Each of the variable-length records includes a record-header component and a record-contents component. A detailed description of the file format is given in the ESRI Shapefile Technical Description. [1] This format should not be confused with the AutoCAD shape font source format, which shares the .shp extension.
National Transfer Format (NTF) – National Transfer Format (mostly used by the UK Ordnance Survey) 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
The Spatial Data File (SDF) is a single-user geodatabase file format developed by Autodesk. The file format is the native spatial data storage format for Autodesk GIS programs MapGuide and AutoCAD Map 3D. As of 2014 SDF format version SDF3 (based on SQLite3) uses a single file. Prior versions of the format required a spatial index file (SIF ...
An open format that has become one of the most common formats for data sharing. IMG – ERDAS IMAGINE image file format; JPEG2000 – Open-source raster format. A compressed format, allows both lossy and lossless compression. MrSID – Multi-Resolution Seamless Image Database (by Lizardtech). A compressed wavelet format, allows both lossy and ...
The ability to work with an open format like GML is important to implementers because it gives alternatives to proprietary formats like Autodesk DWG files or ESRI Shapefiles. OpenJUMP nevertheless also reads and writes ESRI Shapefiles and supports ESRI ASCII grid format with an OpenJump plugin from the SIGLE team.
The table below provides an overview of notable computer-aided design (CAD) software. It does not judge power, ease of use, or other user-experience aspects. The table does not include software that is still in development (beta software).
File access: interfaces to various table, vector, image and grid file formats, including shapefiles, Esri grids (ASCII and binary), and many grid file formats supported by the Geospatial Data Abstraction Library , along with the native SGRD format of SAGA GIS. Filter for grids: Gaussian, Laplacian, multi-directional Lee filter.
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 ...
