A Research Agenda for Geographic Information Science by Robert B. McMaster, E. Lynn Usery

By Robert B. McMaster, E. Lynn Usery

An in depth courting exists among GIS and diverse functions, together with cartography, photogrammetry, geodesy, surveying, laptop and knowledge technological know-how, and information, between others. Scientists coined the time period "geographic details technological know-how (GIScience)" to explain the idea at the back of those fields. A learn schedule for Geographic details technological know-how greatly information the problems and primary medical difficulties that needs to be solved if using GIS in those and different fields is to advance.

Immediately following the founding of the collage Consortium for Geographic info technological know-how (UCGIS), the crowd pointed out in a examine time table the subjects that represented significant demanding situations to the GIS learn neighborhood. the 1st bankruptcy of this booklet provides an creation to the schedule and to the collective information that the time table presents to researchers.

Chapters 2-10 speak about 9 unique examine demanding situations. Chapters 11-14 give you the foundation of the agenda's 4 "Emerging Themes." every one bankruptcy, written through researchers occupied with the belief of the subjects, discusses easy learn parts, the UCGIS technique, the necessity for the nationwide study schedule, contributions to wisdom and society, and gives an entire set of references.

The ultimate part attracts common conclusions in regards to the UCGIS strategy and the outlined examine demanding situations.

At the present time the most complete urban land use classification system is the “Land-based Classification System” (LBSC) developed by the American Planning Association (APA, 2004). Scientists should work closely with the FGDC to develop the Earth Cover Classification System. The Cultural and Demographic Content Standard should be implemented. Note that there are no standards associated with the collection of water quality, atmospherics, and snow/ice. 5 Single and Multiple Date Thematic Accuracy Assessment Cartographers and photogrammetrists are adept at specifying the spatial positional accuracy (x,y,z) of a geographic observation in terms of root-meansquare-error (RMSE) statistics or circle of uncertainty.

5 Single and Multiple Date Thematic Accuracy Assessment Cartographers and photogrammetrists are adept at specifying the spatial positional accuracy (x,y,z) of a geographic observation in terms of root-meansquare-error (RMSE) statistics or circle of uncertainty. Scientists are also fairly adept at estimating the accuracy of an individual thematic map when compared with in situ “ground-reference” information using statistics such as the kappa coefficient-of-agreement (Stehman, 2000; Gahegan and Ehlers, 2000; Green and Congalton, 2003).
