Tree planting survey 1-2-3

New Flamingos, my Extinction Rebellion group in Cambridge decided to do a little outreach - not unlike my other group On the Edge that engages with my village around flood preparedness - we work with the community to replant trees along the left bank of the River Cam immediately North of Cambridge UK. This afternoon, a tree surgeon accompanied our survey along the river bank and suggested tree location and density as we walked.

One affiliate insisted on having exact locations and suggested what3words. I downloaded their app on my smartphone, and simply tapped in locations with the tree surgeons running comment: "x trees here", "a coppice there", "20 trees until the bridge" etc. After returning home, I simply exported the .csv file and poked around what3words website to see if I can map this. Presto! they had all the info to hand and I created this web map in about half an hour:

Update 1: see "Explore Mars with GIS", the app and the story HT @PhilipMielke ]

Poster catalogue

[ Update 2: Anaglyph 3D pops up Central Cambridge halfway down under Other Areas

Update 1: added four effects to enhance relief maps on mountain areas at the bottom ]

Last month's Story-in-a-map reminded me I created a number of map posters, as a mean to reach out to the community, where prints are better in town hall or small group presentations, as well as wall art.

Coronavirus update - Part XII

[ Update: NHSx cases and ONS deaths continue to show signs of easing up as vaccinations go on ]

Since our previous update, a third national lockdown resulted from the numbers that just keep increasing, as well as a second strain of the virus appearing but not split out in NHSx stats. That is patent in the comparative graphs below, updated as per above:

Story-in-a-map

[ Update: see Update #7 in this story map on how to address topo inversion (#6 is this) ]


 While I have written a few story maps, the #30DayMapChallenge last month has taught me to tell a story in a single map. The amazingly detailed DEFRA digital terrain model has already been used here (go to Update 1) in the Cambridge area of East Anglia. So here is a synoptic view of South Cambridgeshire, with its story in the box.
