Research: Terrestrial based data capture

Who we are

The objective of this team is to develop solutions that enhance and automate the data collection process using ground-based and electronic data capture. This includes expanding the data collection capabilities of field surveyors, use of terrestrial-based data capture technology and electronic data sources already present but of which limited or no use is made. We are currently undertaking two projects an a piece of exploratory research to identify possible electronic data sources.

Pointing devices

This research investigates the use of pointing devices to aid the collection of attribute data for OS MasterMap® features. Ideally, a pointing device comprises a combination of GPS, digital compass, inclinometer and some form of mobile computer. The concept demonstrator will be implemented on a personal digital assistant (PDA) equipped with a GPS receiver and an electronic compass. The Real Time Kinematic (RTK) GPS system may be used to improve positional accuracy and it is also possible that the application will be developed using wearable computing.

Augmented reality

Augmented reality (AR) enables graphics, audio and other sense enhancements to be superimposed over a real-world environment in real time, thus augmenting the user's perception with his/her surroundings. The project will examine the use of AR to aid the data collection methods of our surveyors. The concept demonstrator will be implemented on a laptop or tablet PC, as this will allow portability and processing power. RTK GPS system may be used to improve positional accuracy.

Electronic data sources

Ordnance Survey already makes use of some electronic data sources such as the Postal Address File and builders' plans. However, there is significant potential in exploiting many other sources, either for data collection or change intelligence purposes. At this stage a small piece of exploratory research is being conducted to identify possible data sources and the manner in which they could be used.
