HEC-MetVue allows users to dynamically scan through time intervals within data loaded into a single Map Window or across multiple Map Windows. This scanning provides a means to rapidly search through time-intervals within a given dataset, allowing for analysis of storm evolution. Scanning and animation is controlled with the Dynamic Time Window Scanning Toolbar. To use Dynamic Time Window Scanning, all data within a Map Window must be spatially consistent. This means that all TINs must share the same points, or all grids must have the same projection.
Supported Layers
The Dynamic Time Window supports rendering of three layers:
Contour Band/Isohyets (TIN data) -Available only for data with irregularly spaced points.
Raster (gridded data) - Available only for data that is on regularly spaced grid points.
Polygon/Basin Averages - Available when Basin Average Mapsare specified in the Map Window.
These layers can be enabled or disabled with Map Layers settings. When drawing in the Dynamic Time Window, these layers will respect the settings specified in the Layer Settings.
Demonstration Videos
The videos below demonstrate some of the basic animation and manual data scanning capabilities within the Dynamic Time Window Scanning tool.
Single Map Window Animation - shows animation for a single Map Window
Synchronized Map Window Animation - shows the synchronized animation across multiple Map Windows. While this example shows two Map Windows, there is no limit to the number of Map Windows that may be synchronized.
