About

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.

Tools

Input converter for Triangle

There is no 2 vertices per line limitation. Triangle handles duplicate points properly. No care was taken of that.

NLDAS-2 extractor

QGIS plug-in may not quite work as expected. Use standalone version for now.

Installation

Some tools in this plug-in (e.g., NLDAS-2 extractor) require extra Python packages (OPeNDAP/DODS client for GrADS Data Server at NOAA).

MS Windows

The following has been tested with QGIS from OSGeo4W.

  1. Install pip
  2. Install pydap
  3. cd %HOME%\.qgis\python\plugins
  4. git clone https://github.com/mlt/pihm_helper.git

If you don’t have git, just unpack downloaded archive over there.

Ubuntu GNU/Linux and alike

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.
