Using Redis for Storing and Working with Geospatial Data

Working with geospatial data is notoriously difficult, because latitude and longitude are floating point numbers and should be very precise. In addition, it would seem that latitude and longitude can be represented as a grid, but in fact they can't, simply because Earth is not flat, and mathematics is a complex science. In this article, we'll look at how Redis can help us minimize calculations when working with geospatial data.
