Course Description (An Introduction to Environmental Data Management)
There is increasingly greater amounts of data available to characterize environmental problems. These data come in many different formats (hard copy reports, electronic databases, spreadsheets, field investigation results, …) which can make it difficult to integrate and analyze. The purpose of integrated environmental data management is to acquire, store and analyze environmental data to develop a conceptual hydrogeologic model of a site so that we can design a solution to an environmental problem (e.g. environmental planning, modeling, remediation, …).
This 3-day hands-on course presents an introduction to the management and analysis of environmental data using HGA. Data management begins with the development of a site GIS, using HGA, that integrates the many disparate sources of groundwater data that are common in a hydrogeologic analysis. The data are then interpolated and mapped in HGA to generate the conceptual hydrogeologic model of the study site. The hydrogeologic conceptualization can then be used in site characterization, regional hydrogeologic analysis and in the development of groundwater models. Course topics include database management, borehole log plotting using Map Manager, and cross section analysis. Other topics that will be covered include 2-D and 3-D visualization and animation of the hydrogeologic conceptual model. This course is ideally suited for environmental professionals who wish to develop a more comprehensive understanding of the data sources that are used in hydrogeologic analysis, the interpolation of this data in GIS, and the interchange of information between the GIS system and groundwater models.
Data Management
Hydro GeoAnalyst embeds industry-standard data models, such as the USEPA Region 5 Environmental Data Model, while also offering the ability to expand or modify the data model at any point during the life of a project. HGA allows you to enter project information into the database manually, or to use the Data Transfer System to import electronic information into the database from a number of file types (XLS, TXT, MDB, …).
Borehole Log Plotting and Cross-Section Analysis
Hydro GeoAnalyst has a borehole log designer with numerous standard environmental borehole log templates that allows you to customize the presentation of borehole construction, analysis and sampled information. This may then be used in the development of cross-sections that allow you to interpret site geology, hydrogeology and layer interface information visually on-screen. These cross-sections can then be presented as part of the products of the conceptual hydrogeologic model, and used in the future development of a groundwater model.
Map Manager
Hydro GeoAnalyst has a Map Manager that can be used to combine georeferenced basemaps, vector images (DXF and SHP files), and point data (station and queried borehole data) into one mapping environment. Point data can then be interpolated using kriging, natural neighbor and inverse distance methods to generate contour plots and gridded surface for completing the conceptual description of site features.
Reporting and 3D Visualization
Hydro GeoAnalyst has a Report Editor that allows you to create and save unlimited number of dynamic report layouts, which can incorporate data values, time-series graphs, query results, borehole logs, cross-sections and 3D views. HGA 3D-Explorer allows you to render colorful, high-impact 3-dimensional views of the hydrogeologic conceptual model. These 3D images can include cross-sections, borehole logs, GIS interpolated surface grids, imported DXF and SHP files, and georeferenced basemaps.
