Venus. Here's a good trivia question: "Which planet is the most completely mapped?" Most people will say Earth, but Earth is 70% water and the oceans are charted, not mapped.

Magellan, a JPL-led project, used synthetic aperture radar to map Venus. Martin Marietta in Denver built the spacecraft, Hughes in El Segundo built the radar.
The main tool is Doppler radar, which can remotely measure wind speed and direction. This can be used to find rotation in a storm associate with a possible tornado. Another, recently developed tool is dual-polarized radar. Unlike conventional radar, this radar can distinguish between rain, hail, and tornadic debris.
ground clutter and evaporation are the limitations of radar maps

Venus has two artificial satellites orbiting it, radar-mapping the surface and gathering other useful information about its surface.

because a radar is stronger than a map a map can't get you through coulds it can only get you to a place
sonar devices map the sea floor, radar just boils water unless the signal is balanced ungodly.
As best as we can tell its mountains and rifts, all mapping has been done by radar.
The planet Venus was imaged using radar because its thick atmosphere makes it difficult to observe the surface using optical telescopes. Radar can penetrate the clouds and provide detailed images of the planet's surface features. Additionally, radar can also measure the surface elevation and map the topography of Venus.

They use some type of radio detection and mapping AKA Radar. They could also use a good old fashioned Lighthouse.
