  • Session: Mobile GIS for the Enterprise

    Frank Roberts

    ESRI products can provide decision-makers and field staff with mobile applications that allow for display, query, and editing of geospatial data. By creating tailored solutions for end users and putting these applications on mobile devices such as smartphones and tablets, GIS developers can make spatial data more accessible than ever before. However, choosing the best mobile platform can be confusing. Innovate has worked with a number of clients over the past year to enable a wide variety of end users to access data via Droid Phones, iPhones, iPads, GPS devices, laptops and desktops. Each of these pieces of hardware has specific needs and limitations for GIS data to be effectively used on them. In addition, there are limitations on the use of data between these devices, so pairing the correct devices is critical for a successful implementation of this technology. This presentation will demonstrate a variety of use cases of mobile and web based technology. We will cover both our lessons learned and our success stories with these technologies.

    ODOT lacked current location and condition information on thousands of culverts around the state and thus embarked on a statewide effort to update this inventory. Key parts of the effort has been an initial triage with follow-up condition assessments using two related applications for mobile GPS equipment. This coordinated effort ensured that data could be quickly and appropriately collected according to standards, attributes and definitions that would allow a statewide dataset to be updated for decision making for repair and replacement. This has been a multi-step effort to evolve a process into compliance with an ODOT enterprise standard. We have taken a holistic approach to development of this GPS solution as part of an effort to ensure that the data was returned to the source system.

    Remote Sensing technologies in the Wildland-Urban Interface (WUI) have shown promise for use in post-fire WUI assessments, derivation of WUI fire model inputs and pre-fire WUI assessments. Remote sensing is an important technology for post-fire WUI assessments and can fill in many data gaps in assessment of the WUI fire disturbance continuum. Point cloud data from Light Intensity Detection and Ranging (LIDAR) and color imagery have shown promise for deriving WUI fire model inputs and remote sensing derived 30 meter spatial resolution wildland fire model inputs have been created for most of the United States. Finally, most pre-fire assessments utilize some form of remote sensing technologies, to a lesser or greater extent. However, validation of the use of this data for WUI assessments is in its infancy. Nonetheless, remote sensing technologies have proven useful in post-fire assessment of WUI fire damaged communities. There are various techniques that can be utilized for identifying important elements in ground, nadir and oblique WUI post-fire imagery. These techniques include aerial photo interpretation and fusion of LIDAR and pre- and post-fire color infrared imagery. The use of a GIS based tool for integration of remote sensing data in the creation of WUI fire model simulations will also be demonstrated to qualitatively examine empirical fire model outputs produced from different resolution data. In all cases the need for accompanying ground assessments has been demonstrated. Consequently, an initial framework for the integration of field data collection with remote sensing for complete assessment of the WUI fire disturbance continuum will be detailed. This work is being conducted by Geospatial Measurement Solutions under a Fire Research Grant from the National Institute of Standards and Technology (NIST) and specifically focused on achieving objectives of the Fire Risk Reduction in Communities Program.

    Stream networks in western Washington are extensive and their associated riparian management zones represent a considerable portion of the land base. Accurate mapping of stream networks is important for effective and efficient forest land management, environmental assessments, and forest land planning. Current statewide stream mapping systems suffer from a variety of well-known errors, such as inconsistent mapping scale, errors of omission, and incorrect stream typing. We present a summary of our efforts to develop a synthetic, typed stream network using field observations, LiDAR-based digital terrain models, and a statistical technique known as binary logistic regression. We describe our methodology for model construction and present preliminary results. Our efforts indicate that a LiDAR-based synthetic stream layer is generally superior to current stream mapping systems, and could be used to build accurate estimates of the location and extent of the stream network and its associated riparian management zone in western Washington.

    The Joint Water Commission (JWC) is a collective water supply agency and a primary drinking water supplier in Washington County, Oregon. The JWC’s 228 square mile watershed includes portions of the Tualatin River and Trask River basins. One of the main goals of the JWC’s source water protection efforts is to safeguard drinking water quality by evaluating potential contamination risks within the JWC’s watershed and participating in programs to minimize those risks. The JWC selected GSI Water Solutions to build a source water protection-specific geodatabase and perform specific GIS analysis that would help to quantify potential contamination risks and sensitivity of lands to contamination. GSI was tasked with gathering up-to-date GIS data from various sources that would help to model risk and sensitivity. Once the GIS data was imported into the geodatabase, a risk analysis and a sensitivity analysis were performed. The risk analysis incorporated GIS data related to pesticide applications, agricultural fertilizer applications, potential hazardous contaminant sources, septic tank locations, areas of urban development, and proximity to public roads and railroads. The sensitivity analysis incorporated GIS data related to flood zones, forestry activities, surface water time of travel zones, unstable/vulnerable soils, wetlands, and proximity to surface water. While each of the GIS data used in the risk and sensitivity analysis were informative individually, additional insights about overall risk/sensitivity within the JWC watershed was found by combining the GIS data using the weighted sum geoprocessing method. To accomplish this, GSI worked with the JWC to determine numeric risk/sensitivity rankings and weights of significance to the overall analysis for each layer. Once the rankings and weights determined, GSI used the weighted sum geoprocessing tool in Spatial Analyst to combine the layers to create an integrated, comprehensive view of both risk and sensitivity of lands within the JWC’s watershed. The output of the risk and sensitivity analysis quantified the susceptibility of any location within the JWC’s watershed to contamination based on multiple layers of input. Once watershed susceptibility was quantified, the JWC can better focus program development (saving time and money) to minimize the potential impacts from chemical or biological pollutants.

