Torontonian Map of Toronto

Next week the GIS-Pro conference opens in Toronto. To help people navigate their way to and around the area, here is a map from the locals.

Judging from this zoomed in view of the area, you can now take the subway all the way to Lake Simcoe for some weekend foliage viewing. It's also helpful that they built a diagonal road from NYC to Buffalo.
Also, they move the British Isles much closer for your convenience.
Hope this map helps you enjoy your stay!

Women in Cartography

Women in Cartography is an excellent exhibition at the Boston Public Library. It runs until March 27th. If you don't get a chance to visit in person you can view the exhibition online here. In December I got a chance to see it. Here are some of the highlights.

Physiographic Diagram of the Western Pacific Ocean - Marie Tharp and Bruce Heezen, 1971
Geologist/Cartographer Marie Tharp created the first map of the ocean floor. Originally this map was credited solely to Heezen, her research partner. It is displayed on the floor. Here is a picture I took looking down.
The numbers indicate depths of the sea bottom and height of undersea mountains. The colored areas are land, in this case the Hawaiian Islands rising from the depths of the Pacific.

Mappemonde Projetée sur l’Horizon d’Angers - Céleste Babin, 1839
This double hemisphere map was done by a student in Angers, France. The left hemisphere is centered on Angers and the right one on its antipode (opposite side of the earth.)

The detail below shows off some nice hand calligraphy and a view from Angers.
A General Map of North America …  - Mary Ann Rocque, 1761
Rocque carried on her husband's business after his death. This map was credited to "M.A. Rocque" obscuring (possibly intentionally) that it was produced by a woman.

A New Map of ye Seat of War in Italy - Ann Lea and Robert Morden, 1701
Ann Lea also took over her husband's map business after his death. The map shows areas of northern Italy that were fought over between France and the Austrian Empire before Italian unification.

“Nationalities Map No. 1,” from Hull-House Maps and Papers … - Agnes Sinclair Holbrook, 1895
http://maps.bpl.org/id/19878
Hull House was a settlement house for female immigrants in Chicago. Holbrook, a house resident designed the map based on Charles Booth's income maps of London (previously mentioned in this post about my visit to Chicago's Newberry Library.) Other house residents helped her gather data for the neighborhood.
The Attack on Bunker Hill in the Peninsula of Charlestown the 17th of June 1775 - Mildred Giddings Burrage, 1926 
Burrage was a Maine-based artist. She created this map/scene using layers of Gesso to build up a sense of topography.

The exhibit concludes with a technology section including the following maps.

Lower East Ride: Adapting to Change - Maryam Khabazi, Designer, 2013
Created by Green Map NYC, this map highlights the impact of climate change and natural disasters such as Superstorm Sandy and shows resources to reduce energy consumption.

Making History - GIS and Women - Linda Loubert, PhD - 2014-
Dr. Loubert built this crowd-sourced webmap to document thousands of women working in the field of GIS.

You can see the entire online map here or by clicking the image above. I know some of these people! GIS women rock!

R.I.P. Roger Tomlinson

Roger Tomlinson, the "Father of GIS" passed away last week. He developed the Canada Geographic Information System, the world's first computerized GIS.
http://www.gislounge.com/roger-tomlinson-father-gis-died/
Working as a government consultant for Canada in the early 1960's, he was asked to find a location for planting trees in Kenya to feed a paper mill. The location needed a suitable slope, appropriate weather conditions, and access to transportation. The location would need to be free of monkeys, which eat young trees, and away from elephant migration routes. The creation and manual overlay of this many maps made the labor cost too high for the client. Tomlinson began to think about how to put these maps on a computer and generate numbers to measure land suitability.

He brought this idea to several computer companies but they were not interested. In 1962 he met Lee Pratt, head of the Canada Land Inventory, on an airplane. Pratt was looking to generate land use maps for the country to determine suitable areas for agriculture, forestry and wildlife over a million-plus square mile area. Tomlinson published a feasibility study for computerizing overlays and was subsequently asked to join the government in developing its Geographic Information System.
Printed maps from the Canada Land Survey can be accessed online at the Canadian Soil Information Service. The map above is of forestry capability in British Columbia. The green areas (in this case the lowlands) have the most capability while the oranges and pinks are less suitable. Below is a 1967 agricultural soil capability map for the area around Ottawa, where the map was produced. Orange areas are the best, green areas have severe limitations and pink areas are unsuitable.   

Much of the information above came from Putting Canada on the Map by Lynn Greiner, published in the Globe and Mail.

What I do for a Living-Part 1

Things are really busy for me this week. We have a big infrastructure evaluation project that I need to map and analyze every which way. Since I don't really have the time for an interesting, well researched post, here are some storm drainage pipes somewhere in Massachusetts. This is what I do in my non-spare time.
