Agricultural area by year between 1988 and 2000 in Kabul, Afghanistan

This multi-band raster dataset describes the extent of agricultural activity, including both growing and bare or fallow agricultural fields, surrounding the city of Kabul, Afghanistan for 1988 - 2020. Landsat multispectral images acquired at the height of each year's growing season were used to perform a combined vegetation and clay band ratio analysis. Each band of this raster dataset represents a single year of analysis result; Band 1 indicates agricultural area for 1988, Band 2 indicates that of 1989, and so on. Due to cloud coverage or gaps in the image record, an appropriate image was not available for nine of the years during this 32-year time period; in total 24 Landsat images were used. Band 1 indicates agricultural area for 1988, Band 2 indicates agricultural area for 1990, Band 3 indicates agricultural area for 1992, Band 4 indicates agricultural area for 1993, Band 5 indicates agricultural area for 1994, Band 6 indicates agricultural area for 1995, Band 7 indicates agricultural area for 1996, Band 8 indicates agricultural area for 1997, Band 9 indicates agricultural area for 1998, Band 10 indicates agricultural area for 1999, Band 11 indicates agricultural area for 2000, Band 12 indicates agricultural area for 2001, Band 13 indicates agricultural area for 2002, Band 14 indicates agricultural area for 2003, Band 15 indicates agricultural area for 2008, Band 16 indicates agricultural area for 2011, Band 17 indicates agricultural area for 2013, Band 18 indicates agricultural area for 2014, Band 19 indicates agricultural area for 2015, Band 20 indicates agricultural area for 2016, Band 21 indicates agricultural area for 2017, Band 22 indicates agricultural area for 2018, Band 23 indicates agricultural area for 2019, Band 24 indicates agricultural area for 2020.

本多波段栅格数据集描绘了1988年至2020年间阿富汗喀布尔市周边的农业活动分布范围，涵盖种植农田与裸露休耕农田两类。研究采用每年生长旺季获取的Landsat（陆地卫星）多光谱影像，开展植被与黏土波段比值联合分析。该栅格数据集的每个波段对应单一年度的分析结果：波段1代表1988年的农业区域，波段2代表1989年的农业区域，依此类推。受云层覆盖或影像记录存在缺口影响，在这32年的时间跨度内，有9个年份未能获取合格影像，最终共使用24景Landsat（陆地卫星）影像。波段1对应1988年农业区域，波段2对应1990年农业区域，波段3对应1992年农业区域，波段4对应1993年农业区域，波段5对应1994年农业区域，波段6对应1995年农业区域，波段7对应1996年农业区域，波段8对应1997年农业区域，波段9对应1998年农业区域，波段10对应1999年农业区域，波段11对应2000年农业区域，波段12对应2001年农业区域，波段13对应2002年农业区域，波段14对应2003年农业区域，波段15对应2008年农业区域，波段16对应2011年农业区域，波段17对应2013年农业区域，波段18对应2014年农业区域，波段19对应2015年农业区域，波段20对应2016年农业区域，波段21对应2017年农业区域，波段22对应2018年农业区域，波段23对应2019年农业区域，波段24对应2020年农业区域。
