Dataset: Geographical distribution and reed cover of Hungarian fishponds

The data is organized in the following folders: Folder: - “Fishpond_points_HU”: contains the MS Excel file “FP_HU.xlsx” with the coordinates (latitude and longitude) as well as the shapefile “FP_HU.shp” for the fishpond farm locations in Hungary. - “Fishpond_poly_HU”: contains the polygon shapefile for the boundaries of the fishponds - “Reed_Cover_FP_HU”: contains GeoTIFF images for the reed cover present inside the fishponds. The reed cover was mapped by applying the NDVI thresholding method on Sentinel 2 imagery for all seven NUTS2 regions of Hungary from the year 2017 – 2021. The year-wise classified reed cover images can be found in the sub-folders namely: “CH” – Central Hungary, “NH” – Northern Hungary, “CTD” – Central Transdanubia, “STD” - Southern Transdanubia, “WTD”- Western Transdanubia, “SGP” – Southern Great Plain and “NGP” – Northern Great Plain. In order to replicate the study, the Google Earth Engine (GEE) script is also provided in this database.

本数据集按以下文件夹结构组织：
- 「Fishpond_points_HU」：内含匈牙利养鱼场点位的经纬度坐标微软Excel（Microsoft Excel）文件「FP_HU.xlsx」，以及对应点位的矢量形状文件（shapefile）「FP_HU.shp」。
- 「Fishpond_poly_HU」：内含渔场边界的多边形矢量形状文件（shapefile）。
- 「Reed_Cover_FP_HU」：内含渔场内部芦苇覆盖范围的GeoTIFF影像（GeoTIFF）。该芦苇覆盖范围通过对2017至2021年匈牙利全部7个NUTS2级区域的Sentinel 2影像（Sentinel 2）应用归一化差异植被指数（Normalized Difference Vegetation Index，NDVI）阈值法绘制得到。按年份分类的芦苇覆盖影像存储于如下子文件夹：「CH」——匈牙利中部（Central Hungary）、「NH」——匈牙利北部（Northern Hungary）、「CTD」——中多瑙河大区（Central Transdanubia）、「STD」——南多瑙河大区（Southern Transdanubia）、「WTD」——西多瑙河大区（Western Transdanubia）、「SGP」——南大平原（Southern Great Plain）、「NGP」——北大平原（Northern Great Plain）。为便于研究复现，本数据库中同时提供了Google Earth Engine (GEE)脚本。
