Experimenting with my own Map Tooltips manager and Real World Symbol sizes at high zoom levels.
A first draft at sharing a universal layer management library that is mapping framework and UI library agnostic. We've utilised this approach to create our own layer management in Leaflet and ArcGIS applications without having to reimplement shared logic! antarctica.github.io/universal-la...
I've created an open-sourced version of my logic for accessing a nmea feed on a usb gps device (or any nmea serial port!) Take a look here: github.com/antarctica/n...
Recently I stumbled upon the web serial api! Supported in Chromium browsers, it allows you to hook into a devices attached to serial ports on your machine through the browser! I've implemented logic to read in a gps nmea stream directly into our SIIS web app!
More timelines! Two way interaction between our custom Imagery Collection Layer and the timeline! #timelines #arcgisdev
Working on adding some timeline user interface components to simplify the process of choosing relevant data. In this case we a bring COGs directly into the app from a STAC api! #arcgisdev
Building a timeline using d3.js. Sometimes its easier to roll your own then search for that golden goose library that someone else has built! Pretty much unstyled at the moment, but has the functionality I need for handling interactions.
A photo of a man launching the ebee UAV in a grassy field. There are trees in the distance and white fluffy clouds in a blue sky.
A photo of 2 men, one of them holding an ebee UAV, in a grassy field. There are trees in the distance and white fluffy clouds in a blue sky.
Made primarily of polystyrene they weigh just 1.6 kg on take-off, but despite this they are capable of operating in the stronger winds we experience down in the Antarctic with a maximum continuous wind limit of 17 m/s. In fact, yesterday we clocked a top ground speed of >63 mph!

MAGIC was out test flying our eBee VISION platforms in advance of the upcoming Antarctic field season this week. The eBee VISION UAVs can fly for 90 minutes and operate up to 20 km from the pilot. Here's a short clip of one of them in action! 🛩️

A screenshot of 59,261 spot heights in West Antarctica and the Antarctic Peninsula. This is the initial version, before reducing the density. Each point is shown as a red dot, the coastline of Antarctica is displayed as a grey line, and the yellow squares are the extent of some of the REMA tiles.
Lots of dots! These are spot heights generated for our Air Operations Planning Maps, using REMAv2 2m tiles. Next steps are to clean up the density, add existing GPS points & then add them to our maps, which are used for planning by pilots across the continent. The data will then be openly published!
A screenshot of a SAR image at the north-east end of the Antarctic Peninsula. The digitised ice floes are highlighted in semi-transparent green. The image is from 31st Dec. 2020.
A zoomed in portion of the SAR image in the Weddell Sea. The digitised ice floes are highlighted in semi-transparent green. The image is from 31st Dec. 2020.
We are currently hosting an intern digitising ice floes from satellite radar (SAR) imagery in the Weddell Sea.
The resulting labelled data will be used in the NERC DEFIANT and QUASAR projects to assess the performance of machine learning methods and quantify errors in sea ice concentration data.
Just finished building a gazetteer search component on top of the ArcGIS SearchViewModel! Its running off of a set of geoserver WFS services with a custom locator layer source! Working really neatly! #ArcGIS #Maps
A photo of BAS's red Twin Otter plane in a hangar/workshop. A Canadian flag can be seen in the background.
We have been working along with engineers from Phase One and Rocky Mountain Aircraft over the past week to install and test our new Phase One PAS aerial camera into BAS's Twin Otter aircraft. 🛩️

