Method Detail

runTest

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

Run the example code accepting an input LAS file and rendering a wire-frame diagram of the resulting triangular mesh, thinning the sample points so that a minimum pixel spacing is maintained.

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.

main

public static void main(String[] args)

Provides the main method for an example application that draws a color-coded image of a triangulated irregular network.

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
   -out    <file path>    optional output image file
   -width  <width>   optional image width, default 500
   -height <height>  optional image height, default 500
   -frame   <xmin xmax ymin ymax>  frame into sub-region of data

    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.
