#30daymapchallenge Day 21: Icons. I rifled through the OSM legend to pick an icon. Brighton Pubs. The City is famous for having a high density of them. Given current cost of living challenges, many are struggling. Use them while you can.

I had the honour of meeting Mani in Cologne in 1995. He was so keen to meet everyone who had come over to see them, wanting to know all our names and where we were from.

My map uses #Sentinel1 images before/after the 2018 Lancashire #wildfire in the UK.
The dashed line shows the fire extent, which burned dry #peatland.
The colour range blue to yellow symbolises how radar represents wetter surfaces through to impermeable land cover.

These images were only 23 days apart in winter 2022/23 in the West Pennine Moors, but demonstrate #Sentinel1 radar differences due to temperature. Our research found S1 images in frozen conditions could better delineate peatland & show differences in wetness.
