2 Imagery

A common way of collecting information associated with a coverage, by which the value of a continuous phenomenon is usually sampled at regular but discrete locations, i.e. pixels.

3 Infrared

[remote sensing] An infrared image represents reflectance grid cells that are recorded in the near-infrared wavelengths, typically 0.7 to 1.1 micrometers.

4 Interoperability

The ability for two different software systems to interact with geospatial information.

5 Intersect Tool (Overlay)

[GIS proessing] The intersect tool is a GIS processing operation that uses two inputs to generate an output layer. It restricts the output similar to clip and preserves the attributes in both input layers.

6 ISO/TC 211 Geographic information/Geomatics

Standardisation in the field of digital geographic information. These standards may specify, for geographic information, methods, tools and services for data management (including definition and description), acquiring, processing, analysing, accessing, presenting and transferring such data in digital / electronic form between different users, systems and locations.
