Mapping Toolbox 3.0

Import and Export Geographic Data

Mapping Toolbox imports a wide range of GIS and geospatial file formats, enabling you to read both vector and raster data into the MATLAB environment. The toolbox helps you reduce access time and improve memory usage by providing functionality for specific file types to read a portion of a file and downsample data prior to use. The toolbox supports georeferenced imagery and other raster data grids, including orthoimagery, satellite swath data, digital terrain elevation models, and various global data grids.

Mapping Toolbox also exports data to a number of file formats, enabling you to share data with applications such as Google Earth™ and ArcGIS. Using the toolbox with MATLAB or Image Processing Toolbox™ provides access to additional file formats.

File formats and data products supported by Mapping Toolbox include:

• Raster file formats, such as GeoTIFF, USGS DEM, DEM, DTED, Arc ASCII Grid, GTOPO30, ETOPO, and worldfile
• Vector file formats, such as ESRI shapefiles, KML, VMAP0, DCW, and GSHHS
• Selected data products, such as AVHRR and EGM96

File formats supported by MATLAB include:

• Image file formats, such as TIFF, JPEG, PNG, and JPEG2000
• Scientific data formats, such as NetCDF, HDF5, HDF4, HDF-EOS, and multiband files (BIP, BIL, BSQ)

File formats supported by Image Processing Toolbox include:

• Image file formats, such as NITF and HDR
