GeoJSON [1] is an open standard format designed for representing simple geographical features, along with their non-spatial attributes.It is based on the JSON format.. The features include points (therefore addresses and locations), line strings (therefore streets, highways and boundaries), polygons (countries, provinces, tracts of land), and multi-part collections of these types.
TIGER logo. Topologically Integrated Geographic Encoding and Referencing, or TIGER, or TIGER/Line is a format used by the United States Census Bureau to describe physical and cultural features such as roads, highways, city limits, rivers, and lakes, as well as areas such as census tracts.
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
This was most common from the 1970s through the early 1990s, because GIS software developers had to invent their own geometry data structures, but incorporated existing relational database file formats for the attributes. For example, the Esri Shapefile format includes the .dbf file from the DOS dBase software.
Each shapefile can hold only one geometry type. The projection information contained in the .prj file is critical in order to understand the data contained in the .shp file correctly. Because shapefiles are widely used they can be combined with other geodata and used inside GIS (Geographic Information Systems), such as the open source QGIS ...
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 ...
