Data Selection Overview
The data selection process involves adding a new Data Source to the IDV, choosing a field to display and selecting the manner in which you wish to display it.
Working with Gridded Data
Gridded data can be the output from a numerical model or an objective analysis of observational data. Each gridded data source is comprised of a set of 2- and/or 3-D fields. Each field may have of one or more times associated with it. The IDV supports a variety of ways of visualizing gridded data. In this section we will explore some of these.
Displaying Satellite and Level III Radar Imagery
The IDV can load satellite imagery and Level III Radar Images from remote ADDE servers. Using ADDE allows the IDV to support multiple file formats. The IDV can also read in local McIDAS AREA formatted imagery.
WSR-88D Level II Data Displays
The IDV reads WSR-88D Level II data files. Each file has data for one complete volume scan of the atmosphere, including sweeps at several elevations. The IDV displays the data as sweeps and RHIs, in 2D and 3D, and as 3D isosurfaces. The IDV can be used for a general purpose Level II data viewer, and can also combine Level II data displays with other meteorological data, in 2D plots and in 3D displays in the upper atmosphere.
Saving State and Views
The IDV supports saving application state.
The IDV can display a variety of point observations
Upper Air Displays
The IDV displays upper air data. Presently the IDV displays balloon soundings (RAOBs) as a skew-T log-p diagram, and with a wind barb staff and a table of aerological values.
The IDV supports a variety of aircraft track data and displays.
GIS and Miscellaneous Displays
This section covers GIS data (DEM, WMS, Shapefiles) and the drawing tool.
NOAA Profiler Network Winds
The IDV can display winds from the NOAA Profiler Network in time-height plots at a station, and as multi-station plots wind barbs at single heights or at multiple heights in the IDV 3D display.
