LANCE shares circles, ellipses/ovals and rectangles today, with more shape types arriving for the release. The set is expanded carefully and deliberately — every extra vertex is extra airtime — so each shape stays cheap and reliable on the mesh.
Share range & bearing lines (R&B) to communicate distance, direction, standoff or coverage at a glance. Like markers and shapes, they're reconstructed as native ATAK objects on every connected client.
Shape and range objects stay on the order of tens of bytes over the air, with acknowledged delivery like markers. They're slightly heavier than a marker but still cheap — so a planned area graphic doesn't dominate the channel.
Shapes carry the full 24-bit RGB colour range, so the colour you draw is the colour your team sees. Whatever you assign in ATAK is preserved across the mesh and reconstructed faithfully on every connected client — no palette limits, no surprise substitutions.
