One of my favourite educational YouTube channels SciShow recently posted a video on map projections. The video gives a good introduction into why we use map projections and explains how different map projections distort Earth, whether by area, shape or direction. We all know how much hate the Mercator projection gets for how it grossly distorts size, and I enjoyed how the video made note that the Mercator does have its positive aspects: maintaining shape and true direction.
SciShow focuses on the whole world in this video, but map projections are also an everyday consideration when making regional or local maps. You're probably not going to want to use the same projection to plot Russia, which mainly spans east to west, and Chile, which spans north to south.
What's your favourite map projection?
The Vancouver housing market has generated a considerable amount of buzz in recent years due to its ever skyrocketing prices. I came across of mapping and statistics application by Mountain Math that shows the amount of single family homes have been demolished in last 30 years and predicts which homes will be demolished in the 15 or so years.
To me the results are astonishing. 63%!
I really liked the explanation as to why so many building are being demolished:the Relative Building Value or "the percentage of the market value of the property that is attributed to the physical structure of the house." I had an understanding of the "Location, Location, Location" concept but it is shocking to see the percentages graphed out. This concept makes the reasons for tearing down so many houses clear: to build homes where their monetary value better matches the land they are on.
I learned a lot about working with GIS professionally at Frontenac County. It was a privilege to be a part of a great team! I was able to work on a variety of maps and projects, from digitizing zoning maps to taking a geospatial inventory of many of the county's cemeteries.
The county is a great place to enjoy the outdoors. I have many fond memories of hiking the Frontenac Provincial Park and biking along the K&P Trail! If you want to learn more about Frontenac County, check out their online GIS Frontenac Maps.
Working at Loyalist Township gave me one of my first chances to create static maps that the public would use. As of writing this post, they are still up on the Loyalist website!
Looking back, there are definitely cartographic elements I would improve. For example, I would choose a more standard font and I would try to make the colours a little bit brighter. Other than colour, the only symbology change I would make would be to the wetlands layer. A more conventional symbol, like the one shown to the right, would stand out more and help the reader understand what the feature is without having to look at the legend.
On the township wide All Parks map, I would definitely take advantage of the ESRI's Key Numbering labeling method. I wish I had known about it back then!
