PA GIS Conference
Wednesday Breakout Session Descriptions
Wednesday, May 12, 2021 - Session Descriptions
10:45 - 11:35 a.m.
Session descriptions will be available in March 2021.
= technical session
Using UAV for Utility Inventory and Disaster Response
Todd King, McKim & Creed, Inc.
10:45 – 11:05 a.m. | Room 104
Unmanned aerial systems (UAS), more commonly known as drones, can be time-efficient and cost-effective tools for utility inventory and disaster response. Drones are effective tools to collect base mapping data for water, wastewater and stormwater planning; engineering design; asset management; etc. They are also useful tools that help support continued operations and maintenance needs, including annual storm basin inspections, erosion documentation/analysis, etc. A UAS can collect data in a fraction of the time historically required for conventional survey and can produce a product that is six to 12 times the resolution of traditional aerial imagery.
These kinds of efficiencies help authorities, utilities and municipalities maximize their capital improvement funds and provide a safe and effective method for surveying linear and/or congested sites.
In disaster response situations, UAS is the perfect tool to record site conditions pre- and post-emergency. It can be deployed quickly; can easily maneuver around and through affected areas; and provides high-quality imagery that enables the municipality to fully
document the extent of damage.
Using Elevation Data to Produce an Updated Statewide Hydrography Dataset
Ellen Fehrs, DCNR Bureau of Geological Survey
11:15 – 11:35 a.m. | Room 104
The PA Department of Conservation and Natural Resource’s Bureau of Geological Survey is using Lidar derivatives to produce a scale-equivalent and dynamic hydrography dataset for the state of Pennsylvania, the methodology of which focuses on a new wave of collaborative efforts. This presentation describes the scope of the hydrography project, the processes used thus far, examples of the
products, concerns and pitfalls encountered in the workflow, and goals for future work.
Teaching GIS for Assessors and how to earn GISP credits!
Amy Francis, Butler County
Sarah King, Erie County
10:45 – 11:35 a.m. | Room 105
Whether you are interested in earning credits for continuing education for a CPE license or trying to earn credits towards your GISP certification, this presentation will showcase 3 examples of classes that have been taught recently to the Assessor's Association of PA (AAP). We will be going through the approved outline of what would need to be taught in a GIS for Assessment class and how to
answer specific questions for Assessors when teaching.
Leveraging Change Detection: Keeping datasets current using imagery & LiDAR
Drew Meren, Quantum Spatial
10:45 – 11:05 a.m. | Room 105
As datasets age, it is important to maintain their currency. Whether it is impervious growth, land use change or erosion of waterways, monitoring changes is critical to providing appropriate services to your communities. Multi-date imagery and LiDAR in combination with advances in machine learning and more robust software, are being used to both identify where change is occurring and identify what sort of change is happening. The workflow that takes the identification of change through to map updates is complex and depends on the type of update wanted. Quantum Spatial in this talk will provide considerations and options available as you undertake these updates with your datasets.
Geo Enabled Elections
Justin Smith, Cumberland County
– 11:35 a.m. | Room 108
Integrating GIS in elections increases voter accuracy and efficiency. Cumberland County GIS assists elections by ensuring that electors vote at the proper place. Court ordered precinct boundary descriptions are drawn as polygon layers. Registered voters in the Department of State database are synchronized with GIS. Municipalities are providing GIS analysis maps for drafting new precincts. Potential polling place options can be quickly queried. A voter Locator application assists the county elections department with their day to day mapping needs.
Using Real Time Information Across the Platform
Alex Brown, Esri
10:45 – 11:35 a.m. | Room 206
As GIS professionals, you’ve probably noticed the increase in real-time data – this will only increase as the world becomes more instrumented and the Internet of Things (IoT) becomes more prevalent. However, working with these real time data sources does not have to be complex, or even require enterprise GIS technology. This session will give an overview of core capabilities within ArcGIS for working with frequently-updated data, techniques for working with live services and more. Learn how you can begin to take advantage of real-time GIS for improved decision making and analysis.
Regular Expressions & Python for Joining GIS-related Data
Christopher Jon Jursa, Washington County
10:45 – 11:35 a.m. | Room 207
While GIS data is commonly available in geodatabase feature classes and shapefiles, GIS-related data can exist in documents such as PDFs, web pages and Excel spreadsheets. If not formatted for immediate use, the data may be recovered in a systematic fashion using search patterns. This presentation will describe how to access a document, extract text and search for consistent patterns of data with regular expressions in Python. Search patterns to extract letters, numbers and other characters will be described so that attributes such as parcel identifiers can be discovered. The goal is for the audience to see the flexibility of regular expressions to discover data to join to your GIS data as opposed to manual string extractions and other Python string operations that may require multiple lines of code.
Philadelphia’s Enterprise GIS: What’s that ‘GeoJawn’?
Brian Ivey, City of Philadelphia
10:45 – 11:05 a.m. | Room 218
The City of Philadelphia's Enterprise GIS is the backbone that powers geospatial analysis, mapping and visualization, data management and sharing, and decision making while fostering creativity, collaboration, and innovation. This presentation will focus on the data, people, systems, standards, processes, and procedures that fuel Philadelphia’s award winning Enterprise GIS while raising the bar for what Philadelphians should expect when interacting with city government.
Integrating UAV and LiDAR Data with a Riverbank Erosion Study
Scott Zubek and Blair Phelps, Tioga County
11:15 – 11:35 a.m. | Room 218
This presentation highlights a collaborative effort to integrate recently captured UAV imagery, historic imagery, and elevation model data via ArcGIS Pro’s 3D mapping capabilities in order to better visualize riverbank erosion hotspots along the Tioga River and its tributaries.
