Easily import Ground Control Points (GCPs) into your SDX-Cloud project for improved geospatial alignment. This guide walks you through setting up a GCP set, which will be automatically applied to incoming data from integrations like DJI Dock or ViDoc.
Summary
This article explains how to create a Ground Control Point (GCP) set within your SDX-Cloud project settings. GCPs improve geospatial accuracy and are automatically applied to new snapshots starting from a specified date.
Introduction
Ground Control Points (GCPs) serve as anchor coordinates that enhance geolocation accuracy for aerial or machine-collected data. In the SDX-Cloud, you can upload a CSV file of GCPs and apply it starting from a specific date for all new incoming snapshots from automated sources or manual imports in a Data Project.
Prerequisites
Project Admin Access
A project already created in SDX-Cloud
A properly formatted
.csvfile containing your GCPsKnown coordinate format (Easting, Northing, Height) and optional accuracy values
Recommended browser: Chrome, Firefox, or Edge
Step-by-Step Instructions
Explore the above interactive demo to learn how to create and import a GCP set directly in SDX-Cloud. The demo is interactive—click through each step to follow along. Alternatively follow the written guide below.
📍 Step 1: Open GCP Settings
Navigate to your project in SDX-Cloud.
Open the Project Settings menu.
Click on the Ground Control Points section.
Press the "+" icon at the top right to start a new GCP set.
📝 Step 2: Configure Metadata
Name the GCP set (required).
Add an optional description.
Set the Start Date — this determines from which day the GCPs are applied to automatically uploaded snapshots.
Enter the diagonal length in millimeters (defines GCP marker size for processing).
Click Next to continue.
📂 Step 3: Upload GCP CSV File
Select and upload your
.csvfile.Choose the appropriate delimiter (e.g., comma, semicolon).
Indicate whether the file includes a header row.
Click Next.
🔄 Step 4: Map CSV Columns
Match your CSV columns to the following required fields:
Easting (X)
Northing (Y)
Height (Z)
Horizontal Accuracy (optional)
Vertical Accuracy (optional)
Make sure all necessary mappings are correctly assigned. Once done, click Import.
✅ Completion
Once the GCP set is imported, it is active and will be automatically applied to all matching snapshots starting from the configured start date.
Common Issues or Tips
GCP sets cannot be modified after creation. If you need changes, delete the set and re-import, or contact support.
Ensure that your CSV uses a consistent coordinate system with your project settings.
The import might fail if required columns are missing or incorrectly mapped.
