JSMARS Planetary WebGIS

JavaScript Mission-planning and Analysis for Remote Sensing

JSMARS is an open-source, browser-native planetary geographic information system (GIS) developed by Dr. M. Anwar Sounny-Slitine. Built with pure ES Modules and zero build step, it provides instant access to planetary cartography, elevation profiles, 3D WebGL terrain, and scientific modeling across Mars, the Moon, Earth, and Europa without heavy desktop installations.

Inspired by the JMARS desktop application developed by Arizona State University's Mars Space Flight Facility.
