Seminario: Google Geo: How to Provide the Freshest and Most Accurate Photogrammetric Reconstruction of the Earth Surface at a Global Scale

Dentro del Máster Universitario en Robótica, Gráficos y Visión por Computador, el próximo jueves día 19 de septiembre a las 14 horas  Faraz Mirzaei impartirá el seminario Google Geo: How to Provide the Freshest and Most Accurate Photogrammetric Reconstruction of the Earth Surface at a Global Scale.

Será en el aula A.07 del Ed. Ada Byron

 

Abstract: In this talk, I will overview our work at Google Geo to get global maps available to a wide range of users on their phones, through the web, or through the Google Earth Engine APIs. I will discuss the high level journey from raw imagery to photogrammetric reconstruction. I will discuss algorithmic challenges involved in quantifying, measuring, and achieving high accuracy modeling of the surface of the Earth.

I will provide a brief introduction to frames of references, International Terrestrial Reference Frame (ITRF), measurement epoches, earth ellipsoid and geoid, tectonic shifts, earthquakes, subsidence (like CA central valley), and earth tides. And how each of these pose a challenge in estimating a fresh topographic map of the Earth’s surface.
