This is the second post covering days 11-20 of the 30 Day Map Challenge. The first 10 days were previously posted. As a reminder, these are the themes
Day 11 – 3D
this is Sable Islands Bald dune from the north beach (looking east). The landcover is derived from 30m resolution landsat data using NDVI. ground is NS DEM, with generated Hillshade and contours.
Day 12 – Population
since the 2021 census data doesnt come out until the 17th, for day 12 i was forced to use 2016 data. I used the Population and Dwelling table joined to the dissemination area shapefile. you can really tell the suburban areas with high-rise development.
Day 13 – Natural Earth
the challenge for this map was to use data from natural earth. This map depicts the time zones of Atlantic Canada, and everything you see here was done with Natural Earth data.
Day 14 – Map with a new tool
I used tableau to tutorial a weather map based on a turtorial i found online. Tableau is annoying.
Day 15 – Map without a computer
Halifax harbour, free hand on paper
Day 16 – Urban/Rural
for this map I show the urban and rural firefighting water supplies. Each red dot represents a fire hydrant. Outside the dotted areas, firefighters are using a dry hydrant, or drawing directly from a body of water. Data is from Halifax Open Data Portal. Hydrant Dataset, Dry Hydrant dataset, fire response zones dataset
Day 17 – Land
The full island map from Day 11. Same Data, and everthing, just in a normal map view.
Day 18 – Water
A rough approximation of CHS Chart 4203 Pt.Pleasant to Black Point. Constructed with CHS NONNA 10m data. Navigational Markers were built from the List of Lights, Buoys and Fog signals publication. A how to was posted previously.
Day 19 – Island(s)
Georges island. Custom POI layer, otherwise 1m DEM and water polygons.
Day 20 – Movement
for day 20, i animated the points of ship movements in the harbour on Nov 14. Some of the Ferries are noticeably missing – They Carry a Class B AIS receiver, which uses a different data format, and so i dropped it. (A Bigger version also can be had here)
