Geographic Data

Geographic data is about much more than electronic pictures of maps. The geographic data that describes our world allows for city planning, flood prediction and relief, emergency service routing, environmental assessments, ...

Analysis of Geographic Data ANALYSIS - What? & Why? The heart of GIS is the analytical capabilities of the system. What distinguish the GIS system from other information system are its spatial analysis functions.

Geographic databases (themes) can be used to solve problems like: Site Location Visualizing customer locations is critical to businesses trying to make better marketing decisions.

Geographic data is distinguished from attribute data in that it is referenced spatially by a coordinate system, e.g. it has a spatial extent. Natural resource applications commonly use a Legal Survey system, e.g.

Geographic data representing each of the three possible vector types (points, lines, and polygons) of the earth's surface can be found in the SRP GIS.

Geographic Data The locations and descriptions of geographic features. The composite of spatial data and descriptive data. Geographic Feature ...

GEOGRAPHIC DATA Any information which includes a description of a location on or near the Earth's surface. This may include generic descriptions, for example, place names or particular geological strata. GEOGRAPHIC INFORMATION SYSTEM See GIS.

geographic data set One of seven geographic data types supported by ARC/INFO. Geographic data sets in ARC/INFO include coverages, grids, DBMS tables, tins, images, lattices, and CAD drawings.

Grid: A geographic data model representing information as an array of equally sized square cells arranged in rows and columns. Each grid cell is referenced by its geographic x,y location.

Grid - A geographic data model represented as an array of equally sized square cells arranged in rows and columns. Each grid cell is referenced by it geographic x, y location and contains one data value, such as elevation.

Seamless geographic database - The method of organizing geographic data in such a way that the data physically stored as individual files, known as tiles, can be retrieved as if they were in one single file or database.

Coverage- Geographic data set that represents a specific type of feature (e.g., vegetation coverage). Often simply called a layer. ARC/INFO also has a data format that is referred to as a coverage.

Given that geographic datasets are primarly concerned with spatial references, we really must have metadata (data about the data) describing the coordinate system that is embedded in the files.

State Soil Geographic Database (STATSGO) State general soil maps made by generalizing the detailed soil survey data. The level of mapping is designed to be used for broad planning and management uses covering state, regional, and multi-state areas.

State Soil Geographic database (STATSGO) was digitized from 1:250,000-scale topographic maps, on which a generalization of the detailed soil surveys was mapped.

Before geographic data can be used in a GIS, the data must be converted into a suitable digital format. The process of converting data from paper maps into computer files is called digitizing.

The National Geographic Data Framework (NGDF), recently established in the UK, is producing a series of guidelines for the definition and storage of spatial data such that it has maximum potential for future use.

GIS organizes geographic data into a series of thematic layers and tables. Because data in a GIS are referenced to geography, they have real-world locations and could overlay one another.

Conceptually, geographic data can be broken up in two elements: observation or entity and attribute or variable. GIS have to be able to manage both elements.

Typical sources of geographic data for computer manipulation include digitized maps, field survey data, aerial photographs (including infrared photographs), and satellite imagery. Most image data are collected using remote sensing techniques.

Geographic Data The composite locations and descriptions of geographic entities. Geographic Database Efficently stored and organized spatial data and possibly related descriptive data.

Digital Geospatial Metadata - DGM: DGM was approved in June 1994 by the Federal Geographic Data Committee (FGDC). DGM describes the specifications for the content, quality, condition, and other characteristics of metadata.

A standard vector format developed by the US Federal Geographic Data Committee.

18 a collection of related geographic data. Depending on context, a layer may have some specific relationship to other layers. For raster imagery, a layer can represent one sensor in a multispectral array.

geographic data. Data that convey the locations and descriptions of geographic features. geographic information system (GIS).

Maps and geographic data capture the essence of the geographically particular, the boundary conditions that influence the outcome of physical and social processes; and in that sense GIS illuminates the particular.

The Internet has introduced a new dimension in the use of geospatial information by coupling fast and widespread dissemination of geographic data with accessible GIS tools.

Viewing and printing geographic data at user designed scales and sizes. Searching and selecting geographic features of interest based on subject queries, logical queries, arithmetic queries, and spatial relationships.

This data set is a digital version of the county soil survey and is generally the most detailed level of soil geographic data developed by the SJRWMD and National Resources Conservation Service (NRCS).

[ESRI software] A container for geographic data. A workspace can be a folder that contains shapefiles, a geodatabase, a feature dataset, or an ArcInfo workspace.

These digital cartographic and geographic data may also be used as one layer in a geographic information system (GIS), as a tool for various kinds of spatial analyses, and as information for plotting base maps.

(ISO/TC211) is developing international Geographic Information/Geomatics standards. Among many other computing standards, ISO maintains an SQL standard and is developing an extended version, SQL3, which will support queries on geographic data sets.
