10 steps to improving High Accuracy GIS Data Capture

In the fast-evolving geospatial world, ensuring high accuracy GIS (Geographic Information Systems) data capture is crucial. Precision in spatial data impacts decision-making across various sectors, including urban planning, environmental monitoring, and asset management. At MGISS, we understand the importance of high accuracy GIS data capture and have partnered with industry leaders like Leica GeoSystems, Eos Positioning Systems, and ESRI to provide cutting-edge solutions.

Here are 10 steps to enhance the accuracy of your GIS data capture:

1. Understand Your Accuracy Requirements 

Before embarking on any data capture project, it’s essential to define the level of accuracy required. Different projects will necessitate different levels of precision. Understanding these requirements will guide the choice of equipment and methodologies to use. 

2. Select the Right Equipment 

High-accuracy GIS data capture begins with the right tools. Equipment from our partners, Eos Positioning Systems and Leica GeoSystems, provides the precision and reliability needed for high accuracy data capture. Eos Positioning Systems’ Skadi & Arrow Series® GNSS receivers and Leica GeoSystems’ Zeno range of GNSS receivers are tailored for integrating with GIS software offer centimetre-level accuracy, ensuring your project requirements are met with the highest standards. 

3. Utilise High-Quality Base Stations 

Using high-quality base stations can significantly improve the accuracy of your GNSS measurements. Leica’s SmartNet, a network of continuously operating reference stations, provides real-time corrections, enhancing positional accuracy. 

4. Employ Differential GNSS (DGNSS) 

Differential GNSS techniques, such as Real-Time Kinematic (RTK), correct errors in GNSS signals, allowing for higher accuracy. Tools from Leica GeoSystems (SmartNet) and Eos Positioning Systems (Atlas®) support these techniques, ensuring precise GIS data capture. 

5. Integrate Advanced Software Solutions 

Software plays a critical role in processing and analysing GIS data. ESRI’s ArcGIS platform offers robust tools for managing, analysing, and visualising spatial data. Integration with high-accuracy GNSS devices ensures that the captured data is both accurate and useful. 

6. Conduct Regular Calibration and Maintenance 

Regular calibration and maintenance of your equipment are essential to ensure ongoing accuracy. Follow the manufacturer’s guidelines for calibration and perform routine checks to keep your devices in optimal condition. 

7. Train Your Team 

Investing in high-accuracy equipment is only beneficial if your team knows how to use it properly. Provide comprehensive training on the use of GNSS receivers, software applications, and best practices in GIS data capture. 

8. Implement Quality Control Measures 

Establishing rigorous quality control procedures can help in identifying and correcting errors in your data. Regularly review and validate the captured data against known benchmarks to ensure its accuracy. 

9. Utilise Real-Time Correction Services 

Real-time correction services, like those offered by Leica’s SmartNet, can provide immediate improvements to the accuracy of your data. These services correct satellite signal errors in real-time, ensuring high precision in your measurements. 

10. Set Up Averaging GNSS Positions within ArcGIS Field Maps 

Using ArcGIS Field Maps, you can set up averaging of GNSS positions to improve data accuracy. This involves capturing multiple GNSS positions over a period of time and calculating an average position, reducing the impact of any single erroneous reading. This method enhances the reliability of the collected data, ensuring higher precision. 

High accuracy in GIS data capture is attainable with the right combination of equipment, software, and practices. At MGISS, we are committed to providing the best solutions from industry leaders like Leica GeoSystems, Eos Positioning Systems, and ESRI. By following these ten steps, you can enhance the accuracy of your spatial data, leading to better decision-making and more successful projects.
