甘肃省100米分辨率土地覆被水浇地类型数据(2005年)

甘肃省100米分辨率水浇地空间分布数据集（2005年）为2005年甘肃省水浇地空间分布。以中国1:10土地利用数据及其动态数据、与土地利用数据同期陆地卫星精纠正分县假彩色合成影像以及中国1:50万草地资源数据、1:100万土壤类型数据和1:100万植被类型数据等为数据源，在MGE和Arc/info或ArcGIS等环境下，通过专家分析和遥感自动分类相结合的方法，按照内容和区域，采用专题制图的方式完成的。

The 100-meter resolution spatial distribution dataset of irrigated cropland in Gansu Province (2005) characterizes the spatial distribution of irrigated cropland within Gansu Province in 2005. This dataset was constructed using a variety of data sources, namely China's 1:100,000-scale land use data and its dynamic change dataset, county-level precisely corrected false-color composite Landsat images synchronized with the land use data, China's 1:500,000-scale grassland resource dataset, 1:1,000,000-scale soil type dataset, and 1:1,000,000-scale vegetation type dataset. It was completed through thematic mapping based on content and regional partitioning, under the support of software environments including MGE, Arc/Info or ArcGIS, via a hybrid approach combining expert analysis and automated remote sensing classification.
