Reference geometry demo This form demonstrates using existing geometry as context for capturing new shapes or traces. The question below lets you capture a new geoshape to the places Entity List and shows previously-captured geoshapes in the Entity List as reference. Capture geoshape Give a name to the shape you just captured. Next, you'll see a geotrace question in a repeat. As you add traces, they will be shown as reference for the next traces captured.
