RadarLab HD
Incorporating WeatherTAP data in a GIS client

WeatherTAP's RadarLab HD RadarLab HD is a weatherTAP feature which allows the user to have interactive control over weather graphic presentation. Using RadarLab HD, the user may select from any number of radar product images such as reflectivity, velocity and echo tops.

The "Base Reflectivity (Level-II)" image is built using the higher resolution Level-II radar data. The underlying map on which the radar data and other layers are drawn can be changed to either a land/sea, terrain or satellite based image. Users can then overlay many different geographical layers on the image including county and state boundaries, city and county labels, airports, roads and even user defined custom locations.

Users also have the option of displaying many types of data layers. These include current temperatures, lightning strikes, storm tracks, surface observations, watches, warnings and advisories. Users can zoom in up to a 30 meter resolution and pan around the zoomed image by using the mouse. Animations can be created by loading up to 20 radar images. The user can single-step through animations or control the playback speed. All the overlaid layers and zooms also apply to animations.

An advanced radar filtering option is available by pressing the "Filter Radar" button. All the currently displayed layers may be automatically reloaded by selecting the "Auto Refresh" checkbox.

System Requirements
