成都平原地区秋收作物实地调查采样点分布数据(2023年)

本数据集为“成都平原地区秋收作物实地调查采样点分布数据（2023年）”，记录了2023年秋收季节主要作物样本点的地理坐标与作物类型信息。实地调查于2023年8月23日至8月31日期间开展，为确保样本数据的代表性与空间均匀性，研究区被系统性地划分为等面积网格，每个网格内布设一个样本点。实际调查过程中，根据地形与道路通行条件，对部分样点位置进行了适当调整，将样点移至道路可达位置。最终共采集247个样本点，其中水稻样本165个，玉米样本31个，田块边界样本51个。本数据集可为成都平原地区秋收作物的遥感识别、分类验证及产量估算提供基础支撑。数据以shapefile格式存储，可通过项目平台共享与下载使用。

This dataset is titled *Distribution Data of Field Survey Sampling Points for Autumn-harvested Crops in the Chengdu Plain (2023)*, which records the geographic coordinates and crop type information of sampling points for major crops during the 2023 autumn harvest season. The field survey was conducted from August 23 to August 31, 2023. To ensure the representativeness and spatial uniformity of the sample data, the study area was systematically divided into equal-area grids, with one sampling point allocated within each grid. During the actual survey, some sampling point locations were appropriately adjusted based on terrain and road accessibility conditions, and the points were moved to road-accessible positions. A total of 247 sampling points were finally collected, including 165 rice samples, 31 maize samples, and 51 field boundary samples. This dataset can provide fundamental support for remote sensing identification, classification validation, and yield estimation of autumn-harvested crops in the Chengdu Plain. The data is stored in Shapefile format and can be shared and downloaded via the project platform.
