Section XXIX-103 - Definitions

Base Map-a collection of one or more geospatial data layers that form the background of a cartographic presentation or form the basis for a geospatial data analysis.

Business Data-data (geospatial or otherwise) collected, purchased, developed, or maintained by an organization for the purposes of performing its work or accomplishing its mission(s).

Cartographic Presentation-the process of depicting or rendering geospatial data. This may include the production of paper maps, digital maps, websites, or other means of visualizing geospatial data.

Data Layer-a spatially integrated, areally distributed set of spatial data, usually representing one theme (water, transportation, etc.) or having a common set of attributes among spatial objects.

Department-the Louisiana Department of Transportation and Development.

Geographic Information System (GIS)-an integrated collection of computer software and data used to view and manage information about geographic places, analyze spatial relationships, and model spatial processes. A GIS provides a framework for collecting and organizing spatial data and related information so that it can be analyzed and displayed.

Geospatial-refers to the identification of the geographic location and characteristics of a feature on the earth. This information may be derived from, among other things, remote sensing, mapping, and surveying technologies. This also refers to approaches such as GIS for manipulating geographic data.

Geospatial Database-digital database containing information that identifies and incorporates the geographic location and characteristics of features on the earth and the metadata that describes them. This information may be derived from various sources, including GIS, GPS, remote sensing, mapping, and surveying technologies.

Mapping-the process, methods, and techniques of creating digital geospatial data from source material. The source may be derived from surveying, aerial photography, remote sensing data, or global positioning systems (GPS).

Metadata-data describing the content, quality, condition, and other characteristics of a dataset. Various metadata standards exist for different types of data. The geospatial metadata standard shall be as specified by the Federal Geographic Data Committee (FGDC) and posted on their website (http://www.fgdc.gov/metadata).

Raster Data-the representation of geospatial objects as collections of elements represented as rows and columns of data spaced apart from each other, usually on an equal linear interval in the x and y directions. Raster data can only represent data as accurately as the x and y dimensions of each cell will support.

Statewide Geodatabase of Louisiana-a digital database that contains the official geospatial data of Louisiana. These data represent statewide coverage of the topographic map features of Louisiana and are intended to provide consistent geographic data for use in geospatial analysis, cartographic presentation, and mapping for the state.

Vector Data-the representation of geospatial objects as sets of points, lines, or polygons. Lines can accurately represent linear features or edges of polygon features to the level of accuracy that is supported by the scale of the source data and the data collection technology.
