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]
A Geodatabase is a proprietary GIS file format developed in the late 1990s by Esri (a GIS software vendor) to represent, store, and organize spatial datasets within a geographic information system. [ 1 ] [ 2 ] A geodatabase is both a logical data model and the physical implementation of that logical model in several proprietary file formats ...
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
Shapefile (Esri 1992–present) As the GIS industry grew to incorporate more casual users, the inherent complexity of the coverage data structure became a concern. When Esri released ArcView GIS 2.0 in 1992, it introduced the new shapefile format for vector data. This was a much simpler data model, eliminating features such as topology, but was ...
Esri’s ArcGIS platform has provided GIS data, analytics software, and training to thousands of non-profit organizations and individual conservation projects since 1993. [ 31 ] In 2017, Esri began a partnership with the United Nations General Assembly (UNGA) to create a data hub, Federated Systems, based on Esri's ArcGIS platform.
This is a list of GIS data sources (including some geoportals) that provide information sets that can be used in geographic information systems (GIS) and spatial databases for purposes of geospatial analysis and cartographic mapping. This list categorizes the sources of interest.
ArcIMS (standing for Arc Internet Map Server) is a Web Map Server produced by Esri accessible through a web browser. It is a GIS that is designed to serve maps across the Internet. Sometimes these maps are just static images allowing simple panning and zooming, while others are more complex pages.
[10]: 215 It was common in early GIS systems such as the Map Overlay and Statistical System (MOSS) as well as most recent data formats, such as the Esri shapefile, geography markup language (GML), and almost all spatial databases. In this model, each feature geometry is encoded separately from any others in the data set, regardless of whether ...
