Last month we introduced a new GIS & You feature—a (hopefully) monthly contest called Where in King County? This month’s contest is more difficult.
Among the fundamental skills required to be map literate, that is, to be able to read and comprehend maps, are an understanding of scale, the recognition of spatial orientation, and an appreciation of map projections. A higher-level, overarching principle of map literacy is that a single map can seldom tell a whole story, which is a point well made by Dr. Kenneth Field, Esri senior cartographic product engineer, in a recent article in Wired.
You’ve heard about vector tiles. You’ve used vector tiles in a variety of online maps, perhaps without even realizing it. But have you created your own vector tile maps?
The Seattle Times on Saturday, June 2, published an article by staff reporter Erik Lacitis about a “secret, massive program that produced a million maps of cities and places around the world.” The mapping program is fascinating both from a cartographic perspective and a local perspective since Seattle and its environs are among the parts of the United States that were mapped.
One of the most satisfying things that a well-made map can do is convey a sense of place. And an especially well-map map may convey a sense of a past place that both infuses and transcends a present location. I came across such a map yesterday just a few blocks from our own King County GIS Center location, where Seattle’s Pioneer Square transitions to the International District, specifically the historic Japantown.
The King County Prosecuting Attorney’s Office (PAO) is a recurring client of King County GIS Center Client Services. Often the PAO needs our help creating exhibits for court or with analyzing GPS data to develop a case.
Government leaders inevitably leave long paper trails and numerous digital footprints. One of the newest marks made by our own current King County Executive, Dow Constantine, honors his first predecessor in his office, Gov. John Spellman who died on Tuesday. Remembrances of Gov. Spellman this week prompted me to reach back into my personal archives for a record of when then County Executive Spellman’s paper trail and my much more humble one intersected.
An effective map portrays a place, delivers a message, or reveals a pattern with representational accuracy and visual clarity. How to make that happen is the subject of this workshop, a mix of lecture and exercises which gives GIS practitioners the practical information and techniques needed to create effective, successful maps in any display medium.
The re-use and re-purposing of map elements, especially digital map data, may seem simple and obvious since we are far past the time when the availability and use of digital data and production practices became the norm in cartography. But it hasn’t been all that long since the time when mapmakers were beholden to the technical strictures imposed by mechanical map construction methods.
King County Archives recently made 45 volumes of the King County Assessor’s timber cruise reports from 1907-1908 available on their website.
