UNLOCKING THE ADVANTAGES OF DIGITAL SURFACE MODELS (DSMs)

At SkyMap Technologies, we deliver high-resolution Digital Surface Models (DSMs) that capture the true shape of the earth’s surface — including every building, tree, and structure above ground.
Our DSMs provide a powerful visual and analytical foundation for engineers, surveyors, developers, and planners to better understand surface elevations, line-of-sight, drainage, and site dynamics with unparalleled clarity.

Unlike Digital Terrain Models (DTMs) that depict bare earth, Digital Surface Models show everything visible on the surface — vegetation, buildings, utilities, and terrain features.
SkyMap’s DSMs offer a true-to-life 3D representation of existing conditions, allowing teams to visualize, measure, and analyze surface structures with precision.

Applications include:

• Urban design and infrastructure planning
   
• Vegetation and canopy modeling
   
• Line-of-sight and solar exposure studies
   
• Drainage and watershed analysis
   
• Pre-design and cut/fill modeling
   

Whether you’re planning new development or assessing existing conditions, SkyMap’s DSMs give you the clarity needed to make smarter, data-driven decisions.

SkyMap produces DSMs using survey-grade LiDAR and photogrammetry, combined with GNSS ground control to ensure vertical and horizontal accuracy within centimeters.
Each dataset is built from dense, georeferenced point clouds and validated through a rigorous quality control process.

Our workflow includes:

• Drone-based LiDAR and high-resolution imaging
   
• Automated point classification and elevation modeling
   
• Ground control verification and field checks
   
• Post-processing for surface consistency and precision
   

The result is a highly accurate digital elevation surface that engineers and planners can depend on for modeling, analysis, and design.

SkyMap’s drone-based mapping workflows enable large areas to be captured in a single flight — providing surface data quickly and efficiently compared to traditional survey methods.

Key advantages include:

• Reduced field time and faster project delivery
   
• Comprehensive coverage of complex terrain and structures
   
• Seamless integration with DTMs, orthomosaics, and 3D models
   
• Compatible deliverables for CAD, GIS, and BIM platforms
   

Whether for progress monitoring, site evaluation, or engineering design, SkyMap’s DSM solutions deliver more data in less time — without sacrificing accuracy.

With over 20 years of combined experience in surveying, land development, and construction, SkyMap Technologies understands the value of dependable surface data.
We combine industry-leading LiDAR and photogrammetry tools with real-world expertise to ensure every DSM meets professional standards for precision and usability.

Our team delivers data that integrates directly into your design and analysis workflows, ensuring you receive accurate, consistent, and actionable surface models every time.

SkyMap provides complete Digital Surface Model deliverables, tailored to your project specifications:

• High-resolution DSMs and DEMs
   
• Contour maps and elevation shading
   
• Combined DSM/DTM surface comparison
   
• Solar, visibility, and terrain analysis
   
• Volume and cut/fill reporting
   
• CAD-, GIS-, and BIM-compatible data formats (GeoTIFF, DXF, SHP, LAS)
   

Each deliverable is accurately aligned, fully georeferenced, and quality-verified, giving your team reliable data from the start of the project through final design.
