ROCK Planimetrics from High-Resolution Orthophoto
Mar 03, 2023
This dataset demonstrates the incredible flexibility of ROCK Pro Services. We executed a complete ROCK Planimetrics deliverable using only a high-resolution orthophoto as the source. Captured with a lightweight and cost-effective DJI Mavic 3 Enterprise (M3E) drone, this project proves you don't always need LiDAR to produce high-quality, detailed linework for site plans and as-built maps.
Mission Overview
- Platform: Photogrammetry survey with a DJI M3E
- Data Source: High-Resolution Orthophoto
- Area Scanned: 22 Acres
- Deliverables: Comprehensive 2D ROCK Planimetrics
This project highlights a powerful workflow for professionals who specialize in photogrammetry but need access to professional-grade drafting and feature extraction services.
Coverage & Context
The project covers a 22-acre commercial and recreational area. Using the crisp detail from the orthophoto, our team of expert GIS analysts meticulously digitized all visible features. This includes building footprints, pavement edges, sidewalks, curb lines, parking stripes, vegetation lines, and more. The clarity of the M3E imagery was sufficient to produce a clean, accurate, and layered CAD file ready for immediate use.
Dataset Metadata
- Total Acreage: 22 Acres
- Coordinate System (Horizontal): NAD83(2011) / UTM zone 16N
- Data Type: 2D Planimetric Linework (from Orthophoto)
This dataset is delivered with standard coordinate systems, ensuring it can be easily integrated into any existing GIS or CAD project environment.
Performance Highlights
- LiDAR-Free Planimetrics: This project proves the power of our planimetric service on its own. We can extract detailed features from any high-quality aerial image, expanding access to professional deliverables.
- Cost-Effective Data Capture: Utilizing a photogrammetry-focused drone like the DJI M3E lowers the barrier to entry for collecting project data, making this an accessible workflow for a wide range of service providers.
- Expert Human Extraction: While the source is 2D, the extraction is performed by our professional drafting team, ensuring that linework is clean, correctly layered, and adheres to industry standards for quality.
Applications
This workflow is perfectly suited for:
- Preliminary Site Layouts & Conceptual Designs
- Asset and Inventory Mapping for Facilities Management
- Creating 2D Basemaps for Zoning and Permitting Applications
- Projects where vertical elevation data (topography) is not required.
- Updating existing surveys with new visible features.
Key Takeaways
- ROCK Planimetrics is data-agnostic: Whether you have a LiDAR point cloud or a high-resolution orthophoto, our Pro Services team can create a premium deliverable.
- Unlock the value of your existing drone: Turn your photogrammetry flights into professional planimetric maps without investing in new hardware or software.
- Quality linework is the deliverable: Even from a 2D image, the final product is a professionally drafted, layered, and accurate representation of the site.
