Using ASPRS Open Aerial Data Catalog

Registration URL:
Webinar ID: 942-747-811


The ASPRS Aerial Data Catalog is a tool for locating aerial photography over the U.S. and international coverage areas, including details and contact information about individual collections. The Catalog currently uses a keyword searching system.  Users of this Catalog are encouraged to enter information for collections of aerial photography not currently listed, even if the information is incomplete and/or approximate. This service is a contribution of the ASPRS Data Preservation and Archiving Committee (DPAC). The Catalog is provided to the geospatial community, to enable discovery and access of the vast archives of historical and current aerial photography in a way never before possible. By providing a free hosting Catalog with no commercial interests, ASPRS and DPAC aim to make the Catalog the definitive resource for researchers and other users in the geospatial community and beyond. We hope this Catalog will contribute to the protection and preservation of aerial photography around the world.

John Faundeen has worked as the EROS Archivist at the U.S. Geological Survey (USGS) Earth Resources Observations and Science (EROS) Center since 2001. His current role involves policy, oversight and guidance for the observational, cartographic, and elevation data created and maintained at EROS. John allocates most of his time to preservation and appraisal functions. The preservation activity includes environmentally managing a 20,000 square foot archive containing 100,000 rolls of analog film and thousands of magnetic tapes. Establishing an off-site archive containing several petabytes of electronic data continues to be a centerpiece of EROS’s data management risk mitigation strategy. MOUs with the U.S. National Archives and Records Administration were established based upon proven data management capabilities. He has previously served as the acting USGS Records Officer. ORCID  John has served as the ASPRS Data Preservation and Archiving Committee chair for over five years.

Recent developments in 3D city modelling

Webinar ID: 851-697-115

In the last decades 3D city models have been used mainly for visualisation. However, nowadays they are being increasingly employed for simulations and spatial analyses in many application domains. For example, they can be used to estimate the energy demand of buildings, and as a platform to support smart cities. This presentation will present 3D experiences from the Netherlands, and it will shortly overview the current developments in the acquisition, standardisation (e.g. OGC CityGML), and utilisation of 3D city models.

Filip Biljecki is a researcher at the Delft University of Technology in the Netherlands. His main interests are 3D city models and CityGML. Filip is involved in the OGC CityGML SWG and in several other international collaborations.

The Importance of Geospatial Information for Smart Cities

Registration URL:
Webinar ID: 246-192-691


Today, urban population accounts for 54 percent of the total global population (World Health Organization 2014) with a trend to more urbanization.  Effective integration of human, physical, and digital systems operating in the built environment holds the promise of improving the quality of life of urban residents, improving the governance of cities and making cities prosperous, inclusive, sustainable and resilient.  Location is a primary method for organizing Smart City services.  Communicating anything about location requires standards. This talk will address the need for an open information technology framework that is critical to achieving the benefits of spatial communication for Smart Cities.  A recent study of Big Data initiatives in cities identified that found that more than 70% of responding cities are used GIS in their data analytics initiatives.


Bio:  George Percivall is the CTO and Chief Engineer of the Open Geospatial Consortium (OGC). He is responsible for the OGC Innovation Program and the OGC Compliance Program. His roles include articulating OGC standards as a coherent architecture, as well as addressing implications of technology and market trends on the OGC baseline. He serves as the chair of the OGC Architecture Board.

Fri, Jun 9, 2017 12:00 PM – 1:00 PM EDT

Coastal and Marine Surveillance with UAS

Registration URL:
Webinar ID: 328-037-427


Much research has been devoted to development of techniques to improve airborne imaging of underwater features using traditional aircraft equipped with metric-grade cameras. Small unmanned aircraft systems (sUAS) provide a paradigm shift in efficiency and low cost aerial surveying of marine and coastal zones compared to traditional methods. This presentation will show emergent applications of UAS-based remote sensing and photogrammetry to coastal and marine environments. Topics covered will include the following: (1) structure-from-motion (SfM) photogrammetry and optical inversion for mapping littoral zones; (2) airborne fluid lensing for monitoring of aquatic resources; (3) debris mapping and plastics identification. Time permitting, additional examples on the emergent use of UAS for coastal and marine surveillance will be presented.

Fri, Jun 23, 2017 12:00 PM – 1:00 PM EDT

Mapping the Great Lakes Coastal and Nearshore Realm: NOAA’s Lake Level Viewer

Registration URL:
Webinar ID: 424-676-331


Mapping one of the most dynamic environments in the world, the Great Lakes coastal and nearshore realm presents several challenges even with today’s advancements in remote sensing technologies. This presentation will highlight the work that is involved with data collection, processing, and analysis to help in visualizing coastal and nearshore bathymetry and topography of the Great Lakes and its use in understanding impacts from lake level fluctuations. Additional discussion will focus on NOAA’s Lake Level Viewer as a tool for users to visualize impacts, with a brief demonstration, and how to access the data used behind the tool for use in other mapping applications.




Emails for upcoming seminars are sent to all ASPRS, CaGIS and GLIS members with the registration link.  Just click on the clink in the email to get to the online registration for each seminar.  Please note that slots for the live seminar are limited to 95 so register early to be assured you are approved.  It is also important that if you register for a seminar that you do attend as there are more people interested in the live seminars than there are slots available to accommodate everyone.  After the live seminars have aired, a videotape of the seminar will be posted.
