GIS data for State of Kentucky; Name Description; Kentucky Geography Portal: The Kentucky Geoportal is a Data Clearinghouse that provides ays to discover and share geospatial data resources. Locate maps and geographic data content for a particular part of the state or search based on keyword or theme type. [12] Kentucky Open Data Portal
The CGIS has worked on projects for the 1999 Color Infra-Red (CIR) Digital Ortho Photo Program, for the Georgia GIS Data Clearinghouse, for the NWI-Wetlands statewide digital wetland database with GIS tools, for the Trees Atlanta-Greenspace Acquisition Support System, the U.S. Environmental Protection Agency-Air Quality, natural hazards ...
Currently, the best source for nationwide LiDAR availability from public sources is the United States Interagency Elevation Inventory (USIEI). [1] The USIEI is a collaborative effort of NOAA and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency, the Natural Resources Conservation Service, the US Army Corps of Engineers, and the National Park Service.
Unlike the NSDI Clearinghouse Network, GOS was built around a centralized metadata catalog database, with an architecture that links users to data providers through a Web-based geoportal. The user of GOS may employ a simple Web browser (thin client) or may interface directly with a GIS (thick client).
The origin of the geodatabase was in the mid-1990s during the emergence of the first spatial databases.One early approach to integrating relational databases and GIS was the use of server middleware, a third-party program that stores the spatial data in database tables in a custom format, and translates it dynamically into a logical model that can be understood by the client software.
The TIGER files do not contain the census demographic data, but merely the geospatial/map data. GIS can be used to merge census demographics or other data sources with the TIGER files to create maps and conduct analysis. TIGER data is available without cost because U.S. Government publications are required to be released into the public domain.
The Open Geospatial Consortium (OGC) is an international voluntary consensus standards organization that develops and maintains international standards for geospatial content and location-based services, sensor web, Internet of Things, GIS data processing and data sharing. The OGC was incorporated as a not for profit in 1994.
There are also many different types of geodata, including vector files, raster files, geographic databases, web files, and multi-temporal data. Spatial data or spatial information is broader class of data whose geometry is relevant but it is not necessarily georeferenced , such as in computer-aided design (CAD), see geometric modeling .
