Lake County, Colorado — 5ft contour interval
Client: Professional Land Surveyor
This project in Lake County, Colorado included steep, heavily forested terrain that would have required weeks of field collection. After field verification, our data was integrated into the official survey.

ContourLabs transforms LiDAR into CAD-ready topographic maps. Fast, affordable, and designed for early-stage planning or to supplement field-verified survey work.
Supplement fieldwork with LiDAR-derived topography across large, steep, or difficult terrain.
Get existing terrain into your workflow faster for early grading, drainage, access, and site planning.
Understand the site before design begins with terrain data prepared for your design software.
See the shape of the land early so your concepts respond to existing slopes, drainage, and elevation.
Understand terrain, access, and site constraints before committing to expensive survey and design work.
Understand what may be possible on your property before investing in survey, design, or construction.
Use ContourLabs to plan and decide. Use a licensed surveyor to build and define boundaries.
