Geo Data Files

The data we will be working with comes from the US Census and is in a common shapefile format. A shapefile actually consists of 3 separate files with the same file name.

• filename.shp – Shapefile shape format, contains the actual geometry data.
• filename.dbf – Shapefile attribute format, this file stores the attributes for each shape. it uses the dBase IV format.
• filename.shx – Shapefile index, this file makes working with larger shapefiles faster. It contains no unique data, only an index of record offsets.

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.
