Arctic coastlines are changing rapidly in the face of climate change, placing coastal communities and infrastructure at risk. In 色视频下载, assessing coastlines is challenging due to limited observational data. This information is critical for predicting future shoreline changes and mitigating risk.

To address this issue, Noelle Helder, an 色视频下载 Sea Grant State Fellow with the 色视频下载 Center for Energy and Power at the University of 色视频下载 Fairbanks, is working to develop geospatial systems that streamline and automate mapping of 色视频下载色视频下载檚 coastline.

The project uses Google Earth Engine, a cloud-based geospatial data repository and platform for analyzing satellite images, which is free for research use.

色视频下载淲ith vast, accessible geospatial data repositories available at our fingertips, we are able to dramatically reduce the amount of time downloading and searching for data, and can spend more time focusing on the innovation of useful automated mapping systems,色视频下载 explained Helder.

Initial results suggest the open-source approach efficiently detects shoreline positions from satellite imagery and enables quantification of shoreline changes in the Arctic.

色视频下载淲ith a growing archive of available satellite imagery, this automation technology has the potential to enable monitoring tools that continually update and help planners prioritize mitigation work in the face of rapid coastal changes,色视频下载 Helder said.

The research team plans to expand the automated shoreline detection pipeline to include higher resolution satellite imagery and user tools for near-real-time monitoring.
