Ranking among the world\u2019s top biodiversity hotspots, the forest also plays a vital role in climate regulation. Once spanning more than 350 million acres, the Atlantic Forest has lost ~88% of its original vegetation to human activity, leaving it one of the most endangered biomes on the planet. Although much of this deforestation occurred over the last century, the process began with the colonisation of the region by the Spanish and Portuguese during the 16th\u201319th centuries, with early colonial settlement patterns, commodity frontiers and and key transport routes influencing the spatial distribution of deforestation in the region.\r\n\r\nRecent studies have begun to recognise contemporary Indigenous territories as critical spaces for forest conservation, but less attention has been paid to the historical impacts of colonial-era Indigenous resistance on present-day deforestation patterns. To address this gap, we first generated forest cover maps for the Atlantic Forest from declassified CIA satellite imagery (c. 1965) and collated a database of geolocated sites of historically documented Indigenous resistance (c. 1500-1800) events from national archives. Next, we calculated the impact of Indigenous resistance on probable colonial routes through the forest using a least cost path based approach that incorporated topography, river direction and flow speed, the presence of rapids and waterfalls, and the cost of portage. Finally, distances from both sites of Indigenous resistance and disrupted colonial routes were incorporated into a an explanatory spatial Random Forest model as predictors, alongside other key anthropogenic and environmental covariates. Model evaluation revealed that Indigenous resistance was the top-ranked predictor of forest survival in the region and a counterfactual simulation predicted that resistance reduced forest cover loss by 20 to 22% between the colonial period and the 1960s. These results highlight the historic importance of Indigenous resistance and indicate that researchers and policy makers should allocate more attention to the conservation effects of historical Indigenous actions.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "J7XAWT", "name": "Barney Harris", "avatar": null, "biography": "Computational Archaeologist at the Institute for the Modelling of Socio-Environmental Transitions (IMSET) within the School of Life and Environmental Sciences at Bournemouth University.", "public_name": "Barney Harris", "guid": "57557561-7be4-56fe-8b1e-e02206fa7535", "url": "https://talks.osgeo.org/foss4g-uk-2026/speaker/J7XAWT/"}], "links": [{"title": "Talk slides", "url": "https://barney.fly.dev/caa-2026-vienna/caa-vienna.html#/", "type": "related"}, {"title": "Analysis repository", "url": "https://codeberg.org/barneyh/indigenous-resistance-analysis", "type": "related"}], "feedback_url": "https://talks.osgeo.org/foss4g-uk-2026/talk/A9KLJX/feedback/", "origin_url": "https://talks.osgeo.org/foss4g-uk-2026/talk/A9KLJX/", "attachments": []}, {"guid": "81505d4e-7049-5894-bb06-1353cbce20da", "code": "KAMESJ", "id": 6220, "logo": null, "date": "2026-10-12T14:00:00+01:00", "start": "14:00", "duration": "00:30", "room": "Create 1", "slug": "foss4g-uk-2026-6220-openstreetmap-at-its-core", "url": "https://talks.osgeo.org/foss4g-uk-2026/talk/KAMESJ/", "title": "OpenStreetMap at its Core", "subtitle": "", "track": null, "type": "Talk", "language": "en", "abstract": "OpenStreetMap data is used in many of our projects, and many of us have experience with contributing as volunteer mappers too.

We can map it, model it, render it and query it. Yet representation is not understanding. A coordinate is not a place. A building footprint is not a building.

It requires spatial memory, continuous observation, simulation, context and reasoning. The future will not be defined only by larger models, geometries or attributes, but by better representations of the world: representations that capture context, relationships, change, history and meaning of its existence. \r\n\r\nIn this keynote, I will explore the transition from geospatial data to spatial intelligence.

