Spatial Data File – high-performance geodatabase format, native to MapGuide (by Autodesk) TIGER – Topologically Integrated Geographic Encoding and Referencing Vector Product Format – National Geospatial-Intelligence Agency (NGA)'s format of vectored data for large geographic databases
In each of the .shp, .shx, and .dbf files, the shapes in each file correspond to each other in sequence (i.e., the first record in the .shp file corresponds to the first record in the .shx and .dbf files, etc.). The .shp and .shx files have various fields with different endianness, so an implementer of the file formats must be very careful to ...
The file format is the native spatial data storage format for Autodesk GIS programs MapGuide and AutoCAD Map 3D. As of 2014 [update] SDF format version SDF3 (based on SQLite3 ) uses a single file. Prior versions of the format required a spatial index file (SIF), with an optional key index file (KIF) to speed access to the file.
A GIS file format is a standard for encoding geographical information into a computer file, as a specialized type of file format for use in geographic information systems (GIS) and other geospatial applications. Since the 1970s, dozens of formats have been created based on various data models for various purposes
Plugins are provided for Autocad (for designers), ArcGIS, open source QGIS (for analysts & designers) and as a standalone Python version that works on 2D or 3D shapefiles enabling use in other GIS software and custom projects. sDNA standardizes on the network link as a unit of analysis, and computes a wide variety of closeness, betweenness ...
A shape-"file" actually consisted of several files, including at the very least a .shp file to store the geometry, and a .dbf file for the attributes, the latter directly adopting the dBase format that was the dominant microcomputer database at the time (despite it being a proprietary trade secret, the .dbf format had been legally reverse ...
This is typically done with a set of metadata parameters, either in the file header (such as the GeoTIFF format) or in a sidecar file (such as a world file). At the very least, the georeferencing metadata must include the location of at least one cell in the chosen coordinate system and the resolution or cell size , the distance between each cell.
System for Automated Geoscientific Analyses (SAGA GIS) is a geographic information system (GIS) computer program, used to edit spatial data.It is free and open-source software, developed originally by a small team at the Department of Physical Geography, University of Göttingen, Germany, and is now being maintained and extended by an international developer community.
