VECTOR TOOLS
STREAM's vector drawing tools let you draw points, lines and areas that sit directly on the terrain surface. Sketch them over your DEM and imagery, organize them in layers, and export the result to CAD.
Vector objects in STREAM are draped on the DEM, so a line follows the terrain and a point sits at its true elevation. That keeps drawings consistent with the surface they describe.
Layers keep the drawing organized, and snapping keeps it precise.
Draw vector points, lines and areas that sit on the terrain, organized into named layers.
Snap to existing features so drawings connect cleanly and stay precise.
Triangulate selected points, lines and areas into a TIN surface, or trace a contour as an area.
Send your vector layers to DXF for CAD, keeping the layer structure.
Point, line or area. Left click adds a vertex, double click or right click finishes, Esc cancels — and Ctrl+Z undoes across drawing, measurement and terrain edits alike.
Vertices land on the terrain and take their elevation from it, so the geometry is three-dimensional from the first click.
As soon as a geometry is active its own tab appears with every command that applies to it — drape to terrain, simplify, offset, triangulate, follow an elevation.
Give each vector a layer, colour and visibility so the drawing stays readable as it grows.
Send the vectors to DXF for CAD keeping the layer structure, or to CSV when you need the coordinates as a table.
Yes. Points, lines and areas are draped on the DEM, so they sit at true elevation and follow the surface.
Yes. STREAM exports vector layers to DXF, keeping the layer structure for CAD.
Yes. STREAM triangulates selected points, lines and areas into a TIN surface, and can trace a contour as an area.
