You can even listen to the sounds of the rover if you stand close by, but please don't touch it—otherwise you would contaminate the probes."
The map allows virtual hikers to zoom in and out, and pan rapidly across scenes, so that they can explore the landscape from large scales down to centimeter-detail. Some of the 360° panoramas integrated with the waypoints have been synthetically rendered from orbital image data.

Others are real panoramas stitched together from a multitude of single images taken by the Mastcam-Z camera instrument onboard the Mars 2020 Rover Perseverance, which have been provided by the University of Arizona. The sounds have been recorded by the SuperCam instrument on that same rover mission.
The base layer of the map is a merged dataset derived from three different instruments currently orbiting Mars: the HRSC on Mars Express, and the Context Camera (CTX) and High Resolution Imaging Science Experiment (HiRISE) instruments on Mars Reconnaissance Orbiter (MRO). The HiRISE data has been provided by provided by the Terrain Relative Navigation (TRN) team of the Jet Propulsion Laboratory (JPL).
The Jezero map builds on the data portal of the High Resolution Stereo Camera (HRSC) instrument of ESA's Mars Express mission, which provides tools to visualize and disseminate large amounts of Mars images and terrain data in an online environment.
"Initially we created the Jezero map as an outreach application to complement the HRSC Mapserver tool, which supports professional scientists to explore the Martian surface," said Sebastian Walter. "But as the rover returns more and more high-resolution image data and even audio recordings, it turns out to be the perfect tool for immersive visualization of that data in a scientific context by itself."
