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)

Over on Twitter i have been participating in the #30DayMapChallenge. the challenge consists of 30 themes, with the idea to produce a map for each one. This post summarizes the challenge, and includes information on the data sets used. A full explanation of the themes can be found on github.

Common Data Sources
these are some common data sets that I frequently come back to.
HRM Building Outlines – polygons representing building footprints
HRM Street Centerlines – centerlines of streets, with names
HRM Active travelways – sidewalks, paths and trails
HRM Lidar DEM 1m – 1m resolution lidar data from 2017.
Canadian Boundaries – Canada land forms and provinces.

Day 1 – Points
the First 3 days of the challenge focus on the 3 kinds of Vector GIS Data, Points, Lines and Polygons. Points maps marine occurrences since 1975 reported to the Transportation safety board, and maintained within its MARSIS database. Bathemtry is from GEBCO

Day 2 – Lines
Lines come from the Canvec National Railway Network, and depict CN and CP rail lines around Vancouver harbour.

Day 3 – Polygons
i used a collection of data from Halifax Open data to extract the building footprints form the heritage property data set. Also used are the cities 5m contour, road network, and parks and active travel ways data sets.

Day 4 – Hexagons
hexagons make a cool unit for showing density. the city has street tree point data available, so i mapped density of street trees per 50m hexagon.

Day 5 – Open Street Map
using leaflet.js, i apply aircraft tracks picked up from my adsb receiver to an open street map basemap. The goal was to use OSM Data. done.

Day 6 – Red
2019 Election results showing a strong liberal win. Data from elections Canada, Results merged with federal electoral districts

Day 7 – Green
National Parks in Atlantic Canada. I used the Official Parks Canada Greens for this map, and their Helvetica Neue font as well. Parks data came from the Canadian Protected and Conserved Areas Database (CPCAD). hillshade is extracted from Gebco.

Day 8 – Blue
with a blue theme, i chose to map Blue Mountain Birch cove lakes protected area. The city owns the land highlighted in purple, but the goal is fill in in the park. there are advanced discussions underway for the area to receive national urban park status.

Day 9 – Monochrome.
This map was made with the Province of Nova Scotia’s Digital Terrain Model data, and Roads, Trails, and Rails overlayed. it gives a nice texture to the province, showing both the form of the land, but also human settlement. Both datasets are available via GeoNova

Day 10 – Raster
using the cities 1m lidar DEM, i extracted Point Pleasant park using the cities park shape file. the 1m resolution lets you clearly see paths through the park, and the remains of the old military installations.

Earlier this month a spent a week on Sable Island. I volunteered to assist with the construction of some fencing as part of a research project being undertaken by Parks Canada and the Sable island Institute. While i was on the Island i tweeted various photos and observations. This series of posts will rehash alot of that content, and hopefully provide some more context to it.

Sable island is located about 150nm off the Nova Scotia coast. it is made entirely of sand deposited by the leading edge of a glacier when it receded during the last ice age. There are no rocks on the island, but there is fresh water. Due to its position, the island is often windy, but even in winter seldom drops below -5C. My week on the island featured uncharacteristically good weather, with sun most days and temps in the high teens and low twenties. (there were some rain showers one afternoon, and we did have a day with 40knot winds)

The island is largely vegetated, with a combination of grasses and heath. There are introduced plants – Cranberry, roses, and a lone sad pine tree.

Currently you can visit sable island. the island is only open for day visits, and thee is no public accommodation on the island, and camping is not permitted. To Fly, Sable Aviation, Vision Air, and Breton Aviation all offer flights. Our ride to the island was via Vision Air’s S-76a. We landed at the main station helipad

Sable Aviation provided are ride home. They operate a Britten-Normander Islander Aircraft, and use the beach near main station as a runway. wind had blown loose sand drifts across the landing area which is why the helicopter was needed.

Main Station is the hub of habitation on the island. It was originally maintained by the Meteorological Service of Canada, but was taken over by parks Canada in 2013.

the long building is the Garage/maintenance shop/and generator building. There is also the Staff House (now known is the VQ, or Visitors Quarters), and the OIC House. the two distant buildings are the hydrogen building, used by MSC to launch weather balloons, and MSC’s lab. the dome contained instruments to track the balloons.

(above)Staff House (Below) my room. In non covid times, the house can sleep around 20 people. there are a couple of rooms outfitted for single use, others meant to be shared. due to covid, it was one to a room. there is a Large Kitchen, and a lounge space.

