This guided presentation showcases the history and methods of Atlanta tree canopy classification. Step through the project timeline and read about the results of comparing imagery from 2008 and 2014. See statistics and metrics for the Urban Tree Canopy in the City of Atlanta, with discussions regarding the implications of land cover and canopy change.
Highlights include an overview of the land cover classification process using satellite imagery, from raw imagery to classification and finally aggregation to cell study areas and other geographic boundaries.
After learning about the history and process of the Atlanta Urban Tree Canopy project, dive further into the data with this useful mapping application. Datasets developed from 2008 and 2014 classified canopy studies are linked to common geographic boundaries like neighborhoods and council districts. Filter through data layers, create charts and graphs of canopy cover values, or take a closer look at the raw imagery.
Start exploring Atlanta canopy data here – change visible layers, filter results, view different basemaps, and add you own data to the map. Results can be saved to PDF for easy sharing.
Read about some key points of the Atlanta UTC project before exploring satellite imagery to detect changes to the landscape. Imagery from 2008 serves as the basemap, with a spyglass viewer revealing the 2014 land cover. Finished with a brief summary of the 2008-2014 change analysis, this mapping application highlights how quickly both grown of canopy and development of land occurs in the city.
Part of the data-validation process used for the 2014 tree canopy update involves boots-on-the-ground verification of changes identified in the satellite imagery. The research team visited 150 locations throughout the city to confirm trends and changes identified during the analysis – this application showcases some of the areas displaying the most drastic change since 2008.
Results from the 2008 Urban Tree Canopy Analysis placed Atlanta at the top of the list for canopy cover for similarly sized urbanized cities – the lush ecosystem and mixture of hard and softwoods native in the southeast contribute to Atlanta’s extraordinary canopy cover. Atlanta’s city limits are superimposed over other select cities to show landscape and canopy variation in this map application.
This report provides a comprehensive analysis of the original Urban Tree Canopy study - from introducing the benefits of urban trees to pinpointing target areas for planting more trees.
This map shows all the layers associated with evaluating Atlanta's tree canopy, including Urban Tree Cover, Watersheds, Atlanta Neighborhoods, City Council Districts, and much more!
