The shapefile format is a geospatial vector data format for geographic information system (GIS) software.It is developed and regulated by Esri as a mostly open specification for data interoperability among Esri and other GIS software products. [1]
The Geospatial Data Abstraction Library (GDAL) is a computer software library for reading and writing raster and vector geospatial data formats (e.g. shapefile), and is released under the permissive X/MIT style free software license by the Open Source Geospatial Foundation.
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.
Shapefile – open, hybrid vector data format using SHP, SHX and DBF files (by ESRI) Spatial Data File – high-performance geodatabase format, native to MapGuide (by Autodesk ) TIGER – Topologically Integrated Geographic Encoding and Referencing
System for Automated Geoscientific Analyses (SAGA GIS) is a geographic information system (GIS) computer program, used to edit spatial data.It is free and open-source software, developed originally by a small team at the Department of Physical Geography, University of Göttingen, Germany, and is now being maintained and extended by an international developer community.
Keyhole Markup Language (KML) – XML based open standard (by OpenGIS) for GIS data exchange; MapInfo TAB format – MapInfo's vector data format using TAB, DAT, ID and MAP files; Measure Map Pro format – XML data format to store GIS data; National Transfer Format (NTF) – National Transfer Format (mostly used by the UK Ordnance Survey)
QGIS supports shapefiles, personal geodatabases, dxf, MapInfo, PostGIS, and other industry-standard formats. [5] Web services, including Web Map Service and Web Feature Service, are also supported to allow use of data from external sources. [6] QGIS integrates with other open-source GIS packages, including PostGIS, GRASS GIS, SAGA GIS, and ...
The Kentucky Open Data Portal is a site for exploring, accessing and downloading Kentucky-specific GIS data and discovering mapping apps. You can analyze and combine datasets using maps, as well as develop new web and mobile applications.
