Transforming data into decisions

Data Management: Data serves as the cornerstone for an environmental project. Our experts manage and apply data to scientific and engineering challenges and will treat your data as one of your most valuable strategic assets. READ MORE

• Expertise in industry data management systems, including Microsoft Access® SQL Server®, ESdat Environmental Data Management System™ and Earthsoft EQuIS™
• Mobile data collection tools that are integrated with our data management systems to help guide projects in real-time from the field (see smart data proj desc link at bottom…)
• Data management plans that help define team member roles and outline clear Data Quality Objectives (DQO’s) that can mean the difference between success and failure for a project
• Standard Operating Procedures that foster efficient data management and retrieval
• Automated cleaning and compilation of disparate data from multiple sources using Python Programming

 

Data Analysis and Statistics: Terraphase uses a wide array of tools to perform data analysis to meet project objectives. We transform environmental data into work products that support risk management decisions and guide investigations. READ MORE

• EPA’s ProUCL for confidence levels, statistical pattern recognition and trend detections
• Python programming tools such as pandas and NumPy for processing and data reduction of time series data, such as well transducer readings
• Automated exploratory data analysis, statistics, and data mining using Python programming and open source libraries such as Orange, pandas, and NumPy
• Multivariate analyses and machine learning studies of complex datasets, utilizing methods such as k-means clustering and principal component analysis (PCA) with Python libraries such as Scikit-learn
• Geochemist’s Workbench (GWB) for analyzing and visualizing geochemical data
• Contaminant forensics and fingerprinting
• Aqtesolv for hydraulic test analysis and visualization.
• Geostatistical modeling such as interpolating isoconcentation contours or groundwater elevation contours, cluster and hot-spot analysis, and spatial outlier detection.

 

Data Visualization: Terraphase excels at simplifying complex data through thoughtful data visualization in two, three and four dimensions. READ MORE

• Integrated solutions that visualize data directly from the source database
• ArcGIS Online (AGOL) web dashboards that make spatial and chemical data available to all project team members
• Database-driven statistical charts, maps, and graphs
• Data visualization using libraries such as Matplotlib, Seaborn, and Bokeh
• Web-based interactive data visualizations
• Volumetric contaminant plume and geologic mapping using Ctech EVS and EnterVol

 

Geographic Information Systems (GIS): Our extensive experience utilizing geospatial data enables us to gain deeper insights about contaminated sites. Our track record with ESRI’s GIS Software platform make us a trusted Business Partner capable of deploying custom ESRI platform solutions for our private and public clients. READ MORE

GIS mapping tasks range from creating figures for reports or presentations, displaying model outputs, and posting web‐based interactive maps online. In addition, we automate desktop tasks using Python and ESRI Model Builder and can build mobile GIS applications for field mapping and data collection needs. We offer:

• Acquisition, development, and management of spatial data including geodatabase design
• Spatial modeling and data interpolation
• Spatial analysis including area weighting, proximity calculations, and volume estimations
• Mapping of historic and existing site features with sampling data to reveal contaminant sources
• ArcGIS Online (AGOL) mapping for efficient data access and exploration
• Web-based story maps that convey complex geospatial relationships through imagery, data visualization, and text
• GIS asset management applications, custom solution development, deployment services and needs assessments

 

Drone Aerial Photography: Drones, or “unmanned aerial vehicles” commonly referred to as UAVs, allow for the acquisition of data in remote or hazardous areas that are difficult to reach and can expedite data acquisition needs. READ MORE

With their ability to cover large land areas quickly, coupled with high-quality cameras and sensors, drones can measure, transmit, and reveal insights not easily obtained otherwise for environmental analysis or compliance documentation. Drones obtain high-resolution, low-altitude photography to produce accurate high-resolution topographic maps and 3D photorealistic models via photogrammetry. Our drone services include the following:

• FAA Part 107 licensed drone pilots
• Ortho-imagery
• Elevation models
• Infrared imagery
• Bird’s eye view of construction sites to for real-time asset and material management and improved worksite safety/oversight
• Real time photodocumentary of site conditions
• 3D models and volumetric calculations by combining aerial images with advanced software capabilities

 

Computer Aided Drafting and Design (CAD): Terraphase employs AutoCAD Civil 3D software to plan, design, produce, and manage projects using 3D design modeling. READ MORE

• Surface generation, a powerful tool to model site features such as site topography. Data in the form of points, breaklines, contours, and boundaries can be added to a surface, and CAD has the ability to interpolate areas that are in between data to produce a continuous surface.
• Grading projections that can be created by configuring settings and establishing criteria. Grading criteria include the grading site, grading group, grading footprint, and grading target.
• Earthwork quantities (cut and fill volumes) that can be calculated by comparing two surfaces to one another. Calculations can be tabulated to summarize and present data in an organized manner.
• Alignments that can be produced as a combination of lines, curves, and spirals, and can represent profile locations, road centerlines, or pipe networks.
• Profiles that show surface elevations along alignments and are helpful in visualizing the terrain. Profiles of multiple surfaces can be displayed on a single grid.
