4.2.4 Vector Data reprojection
This application allows to reproject a vector data using support image projection reference, or a user
specified map projection
Detailed description
This application allows to reproject 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
This section describes in details the parameters available for this application. Table 4.13, page 305
presents a summary of these parameters and the parameters keys to be used in command-line and
programming languages. Application key is VectorDataReprojection.

Table 4.13: Parameters table for Vector Data reprojection.
Input data
- Input vector data: The input vector data to reproject
- Use image keywords list: Optional input image to fill vector data with image kwl.
Output data
- Output vector data: The reprojected vector data
- Output Projection choice:
Available choices are:
- Use image projection ref: Vector data will be reprojected in image projection ref.
- Image used to get projection map: Projection map will be found using image
metadata
- User defined projection
- Output Cartographic Map Projection: Parameters of the ouptut map projection
to be used.
- Zone number: The zone number ranges from 1 to 60 and allows to define the
transverse mercator projection (along with the hemisphere)
- Northern Hemisphere: 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.
- EPSG Code: See www.spatialreference.org to find which EPSG code is associated
to your projection
Example
To run this example in command-line, use the following:
otbcli_VectorDataReprojection -in.vd VectorData_QB1.shp -out.proj image -out.proj.image ROI_QB_MUL_1.tif -out.vd reprojected_vd.shp
To run this example from Python, use the following code snippet:
#!/usr/bin/python # Import the otb applications package import otbApplication # The following line creates an instance of the VectorDataReprojection application VectorDataReprojection = otbApplication.Registry.CreateApplication("VectorDataReprojection") # The following lines set all the application parameters: VectorDataReprojection.SetParameterString("in.vd", "VectorData_QB1.shp") VectorDataReprojection.SetParameterString("out.proj","image") # The following line execute the application VectorDataReprojection.ExecuteAndWriteOutput()
