Before smartphones, digital mapping was just a desktop experiment. Discover how a scrappy startup evolved into a global lens using AI and 360-degree tech.
It’s a classic engineering trade-off—perfection versus progress. Google operates on this principle of just getting started and iterating later rather than sitting in a boardroom debating the perfect way to do it for years.
History of google maps and how street view works
The project began with a GIS expert building a prototype in just two weeks that featured 360-degree video captured from a camera hanging under a helicopter. Before it became a polished product, Google co-founder Larry Page personally drove around the San Francisco Bay Area with a camcorder to test if building facade footage would be useful. By 2007, the first official fleet consisted of SUVs outfitted with cameras, lasers, and GPS units, with trunks full of computers to prove that users wanted to see a street before arriving at their destination.
Google has adapted its technology to various environments using a diverse range of "vehicles." For snowy terrain like the 2010 Winter Olympics or ski resorts, they used modified snowmobiles. To navigate pedestrian zones and narrow urban areas like Stonehenge, they developed the "Trike," a three-wheeled bicycle. For hiking trails and desert dunes, they utilized the "Trekker" backpack and even strapped cameras to camels. Additionally, they used underwater apparatuses to map the Great Barrier Reef and a pushcart called the "Trolley" to capture the interiors of museums and the International Space Station.
Before any imagery is made public, it undergoes a compute-intensive processing step to detect and blur faces and license plates. This system has been in development since 2008 and currently uses a sophisticated combination of a "sliding-window" detector and a fast post-processor to ensure high accuracy. The automated system successfully blurs approximately 89% of faces and 94% of license plates. In cases where the technology misses a detail or over-blurs an object, users can flag the image for manual review by Google’s team.
Street View creates an immersive experience by building a low-resolution depth map for every panorama. Newer imagery uses laser scanners to measure the distance to surfaces like buildings and roads, creating a 3D mesh. For older imagery captured without lasers, Google uses a computer vision technique called "optical flow," which analyzes how objects move across the screen as the car drives by to calculate depth. When a user moves their cursor, the app stretches the 2D photos over this 3D model, making it feel like the user is walking through a physical space rather than just looking at a flat image.
Immersive View is a living 3D model of a city rather than a static photo. It uses AI and "neural radiance fields" to fuse billions of Street View and aerial images into a volumetric representation. This technology allows the map to simulate real-time conditions, such as changing the lighting based on the actual weather and time of day or showing the current "busyness" of a restaurant. It also enables "Immersive View for routes," which allows users to fly through their entire planned journey in a 3D environment before they start driving.

En serio, todavía no he explorado la app a fondo, pero después de usarla estos últimos días estoy impresionadísima… BeFreed está en otro nivel comparada con cualquier otra app de aprendizaje que haya usado. Te engancha muchísimo y de verdad mejora la concentración, ¡ideal para los que no paran de hacer scroll!
@ladyInfinity
Compré BeFreed hace exactamente 23 días y lo he usado todos los días desde entonces. Se ha integrado por completo en mi rutina diaria de trabajo y aprendizaje.
@jayallen
La verdad es que la app ha superado todas mis expectativas. Puedo pedirle que genere audio sobre cualquier tema, sea cual sea, y el resultado es impresionante. Mi campo profesional es una especialización en psicoterapia y es multidisciplinario; aun así, las respuestas son muy precisas.
@Raguipa
Lo que más valoro es cuánto ha reducido mi scroll: paso menos tiempo buscando y más tiempo absorbiendo información. La combinación de audiolibros completos, podcasts y los planes de aprendizaje es brillante.

Llevo 24 años siendo instructor de aprendizaje acelerado PhotoReading… los libros, la lectura y el aprendizaje son lo mío, y BeFreed ha hecho un gran trabajo ofreciendo un enfoque innovador para transmitir información de una forma fácil de consumir.
@BeFreed user
No es solo una app de resúmenes de libros: he usado la opción de lectura divertida y es un resumen mucho mejor y una forma más fácil de captar las ideas que la manera tradicional; solo eso ya vale la pena.
@austinakon
Me encanta esta app. La he usado varios días y no puedo dejar de escuchar. Una forma buenísima de empezar.
@jcrules328
Me gusta mucho el programa; llevo alrededor de un mes probándolo y siento que es una verdadera joya. Funciona genial porque puedo usar BeFreed para crear mis propios temas, y la voz es buenísima, con opciones de narración ilimitadas.
@DanielCZ
Me encanta poder recibir información e ideas útiles y condensadas en un audio estilo podcast de 8 a 15 minutos. No soy muy fan de los podcasts por tanto relleno, pero esto va directo al grano.
@BeFreed user
Estoy terminando mi doctorado y tengo que leer muchísimo material desconocido… Con BeFreed simplemente escribes un prompt y la app encuentra las fuentes por ti y genera un podcast en audio. El proceso de BeFreed me parece más ágil que el de NotebookLM.
@Brad
Suelo buscar en YouTube algo que escuchar mientras preparo el desayuno, salgo a caminar o voy al trabajo, ¡y BeFreed ofrece un enfoque aún más certero, sin anuncios y sin relleno!
@BeFreed user
Lo mejor de esta plataforma es su versatilidad. Literalmente no hay tema que quede fuera. Le lanzas lo que sea y lo maneja… Es raro encontrar una herramienta de aprendizaje sin limitaciones que de verdad cumpla lo que promete.
@jayallen
BeFreed es fantástica. Su diseño intuitivo hace que pase menos tiempo navegando y más tiempo aprendiendo. La mezcla de audiolibros, podcasts y planes de aprendizaje es una combinación genial que ha cambiado por completo mi rutina diaria.
@BeFreed user
Al principio me llevó un rato entender cómo crear podcasts en italiano y ¡boom! ¡Es genial! Puedo pedirle que me explique cualquier tema y lo hace súper bien y con mucha inteligencia.
@matteo77
BeFreed se ha convertido en mi app diaria de audiolibros… Lo que más me gusta es que pones tu texto y te devuelve un audio que puedes escuchar donde sea.
