Hydro GeoAnalyst (HGA) is our comprehensive and easy-to-use environmental data management system. HGA integrates customizable database structures used around the world with state-of-the-art tools for data interpretation, statistical analysis, Geographical Information System (GIS) mapping, data charting, and visualizations in two or three dimensions.
Hydro GeoAnalyst Plus (HGA+) integrates geochemistry features of AquaChem into the data management and extensibility capabilities of HGA.

HGA Additions:
The following features have been added or improved in both HGA and HGA+:
Cross Section Viewer:
The Cross Section Viewer Module allows you to export cross-sections as shapefiles for use in other applications.
New 64-bit module Cross Section Viewer allows you to build cross sections more efficiently:
- Define Cross Sections: Update older existing cross sections, pick from a list of stations to include in a new cross section, or define a cross section using the Map Viewer (see below)
- Interpretations: define cross sections along the same transect based on interpretations of the geology, hydrogeology, and/or model layers
- Auto-generate: automatically (re)build cross section interpretations based on intervals in applicable boreholes and intersecting cross sections
- Edit: edit and refine cross section interpretations using a variety of tools, including digitizing, snapping, and splitting
- Include Well Profiles: include custom well profiles for one or more boreholes along cross sections.
- Easy Migration: Automatically open existing cross sections developed in the legacy Cross Section Editor.
Map Viewer:
The Map Viewer module includes the following enhancements:
- Station Selection: if a station group is the active layer in the map, selections in the map are consistent with the station list, station picker, and other modules
- Create Station Groups: Create a static station group based on a selection in the Map Viewer
- SQL Queries: the Map Viewer allows you to more easily add queries with X/Y fields to the mapThe Map Viewer module has been enhanced to include:
Well Profile:
The Well Profile Module has been enhanced to include the automated Interval Validator:
- Automated Validation: automatically check intervals of geologic, well construction or other interval data for a selected station or station group for inconsistencies:
- Overlapping intervals: portions of the borehole with overlapping/duplicate intervals can be trimmed using the upper or lower intervals
- Gaps: portions of the borehole with missing information can be filled using adjacent intervals
- Preview Errors: each validation error can be selected and is displayed in its source table with a preview of where the error occurs
- Fix Errors: errors can be fixed manually or with tools to remove duplicates, trim overlap or fill gaps
Plot Collections:
The Plot Collection module includes the following enhancement:
- Plot Labels: plots with discrete data points include settings for data labels, for some, all, or none of the points
Import:
The Import module includes the following enhancements:
- Spreadsheet Data Import: importing spreadsheet (.xlsx/.xlsm) data files no longer requires MS-Office, Access Runtime, or the OLE DB driver as a prerequisite
- Import LAS: Log ASCII (LAS) files can be imported using 64-bit editions of HGA
- Import MON: Diver data (MON) files can be imported using 64-editions of HGA
Usability and Other Enhancements:
HGA and HGA+ include the following additional enhancements:
- Manage Databases: Improved usability for managing databases, including data source migration, backup, and restore options for users with sufficient privileges
- Lists: The Template Manager allows you to select an existing list so that multiple fields in different tables can share the same list as a requirement
- Data Filter: includes a setting to use station names instead of IDs and field aliases instead of database field names for improved readability
- Data Filter: allows admins to view information at for the whole database rather than just for the current project
- Queries: Read-only users can run SELECT queries
- Scene Viewer: Images include transparency settings
- Template Manager: the Template Manager allows you to use certain TSQL functions such as GetDate() as the default value for DATETIME fields
HGA+ Additions:
The following features have been added or improved in both HGA and HGA+:
Integrated Geochemical Modeling (PHREEQC):
HGA+ includes integrated cross-functionality with the basic features of PHREEQC, the popular geochemical modeling program developed by the USGS:
- The PHREEQC Module supports saving PHREEC (Basic) simulation configurations
- The modeled parameter picker in the Parameter Editor supports filtering and sorting
Usability and Other Enhancements:
HGA+ includes the following additional enhancements:
- Project Import: Upgrade AquaChem projects into HGA+
- Sample Import: Setting to define default symbol for newly-imported sample data
- Water Quality Standards: support for lower limits
Defects Addressed:
- Map Viewer:
- Maps from older projects do not load layer settings.
- Map Viewer does not save the visible status of image layers
- Groups on the Map Viewer are not saved
- ‘Quantities’ map symbols do not work for all decimal separators
- Map Viewer data provider:
- does not always return the correct min/max values when aggregating samples
- treats sample sets like station groups and incorrectly returns results for ALL samples at associated stations rather than just samples in the Sample Set
- Import:
- In some cases, the Update/Reject options are missing for existing/duplicate records when importing data using the General import method
- The cell formatting in Excel for Sample ID data can cause sample import to fail
- Plot Collection:
- Box and Whisker plot, automatic X-axis label title is always set to Stations
- Some Plot Collection settings were non-functional or unnecessary: these were repaired or removed as appropriate
- If you set a major or minor tick interval on a plot to 0, then the program will hang/crash…
- In some cases, AQT does not launch correctly from HGA
- SELECT distinct with multiple fields fails in advanced SQL queries
- HGA does not respond when recording Animated Plume Video in the Scene Viewer
- NaN values reported for some metals on unit conversion from ug/L > meq/L in sample results pane
- In some cases, the AquaChem 2014.2 import crashes without warning
- Water type calculation sometimes forces the project to reload rather than refresh the affected tables
- Inconsistency between Short/Long/Db names in HGA+
- Importing PHREEQC databases does not work with regional settings for countries using “,” as the decimal separator
- Errors may occur when running R-Console scripts with dynamic links to data queries when using the 64-bit Edition
- Map Viewer data provider does not always return the correct min/max values when aggregating samples
- Labels with for fields with spaces not supported in maps conflicts with space in added “parameter (unit)” fields
- Map Viewer data provider treats sample sets like station groups and incorrectly returns results for ALL samples at associated stations rather than just samples in the Sample Set
