The Generalized Normalised Difference Vegetation Index (GNDVI) is a modification of the Normalised Difference Vegetation Index (NDVI), which has been proposed by Weicheng Wu (2014) for the assessment of dryland environments due to the inadequacy of the NDVI in these areas. The Generalised Normalised Difference Vegetation Index (GNDVI) 2019 highlights the effects of the Government of Ghana's fight against illegal mining on vegetation and 'blue mining'. These data can be used to monitor the health of vegetation before and after the fight against galamsey. Further, the data can be used to assess the success or failure of the combat against dessertation initiative of the government of Ghana in the Northwest region as against its approval for large-scale industrial mining in the same area EPSG:3857
