eMap Technical Specifications

System

eMap harnesses the power of the Smallworld Geographic Information System (GIS) data management software, including its search engines, ability to manipulate images, and its measuring and routing tools.

Aerial Photography

The quality of the eMap images has been made possible through high-resolution aerial camera technology, enabling orthophotographs to 0.125m Ground Sample Distance. Orthophotographs combine the visual qualities of photographs with the measurable characteristics of maps. 

Technical Specifications

Terralink International eMap includes aerial images of major metropolitan and urban areas with orthoimagery up to 0.125 metre GSD and positional accuracy of ±0.3 metre. Vector data linework has accuracy of +/-0.5 meters in metro areas.

Maintenance

Not only do we own seamless digital imagery of New Zealand, we re-fly, at regular intervals, constantly updating and improving the range and currency of eMap data.
