Towards the end of October 2019 twitter user @tjukanov announced the #30DayMapChallenge. The Geomni UK Team loved the idea and couldn't resist getting involved. The challenge set was to create a different map every day throughout November which lined up to the themes set for that specific day. The poster for the Map Challenge shown below lists these themes.
Day 2 - Lines
Flight lines over Paris from a survey taken in 2018.
The spacing represents how the project had to be broken up into individual sections to ensure a constant resolution whilst also working around the restrictions on altitude.
Day 30 - Homes
Last but not least, a map showing the spread of Victorian homes across London.
The maps give a good indication of the expansion from Early Victorian (dark red) to Late Victorian (orange).
