100 billion Points Every Day 100 billion is a very large number, let's say that I gave you a spreadsheet with 100 billion rows in it, each row consisted of five columns Latitude, Longitude, Device ID, A Timestamp, and a column telling the name of the data provider What would you do with that?  How would you clean it? Make sense of it? Extract value from it? What would people use it for? And how would you do this in a way that could be systematized? FourSquare does this every day with the help of something they call a movement engine. To help understand more about how they do this I have invited Gabriel Durkin the director of data science on the podcast. This is the last in a series of episodes I have worked on together with FourSquare and I have to say it's been really enjoyable working with them.  If you are interested in hearing some of the previous episodes just check out the links below!   From Pixels To Patterns AI In Spatial Analysis https://mapscaping.com/podcast/from-pixels-to-patterns-ai-in-spatial-analysis/ Big Data In The Browser https://mapscaping.com/podcast/big-data-in-the-browser/ Spatial Knowledge Graphs https://mapscaping.com/podcast/spatial-knowledge-graphs/ Designing For Location Privacy https://mapscaping.com/podcast/designing-for-location-privacy/ All Of The Places In The World https://mapscaping.com/podcast/all-of-the-places-in-the-world/ Geospatial Jobs   There are a few new jobs on our Job Board!

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.
