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 ...
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 core of any GIS is a database that contains representations of geographic phenomena, modeling their geometry (location and shape) and their properties or attributes. A GIS database may be stored in a variety of forms, such as a collection of separate data files or a single spatially-enabled relational database. Collecting and managing these ...
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.
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.
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 .
The logo of the United States Geological Survey (USGS) The Geographic Names Information System (GNIS) is a database of name and location information about more than two million physical and cultural features throughout the United States and its territories; the associated states of the Marshall Islands, Federated States of Micronesia, and Palau; and Antarctica.
