Elevate Your Data: Post-Processing Services & Derivative Products

At Barr Geospatial, we understand that raw LiDAR data is just the beginning. To truly harness the power of this data, we offer a comprehensive suite of post-processing services and derivative products designed to transform your raw data into actionable insights.

Digital Elevation Models (DEM)

Digital Elevation Models (DEMs) are foundational data for a variety of applications, including hydrology, urban planning, and environmental management. Our DEMs provide detailed representations of the Earth's surface, capturing the natural terrain features with high accuracy. By converting LiDAR data into DEMs, we enable you to visualize and analyze elevation changes across your area of interest, supporting tasks such as flood risk assessment, watershed management, and infrastructure development.

Digital Terrain Models (DTM)

For projects requiring an understanding of the bare earth surface, our Digital Terrain Models (DTMs) are invaluable. Unlike DEMs, DTMs remove all above-ground features such as vegetation and buildings, offering a clear view of the underlying terrain. This is particularly useful for geotechnical analysis, archaeological studies, and construction planning, where accurate terrain information is critical.

Contours

Contours are fundamental in topographic mapping, providing a simplified representation of elevation changes through lines of equal elevation. Our contour generation service transforms LiDAR data into detailed contour maps, which are essential for civil engineering, landscape architecture, and land use planning.

Slope Maps

Slope maps are crucial for assessing terrain stability, planning infrastructure, and conducting environmental impact studies. By analyzing the rate of elevation change, our slope maps highlight areas of steep slopes and gentle inclines, helping you to identify potential challenges and opportunities within your project area.

Planimetric Mapping and Classification

Planimetric maps provide detailed, two-dimensional representations of features on the Earth's surface, such as buildings, roads, and utility lines. Our planimetric mapping service extracts these features from LiDAR data with high precision, creating maps that are essential for urban planning, utility management, and transportation projects.

Tree Height Analysis

Understanding vegetation structure and height is critical for forestry management, ecological studies, and urban planning. Our suite of tree analysis service uses LiDAR data to measure the height, width, and canopy coverage of individual trees, providing detailed insights into tree species composition and health. This information supports sustainable forestry practices, wildlife habitat assessment, and green infrastructure planning. Learn more about our Forestry Management program here.

Cut and Fill Modeling

Cut and fill modeling is a key component of construction and land development projects. This service involves calculating the volume of material that needs to be excavated (cut) or added (fill) to achieve a desired landform.