The front sunroom area was reserved for day use visitors.

Transportation on the island was primarily via Jeep Rubicon with balloon tires. Gators, a Polaris, and ATV’s were also in use. (the drive belt on the Polaris broke, and we needed to tow it back to main station.)

one last thing about sable. being a relatively flat bit of land in the middle of the ocean, tsunamis are a concern. Main Station features two 7 person lifeboats should a large wave be detected heading towards the island.

The 4253TEU container ship ZIM Kingston is currently on fire, while at anchor at Constance Bank, off Victoria BC. The ship had sailed from Busan, South Korea for Vancouver.

On Friday Oct 22 the ship reported loosing 40 containers in 20′ seas just after midnight. the ship was 43 miles west of the entrance to the straight of Juan de Fuca when the containers were lost. The ship did some odd manoeuvring where the containers were lost.

ZIM Kingston then proceeded to anchorage in Constance bank. From photos it looks like lost containers are from two stacks, one forward and aft. Several of the lost containers were later spotted by USCG Aircrews, and noted to be moving north. A gale warning is in effect, with winds of 20 knots, increasing to 40 Monday.

On Saturday morning around 11am, the ship reported that damaged containers were on fire.

The crew was advised my MCTS to abandon ship. 10 members were removed by the coast guard and taken to Ogden Point. after a small explosion, an additional 6 crew were removed.

As of Saturday Night, 16 crew had been evacuated from the ship by CCGS Cape Calvert and CCGS Cape Naden, with 5 including the captain remain on board. The CCGS reported 10 containers were on fire. 2 of which are self combustible (Class 4.2) potassium amylxanthate — which is used in the mining industry.

Looks like they pushed a flaming container off the #zimkingston pic.twitter.com/BFqDjeO8vY

The ships owner had contracted salvagers, and Maersk Tender and Maersk Trader have responded. these ships were in the area, and normally operate ocean cleanup equipment to remove plastics from the water.

UPDATE photo of #ZimKingston as seen from #CloverPoint #VictoriaBC 🇨🇦 at 7:30 am Sun. Oct 24. Crews still spraying container ship with water, is that a speck of flame I see on board still? pic.twitter.com/5XUTcN7IvU

Seaspan Raven has also on scene since Saturday. Due to the the chemicals on fire reactivity to water, water is being used to cool the surrounding areas of the ship but not directly attack the fire.

As of this morning, the Atlantic Raven, which is under contract as an emergency towing vessel for the coastguard is on scene, and the fire is reportedly still burning.

Additional Updates as they become Available.

UPDATE: there is currently a news conference on Now. The fire is reported to be out, but there is alot of heat and smouldering. crews will attempt to extinguish the fire onboard the ship tommorow.

last night a single craned worked the emskip vessel Selfoss at pier 42. Selfoss sailed at 1am this morning.

Over at AtlanticMX.ca I have assembled Marine Occurrence data, and mapped it.

The data was obtained from the Transportation Safety Board’s MARSIS Database,
and contains over 48000 incidents in Canada, and involving Canadian Vessels from 1975 to June 2021.

Each point represents a reported occurrence, and clicking it will provide basic details about an occurrence, and an occurrence narrative. Note older data can be problematic, and some locations are approximate.

The MARIS Database is a series of CSV files containing details on Marine occurrences. These files were joined, and a Json file generated which is used to render the Map Above. The files are updated on the 19th each month.

CSS Acadia was towed from the Museum wharfs by Atlantic Larch, bound for a work period at shelburne ship repair. The hull will have corroded steel replaced, and other work done to ensure the ship stays afloat for the next 100 years.

Alas the harbour was covered in a thick layer of fog, and this was the best picturei could get of the tow.

I had forgotten that i did an overview post of the 2016 Olympic sailing, so here is the 2020 version. For Tokyo, Canada is sending a 9 person sailing team.

In fleet racing, sailboats start at the same time and sail around a course (usually marked by buoys) a predetermined number of times. Boats are then scored by the position in which they finish (ex. position 1 get 1 point, 2end two, etc.). The sailor with the least points at the end of competition wins the competition. A competition is made up of multiple races. at the end of the series, the top 10 boats will sail in the medal race.

Live streams can be found at https://www.cbc.ca/sports/olympics/summer/sailing/streaming-schedule . note this often the raw IOC feed with no commentary.

