| | 113 | Among these new extensions there is a set of new addons to import and pre-process Copernicus Sentinel 2 imagery: G7A:i.sentinel.preproc and G7A:i.sentinel.mask. These two modules which add up to the existant G7A:i.sentinel.download and G7A:i.sentinel.import, were contributed by a student under Google Summer of Code 2018 program. With all these Sentinel related modules GRASS GIS provides now the possibility to create full workflows that include download, import, atmospheric correction and cloud masking of Sentinel 2 imagery. Additional imagery addons include, G7A:i.pysptools.unmix for extracting endmembers and spectral unmixing using [https://pysptools.sourceforge.io/ pysptools] and a set of G7A:i.signature tools to list, copy and remove signature files. Moreover, a new set of addons for artificial neural networks was also developed, G7A:i.ann.maskrcnn, to perform supervised classification using convolutional neural networks. |

| | 117 | Some other new addons include: |
| | 118 | * G7A:d.vect.colhist to draw an histogram from values in a vector attribute column |
| | 119 | * G7A:r.accumulate to calculate weighted flow accumulation, stream networks, and the longest flow path using a flow direction map |
| | 120 | * G7A:r.connectivity to perform connectivity analysis of ecological networks |
| | 121 | * G7A:r.estimap.recreation which is an implementation of the ESTIMAP algorithm to support mapping and modelling of ecosystem services |
| | 122 | * G7A:r.in.pdal to import LAS LiDAR point clouds data and create a raster map out of it |
| | 123 | * G7A:v.rast.bufferstats to calculate statistics of raster map(s) for buffers around vector geometries |
| | 124 | * G7A:v.what.strds.timestamp to upload strds values to the attribute table at positions of vector points in space and time |
