## Transform a shape file to a tiff file
|
|
If your input data is a processed shape file it first needs to be converted to geotiff, this can be done with the 'ShapeToGeoTiffTask'.
|
|
|
|
Pass the code of the shape item into the {code} parameter, this creates a new item with tiff data as a sibling of the shape item with the same parent
|
|
This new geotiff item should be used as input to the a task.
