New Land Cover (Part 2): Land Cover Change and Trends in the Long Island Sound Watershed

This is the second webinar in UConn CLEAR’s two part series introducing their updated land cover tracking tools. Using data from the Annual National Land Cover Database (NLCD), this session explores how land cover across the entire Long Island Sound watershed has changed from 1985 through 2023, covering regions from Connecticut to the Canadian border.

This webinar highlights trends at the watershed, state, town, and local levels, with special attention to the 300 foot riparian zone along waterways, a critical area for stream health and climate resilience. The session will demonstrate how to interpret land cover change data using CLEAR’s map viewer and dashboards to better understand long term environmental patterns.

USGS Compound Flood Hazard Web Map

The USGS Long Island Sound Partnership Compound Flood Hazard Web Map Application is an interactive tool developed by the U.S. Geological Survey’s New York Water Science Center that helps users explore the combined impacts of multiple flooding drivers across the New York and Connecticut coastal regions. Drivers of compound flooding included in the assessment were precipitation, coastal (storm surge, tidal), and groundwater emergence, which when combined can lead to more severe and widespread inundation than from any single cause alone.

The map visually displays hazard rankings and spatial patterns of flood drivers so that planners, emergency managers, researchers, and the public can better understand where these flood hazards are most likely to coincide, thus supporting local decision making for flood mitigation, coastal planning, and resilience strategies. The application is based on USGS models and ongoing research into regional flood processes.

UConn CLEAR Webinar: Connecticut’s Lidar and Orthoimagery

UConn CLEAR is offering a series of engaging webinars this winter, including an in-depth session on Connecticut’s ongoing Lidar and orthoimagery project. This presentation will explore the statewide effort that began in 2022 and continues through 2026. Speakers from Dewberry will explain the data products created from the 2023 acquisition and highlight how these datasets are being used in planning, mapping, environmental analysis, and other geospatial applications. The session is designed to help participants understand the importance of high quality elevation and imagery data in supporting statewide decision making.

The webinar will also discuss potential uses for these datasets in the coming years and provide a preview of the planned 2026 acquisition and delivery. Participants will gain insight into how Lidar and orthoimagery support climate resilience work, infrastructure planning, land use analysis, and broader environmental assessments. This session is open to anyone interested in geospatial data, statewide imagery, or Connecticut’s evolving GIS resources, and registration is available through UConn CLEAR.

UConn CLEAR Webinar

This UConn CLEAR webinar provides an updated overview of Connecticut’s ongoing statewide Lidar and orthoimagery project. Dewberry’s technical team will introduce the data products generated from the 2023 acquisition and explain how these datasets are being used across environmental planning, land management, infrastructure mapping, and community decision-making. The session is designed to help participants understand the value of high resolution elevation and imagery data and how these resources support public agencies, researchers, and local communities.

The webinar will also look ahead to the 2026 phase of the project, offering insight into expected updates, new deliverables, and potential applications for longterm statewide planning. Attendees will gain a stronger understanding of how Lidar and orthoimagery fit into Connecticut’s geospatial data strategy and how these datasets can support climate resilience, hazard mapping, and improved environmental analysis. This session is open to anyone interested in GIS, remote sensing, or the state’s evolving geospatial data resources.
