Author: MapScaping December 7, 2022 Duration: 43:52
FROM THE ARCHIVE!   Calculating the location of your mobile device ( the blue dot ) is not as straightforward as you might imagine. It involves databases of wifi hotspots, 3D city models, IMU's, GNSS, your proximity to cell towers, and maybe something called visual positioning. Ed Parsons - Googles Geospatial Technologist explains    previous podcast episode that you might enjoy! SATELLITE-BASED AUGMENTATION SYSTEM - A BASE STATION IN THE SKY POSITIONING AS A SERVICE AND THE ROLE OF SMARTPHONES IN THE FUTURE OF GEOLOCATION USING THE GEOMAGNETIC FIELD OF BUILDINGS TO NAVIGATE INDOORS HYPER-ACCURATE INDOOR LOCATION NAVIGATING THE PAST, PRESENT AND FUTURE OF GNSS   Happy to connect with you on LinkedIn https://www.linkedin.com/in/danielodonohue/ Or Twitter https://twitter.com/MapScaping  

The MapScaping Podcast delves into the intricate world where geography meets data. This isn't about static paper maps, but the dynamic, digital systems that help us understand our planet. Each conversation focuses on the practical and the visionary within GIS, geospatial technology, remote sensing, and earth observation. You'll hear directly from the cartographers, data scientists, software developers, and analysts who are building the tools and interpreting the information that defines modern digital geography. The discussions explore how satellite imagery is used, how location intelligence solves complex problems, and where the technology is headed next. For professionals, students, or anyone fascinated by how we chart and comprehend our world, this podcast offers a grounded look at a field that is constantly redrawing its own boundaries. Tune in to The MapScaping Podcast for insights that are as much about the people and ideas shaping this space as they are about the technology itself. It's a consistent source for those who think spatially, providing depth and context that goes beyond the software interface. Listen to find out how the hidden structures of geospatial data influence everything from urban planning and environmental conservation to business logistics and everyday apps.
