Orthoimagery (3 inch pixel resolution) and Lidar elevation data for all of Connecticut collected in the spring of 2023. This is the first Quality Level 1 statewide Lidar acquisition for Connecticut.
The imagery was collected for the photo interpretation and delineation of submerged aquatic vegetation (mainly Zostera marina, or eelgrass) in Long Island Sound. These data are a continuation of other USFWS efforts to map eelgrass in previous years.
Orthoimagery (3 inch pixel resolution) and Lidar elevation data for all of Connecticut collected in the spring of 2016. The flight is Connecticut's first statewide acquisition this high level of detail
Information about and different ways to view the 1934 aerial photo mosaic created by UConn MAGIC. CLEAR is also working on an image service of 1934 tiles with high quality georeferencing.
The purpose of the Long Island Sound Blue Plan is to identify and protect places of traditional use and ecological significance, and to minimize conflicts, now and in the future. This includes preserving a collective vision of Long Island Sound, and facilitating a transparent, science-based decision-making process. The Blue Plan Map Viewer contains all data layers for the project in a format for exploration.
water quality and impervious surface
Layers supporting Connecticut's MS4 Stormwater permit including 2012, 1 foot, statewide impervious surface are available for viewing and download.
To better understand how Connecticut’s coastal area marshes and roads may respond to sea level rise (SLR), Sea Level Affecting Marshes Model (SLAMM) was applied to Connecticut’s shoreline. This viewer displays the model’s results for Connecticut’s 21 largest marshes and all coastal area roads.
Land Cover on CT ECO includes the Changing Landscape project and a High Resolution Land Cover dataset. The Changing Landscape project is 7 dates of consistent land cover spanning 30 years (1985-2015) and change. It covers both Connecticut and the larger lower Long Island Sound Watershed.
