Maps of vegetation dynamics in Berlin between 1988 and 2017

Results of the analysis described in the article: Cortinovis C., Haase D., Geneletti D. (2023).  Gradual or abrupt? An algorithm to monitor urban vegetation dynamics in support of greening policies. Urban Forestry & Urban Greening.  https://doi.org/10.1016/j.ufug.2023.128030

The article applied an algorithm to characterize vegetation dynamics in the city of Berlin in three decades between 1988 and 2017. The algorithm distinguishes the contribution of gradual and abrupt changes to the total change observed during the analysed period. The results are presented as raster maps in .tif format with a resolution of 30 m, EPSG:3035. Areas outside the city administrative boundaries and water areas are masked (nodata).

netChange_1988-2017_masked.tif is the map of the total net NDVI change (calculated on the annual greenest pixel composite) during the whole period.
netJumps_1988-2017_masked.tif is the map of the net NDVI change due to abrupt changes during the whole period.
netSlopes_1988-2017_masked.tif is the map of the net NDVI change due to gradual changes during the whole period.

jumpsCountRast_1988-2017_masked.tif is the map of the number of abrupt changes observed for each pixel during the analysed period.
slopesCountRast_1988-2017_masked.tif is the map of the number of years during the analysed period in which each pixel showed a gradual change.

To replicate the analysis, use the R code of the algorithm available at https://doi.org/10.6084/m9.figshare.23668941.v1 and the input data available at https://doi.org/10.6084/m9.figshare.23668842.v1, adjusting the time frame of the analysis.