    Conservation of biodiversity relies on having spatial data, such as predictive species distribution models and protected areas layers, that can inform conservation prioritization across the US. Nationwide species distribution models for amphibians, birds, mammals, and reptiles are currently being developed, using a standardized and consistent methodology. We have begun a national biodiversity assessment that identifies how much of each species’ distribution occurs on lands managed for biodiversity and what agencies manage those lands, based on USGS-GAP’s Protected Areas Database of the US (PAD-US). Land managers, researchers, decision makers, and the general public can use this information to evaluate the efficacy of conservation strategies or to identify critical habitat. We maintain a database that can provide these data for each species by state, county, and Landscape Conservation Cooperative (LCC). These data will help to prioritize conservation efforts in the US by providing landscape-scale assessments of biodiversity.

    Military munitions and related constituents on both active and retired installations represent a principal environmental, health, and safety issue on millions of acres of public and formerly publicly owned land. Due to the large cost associated with traditional "Mag and Flag" Ordnance and Disposal operations, technologies such as LiDAR and Orthophotography, Digital Geophysical Mapping (Helicopter and Ground based), X-Ray Fluorescence, and Synthetic Aperture Radar are utilized. Mr. Hille will discuss the central role the GIS plays in the management, deployment, and implementation of these technologies to provide for a cleaner safer environment.

    Session: Open Source Technology

    Allan Laframboise

    As many of us know, GitHub has become the largest and most popular open source, social coding platform in the world. Not only does GitHub provide developers with a simple and effective way to publish projects and to collaborate with other developers, it also gives organizations a way to deploy large software development projects in the same space. Organizations can publish projects and interface with the community through the standard “Fork, Clone, Pull Request” methodology to accept code changes back into projects. Internal teams at large organizations can also use the private features of GitHub to curate and further develop projects until they are ready to be moved the public domain. Esri hosts over 80 public code repositories on GitHub. These “geo projects” extend across a very wide-range of disciplines and technologies. This includes everything from full client-server Government solutions to specific geo-utility/analysis tools to ArcGIS products, components and solutions. Here are a few examples: - Geoportal Server - a standards-based tool that enables the discovery of geospatial resources and data; - Citizen Service Request Solution - a client-server application allowing citizens to submit requests from their desktop, mobile and tablet devices; - Spatial Framework for Hadoop - a spatial framework that allows developers and scientists to use the Hadoop data processing system for spatial data analysis; - Bootstrap for Maps – an example of how to use Bootstrap with Dojo to build mapping apps; - ArcGIS Flex Viewer - the complete Flex source code for building RIA web applications. This session covers how Esri embraced GitHub for sharing geo projects both across the organization and to the public domain, the implementation strategy, the technical challenges faced, and why others might want to consider adopting GitHub for their organizations as well.

    Address information is the basis of most government transactions and services – to provide emergency response and social services, to request tax and utility payments, to analyze and permit regulated activities, and for planning and resource management activities. Portraying address locations accurately and consistently statewide in relation to other features on a map is essential to the efficient provision of government services…and from a public safety perspective, will save lives.

    A centralized, web-accessible repository of address point locations, that is built and maintained at the local level by official address authorities, will decrease the effort and cost required for government agencies to interact with Oregon citizens and businesses.

    Session: Poster

    With sea-level projected to rise up to one meter in the next century, understanding the history of sea level rise is of great interest. This project identified a low-stand occurring during the last glacial period ~14,000 years ago. A historic shoreline was observed at 93 meters in depth offshore of Vancouver Island using a Konsberg EM302 multibeam echosounder onboard the R/V Thomas Thompson on 27 January 2013. The multibeam soundings along the transect line from the current shoreline to this historic low-stand were post-processed in CARIS HIPS 7.1 to produce a bathymetric base surfaces at a spatial resolution of 10 meters. Slope variation along the transect line was derived using ArcGis 10.1 and changes in slope of greater than 5˚ were highlighted as potential regions of subsequent historic shorelines. The variation in slope along a survey transect from a depth of 143 meters to 83 meters shows evidence of changes in the processes related to shoreline development. This method of identifying historical shorelines using slope variation from ArcGIS 10.1 confirms previous work identifying low-stands during past glaciation periods and offers insight into measures of historic sea level rise. Identifying historic shorelines via slope variation and using them to observe sea level rise can aid in the understanding of future sea level rise.

    The use of Geographic Information Systems (GIS) in the assessment of a wildfire damaged or destroyed community has many advantages for efficient collection, storage and dissemination of data. The National Institute of Standards and Technology (NIST) and the United States Forest Service (USFS) have developed a tiered WUI assessment methodology (WUI 0-2) for post-fire assessments of the WUI. This methodology is implemented in a GIS based framework, providing for the integration of various technologies for collecting, integrating and analyzing post-fire WUI environments. WUI 2 assessments are complete studies of all aspects of the fire disturbance continuum including defensive actions, exposure and fire timeline. WUI 0 or WUI 1 is a less data intensive post-fire assessment. A WUI 0 or WUI 1 assessment is typically conducted by local authorities at all WUI events that contain damage to the built environment. The goal of the NIST WUI 0 and WUI 1 implementations is to standardize WUI damage assessments to create a data set of structure damage allowing for consistent and repeatable analysis of the WUI across large geographic regions. This poster will give an overview of the NIST WUI assessment methodology and GIS architecture used to store data. Additionally, a WUI 0 and WUI 1 mobile field data collection system for iOS and Android operating systems will be presented. Application functionality for mapping, integrating, and analyzing post-fire WUI data on damage and destruction to the built environment will be detailed. A brief overview of the ArcPad™ WUI 2 application will also be provided. Implementations of this system for collecting WUI 0 and WUI 1 data will be described and opportunities for collaboration will presented.
