Every time an election occurs, maps become a key component in telling the story, but what type of map best tells the story of the winners and losers? Red/blue choropleths? Areas shaded in an array of purples? Value by alpha maps? Dot density by County? Ultimately, the areas used (e.g. Counties) are arbitrary, exhaust space and dictate the visual pattern we see. We can warp them into cartograms but these sometimes distort geography too much for them to make much sense. The patterns we see are as much a product of the boundaries as the voting patterns of real people in real places. This blog entry explores different ways to map election results and describes a different type of map we made to show the 2012 Presidential election results…it’s a multiscale dasymetric dot density web map (viewable on ArcGIS Online).
With ArcGIS Online, individuals, governments, and organizations alike can create and share compelling map stories. For example, by using just two map layers, law enforcement officials could use ArcGIS Online to determine the locations where crimes are occurring, perform spatial … Continue reading
In his recent blog entry Adding tile layers to your web map, Chris Whitmore explained how the March 2013 enhancement to ArcGIS Online supported the addition of a range of new file types to web maps. Chris described the approach of adding tile layers to web maps which allows you to use web-accessible map tiles from a server directly using a URL request from the browser. In this blog entry I show you how this approach can be used to integrate Stamen and MapBox tilesets in your ArcGIS Online web maps.
Today’s technology has made it easier than ever to effectively share global information with the world. This information can be shared in a variety of ways, including web browsers, mobile devices, and desktop viewers. The Community Maps Team and ArcGIS Online encourage the creation and sharing of content. While sharing content is important, how we share this content may be even more important. Content and information is seldom useful if it is not well crafted and presented clearly. Below are some tips on how one can add value to shared content, ensuring that web maps and apps are engaging and contain the appropriate supporting information.
For centuries, maps have been telling stories—chronicling discovery and conquest, documenting an understanding of the patterns and interrelationships that underlie human and natural systems. But only in the past few years have new technologies and new media vastly expanded the potential of maps to weave narratives. Continue reading
All contributors to the Community Maps Program have a geographical extent associated with their account. This polygon boundary is used to define the extent of data provided to the program. We refer to this as the contribution extent. The program currently supports one contribution extent per contributor, with plans to support multiple extents per contributor in the future.
