Download and install PIHMgis software
From Age of Water
See the Installation Guide (Macintosh/Windows) and the PIHMgis Download site.
Note to Mac Users:
- Separate installations of 3rd party libraries are not necessary with PIHMgis 3.0. Installation of QGIS on Macintosh requires installation of 3 libraries which are available from QGIS download page (GDAL and Matplotlib Python modules)
- In version 3, PIHMgis and QGIS (or any other GIS of users choice) are two separate applications, therefore there is NO PIHMgis toolbar in QGIS.
