- DC-30 - Georeferencing and Georectification | GIS T Body of Knowledge
Georeferencing is the recording of the absolute location of a data point or data points Georectification refers to the removal of geometric distortions between sets of data points, most often the removal of terrain, platform, and sensor induced distortions from remote sensing imagery Georeferencing is a requisite task for all spatial data, as spatial data cannot be positioned in space or
- DC-10 - Aerial Photography: History and Georeferencing
Georeferencing is the process of assigning coordinate values to each pixel of the raster based image such as an aerial photograph that has been digitized on an image scanner or taken by a digital camera 2 Development of Aerial Photography In 1827, Joseph Nicéphore Niépce (pronounced Nee-ps) took the first photograph (Baatz, 1997)

- DA-31 - GIS T and Libraries, Archives, and Museums
Libraries, archives, and museums (LAMs) are an important part of the GIS T ecosystem and they engage in numerous activities that are critical for students, researchers, and practitioners Traditionally these organizations have been at the forefront of developing infrastructures and services that connect researchers and others to historical and contemporary GIS data, including print maps More
- DM-07 - The Raster Data Model | GIS T Body of Knowledge
The raster data model is a widely used method of storing geographic data The model most commonly takes the form of a grid-like structure that holds values at regularly spaced intervals over the extent of the raster Rasters are especially well suited for storing continuous data such as temperature and elevation values, but can hold discrete and categorical data such as land use as well The
- CV-15 - Web Mapping | GIS T Body of Knowledge
As internet use has grown, many paper maps have been scanned and published online, and new maps have increasingly been designed for viewing in a web browser or mobile app Web maps may be static or dynamic, and dynamic maps may either be animated or interactive Tiled web maps are interactive maps that use tiled images to allow for fast data loading and smooth interaction, while vector web
- PD-10 - Natural Language Processing in GIScience Applications
GIScientists are also able to leverage much of their existing expertise when processing natural language Knowledge of spatial relationships, regional hierarchies and geographic laws theories when combined with many leading NLP approaches result in cutting edge applications, many of which are actively used today In the section to follow, a number of different NLP techniques are discussed
