Session: Open Source Technology

Karsten Vennemann

The talk gives an overview on building web GIS solutions using open source geospatial software components. A selection of the most advanced and popular open source components and their roles and functionality in an application framework are described. A complete stack for building web GIS solutions may include a client-server application framework, a web mapping engine supporting cartographic rendering functionality and basic GIS capabilities, data storage solutions such as spatial databases, and additional tools extending or enhancing the GIS capabilities of the mapping engine. The concept of an interoperable software solution is illustrated using a variety of examples. Web GIS application frameworks are either complete client-server solutions such as MapFish and Mapbender or Web GIS clients such as Open Layers and Ka-Map. Internet mapping engines such as MapServer and GeoServer render images, provide basic GIS functionality and/or provide the functionality for serving Web mapping services (WMS) and Web feature Services (WFS). Using cached and tiled data in a web GIS application can substantially speed up its response time. TileCache is a server and caching solution that can be used for the creation of cached data from WMS. Feature Server provides data conversion of simple features from a variety of input formats into target formats such as JSON, GML and KML and can be used to integrate the framework with additional applications. Spatial databases include solutions such as PostGIS and MySQL. PostGIS itself provides comprehensive GIS capabilities that can greatly extend the mapping engine’s capabilities and simplify execution of geo-processing tasks using spatial SQL. Additional tools can be integrated with the framework to provide specific GIS capabilities.

The talk describes a web GIS application based on open source geospatial software components that was built for the Obama Campaign during the 2008 US presidential election. The goal of the application was to support the work of campaign field organizers in battleground states for voter targeting and prioritization purposes. Technically the application was hosted on an Amazon EC2 server running an Ubuntu (Linux) operating system, Apache 2 HTTP Server, PHP server side scripting and included three main building blocks of the web GIS: a spatial database (PostGIS), a map rendering engine (MapServer), and a mapping framework which supplies the map viewer (OpenLayers). The initial application was set-up for the state of Indiana as a template and was used as a model to build similar applications for other battleground states to follow. The idea was that all battleground states have their dedicated website and data sources, but share the server applications and GIS components. Data relevant to the Campaign such as voter registration percentages, voter persuasion rates, and vote activities of prior elections were mapped on voting district (precincts) level. In addition information about individual voters and their likely candidate of choice, along with a variety of base layers were published as Web Map Services (WMS) via MapServer. Many of the relevant election data in the PostGIS databases were then updated by the campaign on a daily basis. Spatial data from WMS were then draped over background layers such as Yahoo or Google base maps in the OpenLayers map viewer. The template-oriented approach worked well for the campaign and later was rolled out to about a dozen battleground states. The project illustrates how powerful interoperable OS GIS components can be, even with minimal customization and on a low budget: http://www.geoconnexion.com/uploads/open_sources_18_intv8i3.pdf

The low elevation fothills of the Boise River Wildlife Managment Area provide critical winter habitat for mule deer and elk.  Mule deer from as far away as the Sawtooth Mountains migrate here each fall to avoid the deep snow and extreme cold as higher elevations.  Deer survive winter by using energy reserves (body fat) gained during summer and by minimizing energy expenditure - that's why disturbance from people and pets can be so damaging to deer during winter and early spring.

Idaho Outfitters and Guides Licensing Board licenses specific areas to outfitters. Over 6 years close to 2000 areas for 40 different activities have been digitized. Idaho Fish and Game has produced a number of different maps to assist the board in its decisions about new areas and resolving conflicts which have become apparent now that the area descritions can be seen spatially. This map for use by the US Forest Service shows the areas for Elk and Deer hunting areas and the river segments.  Outfitter license area maps may also be accessed at http://fishandgame.idaho.gov/ifwis/ioglb.

The Northwest Gap Analysis Project (NWGAP) has recently completed a land cover map depicting the distribution of Ecological Systems (ES) across Idaho, Washington, Oregon, Montana, and Wyoming. Developed by NatureServe, ES represent a midscale vegetation classification system designed to be map-able with Landsat 30 meter resolution imagery. Three mapping teams have been involved in mapping the projects 12 map zones; (1) Oregon State University and USDA Forest Serve, (2) Sanborn Solutions, Inc., Portland, Oregon, and (3) NWGAP, Moscow, Idaho. Collectively the 12 zones of the project depict the distribution of one-hundred-seventy-three ES classes and thirty-two land cover and disturbed classes across the Northwest. The NWGAP land cover data have been reviewed by Northwestern vegetation ecologists involved throughout the mapping process. Accuracy rates calculated at the zone level are above 80% for many of the ES. The land cover data are available for download at http://www.gap.uidaho.edu/Northwest/data.htm.

Mitigating Stranding and Trapping Effects on Fish Species During Hydroelectric Operations
Seattle City Light (SCL) is relicensing the operations of the Boundary Hydroelectric Project (Project) on the Pend Oreille River. The Pend Orielle River is located in Northeast Washington and is home to varied and important fish resources. These resources can be negatively affected by receding water levels either from Project operations or from natural reductions of inflow. When these conditions exist, fish may become stranded in shallow sloping shoreline areas (< 4%) or isolated in pools that become disconnected from the mainstem flow.
SCL is funding a study which was designed to develop an index model of relative stranding and trapping effects based on various scenarios of project operations and natural flow patterns.
This poster demonstrates the geoprocessing tools and methods used to identify potential stranding and trapping areas. The areas were periodically examined in the field during water drawdown events to measure actual fish stranding or trapping. Site-specific information, such as substrate and presence of macrophytes (aquatic plants), was also noted. A hydraulic routing model, which was developed separately, was used to determine when areas would be dewatered and the duration of trapping at specific pools. Applying assigned multiplication factors to the analysis, along with the hydraulic routing model, produced the stranding and trapping indices for each scenario. These resulting indices were then available for management personnel and interest groups to examine and compare the relative effect of various operation scenarios on fish stranding and trapping.

Every ten years, since 1790, the United States has conducted a census of its population. Next year, on April 1, 2010, the United States Census Bureau will conduct its 2010 decennial census. Preparation for this effort began long ago with a focus on enhancing partnerships with state and local agencies. Many of these partnership efforts have involved an increase in the use of locally provided GIS data. Lane Council of Governments has been involved in a number of Census programs aimed at utilizing local data and expertise in order to improve Census 2010 results. This poster will describe those programs as well as give examples of how Census data are used at LCOG.

The City of Springfield designed this jam packed map to provide the community and potential developers with as much vital City information as possible in one map. The challenge brought to our GIS department was the need to see about 10 maps on 1 map without losing clarity, information and to maintain feature simplicity and balance. Although the battle was in the details, this cartographic design included elements of generalization, simplification, abstraction, hierarchy and ground relationship, colour and contrast.
The final map product was successful in bringing all City data together with equal importance and straightforwardness giving a large audience an easy to read, robust map of our City.

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.

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.
