define its existence in physical space, that is establishing its location in terms of map projections or coordinates.
The term is used both when establishing the relation between aerial images and coordinates and also to determine the spatial location of other geographical features. Orthorectification removes distortions due to height, altitude of the aircraft and the terrain that has been photographed. This allows precise measurement in line with the scale of the photography. Orthorectified imagery is available to purchase, by contacting the Service Delivery team.
Spatial Services has access to specialised Radar, Light Detection and Ranging LiDAR data and satellite imagery which depict height information, vegetation, floods and other special conditions and features.
