We present here the Bedmap1 ice thickness, bed and surface elevation standardised CSV data points that were used to create the Bedmap1 gridding products. The data consists of 2 million data points acquired in Antarctica from 1960s to 2000. The associated datasets consist of: - Bedmap2 standardised CSV data points: https://doi.org/10.5285/2fd95199-365e-4da1-ae26-3b6d48b3e6ac - Bedmap3 standardised CSV data points: https://doi.org/10.5285/91523ff9-d621-46b3-87f7-ffb6efcd1847 - Bedmap1 statistically-summarised data points (shapefiles): https://doi.org/10.5285/925ac4ec-2a9d-461a-bfaa-6314eb0888c8 This work is supported by the SCAR Bedmap project and the British Antarctic Survey's core programme: National Capability - Polar Expertise Supporting UK Research ... : The primary source data consist of survey point measurements of ice thickness, bed elevation and surface elevation, which principally comes from airborne radar surveys and seismic soundings, and to a smaller extent from ground-based radar surveys. All the data have been standardised to a specific CSV format. The format consists of (i) an extended header section where (a) each line is introduced by a comment ("#") character, (b) each line contains a single header item, (c) the colon character (":") is used as the key/value separator, (d) units are in parentheses, (e) attributes preferably use a common vocabulary such as the CF convention and includes attributes from the ACDD; (ii) a header row composed of the column name following the CF convention and units in parentheses; and finally (iii) the data using comma as the separator. The extended header consists of general information regarding each campaign such as the year, the name of the main investigator, funding and processing details. The variable names ...
