The shapefile format is a digital vector storage format for storing geographic location and associated attribute information. This format lacks the capacity to store topological information. The shapefile format was introduced with ArcView GIS version 2 in the early 1990s. It is now possible to read and write geographical datasets using the ...
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.
ESRI Shapefile; ArcInfo coverages; ArcSDE layers; Images; ArcIMS Services (e.g., Geography Network sources) ArcExplorer performs a variety of basic GIS functions, including display, query, and data retrieval applications. The ArcExplorer installation can be freely distributed on spatial data CDs so recipients can view data effectively.
Another development in the 1990s was the public release of proprietary file formats by GIS software vendors, enabling them to be used by other software. The most notable example of this was the publication of the Esri Shapefile format, [ 5 ] which by the late 1990s had become the most popular de facto standard for data sharing by the entire ...
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.

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.
