  • Optimizing map projection selection for world maps and web maps

    Creator:
    Šavrič, Bojan
    Abstract:
    The selection process for map projections is a mystery to many mapmakers and GIS users. Map projections ought to be selected based on the map’s geographic extent and the required distortion properties, with the goal of minimizing the distortion of the mapped area. Despite some available selection guidelines, the selection...

  • Evaluating the effectiveness of illuminated and shadowed contour lines

    Creator:
    Eynard, James D.
    Abstract:
    Illuminated contour lines, where line width and color are varied based on an angle of illumination, date back to the mid-nineteenth century, but their effectiveness compared to conventional contour lines has not been fully examined. Currently, illuminated contour lines are not widely used in computer-based cartography because they are not...

  • 3D vs. conventional volcanic hazard maps : a user study at Mount Hood

    Creator:
    Preppernau, Charles A.
    Abstract:
    Volcanic hazard maps inform the public on the nature and extent of the hazards that threaten them, but these maps are often challenging for those who are not trained in map use or geology. The maps in this study focus on lahars, a dangerous, fast, and far-reaching volcanic hazard that...

  • Improving the representation of large landforms in analytical relief shading

    Creator:
    Marston, Brooke E.
    Abstract:
    Relief shading is the most common type of cartographic relief representation for print and digital maps. Manual relief shading results in informative and visually pleasing representations of terrain, but it is time consuming and expensive to produce. Current analytical relief shading can be created quickly, but the resulting maps are...

  • Natural-color maps via automated coloring of bivariate grid data

    Creator:
    Darbyshire, Jane E.
    Abstract:
    Natural ground color is useful for reference maps as well as maps where a realistic representation of the Earth's surface matters. Natural color schemes are less likely to be misinterpreted, as opposed to hypsometric color schemes, and are generally preferred by map readers. The creation of natural-color maps was once...

  • Automated Layout of Origin-destination Flow Maps : U.S. County-to-county Migration 2009-2013

    Creator:
    Stephen, Daniel M.
    Abstract:
    Visualizing large movement datasets with flow maps is difficult because overlapping flows create significant graphical conflicts that make accurate interpretation difficult or impossible. Interactive flow mapping applications allow users to explore large movement datasets by automatically generating flow maps from subsets of the data in response to queries by the...

  • Automation and Evaluation of Graduated Dot Maps

    Creator:
    Arnold, Nicholas D.
    Abstract:
    Dot mapping is a traditional method for visualizing quantitative data, but current automateddot mapping techniques are limited. The most common automated method places dotspseudo-randomly within enumeration areas, which can result in overlapping dots and verydense dot clusters for areas with large values. These issues affect users’ ability to estimatevalues. Graduated...

  • Emerging Impacts Resulting from the Implementation of the United States Pacific Coast Groundfish Trawl Rationalization Program

    Creator:
    Thompson, Jenny
    Abstract:
    On January 11, 2011, the Pacific Fishery Management Council (PFMC) instituted a catch share program for the West Coast groundfish trawl fishery. The program was intended to create a more sustainable fishery and increase economic efficiency through the use of individual fishing quotas and fishing cooperatives. While there are extensive...

  • Adaptive Composite Map Projections

    Creator:
    Jenny, Bernhard
    Abstract:
    All major web mapping services use the web Mercator projection. This is a poor choice for maps of the entire globe or areas of the size of continents or larger countries because the Mercator projection shows medium and higher latitudes with extreme areal distortion and provides an erroneous impression of...

  • Comparative analysis of Google Earth versus traditional paper maps in middle school earth science education

    Creator:
    Edstrom, Jillian Aasta
    Abstract:
    As GIS becomes more prominent in academic classrooms at all levels of education, the subject of geography and its related disciplines can be approached with a geospatial technology perspective, using new tools and lesson plans. The implementation of Google Earth in classrooms is just one example of this. Research was...
