Google Maps provides the option of using an image API called StaticMap, which is essentially a still picture of coordinates displayed on a map. Using an image instead of a fully functional and interactive map decreases the load time of the page. The user first sees a map snapshot with the locations of their search results. What if the user wants to interact with the map?
Reed spent nearly a week and a half coding the coordinate clusters by writing a new algorithm that allowed the static images to mimic the dynamic functionality. It required a lot of math to figure out how to space those clusters onto the static map, which is actually a two-dimensional plane vs. the 3D dynamic plane used for globe calculations. After five tries and a few failures, he succeeded.
When you search on Spokeo for a phone number or a name, be sure to check out the map in the top left corner. Note how quickly it shows where your results are located – all thanks to Reed.
