Curtain

Vertical imagery aligned under terrain for visualizing data from ground penetrating radar.

Raw Variables

The following is an example of the Sites Tool’s Tool Tab configuration:

{
    "withCredentials": false
}

• withCredentials: An array of objects required to add sites.

Configuring Features

To setup curtains, add objects of type “radargram” to a LineString feature’s properties.images array and enable the Viewer Panel.

• mode: Any string to show in a dropdown in the Curtain Tool to identify and switch between radargrams in case there are many.
• topElev: Top elevation in meters that correspond to the top pixel of the radargram image. Radargrams should be generated to be terrain aligned.
• depth: Depth of radargram image in meters.
• length: Width of radargram image in meters. May use LineString geometry’s length.
