Bangladesh Uber H3 level 6 database
收藏资源简介:
Database for characterization of sub national units for Bangladesh using Uber H3 level 6 hexagons. Data includes crop, livestock, as well as climate data. H3 hexagons have unique identifiers that can be used to sum or average underlying data covered by area. As compared to square pixels, hexagons are better to fully cover a countries area. The lower the level used the better the fit. Data sources used: Livestock: FAO GLW (Cattle, Goats, Sheep, Chicken, Buffaloes) year 2015 Crops: IFPRI SPAM 2010, for Countries in SS Africa SPAM 2017 Climate: Worldclim 2.1 Elevation: SRTM CSI CGIAR Field Data Index H3 index level 6 bdbuffalo2 Buffaloes bdcattle20 Cattle bdchicken2 Chicken bdsheep201 Sheep bdgoats201 Goats bdhareaban banana area ha bdhareabar barley area ha bdhareabea bean area ha bdhareacas cassava area bdhareachi chickpea area ha bdhareacow cowpea area ha bdhareafoo foodcrops area ha bdhareagro groundnut area ha bdharealen lentil area ha bdhareamai maize area ha bdhareaopu other pulses area ha bdhareapig pigeonpea area ha bdhareapot potato area ha bdharearic rice area ha bdhareasmi millet area ha bdhareasor sorghum area ha bdhareasoy soybean area ha bdhareawhe wheat area ha bdhareaswp sweat potato area ha bdprecann_ annual rainfall bdtmax_ann longterm annual tmax (1970-2000) bdtmin_ann longterm annual tmin (1970-2000) bdworld250 Elevation m a.b.s.l.

采用优步(Uber)H3第6级六边形网格构建的孟加拉国次国家级单元特征数据库。数据集涵盖作物、畜牧及气候相关数据。H3六边形网格拥有唯一标识符,可用于对其覆盖区域内的基础数据进行求和或取平均运算。相较于方形像素,六边形网格能够更完整地覆盖一国全域范围,且所采用的层级越低,适配效果越好。 数据来源: 畜牧数据:联合国粮食及农业组织(Food and Agriculture Organization of the United Nations,简称FAO)GLW数据集(涵盖牛、山羊、绵羊、鸡、水牛),2015年版 作物数据:国际粮食政策研究所(International Food Policy Research Institute,简称IFPRI)SPAM 2010数据集,其中撒哈拉以南非洲国家采用SPAM 2017数据集 气候数据:WorldClim 2.1数据集 高程数据:SRTM CSI CGIAR数据集 字段 数据 索引 H3第6级索引 bdbuffalo2:水牛 bdcattle20:牛 bdchicken2:鸡 bdsheep201:绵羊 bdgoats201:山羊 bdhareaban:香蕉种植面积(公顷) bdhareabar:大麦种植面积(公顷) bdhareabea:豆类种植面积(公顷) bdhareacas:木薯种植面积 bdhareachi:鹰嘴豆种植面积(公顷) bdhareacow:豇豆种植面积(公顷) bdhareafoo:粮食作物种植面积(公顷) bdhareagro:花生种植面积(公顷) bdharealen:小扁豆种植面积(公顷) bdhareamai:玉米种植面积(公顷) bdhareaopu:其他豆类种植面积(公顷) bdhareapig:木豆种植面积(公顷) bdhareapot:马铃薯种植面积(公顷) bdharearic:水稻种植面积(公顷) bdhareasmi:粟米种植面积(公顷) bdhareasor:高粱种植面积(公顷) bdhareasoy:大豆种植面积(公顷) bdhareawhe:小麦种植面积(公顷) bdhareaswp:甘薯种植面积(公顷) bdprecann_:年降水量 bdtmax_ann:长期年最高气温(1970-2000年) bdtmin_ann:长期年最低气温(1970-2000年) bdworld250:海拔(米,相对于海平面) 注意事项: 六边形网格的尺寸可能小于SPAM等数据集的实际像素尺寸,其数值会因区位及下方覆盖像素的差异出现偏高或偏低的情况。本数据集仅可作为重要性表征指标,而非绝对数值参考。
