Get GMED Layers

All the GMED environment layers are available for download individually or as a combined group based on the dataset classification. Presently the only layers which conform with the data quality standard are made available for download. We will enable unavailable layers for download once the post-processing is complete. Unless your work involved polar regions (especially the regions above 70°N), cropping the dataset with maximum 70°N as top extent is recommended as many source layers have interpolation errors above this latitude due to unavailability of primary survey data. A cropped version of GMED dataset is also available for download from this page.
