HgIS combines BI tools (Pentaho platform) and GIS. Technologies and tools used in HgIS are listed here.

Pentaho platform is a set of business intelligence tools.
It contains following components (download from SourceForge):

• Pentaho Data Integration (PDI, also known as Kettle)¹⁾ It is an ETL tool. It can read data from diverse databases, resources (e-mail, local computer, FTP, HTTP) and files (MS Excel, MS Access, CSV, TXT, ESRI SHP, XML, JSON, YAML, RSS, XBase or ZIP). Official resource lists all steps of transformations and jobs. Geospatial data can be handled with PDI GIS Plugins. See more info in Pentaho Data Integration Cheat Sheet.

• Pentaho Report Designer (screenshot).
  
  
• Pentaho Server (PBA, formerly BI Server, screenshot) is a key component of the platform. Dashboards can be executed here. Dashboard can be designed by CDE – more: Community Tools (CTools).
  
  
• Pentaho Metadata Editor – creates an abstract data layer. See a figure:
  
  
  

Machine Intelligence (blog post) utilizes engines: R, Python, Weka or Deeplearning4j (Java with GPU Nvidia).

Adaptive Execution Layer (AEL) runs transformations not only locally or on the Pentaho Server, but also on Spark. Dále Pentaho supports also cloud platforms like Amazon Web Services, Google Cloud Platform or Microsoft Azure (Cloud agnostic analytic pipeline). Alternative to AEL is Apache Beam.

• Java – programming language
• Apache Tomcat – web server
• JDBC – API for access to relational databases
• JNDI
• Jackrabbit: implementation of the Content repository API for Java
• Common Warehouse Metamodel – used in Pentaho Metadata – specification

• PostgreSQL is a database server we use. (PostgreSQL).
• We use DBeaver and pgAdmin for the database administration.
• PostGIS is a spatial extension to PostgreSQL database (PostGIS).

• QGIS – desktop GIS
• QGIS Server – map server
• EnviroInsite – advanced hydrogeological visualization. The company developing EI was acquired by the corporation developing EQuIS (EarthSoft). It does not plan to develop the standalone EI.²⁾ Therefore we plan to replace EI probably by QGIS with the Midvatten or FREEWAT³⁾ plugin.
