TopoMatters – Colorado Drone Mapping and LiDAR


Photogrammetry-based deliverables to maximize visual insights and engagement

existing conditions

Understand existing conditions and the big picture view

The digital orthophoto map is a composite mosaic of aerial images that undergo geometric correction, known as “orthorectification,” to ensure a uniform scale. This correction eliminates distortions, making the photo comparable to a map. Unlike uncorrected aerial photographs, an orthophotograph provides an accurate depiction of the Earth’s surface, accounting for topographic relief, lens distortion, and camera tilt. This accuracy enables the measurement of true distances. Widely employed in geographic information systems (GIS), orthophotographs serve as a “map-accurate” background image, facilitating precise spatial analysis and mapping activities.  The orthophoto map can also be imported and viewed in Google Earth.

Take Measurements and Track Progression

Forget the tape!  Whether your scale is in inches or hundreds of feet, takeoffs from your photo or tablet are easy when you have the data at your fingertips.

Easily Identify Changes in Elevation

Every project includes a geo-referenced digital surface model (DSM), a 3D representation of the Earth’s surface that include all objects above the ground, such as trees, buildings, and other structures.  The DSM provide detailed information about the height and location of buildings, vegetation, and other structures, enabling informed decisions about stockpile volume, land use, infrastructure development, and environmental impact assessments.

shaded relief map

Simulated 3D

The shaded relief map represents the topography of the project site in a three-dimensional way. This is done by simulating the way light and shadow would fall on the land surface, creating an illusion of depth and relief. Shaded relief maps are often used to communicate with audiences who need to understand the physical features of a landscape.

Terrain Slope Map

The slope map represents the topography of the project site using colors to illustrate slope angle of the terrain. Slope maps are like heatmaps for terrain, showing how steep or gentle an area is at each point. Here lighter colors represent flatter areas, while darker colors like red or brown signal steeper slopes. These maps are vital for planning development projects, access, construction and understanding environmental factors.

planimetric line work

Available CAD Linework

Depending on your project, linework might be the only data that you need, without the data that you don’t. Our CAD linework is professionally drafted from the drone data collected from your project site. Features that can be seen from the air can be captured in linework with incredible precision. Contour lines, spot elevations, break lines, building drip lines, edge of road/curb/sidewalk, paint striping, tree locations and more. Linework is delivered in a .dwg CAD format.

Available 3D Mesh Model

The 3D model engages your audience with perspectives derived from the photogrammetry processing by creating a mesh of millions of interconnected faces and painting each one with the color and texture from the original photos. The textured mesh is creator-friendly and delivered in an .obj file format.
