OS MasterMap® GML is a specific type of GML and so wherever possible GML convertors built specially for OS MasterMap® should be used. GML can be used to store and display geographic data in a GIS or just to transfer spatial data from one system to another. GML is based on XML (Extensible Markup Language), which was designed to improve the functionality of the Web by providing a more flexible way of identifying and describing information (for more information on XML, see the World Wide Web Consortium website). GML has been designed by the OpenGIS Consortium (OGC) to provide an open spatial data schema to enable interoperability between independent GIS applications and with internet GIS in mind. GPKG (GeoPackage)Ī GeoPackage is an open, non-proprietary, platform-independent and standards-based data format for geographic information system implemented as a SQLite database container. GDB (File Geodatabase)ĮSRI File Geodatabase format. EPS data can be used in Adobe Systems products (Illustrator, Photoshop and InDesign), CorelDRAW, Ghostscript, GIMP (GNU Image Manipulation Program) and others. EPS (Encapsulated PostScript)Ī DSC (Document Structuring Conventions)-conforming PostScript document most often used as a graphics file format. Native binary format for AutoCAD but can also be read by many other CAD and GIS software. DXF data can be imported into most CAD and GIS software, including Esri ArcGIS products, MapInfo, MapMaker, Cartology and Idrisi. “NHS_Authority”, “Domestic_Delivery_Points”, “District”…etc “SS9”,”33”,”QP” …etc DXF (Autocad Drawing eXchange Format)Īn industry standard ASCII text based interchange file format used to transfer data between CAD and GIS applications. ASC data can be imported into most GIS software, including Esri ArcGIS products, MapInfo, AutoCAD Map3D/Civil3D, GRASS, QGIS and Idrisi. The format consists of a header that specifies the geographic domain and resolution, followed by the actual grid cell values.
#Mapinfo and arcgis code#
ASC (ASCII American Standard Code for Information Interchange)Ī standard binary coding system used to represent characters within a computer. Each grid cell is referenced by its x,y coordinate location. Each grid point stores a numeric value that represents a geographic attribute (such as elevation or land cover) for that point. The grid defines geographic space as an array of equally sized square grid points arranged in rows and columns. Format list ArcInfo (ESRI ArcInfo)ĪrcInfo format is a proprietary binary raster grid format developed by ESRI. The list below provides guidance on the available formats. Data can be downloaded from Digimap in a number of different formats.
