This map shows the extent of LiDAR coverage for the Willapa Bay Intertidal Area, placed over 2008 one-foot orthophotography. Oyster growing areas such as oyster beds, oyster bed leases, oyster farms, and oyster reserves are labelled and displayed. The map also shows intertidal areas, prohibited commercial shellfish growing areas, as well as recreational shellfish beaches. Additionally, the locations of oyster and other seafood processing facilities are displayed. The map also includes a brief description of the physical environment of Willapa Bay, the history of the bay's oyster industry, and relates the importance of private stewardship towards maintaining this vital Pacific County industry.

For the past 8 years, the 5th Street Cemetery Necrogeographical Study has sought to combine and model the “best practices” of several associated disciplines and apply these methodologies to timely issues of local import. Every community has its intriguing historical questions that can benefit from but actually transcend a paper-and-pencil approach. These questions are appropriate practicum situations for inquisitive students, who can be empowered with mastery investigative skills and the appropriate technologies to unravel local conundrums and enhance the community’s understanding of itself. We have learned that the truth may be more interesting than any fiction. And the total truth is rarely seen through only one glass.

Belying their tranquility, cemeteries harbor several contagions. Nineteenth century embalming methods are especially problematic. Undertakers routinely used an arsenic trioxide solution in large doses to control bacteria and postpone putrefaction. Some recipes recommended up to 12 pounds per corpse. However, it killed many practitioners and was banned by 1910. Arsenic sickens by allosteric inhibition. Essential metabolic enzymes are blocked, and the victim suffers multi-system organ failure. Mortician health improved, but the effects of arsenic pollution in old graveyards have only lately received attention. This poster reports and explores the findings of two teams of junior and senior high school students in Lewiston ID.

Session: Mobile GIS, GPS & Asset Management

Arnab Bhowmick, GISP, LEED (Program Manager, Weston Solutions Inc., Seattle)

Mobile applications are fast becoming a significant part of the enterprise in many organizations where field operations play a vital role. Some departments and industry verticals e.g. first responders, public works, asset management, transportation, telecom, gas and utilities, natural resources, event/ crisis management etc. are using or intend to use mobile GIS for their regular business operations. Weston is involved in various mobile GIS opportunities and has been helping the City of Renton recently to roll out their Enterprise Asset Management. After the initial deployment, the City intends to extend GIS application for asset management to the field crew. The City is using ArcGIS Server Mobile as the platform for mobile GIS. Weston is working with the City to help them achieve their GIS and overall strategic goals for the enterprise.

Session: GIS Implementation & Management

Arnab Bhowmick, GISP, LEED (Program Manager, Weston Solutions Inc., Seattle)

GIS has evolved to become more and more an integral part of the enterprise operations in any business. Service Oriented Architecture (SOA) is becoming a popular choice as deployment architecture. Various departments within an organization typically use or try to use the SOA to access services, data and applications to conduct their business. GIS and other services are being deployed and consumed to address business goals and routine operations. Moreover, there are legacy data support techniques, and data dissemination processes that makes an enterprise implementation seamless and sensible. Weston has been involved as a “Trusted Integrator” on many such enterprise GIS integration projects and would like to discuss some related case studies. Some challenges always present themselves during any enterprise implementation. But there are some key traits and steps for a successful enterprise implementation. Weston would like to cover those as well during the presentation.

Cadastral Editor is an extension to ArcGIS and has largely simplified the complex survey data management process. The primary objective of cadastre data conversion is to develop and maintain basemap layers with high degree of spatial accuracy. Controls such as ground survey points, GPS or RTK points and aerial photography are used to enhance accuracy of cadastre fabrics with time. It stores all legacy records and maps as historical layers including metadata information. Least Square Adjustment (LSA) method is used to adjust the fabrics to enhance spatial accuracy. As new data comes in, the cadastre fabric can adjust and update thus increasing the accuracy with time. Weston has successfully deployed this tool at the City of Encinitas, CA and was awarded the “Special Achievement in GIS Award” by ESRI in 2008 for the implementation. The City is managing their cadastre using these tools now with higher efficiency and effectiveness.

Session: Advances in Cartography

Ken Kato

Designing and producing maps and graphics that communicate well is challenging. We here often from GIS users that they are rarely afforded the time they wish for map design. Ken will present his ‘Top 10’ cartographic design considerations that the lab employs regularly, whether the project has several months available for design or several minutes. Examples from several of the Lab’s completed and on-going projects will be presented to illustrate cartographic design principles, methods, and work-flow strategies that have been successfully applied in the UO InfoGraphics Lab.

Session: GeoVisualization/3D GIS

Doug Smith, P.E., C.P., R.P.P.

We thought we had our pixels in a row. But now that we all understand how to plan for, acquire and use film based aerial mapping products (such as orthophotography, planimetrics and contours) all of the rules have changed. Well, not all of the rules, but a fair number of them. This presentation will provide a brief overview of how newer photogrammetric mapping technologies, including digital cameras and LiDAR, impact the planning and procurement process for digital image and topographic mapping projects. The emphasis will be on key project design parameters that affect accuracy, resolution and suitability for intended applications and how these compare with what was attained from conventional film based aerial mapping approaches. This discussion is targeted to GIS users and project coordinators and is focused on the “big picture” issues and planning considerations for new technologies, not on technical or flight planning considerations. Questions and dialogue are encouraged.

Session: GIS in Education

Lynn Songer, Eric Sproles

Historic barriers to wide-spread use of GIS in the classroom are being lifted as educators embrace the power of Web-based GIS and other Internet based geospatial technologies. Two NSF-funded projects at Lane Community College in Eugene, Oregon - MAPS-GIS (Mapping Analyzing and Problem Solving with GIS) for college level students and GEOSTAC (Geospatial Teaching Across the Curriculum) for high school teachers – will be discussed. We will illustrate how Web-based GIS is being embedded across the curriculum and how it is being used to teach important geospatial concepts and skills and educate students about GIS classes and careers.
