Crop phenology---- ground truth for crop monitoring and yield estimation

The dataset contains the ground-based observations of crop growth stages for Canada's prairie provinces (Manitoba, Saskatchewan and Alberta) from 2019 to 2020. Crop growth stages were visually observed from the side of the fields on a weekly cycle until the fields were harvested. The BBCH (Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie) scale was used to stage growth. The BBCH scale used to classify fields of canola, corn, soybean, spring wheat, peas, and barley, is described in the document “Crop Identification and BBCH Staging Manual” (Agriculture and Agri-Food Canada, 2011). The BBCH scale for Lentil is described in the document “BBCH_STAGING_MANUAL_Lentils” (Agriculture and Agri-Food Canada, 2020) Field boundaries were identified on Google Earth and verified by direct observation after the crop on each had reached an early stage of development and could be clearly distinguished from surrounding fields. When multiple stages occurred together within a field, the leading phenology was used.These survey point sources can be used to train or validate models for crop growth monitoring and yield estimation.

该数据集收录了加拿大草原省份（马尼托巴省、萨斯喀彻温省和艾伯塔省）2019年至2020年间作物生长阶段的地面观测数据。作物生长阶段通过每周一次的周期从田间侧面进行视觉观测，直至收获。采用生物联邦研究所、联邦种子管理局和化学工业联合会（BBCH）标准对生长阶段进行分类。用于油菜、玉米、大豆、春小麦、豌豆和大麦田地的BBCH标准详见《作物识别及BBCH生长阶段手册》（加拿大农业与农业食品部，2011年）。菜豆的BBCH标准则在《BBCH_STAGING_MANUAL_Lentils》（加拿大农业与农业食品部，2020年）中进行描述。田间边界在Google Earth上被识别，并在作物达到早期生长阶段且能清晰区分于周边田地后，通过直接观测进行验证。当田间同时出现多个生长阶段时，以领先物候阶段为准。这些调查点源可用于训练或验证作物生长监测和产量估算模型。
