OpenStreetMap ( OSM) is a free, open geographic database updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace from aerial imagery and also import from other freely licensed geodata sources. OpenStreetMap is freely licensed under the Open Database License and as a result ...
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. As a library, it presents a single abstract data model to the calling ...
Files types[edit] Shapefiles : are a data exchange format created by ESRI and one of the most widely used GIS /geodata formats. One "shapefile" usually include four different files : .shp, .shx, .dbf, .prj. First three files must all be present in order to use the data. Each shapefile can hold only one geometry type.
ArcGIS is a family of client, server and online geographic information system (GIS) software developed and maintained by Esri . ArcGIS was first released in 1982 and as ARC/INFO, a command line-based GIS. ARC/INFO was later merged into ArcGIS Desktop, which was eventually superseded by ArcGIS Pro in 2015. [8]

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 shapefile format can spatially describe vector features: points, lines, and polygons ...
List of GIS data sources. 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.
Part 1: Finding the shape data. Method 1: Wikidata. Method 2: Using the OpenStreetMap website. Method 3: Using the OSM Relation Analyzer. Part 2: If you need to create the shape. Part 3: Embedding the shape into an article. Method 1: Using Wikidata. Method 2: Using Wikimedia Commons.
