Property Price Search
The Isle of Man now has its own open property price search. Built on 40,000+ land transactions from the IoM Land Registry dating back to 2000, the new Property Price Search lets you look up any property sale on the island by address, town, parish, price range, or year.
What you can do
- Free-text search across street names, addresses, towns, and postcodes
- Filter by town, parish, price band (under £100k through to over £1M), and year range
- Sort by any column — address, town, price, or date
- Server-side pagination across the full dataset with smart page navigation
Transaction history
Click any row and the panel expands to show every recorded sale at that address. You can see how a property's value has changed over the years, with percentage changes between each transaction and an overall gain or loss from first sale to last. It is the kind of transparency that helps buyers, sellers, and researchers understand the Manx property market.
The data comes from the Isle of Man Land Registry public records, updated monthly. Nominal transfers under £1 are excluded.
Ecosystem Map Redesign
The Biosphere Ecosystem map has had a significant visual overhaul. The hex grid now covers 1,947 hexes at H3 resolution 8 (roughly 0.74 km² each), classified into six biome types: forest, farmland, coastal, wetland, upland, and urban.
What changed
- Full-viewport map — the map now fills your screen from its position downward, no more fixed-height box
- Overlay panel — clicking a hex opens a translucent detail panel on the left side of the map, rather than a tooltip. It shows the biome, health score, species count, observations, tree cover, elevation, taxonomic group breakdown, and representative species
- AI species illustrations — when generated, the panel displays AI-created naturalistic illustrations for the representative species in each hex, replacing the smaller GBIF thumbnails
- Floating view toggle — switch between biome colouring and health score gradient via a compact pill in the top-right corner
- Elevation-based classification — upland and moorland hexes are now identified using SRTM 30m elevation data from OpenTopoData, replacing the previous NDVI approach which had data availability issues
Heritage map
The Heritage page now includes an interactive map plotting 327 registered buildings across the Isle of Man. Each marker shows the building name, parish, era, and registration status, with clustering for areas with many listed buildings. Filter by parish, era, or registration status to explore the island's built heritage.
Data & Attribution
The Biosphere Observatory is built on species occurrence data collected and curated over decades by Manx National Heritage, the National Biodiversity Network, Manx Wildlife Trust, Manx BirdLife, and many other partner organisations and citizen scientists. The Calf of Man Bird Observatory dataset alone — a collaboration between MNH and MWT — contributed 438,000+ records spanning 45 years. This platform would not exist without their decades of fieldwork, expertise, and commitment to open data.
What's next
The property search will gain additional features over the coming weeks, including area-level price statistics and trend charts. The ecosystem map will be populated with AI-generated species illustrations for the top biodiversity hexes. We're also building a comprehensive Data Provenance page to properly attribute every dataset and contributing organisation.