ICLA 6 (aka Laser Radial)

Sarah Douglas will compete in the Laser Radial. The Laser Radial has been the Women’s Olympic Dinghy since 2008. The Hull is identical to the laser, but the radial uses a smaller sail(5.7), shorter lower mast section and has a different cut of sail to that of the standard. It is optimally used by someone in the 120-160lbs range.

470

Oliver Bone and Jacob Saunders of the Royal NS Yacht Squadron will compete in the 470 2 person Dinghy. The 470 was designed in 1963 by the Frenchman André Cornu as a modern fibreglass planing dinghy to appeal to sailors of different sizes and ages. In 1969, the class was given international status and it has been an Olympic class since 1976. In 1988, the first Olympic women’s sailing event used the 470. The 470 (Four-Seventy) is a double-handed monohull planing dinghy with a centreboard, Bermuda rig, and is equipped with a spinnaker and trapeze.

Jacob Saunders competed in this class in 2016 with his brother.

Finn

Tom Ramshaw will sail in the Finn Heavy Dinghy.He Competed in this event in 2016 as as well.

The Finn dinghy is the men’s Heavyweight Dinghy at the Olympic games. Like the laser, it is a single-handed, cat-rigged boat. It was designed by Swedish canoe designer, Rickard Sarby, in 1949 for the 1952 Summer Olympics in Helsinki. Since the 1952 debut of the boat, the design has been in every summer Olympics, making it one of the most prolific Olympic sailboats as it is the longest serving dinghy in the Olympic Regatta. The fin Weighs 230lbs, is 14’3″ long, and carries 114sqft of Sail.

RS:X

Nicola Girke in compteing in RS:X. in 2016 she was 1/2 of the mixed Nacra 17 team.

the RS:X is a windsurfer designed in 2004 by Jean Bouldoires & Robert Stroj.

49er

Canada is also sending both a men’s and women’s team for the skiff event. Ali ten Hove and Mariah Millen sail in the  women’s 49er FX, and William Jones and Evan DePaul in men’s 49er. 

49er FX is a two-handed skiff-type high-performance sailing dinghy. The 49er was designed by Julian Bethwaite and has been in every olympics since its debut in the Sydney Olympics of 2000. The FX uses a smaller rig then the standard 49er, and is the Womans Olympic Class Skiff. The 49er’s name comes from its hull length of 4.99 metres. It weighs 207 lbs.

The designer of the Laser sailing dinghy has died. 

Bruce Kirby passed away on July 18. He was 92. Born in Ottawa, and grew up sailing on the Ottawa River as a member of the Britannia Yacht Club. He worked as a journalist, before becoming editor of Yacht Racing magazine. He competed at the Olympics three times as a sailor, in 1956, 1964 and 1968. 

Kirby went on to design a number of sailboats, including two used to contest the Americas Cup, but he is best known as the designer of the Laser. The first laser was built by Kirby in 1970. Since then, over 215,000 have been produced, making it one of the most popular sailboat designs in history. 

The impact of the laser has been immeasurable. The early design was intended to be easy for one person to handle, and transport on a top of a car. The lasers hull is 13′ long, and the boat weighs 130lbs, which is downright portable for boat. The laser is cat rigged, meaning it uses one sail, and has a removable dagger board and rudder. 

Being simple to sail, it is often one of the first boats people learn to sail as children. Every summer you can see fleets for kids sailing the laser on the North West Arm. The Laser has also been an Olympic Class since 1996. The fact that the design is simple enough to learn on, but also able to support Olympic level competition is telling. 

Bruce Kirby lnc. licensed the laser design to manufacturers and collected a royalty on each one. In 2013 he revoked Laser Performance’s license to produce the design citing lack of royalty payments, and quality issues with the hulls. Litigation ensued, and in in 2019 Laser performance lost the rights to build official laser hulls. The next year,  Kirby was awarded 6.8 million USD. As Laser perfomance owns the trademark on the laser, the boat is now known as a ILCA 7, ICLA being the International Laser Class Association

Kirby also designed the Sonar, a 23′ keelboat which is the largest boat used in Paralympic competition for three person keelboat event. 

Kirby is a member of the Canadian and American Sailing halls of Fame, and in 2018 was awarded the Order of Canada. He was a member of the Noroton Yacht Club in Connecticut, and Laser #0 is on display at Mystic Seaport in Connecticut.
