Geopositioning an object using a Correspondence Model derived from a set of points for which both ground and image coordinates are known.

Geospatial data, GIS data or geodata has explicit geographic positioning information included within it, such as a road network from a GIS, or a geo-referenced satellite image. Geospatial data may include attribute data that describes the features found in the dataset.There are two types of geospatial data - vector and raster.

Geospatial Data Infrastructure (GDI) is an initiative intended to create an environment in which all stakeholders can cooperate with each other and interact with technology, to better achieve their objectives at different political/administrative levels. GDI initiatives around the world have evolved in response to the need for cooperation between users and producers of geospatial data to nurture the means and environment for spatial data sharing and development. The ultimate objectives of these initiatives are to promote economic development, to stimulate better government and to foster environmental sustainability.

The information infrastructure and the institutional arrangement that a national geospatial information authority (such as MaCGDI) provides for geospatial users in implementing NSDI.

[software] Global Mapper was originally developed by USGS for the purpose of displaying elevation DEM data. It is a commercial GIS software product that allows users to view, edit, merge and export hundreds of supported file formats with flexibility.

A satellite based device that records x,y,z coordinates and other data. Ground locations are calculated by signals from satellites orbiting the Earth. GPS devices can be taken into the field to record data while walking, driving, or flying. 

A set of policies, standards, practices, technologies, and relationships to facilitate the flow of geographic data and information at all levels across government, academic, and private sectors globally. A linking of National Spatial Data Infrastructures.

Is all of the processes of governing, whether undertaken by a government, market or network, whether over a family, tribe, formal or informal organisation or territory and whether through the laws, norms, power or language of an organised society. 

[coordinate system] Graticules are lines of latitude or longitude on a digital or hard copy map and assist in showing the geographic locations of map features.

[coordinate system] The Greenwich meridian is a line of longitude that passes through the Royal Observatory in Greenwich, England. In a geographical coordinate system, it is a line of longitude defined to be 0°.

Linear distance between pixel centres on the ground.

Data about a feature collected in the field.

Acquiring data about features of interest in remote sensing by collecting ground-truth data in the field, inspecting aerial photography, additional maps, other ancillary data.
