Title

Gro for GooD Land Cover Land Use Data 1990 & 2015, Kwale County, Kenya (NERC grant NE/M008894/1)

Abstract

This data set contains land cover/land use data for the year 1990 and 2015 obtained through processing of Landsat images of US Geological Survey. These data sets were obtained through a supervised classification carried out with Landsat 8 image for 2015; Landsat 4 and 5 were used for land use classification of 1990.

Quality and validity

Lineage

Imagery used in the analysis was downloaded from the Earth Explorer USGS image database (Landsat Imagery Archive). A number of images for the 1990 land cover were combined i.e. 1992, 1991, 1995 and small section of 1997. This was done for cloud removal purposes alongside cloud cover removal algorithms applied for areas with less than 50% cloud cover. Cloud cover was not a major problem for 2015 images. Landsat 166063 was used for the classification for the years mentioned above. Image pre-processing procedures; cloud cover removal using the assessment cloud cover algorithm mosaicking of different images as cloud removal tools was applied. The images were set to WGS84 UTM zone 37s. [See Landuse landcover methodology.txt file within the zip data set for further details]
