Once all your GCP data is imported, click “Upload & Process.” As your data is processed into the desired deliverables, Skyward Mapping & Modeling, powered by Pix4D, will automatically detect the GCPs and apply the data you’ve uploaded. If necessary, you can swap Easting and Northing coordinates, or return one step and select a new GCP file. prj file to your Skyward project.Īfter uploading these files, you can review the GCP information. This will involve visiting epsg.io, downloading a projection file, and uploading the. Next, you’ll need to follow the given directions to identify the coordinate system you’re using.

Skyward provides a specific file format, and you can download a sample CSV file containing the supported format. Then upload a CSV file containing your GCP data. When selecting your processing type, click “Add GCPs.” To be automatically detected by Skyward Mapping & Modeling, the GCP targets will need to be square, diagonal, or Propeller Aeropoints. How do GCPs work in Skyward Mapping & Modeling, powered by Pix4D?įirst of all, you’ll need to capture a dataset which includes GCPs. While the engine processes the drone data into maps and models, it will integrate the GCP data, anchoring the map to precise location data for a more authentic representation of its precise real-world location. As part of the project creation process, the user will have the option to upload the surveyed location data as a CSV file. As the drone captures overlapping images of the area, the ground control point targets are included.Īfter the mission is complete, the survey dataset is uploaded to a photogrammetry engine like Pix4D. The drone then flies a survey mission of the area. Several of these targets are strategically laid throughout the area to be surveyed. Using traditional surveying equipment, a worker documents the exact location of the center of the GCP target in the real world. For those that don’t know, ground control points are physical targets laid out on the ground during a drone survey.
Most experienced drone mappers and surveyors will already be familiar with ground control points. Let’s take a deeper dive and see how it works. And with the power of Pix4D integrated within Skyward, you can add GCP information to your dataset without leaving the Skyward platform. This promotes detailed planning and quality assurance for your data deliverables.
Now you can improve the absolute accuracy of your 2D and 3D digital representations relative to their location in the real world. Now, we’re excited to announce another capability for our mapping and modeling solution: automatic ground control point (GCP) detection. Then we added volume measurements to bring even more value to companies that need to calculate cut and fill quantities. We initially announced a powerful set of 3D modeling and 2D mapping features, including area and elevation measurements. Skyward Mapping & Modeling, powered by Pix4D, has gotten off to a great start.
