We are working very hard to process new data and make it viewable on the map as quickly as possible. Scaling and adding new features to the site makes this more difficult but this is a top priority.
Currently the database of cell phone tower locations is updated about once every week or every two weeks. Its done manually and thats painful. The cellular heatmaps are updated much less frequently. It represents a bigger challenge as the amount of processing power required to create the maps is non trivial and there are many kinks to work out.
The good news: We have technical challenges to work out but have made good progress. We hope over the next few weeks to massively decrease the time it takes new cell phone towers to appear on the map with the not to distant goal of making this daily.
Heatmaps, by nature, are more difficult as every new point that comes in would require recalculation of our averages and thus each image tile needs to be re-processed. Each zoom has 2^n image tiles, so as you get past a zoom level of around 10, thats already a million images… We’re working on it though
Also, the stats on our homepage are updated every 60 minutes!
