A GIS analysis package for basic and advanced spatial analysis, an Image Processing system with extensive hard and soft classifiers including machine learning classifiers, integrated modelling environments including the Earth Trends Modeller for image time series of environmental trends and Land Change Modeller for land change analysis and ...
A Land Information System (LIS) is a geographic information system for cadastral and land-use mapping, typically used by local governments. [1]A LIS consists of an accurate, current and reliable land record cadastre and its associated attribute and spatial data that represent the legal boundaries of land tenure and provides a vital base layer capable of integration into other geographic ...
An extension to an existing database software program (most commonly, an object-relational database management system) that creates a geometry datatype, enabling spatial data to be stored in a column in a table, but also provides new functions to query languages such as SQL that include many of the management and analysis functions of GIS. This ...
SaTScan employs scan statistics to identify clusters of space and time phenomena. [1] Scan statistics use regular shapes (usually circles) of varying sizes to evaluate a study area. [ 8 ] [ 9 ] Within each circle, the software computes if the phenomena within the circle is significantly different than expected compared to the area outside the ...
Classically, a control is divided into horizontal (X-Y) and vertical (Z) controls (components of the control), however with the advent of satellite navigation systems, GPS in particular, this division is becoming obsolete. In the U.S., there is a national control network called the National Spatial Reference System (NSRS). [2]
The Polar Geospatial Center (PGC) was founded in 2007 and was originally called the Antarctic Geospatial Information Center (AGIC). In its early days, the AGIC's goal was to provide basic mapping and GIS services for the United States Antarctic Program (USAP), and was only a two-man project. As time went on, the program's credibility and size ...
Like the CGIS, early GIS installations in the United States were often focused on inventories of land use and natural resources, including the Minnesota Land Management Information System (MLMIS, 1969), the Land Use and Natural Resources Inventory of New York (LUNR, 1970), and the Oak Ridge Regional Modelling Information System (ORRMIS, 1973).
Geomatics engineers design, develop, and operate systems for collecting and analyzing spatial information about the land, the oceans, natural resources, and manmade features. [ 18 ] [ 19 ] Geomatics engineers apply engineering principles to spatial information and implement relational data structures involving measurement sciences, thus using ...
