Overview

HEC-MetVue (Meteorological Visualization Utility Engine) is the primary gridded meteorological data processing tool for CWMS. HEC-MetVue combines observed and forecast datasets into a single dataset to serve as input to HEC-HMS and HEC-RAS models. HEC-MetVue also provides additional convenient features for the CWMS CAVI that include:

  • Auto-processing of input observed and forecast datasets
    • Filling missing data
    • Generating a combined output dataset with a uniform data interval and spatial extents
  • Visualization of basin average statistics as well as datasets animations
  • Application of value adjustments and spatial translations for sensitivity analysis and what-if scenarios

Accomplishments

  • Improved the CAVI-MetVue pre-processing:
    • Added the CAVI-MetVue Preprocessing tab with log output
    • Added visual cues to the CAVI-MetVue alternative's data nodes in the CAVI forecast simulation tree:
      • Color coded visual cues to indicate the state of processing of fully successful extracted datasets versus preprocessing of partially successful or completely unsuccessful data extracts
    • Sharpened the execution of the CAVI-MetVue pre-processing 
      • Pause until the Data Extract is complete
      • Time out and prompt user to refresh data reads when the Data Extract takes too long to complete
      • Kick off based on expected triggers (e.g. forcing a new extract and refreshing data reads for a selected alternative)
  • Developed new features that will be available in HEC-MetVue 3.2 (post CWMS 3.3.0 release):
    • Overhauled Color Scale Editor
    • New Map Layer Types for visualization
      • Raster, Wind, Terrain, and Latitude/Longitude lines
    • Overhauled Dynamic Time Window Animation
    • New Point and Polygon Sampling and Ad-hoc Plotting
    • New MetInterp Tool with both interface and scripting capabilities
      • Supporting a half dozen interpolation methods
    • New HEC-DSS output version controls for HEC-DSS 6 and HEC-DSS 7
  • Updated the User Manual Documentation for the upcoming standalone HEC-MetVue 3.2 release, as well as developed a half dozen tutorials

Field Support and Technology Transfer

  • Performed outreach to a number of districts and helped with their CWMS migration from MFP to HEC-MetVue
  • Held monthly working sessions
  • Hosted Webinars
    • Adding HEC-MetVue to an Existing CAVI Watershed
    • HEC-MetVue Image Snapshot Utility
