Current through Register Vol. 50, No. 6, June 20, 2024
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.
