our services

Cherokee Imaging understands engineers design projects in CAD and GIS platforms, not on web viewer links of point clouds. We provide a host of imaging services to satisfy your specific project requirements, in standard design format deliverables, and in the projection of your choosing.

Topographic models

LiDAR data is increasingly utilized in land management, civil engineering, and construction to provide an accurate surface model at all project phases. LiDAR's unique ability to penetrate dense vegetation and canopies enable highly accurate surface modeling where other methods might contain inaccuracies or data voids. This enables us to build an accurate Digital Elevation Model (DEM), yielding a design-ready bare earth model to include contour lines at intervals ranging from 6" to 100'. Breaklines are included to further increase the contour accuracy. In addition to bare earth models, we can also include building, vegetation, roads, water, bridges, and transmission classification in ASPRS schema. Hydro-flattened DEMs are also available. Finally, an accuracy report is included with every survey to verify LiDAR data against known surveyed ground points.

Base Deliverables:

Ground Classified laz file (Bare Earth)
SHP file vector data (contours/breaklines)
DXF, DWG vector data (contours/breaklines)
Grid export in SHP and/or DWG/DXF format
TIN surface in ASCII or LandXML format
DEM in TIF format
LiDAR Accuracy Report (RMSEz)

Powerline management

Cherokee Imaging can provide modeling of transmission lines and corridors for direct import into PLS CADD (Power Line Systems Computer-Aided Design and Drafting) software. We’ll take your specific Feature Code List and deliver the data in LAS, ASCII XYZ, DXF and .BAK files

Accurate Terrain Mapping: We can provide highly accurate terrain data and planimetrics, allowing for precise modeling of the landscape through which transmission lines will run. This includes capturing the elevation changes, vegetation, buildings, and other features that may affect the placement and design of the transmission lines.

Vegetation Management: LiDAR can detect vegetation density and encroachments along the transmission corridor. This information is crucial for assessing clearance requirements to prevent vegetation interference with the transmission lines.

Structural Analysis: LiDAR data can also aid in assessing the structural integrity of existing infrastructure such as towers, poles, and other support structures along the transmission line route. This information is important for evaluating the suitability of existing infrastructure for supporting the transmission lines or identifying areas that may require reinforcement or replacement.

3D Visualization: Our PLS CADD models provide accurate 3D visualizations of the transmission line corridor. This allows engineers and designers to better understand the terrain and environmental conditions and make informed decisions during the design process.

Efficient Surveying: Drone LiDAR technology enables rapid & dense data collection over hundreds of acres per day, making it a cost-effective solution for surveying transmission line routes compared to traditional methods. Minimize your field crew’s time on site and the associated hazards of proximity to energized structures!

2d/3d planimetrics

Deliverable Options:

Classified las/laz file
DXF/DWG linework
SHP linework

Planimetric maps show man-made and natural objects outlined with 2D or 3D features. This can include parking lots, buildings, utilities, sidewalks, fences, roads, water features, vegetation and building footprints. We can provide 2D planimetrics from rectified orthomosaic imagery or 3D planimetrics from LiDAR point cloud data. Deliverables will be in the formats below and custom symbology and feature coding is also available.

volumetrics

Cherokee Imaging can provide highly accurate stockpile volumes to assist project managers with earth movement progress, mining yields, and site change management. Volume measurements are typically accurate within 1-2% of traditional ground-based laser measurements. Density calculations are also available for various materials involved. These measurements combined with same-week delivery are invaluable tools to manage site status and third party progress verification. Deliverables can be tailored to your project budget ranging from a report-only format or include a full 3D dataset.

orthomosaics

Our imaging platform utilizes a calibrated 20MP mechanical shutter camera to collect multiple high-resolution images to be combined into a single image of the project area. This image is orthorectified to correct for lens distortions and apparent changes in the position of ground objects caused by the sensor viewing angle and ground terrain. Each pixel is accurately georeferenced utilizing Aero-Triangulation methods using known ground control points. This single nadir image is suitable for taking ground measurements and overlaying with other layers in a variety of mapping applications. Or, this image can simply provide a highly detailed and up-to-date capture of the project area vs a standard GoogleEarth image. Imagery will be delivered in standard uncompressed or compressed raster formats (GeoTiff, PNG, jp2, MrSID, ECW)
