Method Detail

main

public static void main(String[] args)

Provides the main method for an example application that develops raster elevation files in Esri's ASCII format and image files in PNG format.

Data is accepted from an LAS file. For best results, the file should be in a projected coordinate system rather than a geographic coordinate system. In general, geographic coordinate systems are a poor choice for Lidar data processing since they are non-isotropic, however many data sources provide them in this form.

Command line arguments include the following:

   -in <file path>    input LAS file
   -frame xmin xmax ymin ymax frame for processing.

    Other arguments used by Tinfour test programs are supported
 

Parameters:

args - command line arguments indicating the input LAS file for processing and various output options.

runTest

public void runTest(PrintStream ps,
                    String[] args)
             throws IOException

Run the example code accepting an input LAS file and writing an output grid in Esri's ASCII raster format.

Specified by:

runTest in interface IDevelopmentTest

Parameters:

ps - a valid print-stream for recording results of processing.

args - a set of arguments for configuring the processing.

Throws:

IOException - if unable to read input or write output files.
