Title:  Progress in Motion: Keeping Up with the City of Frisco ’s Water and Wastewater Development

Author:  Sherrie Hubble, Freese and Nichols, Inc.

The City of Frisco, Texashas experienced a tremendous amount of growth over the last twenty years,having been designated the fastest-growing city in the nation in 2009 and the fastest-growing on average from 2000 through 2009. Residential and commercial development has taken place at an astounding rate, with a total of 3,000 residential development permits issued and 30 permits issued for new commercial projects in the year 2012 alone. An important part of the development review process includes determining the effect of this new growth on existing infrastructure and what kind of additional water demand and wastewater flows will be triggered as a result of incoming development. The poster presentation highlights some of the most recent residential and commercial projects in the City of Frisco, and, specifically, illustrates the process of how Freese and Nichols, Inc., an engineering firm, evaluates the water and wastewater systems to make capital improvement recommendations for new development.


Title:  Optimized Tapestry HotSpot Grouping Analysis

Author:  Garri Grossi, Interstate Batteries

This map is a focused study of where the typical Recreational Vehicle owner lives in relation to existing repair and service locations. Analysis components include defined ESRI Tapestry Segmentation Profiles, the Spatial Autocorrelation tool to confirm the significance level (p-value) and z-score, and the Optimized Hot Spot Analysis tool so determine significant demographic clustering. The result defines locations where a seller of RV-related services and accessories could effectively focus their marketing.

Title:  Overhead to Underground:  A 3-D GIS Utility Relocation Representation

Author:  Larry Jahn, Cobb, Fendley & Associates

Overhead utilities are relocated underground for beautification purposes, economic development, and damage prevention.  Relocating utilities underground creates an attractive streetscape, increases green space, and appeals to new development.  Other important benefits of the relocation include securing and protecting the utilities from everyday environmental factors, ensuring service continuity. ArcMap and ArcScene were used to model the visualization and illustrate the transition of utilities from overhead to underground.


Title:  GSI Tornado Website for Disaster Recovery at Riverwind

Author:  The Chickasaw Nation Department of GeoSpatial Information

Last May, many Oklahomans were devastated by tornadoes; several of which were Chickasaw citizens and employees. A Chickasaw Disaster Relief and Recovery command post was setup Riverwind Hotel in Norman, OK .  Chickasaw Nation’s Department of Geospatial Information created an ESRI ArcGIS web application used at the Chickasaw Command Center . The Chickasaw Nation Emergency Management System (EMS) web application is based on the ArcGIS API for Flex and allowed thousands of addresses to be geocoded.  With the tornado path already projected, EMSefficiently located those Chickasaw citizens and employees affected by the tornadoes.  The post-imagery allowed a citizen or employee to view their location and help workers understand the extent of their damage. The EMSapplication allowed Chickasaw Nation volunteers to start the clean-up process for those homes affected. The EMSplayed a key role in the retrieval of information pertaining to the Chickasaw citizen or employee.  


Title:  GSI Goes Mobile, Building the LHP Mobile App

Author:  The Chickasaw Nation  Division of Construction & SupportServices Department of GeoSpatial Information

Tribal jurisdiction is a major issue for tribal police departments. The Department of GeoSpatial Information (GSI) has simplified jurisdictional and boundary issues by creating a custom Lighthorse Police web application. The web application not only provides officers with tribal boundaries and jurisdictions, they are also able to view tribally owned/allotted lands, facilities with pictures and floor plans, area emergency management services, and high resolution imagery. This poster provides a step-by-step look at the process GSI used to create a mobile application for the Chickasaw Nation Lighthorse Police. It demonstrates how GSI leverages Arcgis for iOS to give_GoBack officers the same capabilities of the custom web application in a real-time app for the iPhone/iPad. The mobile application provides officers with jurisdictional information when it is most needed, in the field. In addition, the mobile app gives officers the ability to collect incident information at the scene and have it saved to a private 'i-house' server to be used for future crime analysis.

Title:  HPA Creation

Author:  Brent C. Cochran, SWCA Inc.

SWCA Inc., an environmental and cultural resources surveying company, surveys proposed pipelines for Oil and Gas companies to determine if there are any culturally significant sites to avoid.  Because of issues involving cost and time, the area surveyed is reduced to those deemed potentially significant by professional archaeologists, a task facilitated by GIS analysis.  Areas known as High Probability Areas (HPAs) are created along the survey corridor where it intersects streams and waterbodies, often the location of significant cultural locations.  This poster intends to show the step-by-step process of how the HPAs are spatially created.

Title:  Utilizing GIS to collect and manage billboards in Oklahoma

Author: David J. Littlejohn, Natasha Moody, Bryan Salsieder, CEC // Infrastructure Solutions

This poster highlights the GIS tools and processes implemented by CEC to more efficiently and accurately collect and manage the state-wide dataset representing billboards.  This effort introduces GPS domain standardization, automated map production, geodatabase management, and web application development into sign inventory in Oklahoma .

Title:  Justices of The Peace – Caseload Inputs & Precinct Planning

Author: Bret Fenster, Collin County

(Where does all the work come from?)

This is a portrayal of different kernel densities which show potential inputs to the JP caseloads in

Collin County . Our County Administrator requested this map to help plan JP redistricting with a goal of even workloads for each precinct. The major inputs depicted are retail, multi-family housing, traffic counts and population. It’s a challenge to redefine existing boundaries without adding new offices!


Title:  Potential Locations of Astragalus mohavensis in Clark and Nye Counties, Nevada

Author:  Matt Kitchen, Adams Environmental, Inc.

Astragalus mohavensis is a rare plant located in Clark and Nye Counties, Nevada.  Surveys are currently being conducted to locate its presence.  Using existing data and information regarding previous discoveries of Astragalus mohavensis, a model has been developed to attempt to predict its most likely locations.  This map depicts both the potential locations of this species in Clark and Nye Counties as well as the model used to predict these locations.
