GTOPO30 is a global raster digital elevation model (DEM) providing terrain elevation data with a horizontal grid spacing of 30 arc seconds, approximately 1 kilometer. The dataset was completed in late 1996 after a three-year collaborative effort led by the U.S. Geological Survey's EROS center, with contributions from NASA, UNEP, and other international agencies. It was derived from multiple raster and vector topographic sources and is distributed in tiled files for easier access.
A global pattern of 1964 map tiles, each approximately 5 by 5 degrees, provides VNIR hyperspectral mapping data of the Martian surface. The dataset contains Lambert albedo images, summary products, and augmented DDR data, organized into 30 subdirectories by Mars Chart. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.
A 2020 polygon dataset of non-authoritative management zones for inscribed UNESCO World Heritage Sites in Myanmar, specifically Bagan and Pyu Ancient Cities. The dataset was digitized in medium scale by CDE Myanmar based on georeferenced, publicly available reference maps. It is provided by the Myanmar Information Management Unit (MIMU) and was last updated in March 2026.
Surface measurements from the Indian Ocean and Mozambique Channel were collected aboard the R/V Marion-Dufresne from April 4 to April 30, 2019. The data includes dissolved inorganic carbon, total alkalinity, temperature, and salinity, aimed at evaluating the impact of global warming and acidification on coral reef ecosystems in the Eparses Islands. This discrete, time-series data supports research on ocean carbon cycles and the health of vulnerable marine habitats.
222 countries worldwide are coded for democracy from 1800 to 2015. The data set provides a dichotomous classification and includes an updated measure requiring a sufficient level of female suffrage. It was created by Carles Boix, Michael K. Miller, and Sebastian Rosato, with the original version published in 2013.
Oceanographic profile data from the Australian OZGOFS/JGOFS research project, comprising three cruises in the western equatorial Pacific Ocean. The dataset includes high-resolution CTD profiles and bottle sample measurements for temperature, salinity, nutrients, chlorophyll-a, and other parameters. Data was collected by the R.V. Franklin across three expeditions between October 1990 and November 1993.
Geoscience Australia's Marine Samples Collection contains seabed samples gathered since the 1950s. The collection includes shallow cores, rocks from dredging, and sediments collected via grab and dredge methods, with a large proportion refrigerated.
AUSTopo digital map series provides topographic coverage of Australia at a 1:250,000 scale, comprising 516 standard maps. Each map covers approximately 150 km east-west and 110 km north-south, depicting natural and constructed features. The series is produced by Geoscience Australia.
A collection of skin cancer images intended for deep learning classification tasks. The dataset is described as balanced across multiple classes. It was sourced from Kaggle, but the author, organization, and specific collection details are unknown.
