Geographic information system ( GIS ) is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data.

The acronym GIS is sometimes used for geographical information science or geospatial information studies to refer to the academic discipline or career of working with geographic information systems.

In the simplest terms, GIS is the merging of cartography, statistical analysis, and database technology.

Generally, a GIS is custom-designed for an organization.

What goes beyond a GIS is a spatial data infrastructure, a concept that has no such restrictive boundaries.

While the use of layers much later became one of the main typical features of a contemporary GIS, the photographic process just described is not considered to be a GIS in itself – as the maps were just images with no database to link them to.

There is also a special GIS center in Fenwick Library which conducts GIS drop-in sessions every week.

* Modern digital GIS maps such as ArcMap typically project north at the top of the map, but use math degrees ( 0 is east, degrees increase counter-clockwise ), rather than compass degrees ( 0 is north, degrees increase clockwise ) for orientation of transects.

Therefore, text placement is time-consuming and labor-intensive, so cartographers and GIS users have developed automatic label placement to ease this process.

* GIS Day is held the third Wednesday of November during Geography Awareness Week.

TOXMAP is a Geographic Information System ( GIS ) that is part of TOXNET.

Since many factors are considered for landslide hazard mapping, GIS is an appropriate tool because it has functions of collection, storage, manipulation, display, and analysis of large amounts of spatially referenced data which can be handled fast and effectively.

Using satellite imagery in combination with GIS and on-the-ground studies, it is possible to generate maps of likely occurrences of future landslides.

* TOXMAP is a Geographic Information System ( GIS ) from the Division of Specialized Information Services of the United States National Library of Medicine ( NLM ) that uses maps of the United States to help users visually explore data from the United States Environmental Protection Agency's ( EPA ) Toxics Release Inventory and Superfund Basic Research Programs.

The project is planned to include an online mapping system that will enable users to perform GIS analysis and other tasks over the Internet.

In popular GIS software, data projected in latitude / longitude is often represented as a ' Geographic Coordinate System '.

The 185th Regiment is included in the Brigade Parachutists Folgore and is generally in charge of the training and preparation of units ; but it can be converted to other tasks depending on the technical and functional plan, from employment on land with the Commando Operations of Special Forces ( COFS ) and other units of river basin FS / FOS of the Army, with the Operating Group Incursori ( GOI ) of the Navy ( Marina Militare ), with the Incursori Unit of the Air Force and for some functions also with the Special Intervention Group ( GIS ) of the Police officers.

Its Digital Mapping Camera ( DMC ) supports photogrammetric data acquisition for a broad range of mapping, GIS, and remote sensing applications.

In a general sense, the term GIS describes any information system that integrates, stores, edits, analyzes, shares and displays geographic information for informing decision making.

He is also given credit for coining the term geographic information system and is recognized as the " Modern Father of GIS.

A GIS can be thought of as a system — it digitally creates and " manipulates " spatial areas that may be jurisdictional, purpose, or application-oriented.

Using GIS, extremely detailed maps can be generated to show past events and likely future events which have the potential to save lives, property, and money.

Small-scale rectangular raster image maps can have an associated world file for GIS map software which describes the location, scale and rotation of the map.

A geographic information system ( GIS ) can recognize and analyze the spatial relationships that exist within digitally stored spatial data.

LiDAR-derived products can be easily integrated into a Geographic Information System ( GIS ) for analysis and interpretation.

Users can interface with the software features through a graphical user interface ( GUI ) or by " plugging into " GRASS via other software such as Quantum GIS.

Recent versions of QGIS can be executed within the GRASS environment, allowing QGIS to be used as a user-friendly graphical interface to GRASS that more closely resembles other graphical GIS software than does the shell-based GRASS interface.

Terrain rendering: VisIt can read several file formats common in the field of Geographic Information Systems ( GIS ), allowing one to plot raster data such as terrain data in visualizations.

Areas of archaeological potential are often drawn on GIS maps which can indicate any potentially damaging development automatically.

All this information can be stored on computer GIS database and analysed and augmented as time goes by and further information is revealed.

: Geographic Information Systems, commonly referred to as GIS, provides a way in which archaeologists can visually represent archaeological data, and can be done in two ways: data visualization and representative visualization.

GIS can be used to merge census demographics or other data sources with the TIGER files to create maps and conduct analysis.

Geographic data is processed with Geographic information system ( GIS ) software which can, as one aspect of its functioning, produce maps.

Databases containing existing regional archaeological data as well as other landscape GIS layers such as soils, vegetation, modern features, and development plans can be loaded on a mobile GIS for referencing, for sampling purposes, and for groundtruth updating directly in the field, resulting a more informed archaeological survey process.

Using GIS, crime analysts can overlay other datasets such as census demographics, locations of pawn shops, schools, etc., to better understand the underlying causes of crime and help law enforcement administrators to devise strategies to deal with the problem.

GIS can refer to:

SAGA GIS can be used together with other GIS software like Kosmo to get better vector data and map producing capabilities.

SAGA GIS modules can be executed from within the statistical data analysis software R in order to integrate statistical and GIS analyses.

Esri uses the name ArcGIS to refer to its suite of GIS software products, which operate on desktop, server, and mobile platforms.

Landscape ecology relies on advanced technologies such as remote sensing, GIS, and models.

Clark Labs is engaged in the research and development on geospatial technologies including the development of computer software and analytical techniques for GIS and remote sensing with an emphasis on monitoring and modeling earth system dynamics.

# Spatial Analysis with Geographical Information System ( GIS ) and Global Positioning System ( GPS ) technologies

GIS technologies such as satellite imagery, thematic maps, and geospatial data play a big part in disaster risk management.

GIS specialises in Smart Card technologies for access control and electronic money.

These geographical information systems ( GIS ) include technologies such as cellphone GPS, RFIDs ( radio-frequency identification tags ), and geo-fences.

In cooperation with foreign scientists the Institutes is working out the system approach to forest management with the help of GIS technologies and databases characterizing the main components of forest biocenoses.

GISc addresses fundamental issues raised by the use of GIS and related information technologies ( Goodchild 1990, 1992 ; Wilson and Fotheringham 2007 ).

His research since 2000 increasingly has focused on integrating spatial technologies ( such as GIS ) into the humanities, developing an interdisciplinary approach to the study of space and place, and theorizing ways in which the emergent digital humanities can advance the study of religion and culture when framed by spatial considerations.
