GIS & REMOTE SENSING MODELING
ArcGIS Database Development Services
ArcGIS is a user friendly geographic information system software platform developed by the Environmental Systems Research Institute (ESRI) which is utilized by businesses, government agencies and public/private water utilities to keep track of valuable assets located across wide spatial areas. The ArcGIS platform has thousands of built in functions to spatially analyze assets and spatial attributes, providing valuable data to help decision makers make informed decisions about how to invest, maintain and manage capital infrastructure. As a water resources firm, WRMA specializes in ArcGIS database development for water and sewer infrastructure and GIS based water resources modeling. WRMA's GIS development team can build custom GIS based solutions for private or municipal water utilities and provide water resources engineering services including hydrologic & hydraulic modeling, environmental assessment and asset mapping.
GIS Capabilities in Asset Management
For today's asset managers, a GIS database is indispensible. The ability to spatially locate and analyze in real time, water and sewer assets within a service area, provides engineers, managers and maintenance personnel with an advanced spatial awareness and "big-picture" understanding of the status and condition of their water or sewer system. Spatial awareness combined with real-time data analytics means that utility managers can allocate capital and O&M resources efficiently and effectively from the comfort of their office or in the field on a mobile device. In the long term, GIS databases can be continually updated as new infrastructure is built and as existing infrastructure is maintained, creating a data trail of what work was completed, when and where. WRMA's engineering team has assisted public utilities in the design and implementation of GIS based data management systems and can provide reliable service throughout the lifetime of the system such as providing periodic system updates, to creating user-specified custom built modules to perform specific data analysis and management functions.
ArcHydro Floodplain Modeling for D-FIRM Development
The Federal Emergency Management Association (FEMA) created the National Flood Insurance Program (NFIP) in 1968 to protect property owners from catastrophic flooding, in particular, for properties in the vicinity of major waterways within the boundary of the 100-year flood stage elevation or "Base Flood Elevation (BFE)". WRMA's hydraulic engineers are certified in floodplain management by the American Society of Flood Plain Managers (ASFPM) and specialize in floodplain modeling using GIS based modules such as ArcHydro, to delineate floodplains for the purpose of developing Digital Flood Insurance Rate Maps (D-FIRM's). WRMA is experienced and highly specialized in floodplain modeling and has assisted with the implementation of the Arc Hydro Enhanced Database (AHED) development and application of MAPMOD methodology for the digital updates of the C-4 and C-6 Miami-Dade County FEMA FIRM maps.
Digital Elevation Model Development
Digital Elevation Models (DEM's) or Digital Terrain Models (DTM's) are three dimensional elevation models built in GIS or CAD based software platforms for the purpose of analyzing existing topography for a myriad of civil engineering, environmental and water resources applications. WRMA engineers are experienced in the development of DEM's for the purpose of analyzing how topography affects the hydrologic and hydraulic performance of natural or man-made channels including rivers, streams, stormwater management and sanitary sewer systems. Additionally, WRMA often builds DEM's when conducting slope and erosion analysis studies. WRMA has built DEM models from various data sources including topological surveys, satellites and aerial light detection and ranging (LiDAR) data. One of the benefits of building a detailed DEM is that it provides WRMA's design engineers with an enhanced understanding of environmental awareness while also providing the client with a 3-D visual representation of how a proposed facility might appear when completed.
Watershed Image Analysis
WRMA Watershed Image Analysis services using GIS and remote sensing include:
- GIS database development for H&H modeling, environmental assessment and mapping.
- LiDAR, RADAR , Multi and Hyper-Spectral remote sensing data rectification, classification, and image analysis for water resources engineering.
WRMA image analysis is a highly specialized field that entails the application of state-of-the-art image processing software for the classification of various sources of airborne and/or satellite-based imaging data used in watershed hydrologic and environmental assessments. Using advanced remote sensing (RS) techniques with multi and hyper-spectral, color infrared, LiDAR, and RADAR image data, WRMA's engineering team can provide water quality modeling, monitoring, and flood damage forecasting for surface water ecosystems. A WRMA water quality assessment may for example utilize hyper-spectral imagery for measuring and mapping the concentrations of suspended chlorophyll (Chl), suspended minerals (SM), dissolved organic carbon (DOC), and turbidity in coastal rivers and estuaries. This 21st century approach to water quality monitoring can enable WRMA's clients to detect and monitor early toxic algae blooms responsible for oxygen depletion, fish kills, and human health hazards in waterways.