A screenshot of a map showing the location of the RRS Sir David Attenborough, travelling north off the west of Africa. A globe inset shows the location in a wider context.
Did you know that it's possible to follow the RRS Sir David Attenborough on @bas.ac.uk's website? We provide the maps and location tracking to underpin this. 🚢🗺️
See the latest position of the ship here, on its way north after a long season in Antarctica! www.bas.ac.uk/polar-operat...
Photo looking from Stork Ridge down to Sheldon Glacier showing part of the view that our fixed cameras will capture. The image shows the view from a rocky outcrop looking down on a crevassed glacier with water in front of small icebergs are floating in the water.
This week we have been at a @polomints.bsky.social project meeting, planning details of how to use fixed stereo cameras, RPAS and our new air camera to monitor calving of the Sheldon Glacier on Adelaide Island. For more information visit polomints.ac.uk.
A snapshot of a map application showing the pixel difference highlighted during an automated testing run. The difference shows that some labels are no longer being rendered on the map at certain positions.
Whilst updating an app to the latest version of the ArcGIS JS API (4.33) we picked up a minor regression in labelling for a super niche situation. I would call that one epic win for our automated testing setup! Check out our setup here: github.com/antarctica/e... #Arcgis #Dev #Playwright
I’ve used it a lot. GitHub copilot integration has got a lot better in normal vscode, but still doesn’t feel as intuitive and seamless as cursor for me… the tab multi line complete is just so slick!
I always like to get in early with implementing a responsive UI - usually it means that the actual extra code is pretty minimal! #arcgis #responsive
6 small maps of regions in Antarctica and South Georgia. These are examples of typical Helpdesk outputs from the job being advertised. Each map contains place names, bathymetry in shades of blue, and terrain details on land.
A map of Signy Island, South Orkney Islands. This map is part of our BAS Topographic Map Series. Bathymetry is shown in deepening shades of blue. Details on the land include ice and moraine extent, lakes, contours, and place names.
We're hiring a GIS and Mapping Specialist to manage our Geospatial Helpdesk and to contribute to our Topographic Map Series.
This is a really exciting opportunity at the British Antarctic Survey to support colleagues across the organisation. Details here: shorturl.at/bA4fd #GISjobs
We've been developing a new application with ArcGIS Maps SDK to create a simple UX for exploring our imagery archive - We pull on lots of the existing widget view models but tweak them to create out own workflow and design system. Map and workflow logic is orchestrated by XState. #arcgis #arcgisdev
A photo of Dr Robert Mulvaney showing a map of of Ny-Ålesund and the Kongsfjorden region in Svalbard to visitors at the NERC Arctic Office. The visitors include the UK Foreign Secretary Rt Hon David Lammy and his Norwegian counterpart Espen Barth Eide. The photo shows 5 people stood around a map laid on a table, with one man filming.
Great to see our map used by UK Foreign Secretary Rt Hon David Lammy and Espen Barth Eide during their visit to the @ukarcticoffice.bsky.social in Ny-Ålesund recently. With summer/winter versions, it shows how fast the region changes and why frequent, detailed mapping in the Arctic is so important.
Just finished a little refresh of Sewagemap.co.uk. Added a fun loader, and additional layer filtering bits and bobs! It continues to show a bleak picture of sewage overflow in the uk... 💩😔 #sewage #uk #arcgis
An image of Rothera Research Station, Rothera Point, on Adelaide Island. There is a bright blue building in the centre of the image which is the new Discovery Building. You can also see patches of snow on the point, and there are small icebergs floating in the surrounding water.
A zoomed in portion of the image, showing the northern end of the runway and the hangar. A white and red plane can also be seen, parked next to the hangar.
A zoomed in photo of the plane. The plane is red and white. It is possible to see skis in front of it, probably removed from the plane as it continues its journey north away from Antarctica.
A few months ago, we surveyed Rothera Point using our fixed-wing eBee-X UAV. We've now processed the data and produced this beautiful, orthorectified mosaic, as well as a Digital Elevation Model.
We carry out these surveys every year, allowing all of BAS to work with current and accurate data!
Text reads "eternal reminder that you may go to settings and then accessibility to enable required alt text, so you'll never forget again. it's the right thing to do."
A photo of the trophy and certificate, with side A of the Bedmap 3 map shown behind. The map shows the bed topography of Antarctica underneath the ice.
We're proud to share that our Bedmap3 map won "Best Map" at the International Map Industry Association (IMIA) forum in London last week! 🏆
This international award celebrates Outstanding Cartographic Design & we’re honoured to be recognised alongside leading names in the field from previous years. 🗺️
