Multispectral UAV imagery and land cover maps of tundra rangeland in north-eastern Iceland, Aug-Sep 2021



This data was collected using a DJI P4 Multispectral drone near Þórshöfn in Iceland during the late growing season of 2021. The imagery has been processed using Pix4D software. The images are radiometrically corrected using a Mapir reflectance target during the survey. 6-8 ground control points were collected using a Spectra Precision ProMark 120 GPS system with HMRS/VMRS = ~0.5 m error. 12x orthomosaics were generated and resampled to 5 cm spatial resolution and cut to a 300x300 m area extent per site. This dataset includes 6 orthomosaics per site: red, green, blue, red-edge, near-infrared and ndvi band in geotiff format. 12x land cover maps were classified using Random Forest supervised classification. In the land cover layer, the following numbers correspond to: 1 = barren, 2 = low-stature vegetation, and 3 = medium-stature shrub cover. The training and validation data was collected in the field and derived from high-resolution orthomosaics.

Further information about the survey metadata and the processing details is available in the publication where the data was used.
