Some auxiliary tools for PIHM.
One of the shortcomings of official version is the inability to streamline the workflow. Steps like watershed delineation can be automated with sextante plug-in making it easy to use either GRASS GIS or TauDEM for that purpose. However standard PIHM plug-in tool expect data in certain format. The goal of this plug-in is to bridge that gap by providing missing functionality to help prepare input data for PIHM.
There is no 2 vertices per line limitation. Triangle handles duplicate points properly. No care was taken of that.
QGIS plug-in may not quite work as expected. Use standalone version for now.
Some tools in this plug-in (e.g., NLDAS-2 extractor) require extra Python packages (OPeNDAP/DODS client for GrADS Data Server at NOAA).
The following has been tested with QGIS from OSGeo4W.
- Install pip
- Install pydap
cd %HOME%\.qgis\python\pluginsgit clone https://github.com/mlt/pihm_helper.git
If you don’t have git, just unpack downloaded archive over there.
Note that Ubuntu has an older version of Pydap (2.x vs 3.x). You can
install pydap from PyPI using pip instead of sudo apt-get install python-dap.
