BEDMAP3 - Ice thickness, bed and surface elevation for Antarctica - standardised data points

We present here the Bedmap3 ice thickness, bed and surface elevation standardised CSV data points that are used to create the Bedmap3 gridding products in addition to the previous data releases. The data consists of 50 million points acquired by 17 different data providers in Antarctica. The associated datasets consist of: - Bedmap1 standardised CSV data points: https://doi.org/10.5285/f64815ec-4077-4432-9f55-0ce230f46029 - Bedmap2 standardised CSV data points: https://doi.org/10.5285/2fd95199-365e-4da1-ae26-3b6d48b3e6ac - Bedmap3 statistically-summarised data points (shapefiles): https://doi.org/10.5285/a72a50c6-a829-4e12-9f9a-5a683a1acc4a This work is supported by the SCAR Bedmap project and the British Antarctic Survey's core programme: National Capability - Polar Expertise Supporting UK Research

本研究公开了冰图3（Bedmap3）的冰厚、冰床与地表高程标准化逗号分隔值（CSV）数据点，此类数据可用于生成冰图3网格化产品，且除过往发布的数据外，还包含了本次公开的数据集内容。该数据集包含由17家不同数据提供商在南极地区采集的5000万个数据点。配套数据集如下：
- 冰图1（Bedmap1）标准化逗号分隔值（CSV）数据点：https://doi.org/10.5285/f64815ec-4077-4432-9f55-0ce230f46029
- 冰图2（Bedmap2）标准化逗号分隔值（CSV）数据点：https://doi.org/10.5285/2fd95199-365e-4da1-ae26-3b6d48b3e6ac
- 冰图3统计汇总数据点（形状文件shapefiles）：https://doi.org/10.5285/a72a50c6-a829-4e12-9f9a-5a683a1acc4a
本研究得到了南极研究科学委员会（Scientific Committee on Antarctic Research，简称SCAR）冰图项目以及英国南极调查局核心项目“国家能力——支撑英国科研的极地专业服务”的资助。
