Layer footprint

This tool creates a vector polygon footprint of the area covered by a raster grid or vector layer. It will create a vector rectangle corresponding to the bounding box. The user must specify the name of the input file, which may be either a Whitebox raster or a Shapefile, and the name of the output file.

If an input raster grid is specified which has an irregular shape, i.e. it contains NoData values at the edges, the resulting vector will still correspond to the full grid extent, ignoring the irregular boundary. If this is not the desired effect, you should reclass the grid such that all cells containing valid values are assigned some positive, non-zero value, and then use the Raster to Vector Polygons tool to vectorize the irregular-shaped extent boundary.

The following is an example of a Python script that uses this tool:

wd = pluginHost.getWorkingDirectory()
inputFile = wd + "input.dep"
outputFile = wd + "output.shp"
args = [inputFile, outputFile]
pluginHost.runPlugin("LayerFootprint", args, False)

This is a Groovy script also using this tool:

def wd = pluginHost.getWorkingDirectory()
def inputFile = wd + "input.shp"
def outputFile = wd + "output.shp"
String[] args = [inputFile, outputFile]
pluginHost.runPlugin("LayerFootprint", args, false)
