Title: Walkability Analysis of Harris County Parks

Abstract: Parks are a highly visible element of county government.  The ability of citizens to access the parks
is of obvious importance.  Walking distance to parks is perhaps the best method to determine park
accessibility.  This analysis determines areas within one mile of a park.  One mile represents the
maximum distance a person would consider walking to a park.  Of course, any distance can represent
the maximum limit of walkability and the analysis adjusted.

Title: Assessing US Land Use Impact by Clean Vehicle Systems

Abstract: Transition of the current gasoline-based transportation system into a renewable fuel-based clean vehicle system can offer great opportunities to reduce greenhouse gas emissions and improve energy independency. However, different transportation fuels have significantly different demands on land resources.
To enable comparison of land demand among different fuel choices for clean vehicles, this research aims to provide an assessment of land demand based on a vehicle mile traveled basis. We analyzed and compared potential renewable fuels including biofuels produced from different natural feedstock (corn, highland switchgrass, lowland switchgrass and open ponds grown algae), and electricity produced from engineering renewable sources (wind, solar, and closed system algae). Optimal choice maps of best natural stock and renewable energy are created from the comparison results. Sensitivity analysis is also used to analyze how sensitive the natural feedstock is to the annual yield changes and the engineering renewable source is to engineering production changes.

3rd Place Winner  Title: Increasing River Flooding Situational Awareness: A GIS Extent Mapping Approach

Abstract:Situational awareness of river flooding and its time evolution through the use of flood extent mapping is critical for emergency management resource allocation, decision making, and overall public alertness. However, current National Weather Service (NWS) mapping efforts for flood extents per gauge site can equate to $10,000-50,000 and six months to two years of resource expenditures before finalization. To offset these high costs, an experimental GIS method for deriving river flood extents has been developed in partnership with the Corps of Engineers. Through a GIS protocol and the use of the Flood Estimation Simulation Model (FESM), early results indicate near 70-95% accuracy and completion times in a matter of days, if not hours. Strong spatial correlations using the kappa coefficient statistic show quality controlled flood extents to have substantial to near perfect agreement with NWS standards (0.70 – 0.99). This technique has already saved resources in an operational setting, and through the use of dynamic web maps, has increased internal and NWS core partner situational awareness during river flooding episodes.

Title:The J(o)urney to Boston

Abstract:This map poster is the culmination of a journey that started two years ago.  For either professional or personal reasons, I have traveled from Oklahoma to various parts of the United States and enjoyed a series of running adventures.  In October 2013, I happened to qualify for the Boston Marathon in Portland, Oregon.  With a Garmin on my wrist, the maps of my paths have been preserved to the delight of this professional geographer/ hobbyist runner/working wife and mother.  The point paths have been converted into shapefiles (online GPX to SHP tool) and then converted to lines (ArcToolbox).  The map layout was created in ArcMap and the background imagery is courtesy of ArcGIS Online resources. 
This map poster shows how recreational activities can be integrated into ArcGIS and the map layout capabilities of ArcMap.  It also celebrates my last stretch of the Joy in the J(o)urney.   #boston2015

Title: Spatial Analysis of Opioid Mortality and EMS Administration of Naloxone in Oklahoma

ABSTRACT: Objective: Identify high-risk areas of opiate overdose using GIS to compare opiate-related overdose mortality data and EMS naloxone administration data.
Background:
On 06/14/2014 House Bill 1782 took effect providing statutory revisions to Administration of opiate antagonists (§ 63-1-2506.1) allowing all first responders to administer naloxone.
Methodology: Patient-level data from the Oklahoma EMS Information System and vital statistics death data were used in conjunction with GIS techniques and spatial scan statistics to generate risk maps for areas with lower-than-expected naloxone use.
Results:Between 01/01/2011 and 06/03/2014, 13,064 instances of naloxone administration were reported. Four clusters of statistically significant, higher-than-expected naloxone administration were identified (1.01<RR<9.0, P=.001). Analysis revealed 19 clusters of lower-than-expected naloxone administration. The clusters of lower-than-expected usage correlated with basic and intermediate licensed EMS agencies. 
Conclusion:Analysis of spatial risk distribution may be useful identifying EMS agencies that would benefit from the Naloxone Training and Administration for EMS Personnel Program.