Navigating Ordnance Survey's catalogue is harder than it should be and even getting the right license can be difficult. At Rebalance Earth we use geolocated address data for identifying properties owned by pension funds and asset owners that are at risk of flooding so that we can propose nature-based flood management solutions to mitigate that risk. \r\n\r\nAs part of our flood risk reporting process, asset owners often send us a list of property addresses associated with individual commercial buildings, retail parks with several buildings, hospitals, or entire industrial parks. But for flood reporting we need polygons, and even the OS AddressBase data only gives us addresses as points. So, we had to find a better way of turning raw address strings into accurate, georeferenced polygons. \r\n\r\nTo do this, we built the Locator App: a CLI tool that stitches together several open-source geospatial datasets and uses a tiered address matching system to find or create a georeferenced polygon for every address in a list. The app works best for geolocating large areas with lots of buildings like retail parks, industrial estates, or commercial properties, rather than residential addresses. \r\n\r\nThis talk is about how we built the Locator App and why it matters beyond our own work. I want to share what tools we used, including Python, GDAL, pg_tgrm for fuzzy name matching, Claude for building the interface, and the open data we used such as OS Overture Places and OSM Land Use.

It geocodes tabular data using UK-native identifiers - postcodes, UPRNs, Eastings/Northings, and GSS statistical codes - the last of these automatically resolving to the corresponding ONS boundary (LSOAs, MSOAs, wards, local authorities, and many more) by querying the ONS Geoportal directly, with no boundary file management required from the user.\r\n\r\nThe visual supports choropleth and point maps, custom geometry upload (GeoJSON, WKT, TopoJSON, shapefile), and two-way cross-filtering with other Power BI visuals. All of this runs inside Power BI's sandboxed custom visual API - a constrained environment that creates its own engineering challenges.\r\n\r\nOrdnance Survey has released the visual as open source under an MIT licence.

While downsampling preserves broader spatial context, it sacrifices fine-grained detail. Conversely, slicing imagery into discrete tile grids introduces arbitrary boundaries that bisect objects and isolate features from their surroundings. Consequently, downstream detection and segmentation models receive truncated context, compromising inference quality. While overlapping tiles offer a partial mitigation, they merely shift the burden to complex post-processing required to resolve conflicting predictions.\r\n\r\nIn this talk, we present a novel solution to bridge tile boundaries using the latest vision foundation models like DINOv3. DINOv3 processes raw imagery into uniform token grids, where each patch embedding captures rich, high-dimensional spatial context without relying on human annotations. By comparing these embeddings, semantically and spatially coherent patches can be clustered across an image. We demonstrate how this unsupervised clustering capability extends beyond individual tile boundaries to encompass arbitrarily large regions. This approach reduces reliance on tile overlaps and lossy downsampling, equipping downstream detection and segmentation models with the unbroken context needed to accurately delineate complex geographical features.\r\n\r\nTo highlight its practical value within geospatial workflows, we demonstrate our Pytorch pipeline and showcase its performance against a diverse range of satellite and aerial imagery datasets.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "XMHBBA", "name": "Madeleine Darbyshire", "avatar": "https://talks.osgeo.org/media/avatars/XMHBBA_GzOM0M0.webp", "biography": "Madeleine holds a PhD in computer vision for agriculture, with industry experience applying geospatial computer vision to agricultural operations.

