The data set comprises a collection of products showing the sea ice surface topography for the area of Floe 3 ice camp during N-ICE 2015 leg 5 for 24 May 2015. The surface topography is derived using photogrammetry from the series of images acquired by ICE camera setup during a survey flight on 24 May 2015. Data are presented in two resolutions on a regular 2 cm and 5 cm mesh in UTM coordinates and covers the area of about 0.81 km2 (1.7 by 0.6 km). For convenience, three different output formats are used: ascii XYZ table, GeoTiff and generic Socet GXP DTM.
Detailed documention for the data set is provided in the accompanying pdf (https://api.npolar.no/dataset/c16918e8-7f24-4131-9f02-7bcb690b594e/_file/NICE_leg5_icecamp_topography.pdf) file
