- Equal Earth projection — The Equal Earth map projection is a new equal-area pseudocylindrical projection for world maps jointly developed by Bojan Šavrič (Esri), Tom Patterson (US National Park Service), and Bernhard Jenny (Monash University). It was created to provide a visually pleasing alternative to the Gall-Peters projection, which some schools and socially concerned groups have adopted out of concern for fairness. Their priority is to show developing countries in the tropics and developed countries in the north with correctly proportioned sizes.

Data Sources
Catalogs for look up specific data
- United States Interagency Elevation Inventory — The U.S. Interagency Elevation Inventory is a comprehensive, nationwide listing of known high-accuracy topographic and bathymetric data for the United States and its territories.
- Earthdata — NASA promotes the full and open sharing of all its data to research and applications communities, private industry, academia, and the general public. In order to meet the needs of these different communities, NASA’s Earth Observing System Data and Information System (EOSDIS) has provided various ways to discover, access, and use the data.
- Earthdata Data Recipes — Data recipes are tutorials or step-by-step instructions that have been developed by the Earth Observing System Data and Information System (EOSDIS) Distributed Active Archive Centers (DAACs) staff or EOSDIS systems engineers to help users learn how to discover, access, subset, visualize and use our data, information, tools and services. These recipes cover many different data products across the Earth science disciplines and different processing languages/software.
- TopoView — TopoView highlights one of the USGS's most important and useful products, the topographic map. In 1879, the USGS began to map the Nation's topography. This mapping was done at different levels of detail, to support various land use and other purposes. As the years passed, the USGS produced new map versions of each area. TopoView shows the many and varied topographic maps of each of these areas through history. This can be particularly useful for historical purposes, such as finding the names of natural and cultural features that have changed over time.

The functional interface to MOAB is simple yet powerful, allowing the representation of many types of metadata commonly found on the mesh. MOAB is optimized for efficiency in space and time, based on access to mesh in chunks rather than through individual entities, while also versatile enough to support individual entity access. The MOAB library can naturally represent finite element and other types of mesh data [1]. Various types of meta-data are often used in conjunction with a mesh. Examples include boundary condition groupings, material types, and provenance information for the mesh. Because the data model used in MOAB is so abstract, conventions are useful for describing how meta-data is stored into that data model."
