The Impact of Climate Change on Coastal Communities | GEOTalks Ep. 7

• About this episode • Storm surges and sea level rise pose greater risks to coasts each year. Maine felt the effects of climate change this past winter when powerful storms and flooding berated its coast. The Camp Ellis Jetty was particularly vulnerable to these storm surges and sea level rise, and the Saco Bay community lost nearly 40 homes as a result. In this episode, we spoke with Dr. Will Kochtitzky who is leveraging GIS technology, lidar, and photogrammetry to study the effects of sea-lev...

Understanding Secondary Tropical Dry Forests with Lidar Technology | GEOTalks Ep. 6

Lidar technology, in addition to other methods of remote sensing, can be integral to performing accessible research in a given area. This month on the GEOTalks Podcast, we spoke to Dr. Arturo Sanchez-Azofeifa about his team’s research in the Guanacaste Conservation Area at Santa Rosa National Park, Costa Rica. His team is creating accurate methods for studying secondary tropical dry forests with lidar technology. Listen to the episode to hear Dr. Sanchez-Azofeifa explore the history that establi...

Global Mapper’s Origin | GEOTalks Ep. 5

You may know the Global Mapper software suite, but do you know how it was created? Mike Childs created Global Mapper — known then as dlgv32 — as an intern at the USGS in 1997. This version had a fraction of the power of the Global Mapper we know today, however, it boasted great GIS mapping functionality for the time. Mike Childs joined the GEOTalks team to unpack Global Mapper’s origin story and discuss what’s made it such a fulfilling project to develop. Blue Marble Geographics CEO and Presiden...

Accessible Bathymetric Data & Its Impact on Marine Conservation in the Beqa Lagoon | GEOTalks Ep. 4

Bathymetric surveys provide vital information that informs decisions about marine environments and communities. Tomer Ketter of Map the Gaps and SubMerge, and Sefano M Katz of the Pacific Blue Foundation’s Beqa Lagoon Initiative, joined us on this episode of GEOTalks to share insights from a collaborative bathymetric survey they performed in the Beqa Lagoon in Fiji. The livelihood of Fiji’s people is tied to its land, waters, and the diverse ecosystem that thrives there. In the episode, they exp...

How Texas is Using GIS for Conservation with Kelsi Schwind | GEOTalks Ep. 3

Kelsi Schwind joined us on the GEOTalks Podcast to explore how GIS technology can enable progress in conservation. We discussed the budding efforts to preserve the Texas Hill Country’s Bigtooth maple population, which is imperiled in this region. In our discussion, Kelsi highlighted how her automated method for extracting canyons has enabled her team to perform thorough research on Bigtooth maple communities and establish an automation to research this species for years.

Tracking Forever Chemicals (PFAS) with GIS Technology featuring Katrina Schweikert | GEOTalks Ep. 2

About this Episode Per- and polyfluoroalkyl substances (PFAS) are a family of chemicals defined by carbon-fluorine bonds that make them resistant to fire, water, and oil. When PFAS were discovered in our farmlands and waterways, studies indicated that these chemicals have adverse, long-term effects on our environment and bioaccumulative effects in humans and other organisms. A team from the University of Maine at Orono, led by Dr. Torsten Hahmann, is developing a solution to track nationwide PFA...

Studying Coastal Salt Marshes using Drones with Andrea Celeste Curcio | GEOTalks Ep. 1

About this Episode The effects of climate change are present around the world, especially in coastal salt marshes. In this episode, we speak with Andrea Celeste Curcio, who has been evaluating the performance of remote sensing with drone/UAV technology (photogrammetry/lidar) and hyperspectral sensors for researching salt marshes over time. She explores the utility of using drones for monitoring coastal ecosystems and shares her insights on the process. YouTube: https://ow.ly/7Zft50SCpy2 Spotify:...
