Hydrography90m: A new high-resolution global hydrographic dataset

In tandem with the monumental increase in geo-data availability from remote sensors, field sensors and various publicly available environmental datasets, state-of-the-art geoinformatics algorithms have evolved to harness earth science data as never before. In the field of computational hydrology, these processes have yielded global information in fine detail, and of exceptional precision.
