GIS for the Non-GIS Professional: Empowering Public Outreach

Michael Couch

As GIS technology becomes more sophisticated and data sources continue to increase in number and depth, the challenge for the modern GIS professional is less about whether something can be mapped than how it can best be mapped so that others can use the information. For the GIS professional, the public is often as much a stakeholder as any member of their organization. But how can a GIS output reach them in a world with a 2-second load-time attention span? Case studies in public outreach mapping for hazard mitigation planning in Tulsa and capital improvement planning in Broken Arrow will be discussed.

Current High Resolution Aerial Imagery and 3D in Local Government

John Ford

The aerial imagery market is evolving and there has never been a bigger demand for current, high resolution imagery to support local government internal applications as well as machine learning to detect change in structures or impervious surfaces. Nearmap delivers current, high resolution orthos, obliques, 3D Mesh and Digital Surface models across 430 urban areas in the US as a cloud service or on premises. John will be showing recent captures in OK and talking about how our products are being used across the state to drive innovation and reduce costs. He will also be talking about Nearmap works with government entities to select the right mix of products and work jointly on building a business case to drive the most value for your organization. We take the risk out of acquiring imagery by spreading the cost across all our subscribers and delivering imagery as soon as you start a subscription.

Positional Precision Analysis of Orthomosaics Derived from Drone Captured Aerial Imagery

I-Kuai Hung, Daniel Unger, David Kulhavy, and Yanli Zhang

We flew a DJI Phantom drone once a month over a seven-month period over Oak Grove Cemetery in Nacogdoches, Texas, resulting in seven orthomosaics of the same spatial location. We identified 30 ground reference points (GFP) based on permanent features in the cemetery and recorded the geographic coordinates of each GFP on each of the seven orthomosaics. Analyzing the cluster of each GFP containing seven coincident positions depicts the precision of location of the orthomosaics produced from drone captured aerial imagery. Our analysis of positional precision is an attempt to answer the fundamental question, “Are we obtaining the same geographic coordinates for the same feature found on every aerial image captured by a drone over time?” The results showed that the positional precision of an orthomaic produced from drone acquired imagery was higher at the center of the mosaic compared to the edge areas. In addition, the positional precision was lower along the direction of the drone flight.

Implementing Triggers to Streamline data collection and mapping

John May

Cloud based platforms coupled with ArcGIS Collector offer easy to use tools enabling interaction with spatial and non-spatial data. Complex data can present challenges when attributes need to be retrieved from other feature classes or related tables. These challenges can be addressed with triggers that leverage native STGeometry functions. Imagine a feature class whose attributes included items such as county name, FIPS code, drainage basin, etc. Traditionally these would be derived from a combination of geoprocessing functions and manual data entry. A simpler approach would be to implement a trigger using the STGeometry functions available in your Enterprise database and automate geoprocessing and attribute collection without impacting the user experience. A similar approach can be used to symbolize data on your web maps with information stored in related tables. Automating data with triggers will result in improved work flows, enhanced application usability, and reduced data errors.

The PCI+ Python Model: Selecting Road Projects that Optimize Pavement Condition Plus Other Civic Priorities

Dr. Kevin Gustavson & Craig Schaefer

The City of Tulsa has developed a Python model using ArcPy to optimize the selection of road rehabilitation projects. A consultant provides a patchwork of suggested road improvements that would maintain a desired citywide Pavement Condition Index (PCI) value. The model transforms these disparate selections into workable PCI equivalent arterial corridors and major intersection projects. The model also compiles data about other city priorities (i.e., replacing problem pipes, improving disability access) and assigns points for added benefits, normalized to road length. Scores are curved to equalize points in each civic category so that administrators can adjust the weights for a final score. Roads are considered in descending score order and are selected if they meet the PCI criteria without exceeding the budget for the council district/s in which they reside. The result is a largely automated process that selects street segments to maximize city objectives while meeting the target PCI.

Condition Assessment of Storm Sewer Systems: An Overview

Jason Kleps

Communities need to know the location and condition of their storm sewer assets to maintain an optimal system. This is especially important for communities with decades-old infrastructure. City engineers and planners need a tool to guide them in their capital improvement planning and help rationalize the allocation of limited resources. For over three years, Meshek & Associates has been engaged in a project to inventory and assess the City of Tulsa’s storm water system. This presentation will discuss how condition assessment can give a community the information it needs to intelligently manage its assets along with a real-world example of such a project.

Utilizing GIS for Parks and Recreation

Matthew Her & James Kelt

The City of Broken Arrow Parks & Recreation Department is transitioning toward fully implementing an asset management system through GIS. Geographic Technologies Group (GTG), Green City GIS laid the foundation of the Broken Arrow Parks and Recreation GIS system on an ArcGIS platform. Using the Broken Arrow Parks and Recreation data, park maintenance staff were trained by GTG on how to inventory future and evolving assets into the ArcGIS Collector application. In addition, GTG generated an interactive parks locator and story map to help the public learn more about the Parks in the Broken Arrow community. We will dive into the process of how the Parks and Recreation Department initiated this application and what to look forward to in the future.

Managing Change and Setting Governance Goals in a Growing County

Aliza Etkind

DCGIS is in the process of developing and implementing a governance model to facilitate service needs. The dependence on GIS services has increased within the last decade. GIS solutions and applications are now more specialized, providing opportunities for more specific audiences. Presently, end users use GIS datasets for day-to-day tasks and operational pictures are driven by GIS data. Increased dependence has required an increase in accuracy and timeliness of revisions. This has also required increased knowledge in end user laws, rules and regulations to ensure GIS data is compliant and useful. Currently, DCGIS has no specific governance model or policies in place for data requests or updates. Communication gaps exist in many GIS workflows. Communicating needs with end users and stakeholders will allow DCGIS to develop and implement proper policies, increase governance across the county, and standardize GIS data and workflows.

