  2. Shapefile - Wikipedia

    en.wikipedia.org/wiki/Shapefile

    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 ]

  3. GIS file format - Wikipedia

    en.wikipedia.org/wiki/GIS_file_format

    Vector file sizes are usually smaller than raster data, which can be tens, hundreds or more times larger than vector data (depending on resolution). Vector data is simpler to update and maintain, whereas a raster image will have to be completely reproduced. (Example: a new road is added).

    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

  5. Data model (GIS) - Wikipedia

    en.wikipedia.org/wiki/Data_model_(GIS)

    Each raster, or pixel, on the Mahomet Sand surface has a set of map coordinates that are recorded in a GIS (in the data model bin that is labeled "pixel coordinates", which is the raster corollary of the "geometry" bin for vector map data).

  6. GDAL - Wikipedia

    en.wikipedia.org/wiki/GDAL

    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.

  7. Geographic data and information - Wikipedia

    en.wikipedia.org/wiki/Geographic_data_and...

    There are also many different types of geodata, including vector files, raster files, geographic databases, web files, and multi-temporal data. Spatial data or spatial information is broader class of data whose geometry is relevant but it is not necessarily georeferenced, such as in computer-aided design (CAD), see geometric modeling.

  8. Geodatabase (Esri) - Wikipedia

    en.wikipedia.org/wiki/Geodatabase_(Esri)

    A geodatabase can contain spatially referenced data in vector or raster formats, or non-spatially referenced data in tabular format. [ 27 ] [ 28 ] Each dataset contains information about any number of individual items, but typically all of the items in a dataset are of the same theme (e.g., temperature measurements, roads in a city) and have ...

  9. QGIS - Wikipedia

    en.wikipedia.org/wiki/QGIS

    QGIS supports raster, vector, mesh, and point cloud layers. [4] Vector data is stored as either point, line, or polygon features. Multiple formats of raster images are supported, and the software can georeference images. QGIS supports shapefiles, personal geodatabases, dxf, MapInfo, PostGIS, and other industry-standard formats.
