Viewshed Analysis of the Susquehanna River Corridor
Nicole Ernst, Harrisburg Area Community College
Steve Gochenaur, Lancaster County
Christian Przybylek, Lancaster Conservancy
Jacob Trimmer, York County Planning Commission
9:15 – 9:35 a.m. | Room 104
This viewshed analysis project identified lands of high scenic value in the Susquehanna River corridor in Lancaster and York Counties. This analysis looked at what was visible from: 1) scenic vistas, 2) what can be seen if you are paddling in the Susquehanna River, and 3) what can be see if you are hiking along one of the river trails. After the analysis was completed, land use and property data was used to identify parcels of high scenic value.
Streamline Chapter 102&105 Environmental Inspection Using Esri +
Will Hunt and Charlie Tuttle, Potter County
Glenn Dunn, Potter County Conservation District
9:45 – 10:05 a.m. | Room 104
Potter County GIS department & Potter County Conservation district partnered together to streamline DEP chapter 102 & 105 environmental inspections using Survey123, ArcGIS pro, collector, and ArcGIS online. In this partnership we developed a customized Survey123 and its report feature streamline DEP reports and data management of environmental inspections using ESRI products.
Things Are Looking Great From Here +
Steve Kocsis, Cambria County
9:15 – 9:35 a.m. | Room 105
Using UAVs in conjunction GIS to visualize and document current conditions and changes. Cambria County's UAV program works with multiple county departments to fly missions. However it's not just the flying that is the fun part. Applying UAV imagery to 3D modeling and comparison of other imagery is one of the benefits of this technology. However, mission planning and field operations benefit from integrated GIS too. Why stop with aerial products? Cambria County is also working with terrestrial LiDAR to model the inside of buildings and add that much more value to information about geographic locations.
Extending Allegheny County Hydrology Data for the Nine Mile Run Watershed +
Emily Mercurio, CivicMapper
Srini Dharmapuri, Sanborn
9:45 - 10:05 a.m. | Room 105
Publicly available 2015 Allegheny County high resolution QL2 LiDAR data and corresponding orthophotos from the same year provide excellent starting points for creating a hydrologic surface that can be used for basin analyses in the urban environment. These source data were used to create a set of hydroenforced data for Allegheny County resulting in a set of standard deliverables including a 2m hydroenforced DEM and a file geodatabase with 3D breaklines and an integrated terrain database. For the Nine Mile Run Watershed in Pittsburgh, PA, the countywide hydro-enforced data were used as a starting point for creating a watershed scale, higher resolution hydrologic dataset to capture the effects of the urban environment on surface water flow. These enhanced hydrology datasets were then used for sub-basin catchment analyses and peak flow calculations within the watershed. This workflow established a repeatable data development and improvement process that can be followed for similar hydrology extension projects using the forthcoming statewide QL2 LiDAR dataset for Pennsylvania.
Fostering Community Engagement with ArcGIS Hub +
Tim Loftus, Esri
9:15 – 10:05 a.m. | Room 108
ArcGIS Hub provides a platform for two-way community engagement. Attend this session to learn how to use ArcGIS Hub to rally internal staff and external collaborators around initiatives. You will learn how to activate and configure initiative websites, apps and content that engage your community. With ArcGIS Hub, every members of your community can have their own unique identity that enables them to follow initiatives, register for events, share data, take surveys, provide feedback, and join your initiative teams. You learn how ArcGIS Hub helps you interact with citizens and cultivate a virtual workforce focused on improving the community.
New Datums for the Nation: Replacing NAD83 and NAVD88 +
Jeff Jalbrzikowski, National Geodetic Survey
9:15 – 10:05 a.m. | Room 206
As a geospatial professional, you're probably already aware that our beloved national datums, both NAD83 and NAVD88, are scheduled to be replaced in the near future. Join me to learn about what the new datums will be, the science behind how they are being developed, and get some recommendations on how you can start thinking about migrating your data. There will also be a discussion of the deprecation of the US Foot: how it came to be, and why the time is right to retire it.
Multiprocessing Lidar Data with Python in ArcGIS +
James Whitacre, Carnegie Museum of Natural History
9:15 – 9:35 a.m. | Room 207
As Pennsylvania continues to collect lidar data over time, there is a need to compare lidar data collected using different LAS Specification versions. Fortunately, ArcGIS provides lidar tools as part of the 3D Analyst extension to help modify and reclassify LAS point data. Using ArcPy, many workflows can be automated, however, some tools can take many hours for larger datasets even on higher-end workstations. Using the Python Multiprocessing module, many of these tasks can be processed in parallel to decrease processing time. This session will provide examples and demonstrations for how to simply use multiprocessing Python tools to modify PAMAP lidar data collected from 2006-2008. The methods outlined can also be applied to other ArcGIS geoprocessing tools that can benefit from multiprocessing workflows.
Designing Maps for People of All Abilities
Patrick McKinney, Cumberland County
9:45 – 10:05 a.m. | Room 207
In this session, we will be discussing how to ensure our printed maps, electronic maps, and interactive web map applications can be used by people of all abilities. We will review web accessibility principles, and preview tools that can help us in making accessible web apps. Topics include screen readers, color contrast, automated tests, and the limitations of commercial-off-the-shelf solutions.
In addition to web accessibility, we will be considering general principles when designing maps in any format. These include reviewing the map in different environments, how we approach labels and symbology, and how to measure how our maps are being used.
Survey123: It's Not Just a Field App Anymore! +
Joseph Livoti, Hampton Township
9:15 – 9:35 a.m. | Room 218
Survey123 has a great ability to allow non GIS people to create and populate attributes in a geopoint with its simplicity. Normally this is done in the field using a mobile device and that device's built in wi-fi/cellular signal to help create a feature point. This presentation takes the simplicity of Survey123 and demonstrates how to make it a viable office application without the need for a wifi or cellular connection in order to create a point on the map.
The Pennsylvania Geological Survey's Use of Drones
Craig Ebersole, DCNR - Bureau of Geological Survey
9:45 – 10:05 a.m. | Room 218
The PA Department of Conservation and Natural Resource’s Bureau of Geological Survey is exploring the use of drones to enhance existing geological mapping and geohazard projects, and to enable new areas of study. This talk is focused on helping those interested in implementing a drone program at their organization and will include equipment and software considerations, geological applications of the technology, and lessons learned. |