Make Spatial Data Work for You: Increasing Public Engagement Through Open Data and Dashboards

Chanyalew Girmay

Access to reliable and up-to-date information is critical to decision making. The City of McKinney GIS Department is sharing real-time geospatial information with members of the organization and the public by leveraging Esri’s Open Data and Dashboard solutions. The city’s Open Data site, “Explore McKinney”, was launched in November 2017 and provides convenient access to the city’s spatial data with the goals of increasing citizen engagement and government transparency. “Explore McKinney” is the hub for the city’s web apps, spatial datasets, and printable PDF maps. Additionally, the GIS Department is deploying a fire hydrant inspection and maintenance dashboard, replacing the old paper-based approach. This GIS based solution uses Collector for ArcGIS and the Operations Dashboard for ArcGIS to streamline the inspection process and monitor and display the current status of inspections.

New approaches to old maps: Initiatives underway at Oklahoma State University Library’s Maps and Spatial Data

Kevin R Dyke

Paper maps contain a vast amount of spatial data. Most of this data is unavailable in any other form. In this session I will demonstrate a number of projects underway in Maps and Spatial Data at Oklahoma State University's Edmon Low Library. All of these efforts seek to spotlight and preserve Oklahoma’s cartographic heritage. These projects include a spatial search interface for finding maps, a web-based tool for aerial photograph comparison, the 3-D reconstruction of a no longer extant campus building, and, thanks to the generous support of the McCasland Foundation, the addition of hundreds of new maps to the Oklahoma Digital Maps Collection, bringing the total number of maps available online to the brink of 10,000. Through all of the projects, I hope to make all of these old maps feel new again.

Critical Response to Schools: Fostering GIS in Public Safety

Betsi Chatham

In the summer of 2018, the City of Grapevine Police Department began preparedness discussions in response to the unfortunate incidents occurring in some of our nation’s schools. An integral part of those discussions was how to enter a school, contain assailants, and protect the lives of students and teachers. The idea of gathering as much spatial information about school campuses sparked a relationship between the Special Weapons and Tactics (SWAT) and GIS. A simple yet strategic database was developed to enable exterior and interior data to be collected through Esri’s Collector for ArcGIS. A Common Operating Picture was easily obtained through a standardized data viewer and hard copy maps for SWAT personnel, Incident Command, and Dispatch.

Water Rescue and GIS

Lt. Ronald Vaughn

Public Safety agencies that respond to Emergencies on bodies of water need to know the best locations to launch their boats and know where hidden dangers are underwater. There are several jurisdictions around the country that respond to drownings and body recoveries. These incidents are intense and stressful. They are high profile incidents with news media coverage. Depending on local protocols these events can involve several agencies. In this presentation I will discuss how Dallas Fire Rescue is leveraging the power of GIS to assist our Boat Rescue Team with Water Rescue and Recovery.

Precision analysis of orthomasaic map photogrammetrically derived from UAS images

Yanli Zhang, Daniel Unger, I-Kuai Hung, David Kulhavy

High spatial resolution orthmasaic map can be derived from UAS images. Surveyed ground control points (GCP) can improve the photogrametry analysis procedure. However, due to the high cost of land surveying, the establishment of GCP are not very common in practice. This research had 30 flight missions of the study site and try to estimate the precision of the orthomasaic maps. Possible impact factors are identified. Based photogrametry analysis, a 3D model was also derived and printed for the study site.

Build an easy to use QA/QC tool with ArcGIS Collector

John May

Distributed GIS environments can have many different groups collecting GIS data for the system. Whether it is a team of dedicated in-house staff, external contractors, or a combination of both, the information collected most often is pushed into the same database. If it is important to your organization to review data before making it public you can do an end run on versioning and replication by implementing a few easy tricks in your database and using ArcGIS Collector as a data QA/QC tool. The QA/QC tool will allow you to review data and determine if it should become visible in the production data environment or be edited before becoming available. This approach delivers an easy to use tool that streamlines data management and automates the data review process.

Pipeline and Changing Data Needs

Sheila McGinty

The pipeline industry faces changing GIS data needs as the regulatory environment changes. This presentation will discuss past and future changes that affect how GIS data is stored, specifically related to Class determination on gas pipelines. The changes in GIS data can be a direct result of new regulations or the result of software changes required to meet regulations. GIS data changes include the topology, attributes, and accuracy of the event. Some examples of data changes to be explored include line connectivity, linear referencing, the potential impact radius (PIR) calculation, data accuracy within the attribute table, and location accuracy. A conservative approach to safely meeting the regulatory requirements will be discussed.

Mapping the External Lighting and Illumination of Campuses

James Walker & Robert Oleson

Garland ISD uses GIS for several purposes including Transportation, Demographics and Campus and Facility mapping. Last year the GISD Security department asked if GIS could be used to help with studying night time campus illumination and inventorying outdoor light fixtures in order to better facilitate periodic lighting inspections. This resulted in two related but parallel GIS projects. First we added the lighting fixture data to our existing facilities database so that maps could be produced and so that each fixture could be better identified when Security needed to put in work orders. Second we developed a workflow to collect and process night time illumination readings taken with a gps enabled cell phone. This data was then be processed to create a raster layer showing night time campus illumination levels. Our presentation will outline the existing GISD facilities GIS data environment, and then go through the details of our Lighting and Illumination projects.
