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

本文发布Bedmap3冰厚、冰床与表面高程的标准化逗号分隔值（Comma-Separated Values，CSV）数据点，除过往公开数据版本外，该类数据还可用于生成Bedmap3网格化产品。本次数据集包含由17家不同数据提供商在南极地区采集的5000万个数据点。关联数据集包含以下内容：
- Bedmap1标准化CSV数据点：https://doi.org/10.5285/f64815ec-4077-4432-9f55-0ce230f46029
