### NVIZ - What's Here

The What's Here panel operates like the GRASS program d.what.rast, you use the mouse to mark spots on the surface that you would like more information about. After clicking on the surface, data prints to the text box in the panel. First, the name of the surface clicked on is printed then the geographical coordinates. Next, elevation is bi-linearly interpolated from the current polygon resolution and this is printed (setting the resolution to 1 will produce the most accurate elevation). xy distance from previous and xyz distance from previous are straight line distances, whereas distance along surface and distance along exag surface are computed as the length of a path draped across the surface. Each time you select a point, a marker is drawn on the surface at the point selected with a line connecting it to the previous point. To stop selecting points toggle the What's here? button.
