Annual Conference 2025
GeoViz Professional Development Day Workshops
Wednesday 3rd September 2025
Sustainable Transport and
the GeoViz Toolkit
Clare Seldon, Freelance Cartographic Designer
​
Using the toolkit for prompts, we will explore some open source cycle and bus stop data and convert into QGIS, filtering accordingly to make a usable map. We will then convert to Adobe to style the map using Illustrator’s font, symbol and global graphic and colour swatch styles using the Toolkit for inspiration.
Note: Software requirements will be sent to delegates prior to the workshop.
​
Clare Seldon is an accomplished cartographic designer and lecturer with over 25 years of experience specialising in transport and event mapping. She holds a BSc in Cartography from Oxford Brookes University and has been a Chartered Geographer with the Royal Geographical Society since 2014. She has received several prestigious accolades, including honours in the British Cartographic Society (BCS) Awards, the Wallis Award in 2014, and a feature in Atlas of Design, Volume 7 (2024). Clare has served on the BCS Council since 2021. In this role, she leads social media outreach initiatives and advocates for the ongoing advancement of cartographic design education in step with emerging technologies.
Land Cover to Habitat Classification:
the possibilities and limitations.
Chris Burnett, Chief Product Officer, Map Impact
Habitat mapping is required for an increasing number of use cases, from Environmental Impact Assessments, to mapping of Natural Capital, however, challenges exist in mapping habitats due to lack of available data, and lack of granularity. This workshop will explore how land cover mapping can be utilised to serve an alternative purpose by mapping habitat types.
​
Chris Burnett has worked on many land and sea classification projects across the world, including a 2-year project to map the habitats of Abu Dhabi Emirate in detail from satellite imagery and ecologist’s ground truthing data. More recently he has utilised existing land cover mapping sources to help shape and create Map Impact’s BiodiversityView product.
3D modelling: How to create a
geological profile
Led by British Geological Survey - Helen Burke, 3D geological modeller & surveyor, Steve Thorpe, Geospatial data specialist & lead driller​​
Have you ever wondered how to draw cross-sectional geological profiles to help understand the subsurface? This short workshop will show you everything you need to know from choosing the right profile, identifying the key geological and mapping features, building the subsurface geological information from known observation points such as boreholes, and creating a well-thought out and balanced cross-section output. The staff from the British Geological Survey will be on-hand to guide you through the process. They will help with any questions (geological or otherwise) and advise on choice of software to help design and draw your cross-sections.
​
Helen Burke joined BGS 25 years ago in the Enquiries department, fielding questions on all aspects of geology to experts in BGS. This role gave insight into the breadth of knowledge and experience of our BGS colleagues. Helen moved into geological surveying and 3D modelling and then joined the BGS Products team, providing experience in primary geological surveying in the field through to interpreting data in a 3D modelling environment and the publication process to make data available for our user community.
​
Steve Thorpe started at BGS 20 years ago as an Assistant Scientific Officer working on a broad variety of projects and learning about BGS baseline data. This led into 3D modelling where Steve learned many geological skills such as drawing cross-sections from borehole and map data. Steve hopes to bring this knowledge to the workshop and guide people through this process, considering all the benefits and limitations of the data.
Urban Land Use Mapping:
The cartographic challenge
Dr Seppe Cassettari, former BCS President
​
This workshop will explore the issues of creating effective urban land use maps with data attributed to large scale geodatabases. It will briefly look at the range and types of land use classification adopted over the past 50 years, the difference between land use and land cover and the problem of how to represent 3D land use in a 2D form. The workshop will use a case study area in London to demonstrate the need for creative cartographic solutions to complex hierarchical land use classifications.
​
Seppe Cassettari worked with land classification data for much of his 40-year career. He was involved in early urban green space and telecom land use classification and developed the hierarchical UKMap land use model in the early 2000’s. His career spanned academia, the military and more recently as owner of The GeoInformation Group, an independent geospatial data publisher. Although formally retired he is still active in the geospatial community.
