Long Description

This application allows reprojecting a vector data using support image projection reference, or a user given map projection.
If given, image keywordlist can be added to reprojected vectordata.

Parameters

• Input data (in):

  • Input vector data (in.vd): The input vector data to reproject

  • Use image keywords list (in.kwl): Optional input image to fill vector data with image kwl.




• Output data (out):

  • Output vector data (out.vd): The reprojected vector data

  • Output Projection choice (out.proj):

    • Use image projection ref (image): Vector data will be reprojected in image projection ref.

      • Image used to get projection map (out.proj.image.in): Projection map will be found using image metadata

    • User defined projection (user):

      • Map Projection (out.proj.user.map): Defines the map projection to be used.

        • Universal Trans-Mercator (UTM) (utm): A system of transverse mercator projections dividing the surface of Earth between 80S and 84N latitude.

          • Zone number (out.proj.user.map.utm.zone): The zone number ranges from 1 to 60 and allows defining the transverse mercator projection (along with the hemisphere)

          • Northern Hemisphere (out.proj.user.map.utm.northhem): The transverse mercator projections are defined by their zone number as well as the hemisphere. Activate this parameter if your image is in the northern hemisphere.

        • Lambert II Etendu (lambert2): This is a Lambert Conformal Conic projection mainly used in France.

        • Lambert93 (lambert93): This is a Lambert 93 projection mainly used in France.

        • WGS 84 (wgs): This is a Geographical projection

        • EPSG Code (epsg): This code is a generic way of identifying map projections, and allows specifying a large amount of them. See www.spatialreference.org to find which EPSG code is associated to your projection;

          • EPSG Code (out.proj.user.map.epsg.code): See www.spatialreference.org to find which EPSG code is associated to your projection




• Elevation management (elev): This group of parameters allows managing elevation values. Supported formats are SRTM, DTED or any geotiff. DownloadSRTMTiles application could be a useful tool to list/download tiles related to a product.

  • DEM directory (elev.dem): This parameter allows selecting a directory containing Digital Elevation Model files. Note that this directory should contain only DEM files. Unexpected behaviour might occurs if other images are found in this directory.

  • Geoid File (elev.geoid): Use a geoid grid to get the height above the ellipsoid in case there is no DEM available, no coverage for some points or pixels with no_data in the DEM tiles. A version of the geoid can be found on the OTB website(https://gitlab.orfeo-toolbox.org/orfeotoolbox/otb-data/blob/master/Input/DEM/egm96.grd).

  • Default elevation (elev.default): This parameter allows setting the default height above ellipsoid when there is no DEM available, no coverage for some points or pixels with no_data in the DEM tiles, and no geoid file has been set. This is also used by some application as an average elevation value.
