The December updates to the ArcGIS Online basemaps are described with a unique Christmas twist. Sit back, pour yourself some egg nog and enjoy the sleigh ride of updates... presented in rhyme!
(With apologies to Clement Clarke Moore)
‘Twas the week before Christmas, when all through our map, No content was stirring, not a long or a lat; The apps were sitting by the server with care, In hopes that an update would one day be there;
When out on the Web there arose such a clatter, I sprang from my desk to see what was the matter. Away to my laptop I flew like a flash, Looked at my browser and cleared out my cache.
Old basemap (left) versus new version (right) in New Brunswick that are now published to the World Topographic Basemap. Changes include new property lines, improved roads, contours, water features and buildings.
The maps that my team tends to with care, Gives the lustre of insight for all folks to share. When what to my wandering eyes did I see, But a gift of new content from eight communities,
Previous map (left) compared to the updated version (right) in Thunder Bay, ON: better buildings, roads, contours and water features.
Old (left) versus new (right) in Wood Buffalo, AB: new roads, buildings and contours added to the map.
Old (left) versus new (right) in Milton, ON: new trails, buildings and parks, along with improved contours and water features.
As leaves that before the wild hurricane fly, When they meet with an obstacle, mount to the sky; Onto the basemaps the updates they flew, With a sleigh full of imagery and content so new—
Sharpening the picture in Pontiac, QC. 50 cm imagery from 2009/2010 now replaced with 30 cm imagery from 2011.
And then, in a twinkling, I saw on the map, The whirring and clicking of each online app. As I drew in my head, and was turning around; I looked at the screen and could not even frown.
I can see clearly now: Beaupré, QC - 50 cm imagery from 2010 (left) now replaced with 15 cm imagery from 2013 (right).
The improvements to content from 1k to small, Were better than I could ever recall. The imagery was fine, so fantastic to see; Things were made large that before had been wee.
Highway 1 and 160 St. in Surrey, BC - 40 cm imagery from 2010 (above); 10 cm imagery from 2013 below.
With some at a scale of 282 The resolution on these was entirely new! With such content and scales available to each, This cross-country update was truly a peach.
Yonge-Dundas Square in Toronto, ON at 1:282, 8 cm imagery from 2014.
In a blink of an eye and a clear of the cache, The maps they did change as quick as a flash. The updates said nothing and went straight to work, And filled all the apps and then said with a smirk,
“We’ll return with more content to add to your maps, With another great update—even better perhaps.” So now I exclaim, ere we forget this great sight— “Happy Christmas to all, and to all a good night!”
