IHOD (Itasca Hydrologic Observation Dataviewer) was developed by Itasca specifically for groundwater data management. IHOD is a customizable QGIS plugin that merges high-level database input/output with tools for viewing hydrogeologic and geochemical data. It interacts directly with underlying databases to retrieve data and provide the user with intuitive access to those data in graphical and tabular formats that are readily integrated into the user's work flow.
QGIS is a free, open-source geographic information system (GIS) that provides a simple graphical platform to interact with a database management system. IHOD combines various tools that have been developed by Itasca using the Python scripting language and QGIS's extensive libraries to generate graphics, interact with database management systems, provide file input/output, and perform numerical and statistical analyses.
- It has the flexibility to populate a database from easy-to-use file formats. IHOD can be adapted to different data-file formats based on the client's needs.
- It is easy to retrieve data in an immediately useful format. IHOD can output data in a client-specified format.
- It adapts to the QGIS platform. IHOD uses the QGIS GUI platform and has a similar look and feel to GIS.
- The database is easy to transfer. A complete database may be converted to a portable database format or exported into an ASCII document containing complete instructions for rebuilding it. These methods provide a simple, fast, and error-resistant way to share data between networks or operate remotely.
