Google Earth Pro

Google Earth Pro is an incredibly famous, visually staggering, and wildly accessible geospatial platform that completely revolutionized the way humanity views the planet. Originally a highly expensive enterprise tool ($399/year), Google famously made the "Pro" version 100% free, unleashing incredibly powerful, high-resolution satellite imagery and lightweight GIS tools to everyone on earth. The absolute core superpower of Google Earth Pro is its "Historical Imagery and Unparalleled 3D Global Visualization." A civil engineer or a real estate developer can type in an address, fly there in 3D, and instantly use the "Historical Imagery" slider to see exactly how a plot of land changed over the last 20 years. They can easily measure polygons (area) and lines (distance) with a few clicks. While it lacks the massive, mathematical geo-processing power of ArcGIS or QGIS (you wouldn't use it to run complex regression analysis on crime data), it is the absolute global standard for rapid visual site surveying, creating KML files, and exporting high-resolution map images for reports. For journalists, real estate developers, and educators needing instant, high-fidelity visual context of any location on earth, it is legendary.