Using materials from the [MAHSA project (Mapping Archaeological Heritage in South Asia)](https://www.mahsa.arch.cam.ac.uk), participants will work with digitised Survey of India (SoI) map sheets (1905-1950s) using hands-on exercises. MAHSA is an ongoing collaborative documentation project at the University of Cambridge, funded by Arcadia. With more maps being made available online, navigating and applying historical maps in geospatial research and documentation can be highly complex. This workshop provides a practical end-to-end, open-source workflow to access, transform, visualise, and organise historical maps using some of the latest geospatial technologies, such as IIIF, STAC, Cloud Optimised GeoTIFFs (COGs), Arches, and QGIS.\r\n\r\nThe workshop is structured around three short hands-on exercises. 1) Participants will georeference a digitised map sheet from the [MAHSA Arches database](https://databasemahsa.org/), an open-source geospatial database platform using the related IIIF URL from library repositories. 2) Participants will subsequently explore a STAC catalogue of publicly released MAHSA maps, filtering by map date and extent before loading selected Cloud Optimised GeoTIFFs (COGs). 3) Participants then learn how to remove sheet margins using the MAHSA SoI Map Clipper (an internally developed open-source QGIS plugin).\r\n\r\nThe workshop concludes with a discussion of broader applications for historical map workflows and applications. Within MAHSA and beyond, historical maps support applications such as automated feature extraction, long-term landscape and settlement analysis, and many other forms of spatial analysis. In the discussion, we invite participants to provide feedback on how the presented tools might support different research and public-facing uses. As well as reflect on the challenges of IIIF and STAC to build sustainable infrastructure for the use of historical maps that can serve researchers, organisations, commercial users and the wider public.\r\n\r\n## **Prerequisites**\r\n\r\nA laptop with a browser, an internet connection, and QGIS 3.44 (LTR) installed.

Example local history and naturalist groups include the now-disbanded Plinian Society, founded in 1823 in Edinburgh and whose membership included Charles Darwin, and the Woolhope Naturalists' Field Club founded in Herefordshire in 1851, which still runs to this day.\r\n\r\nA wide variety of established methods are available to landscape historians, ranging from desk-based collection, translation and synthesis of information from historic archives to the field-based observation of biodiversity and methods requiring scientific equipment including dendrochronology, ground-penetrating radar, and radiocarbon dating. The use of geographic datasets and methods such as remote sensing, georectification and digitisation of historic maps, and communication of results through interactive maps are relatively new developments that offer great potential to empower many current and potential landscape historians of every stripe.\r\n\r\nHowever, the knowledge and skills needed to collect, work with, and gain insights from geographic datasets for landscape history are few and far between, with expertise concentrated among a few people working at the intersection between landscape history and the broadly defined field of geocomputation.

Two important datasets are flood defence lines, which denote the location and key attributes of assets on the ground, and defended areas, representing the geographical areas protected by those assets. Although closely related, these datasets are maintained independently, creating spatial inconsistencies that can affect downstream analysis.\r\n\r\nIssues became apparent when calculating the costs associated with defences within national investment planning tools. Maintenance and operational costs are reported at the defended area level and individual defence lines frequently span multiple defended areas. Cost allocation therefore relies on spatial intersection analysis and unit-cost calculations. Where defended area boundaries are not correctly aligned with defence lines, costs can be under-reported, affecting economic assessments and future investment decisions.\r\n\r\nTo address this challenge, JBA developed an automated GIS workflow using Python. The workflow identifies defence lines that are not correctly connected to defended area polygons using near-table analysis and distance-based calculations. Polygon vertices requiring adjustment are identified automatically, and translation vectors are generated between those vertices and their nearest defence line. These vectors are then used to reshape defended area boundaries, improving alignment while maintaining user control through configurable tolerances and filtering options.\r\n\r\nThe workflow is executed from the command line and has significantly reduced the manual effort required to review and correct defended area boundaries. Quality assurance is supported through the creation of intermediary outputs that visualise every vertex translation, allowing analysts to review and validate automated changes before acceptance.\r\n\r\nThis presentation will describe the challenge, spatial analysis techniques used and lessons learned. It will also explore the balance between automation and manual intervention when maintaining large, interconnected geospatial datasets. Whilst some complex line-polygon interactions still require manual editing, the approach has substantially improved the data quality and reporting accuracy that underpins key investment decisions.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "FLSVZT", "name": "Philip Midgley", "avatar": "https://talks.osgeo.org/media/avatars/FLSVZT_K9YCDwR.webp", "biography": "Phil is a Project Manager, Software Developer and web-GIS lead at JBA Consulting, an employee-owned environmental and engineering consultancy.
