We prepared a series of maps to support the application for a collection of Frank Lloyd Wright buildings across the United States as UNESCO World Heritage Sites through the National Park Service. The project was a challenge because sites were geographically dispersed and varied in size. Base data required for large scale mapping varied widely in av...

Visual contrast is a fundamental principle employed in cartographic design to highlight foreground elements on maps. However, limited software resources and research exist on how to maintain consistent visual contrast and hierarchy relations across map scales. This task is especially challenging in map series that are constrained by a color and lay...

Rivers were among the first geographical features in the United States (U.S.) to receive official names, often initially stemming from Native American heritage. Today river titles portray both cultural and physical origins. These naming conventions provide a descriptive connotation driven by social perceptions. At present, most people accept that t...

There continues to be a surge in experiments and user studies conducted on online crowdsourcing and micro-task platforms within the domain of cartography and geovisualization. At the surface, online user studies, through services such as Qualtrics together with Amazon Mechanical Turk (MTurk), seemingly offer researchers dynamic ways to test visual...

The near ubiquity of maps has created a population the is well adept at reading and understanding maps. But, while maps are familiar, understanding how the human brain processes that information is less known. Discussing the processing of geographic phenomena could take different avenues: specific geospatial thinking skills, general perception and...

Cartographers assert that, as a core tenet of effective design, effective implementation of visual contrast is crucial for map reading. It is theorized that without sufficient contrast, readers are hindered from efficiently accessing the underlying spatial information. Yet this essential task of practically implementing effective visual contrast is...

Cartographers assert that visual contrast is vital for guiding attention and enabling effective map communication. Without perceptual clarity in design, the process of cognizing the underlying spatial information is obstructed. However, research in neuroscience has labeled visual contrast processes such as Gestalt figure-ground as wholly pre-attent...

Cartographers have been representing places and scenes for thousands of years. We know that there is not one single way to represent place. We can use a reference map, thematic map (not to mention all the different types), large scale, small scale, oblique and overhead remotely sensed image, hand-drawn cartoon maps, street view photographs, animate...

As cartographers, we contend that visual contrast is crucial to establishing perceptual differences that allow the reader to distinguish features on a map. Yet the central task of determining the most optimal configuration of visual contrast continues to seemingly elude us. Additionally, much of the theoretical underpinning of our understanding of...

There has been considerable development in the automotive GIS sector, largely been driven by the technological progress towards autonomous vehicle functions. Traditional automakers are beginning to collect extensive GIS data while traditional GIS data providers are focusing more on automotive technologies. A prime example of this alignment is the B...

In order to develop sustainable biofuel production pathways, energy policy makers, fuel producers, and land-owners require knowledge about the spatial distribution and supply-cost of prospective resources. The methods and analysis presented in this poster aim to improve spatial decision-support in the biofuel sector, with particular emphasis on reg...

The Pennsylvania Department of Transportation records all reported vehicle collisions that occur within the city of Philadelphia. Each collision contains a spatial reference point and many attributes referring to the cause, type, severity, time, etc. of the collision. The Philly Crash Atlas turns these many data points into a useful visualization f...
