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
