Introduction

The package add the following algorithms to 'processing' (was 'sexante'):

• Point Scatterers East-West Speed (ex PS VelEo)

  Model for the computation of the horizontal speed of PS in respect of the satellite.

• Point Scatterers Horizontal Speed (ex PS Velh)

  Model for the computation of the horizontal speed of PS in respect of the satellite. (?)

• Point Scatterers CR Index

  Model for the computation of the CR Index of satellite visibility

• Point Scatterers R Index

  Model for the computation of the R Index of satellite visibility

• Point Scatterers Projection Tools

  Model to compute speed projection for PS points

• Point Scatterers Projection Tools DDIR

Install

PSTools is installed as standard qgis plugin. The algoritms will be available in 'processing'.

• extract the repository in /.qgis2/python/plugins:

  $ git clone git://github.com/faunalia/pstools.git <home>/.qgis/python/plugins/
  

• install numpy and gdal python libraries.

  • tested with:

    • python-numpy Version: 1:1.6.1-6ubuntu1
    • python-gdal Version: 1.7.3-6ubuntu3

• enable 'processing' plugin from the qgis interface

• enable 'pstools' plugin from the qgis interface

Models

With the plugin are provides the following models:

• "?" ...

The models must be copied in /.qgis2/processing/models/ directory.

Testing

To run the unit tests:

    $ export PYTHONPATH=~/.qgis2/python/plugins:/usr/share/qgis/python/plugins
    $ cd ~/.qgis2/python/plugins/pstools
    $ python tests.py
