AGI Northern Ireland

AGI Northern Ireland December Webinar

AGI Northern Ireland are delighted to announce their Webinar Thursday 3 December 12:30-14:00 focusing on remote sensing technologies and application of spatial intelligence in decision making

This webinar is aimed at anyone with an interest in Geographic Information and Remote Sensing, plus beneficial for those interested in Early Careers Network.

Rebekah Megarity and Naomi Wharton are recent Ulster University MSc graduates now working at the Ordnance Survey for N. Ireland (OSNI) and will be presenting their dissertation projects. Ryan Johnston, formerly a Senior Technologist at Connected Places Catapult, is a researcher and PhD candidate at Ulster University and will be giving a presentation on digital twins.

Timings (20 min presentations + 5 minutes for Q&A)

12.30-12.35 Rico Santiago (AGI NI Chair)

12.35-13.00 Rebekah Megarity (Mapping and Charting Officer, OSNI)
Evaluating the effectiveness of data fusion in producing a high-resolution multispectral land cover map of NI (Ulster University, MSc Dissertation)

Combining OSNI orthoimagery (40cm) with Sentinel-2 imagery (10 bands), using data fusion techniques, to produce a high-resolution multispectral image. This was used to produce a land cover map of Newcastle, NI, with 12 land cover classes. The project employed an object and pixel-based approach to create a land cover map with an accuracy of 87% and produced better results than its parent imageries.

13.00-13.25 Naomi Wharton (Mapping and Charting Officer, OSNI)
Modelling the relationship between satellite measurements of night-time light and socio-economic indicators of deprivation, population and wealth in India (Ulster University, MSc Dissertation)

At night, anthropogenic sources of light illuminate the Earth’s surface, known academically as night-time lights (NTL), they are a measure of light brightness that can be observed from space. The NTL data in this thesis was captured from the Visible Infrared Imaging Radiometer Suite Day/Night band. The imagery was extracted from Google Earth Engine using JavaScript and Python scripts to run a chain of processing commands including spatial calculations and exportation of high resolution imagery. NTL helped detect micro-scale activities such as slum development, rural-to-urban migration and highlighted the sustainable switch from sodium vapour bulbs to LEDs in Indian city centres. Results showed the strongest correlation with NTL measurements were population (R2 = 0.82) and electricity generation (R2 = 0.73).

13.25- 13.50 Ryan Johnston (Researcher, Ulster University)
Mapping a route to Digital Twins & Serious Games

A short look at the rise of digital twins, how they can support complex decision making, and the critical role Spatial Intelligence has in making them work. Based on Ryans previous experience at Connected Places Catapult, Self-Driving Cars, and future work highlighting the new role of digital twins to support Net Zero developments.
