This capability is perfect for projects that require real-time data, such as construction site monitoring. With RTK-equipped drones, your data is processed as it’s collected, enabling you to make quick decisions based on highly accurate information.
PPK (Post-Processed Kinematic) Capabilities
On the opposite side, you have PPK, or Post-Processed Kinematic, which also offers high precision. Unlike RTK, which processes data in real-time, PPK allows you to gather data and process it afterward, which can be more flexible and reliable in difficult environments. This capability is especially useful in areas with poor GPS signals or when you require very high precision mapping and have more time to process data post-flight.
Use of Ground Control Points (GCPs)
Ground Control Points (GCPs) are critical for ensuring your maps are as accurate as possible. These are pre-measured points on the ground that can be used to georeference your maps accurately. Incorporating GCPs into your workflow can drastically improve the accuracy of your mapping efforts, even when using drones without advanced capabilities like RTK or PPK. They serve as a benchmark to validate your mapping data.

Issues with Image Geo-tagging
Image geo-tagging is crucial in mapping as it ensures each image can be correctly positioned within your map. However, not all drones or software handle geo-tagging seamlessly, and mismatched or missing geo-tags can create serious headaches during processing. Verifying that your drone’s camera accurately geo-tags images and integrates smoothly with your chosen software will save you time and frustration.
Potential Challenges with Software Integration
Sometimes, software integration is not as seamless as you might hope. Image format compatibility issues and discrepancies in data processing can occur if your drone’s hardware isn’t fully supported by your chosen software. Testing your workflow on a small scale before fully deploying it can help identify integration challenges early on, allowing for mid-course corrections.
