OrthoRectification-epsg otbcli_OrthoRectification OrthoRectification (epsg) Geometry This application allows ortho-rectifying optical images from supported sensors. ParameterRaster io.in Input Image The input image to ortho-rectify False OutputRaster io.out Output Image The ortho-rectified output image ParameterSelection map Output Cartographic Map Projection Parameters of the output map projection to be used. epsg 0 ParameterNumber map.epsg.code EPSG Code See www.spatialreference.org to find which EPSG code is associated to your projection 4326 ParameterSelection outputs.mode Parameters estimation modes autosize autospacing 0 ParameterNumber outputs.default Default pixel value Default value to write when outside of input image. 0 ParameterNumber elev.default Default elevation 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. 0 ParameterSelection interpolator Interpolation This group of parameters allows defining how the input image will be interpolated during resampling. bco nn linear 0 ParameterNumber interpolator.bco.radius Radius for bicubic interpolation This parameter allows controlling the size of the bicubic interpolation filter. If the target pixel size is higher than the input pixel size, increasing this parameter will reduce aliasing artefacts. 2 ParameterNumber opt.ram Available RAM (Mb) This allows setting the maximum amount of RAM available for processing. As the writing task is time consuming, it is better to write large pieces of data, which can be achieved by increasing this parameter (pay attention to your system capabilities) 128 ParameterNumber opt.gridspacing Resampling grid spacing Resampling is done according to a coordinate mapping deformation grid, whose pixel size is set by this parameter, and expressed in the coordinate system of the output image The closer to the output spacing this parameter is, the more precise will be the ortho-rectified image,but increasing this parameter will reduce processing time. 4
