2014 Study - Results and Resources

Continued efforts from the project team focused on analyzing canopy change reveal trends and patterns in the loss and gain of Atlanta’s Urban Tree Canopy (UTC). Results are summarized through our online apps and story maps. Click an image below to go directly to one of the 2014 Atlanta UTC Study applications.

UTC Story Map

Atlanta UTC Story Map

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.

Canopy Change Viewer

Canopy Change Viewer

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.

City Canopy Comparison

City Canopy Comparison

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.

2008 Study - Results and Resources

Researches at Georgia Tech have studied greenspace in the City of Atlanta since 1999. The first city-wide tree canopy study used imagery from 2008 to draw conclusions about the state of the Urban Tree Canopy (UTC) in Atlanta. Click an image below to learn more about the first UTC study.

About

The Georgia Tech Center for Spatial Planning Analytics and Visualization (formerly the Center for Geographic Information Systems) has a storied history of developing tools for remote sensing and geospatial analysis. For nearly 30 years, the Center has collaborated with educational institutions, state and local governments, and nonprofits to deliver top quality GIS products and services. After partnering with the Atlanta's City Planning Department to develop a baseline land cover and tree canopy estimate in 2008, and update to the project using imagery from 2014 was completed in 2018. Tracking change across the years allows for identification of land use and development trends, as well as quantification of the state of Atlanta's Urban Tree Canopy.
