A few new updates to make things a bit easier: 1. When setting the angle for a control label, the label now updates in real time, so you no longer have to guess where the label will end up. 2. If you double-click on the control number/description on the right-hand control description panel, the map…

Hot on the heels of England’s LIDAR update, the Welsh Government have released their data from LIDAR surveys in 2020 – 2022. This dataset has a few gaps, in particular some coastal regions, but these were almost entirely covered in their older data. As a result, the combination of old and new LIDAR data gives…

The Environment Agency released their latest composite LIDAR-based digital terrain model for England last week. They state >95% coverage across England but it looks to be complete apart from a circle around Fylingdales in North Yorkshire. I’ve spent the last few days processing this and merging in with the Welsh LIDAR data to generate an…

This site has been up and running for some time now, however most traffic has been going to Ollie O’Brien’s original site at https://oomap.co.uk A week or so ago, the servers used by Ollie’s site were upgraded, which broke the site. Therefore at least for now, all oomap requests are coming here – and it…

When you download a PDF map, the mapping nicely fits inside the outer border. It’s not that simple however – the mapping data often extends beyond this border, but is visually clipped so that only the data inside the border is shown. Any external data is still there, but hidden – and takes up space…

The current contour generation process queries a database for all the contours in a certain area. It then drops any very short contours as these are likely to be artefacts that aren’t useful, and draws tick marks to show slope direction. To make sure the ticks appear on shorter contours, the frequency of tick marks…

Although Scotland’s Environment Protection Agency makes available its LIDAR data (at https://remotesensingdata.gov.scot/data#/list), it isn’t easy to download the data in bulk, so I’ve not been able to download the full dataset and use to generate contours. The data is available as 5 separate datasets that overlap considerably, downloadable only as small areas (5km x 5km)…

The LIDAR data at https://oomap.dna-software.co.uk/ currently covers around 85% of England, including most urban areas. Annoyingly there have been significant gaps in the coverage in my home county of Hertfordshire, which have meant that some of our Street-O events have been unable to use LIDAR contours. While the composite English LIDAR dataset is incomplete, individual…

I’ve just reactivated a hidden option in oomap, which is to allow the map creator to tag the event with a club name, selected from a drop-down list. As well as tagging the event (for possible future use…), the renderer picks up the club name and adds the corresponding logo to the top-right corner of…