Title:  When the World Breaks: A Solution for the Broken Data Source Dilemma

Abstract: ArcGIS Map Documents and Layer Files store path references to data sources. When these data sources are modified – moved, renamed, or even deleted – the connection to this file is broken. Although ArcGIS itself offers resources for fixing this issue, they can often be tedious and time-consuming. One solution that has been found to properly heal broken data sources in a timely manner is that of simply reclassifying it. Reclassifying path references using a remap file opens the way for not only altering the data source, but also for updating your workspace from one format to another and replacing or removing a layer from a map document.

Title: Mapping Hunger and Hope

Abstract: Food Insecurity and Food Deserts are widely used to gauge food deficiency. The USDA describes food insecurity as “consistent access to adequate food is limited by lack of money and other resources at times during the year”. The USDA defines Food Deserts as “parts of geographic areas vapid of fresh fruit, vegetables, and other healthful whole foods, usually found in impoverished areas.” Food Deserts contribute to food insecurity and exist mostly in rural and low-income communities. Research finds that population in Food Deserts suffer from diet-related health outcomes. Community Food Pantries mission is to serve local residents who suffer from hunger and food insecurity. This poster displays Food Insecurity and Food Deserts, overlaid with food pantry locations, in Eastern Oklahoma with a closer look at Tulsa County.

Title: “Bell County Veterans: Who, What, When, Where, Why, & How

Abstract: Bell County is filled with veterans. Some areas of the county are home to veteran populations as high as 50%. Both Bell County and Texas have made this area an excellent home for veterans. The country, state, cities, and county provide an overwhelming amount of services to veterans. Locating these services and understanding all the rules are even more overwhelming. This map is shows veterans what their benefits are. Who the benefits apply to. When they can access those benefits. Where to get those benefits. All together this map is a how to for veterans in Bell County. This map will also examine the veteran population of Bell County. Taking into account gender, education, employment, and even disability.

1st Place Winner  Title: Collin County Tollway Corridor Valuation 2001 - 2015 -

Abstract: Will a proposed tollway increase nearby land values in years to come? Let’s see what the past tells us.This study utilizes historical parcel data and compares the values of different tollway segments. A half mile buffer was created from the centerline of designated tollway segments. Then, the parcels with their center in each buffer were selected. The market valuation of these parcels was summed and the value per tollway mile is shown for the years 2001, 2005, 2010 and 2015. The study makes the case that the expense of building the future Outer Loop Toll Road is supported by the future increase in adjacent land values which would recompense Collin County’s construction outlay with potential increased tax revenue.

2nd Place Winner  Title: Plano Paddle Trail Planning Committee – Using ArcGIS Online to Coordinate Data Collection

Abstract: Plano, Texas is a city in the Dallas/Fort Worth area and has numerous parks that contain scenic stream segments and park ponds that are convenient to many neighborhoods. There is currently a city ordinance that prohibits watercraft on the park ponds. The Plano Trail System Planner decided to see if paddling trails are an option in this area and entered into a partnership with the National Park Service’s Rivers, Trails & Conservation Assistance (RTCA) program. The initial phase of this project required photographic documentation. An ArcGIS Online Story Map was created to allow all the committee members to upload their reconnaissance photographs and record where each picture was taken. Once these point locations were gathered, data entry fields were added to the Story Map point data to facilitate more comprehensive attribute collection.

Title: The Texas Triangle – Demographic Growth, Historical and Future

Abstract: Between 1980 and 2010, Texas’ total population increased by 76.7 percent, from about 14.2 million to more than 25 million, according to U.S. Census Bureau data. Metropolitan areas were responsible for nearly all of the increase, with most growth concentrated in the Texas Triangle, the area bounded by Dallas-Fort Worth, Houston and San Antonio. The Texas Triangle continues to grow and has been ranked amongst top 20 fastest growing metropolitan areas in 2014 by Forbes. Rapid growth will require local, regional, state government agencies to plan infrastructure needs.  Regional public agencies update demographic forecasts on regular basis.  Using GIS as a tool, CDM Smith has provided assistance to these agencies through transportation planning projects and socioeconomic growth analysis.  This poster will demonstrate historical and future population and employment growth in the Texas Triangle.
