“Mappr” was a combination of 2 applications, “CellSort” and “MLS-Mapper”.
CellSort History#
CellSort was originally written in PHP back in 2016/17 and was awfully slow - meaning it took about 20 minutes to pull all the cell IDs out of the MLS dataset with MCC 234 and calculate eNB / Sector IDs.
In 2020, I re-wrote the CellSort application in Java, renamed to “jcellsort” which was able to get the parsing time down, however I wasn’t the best Java dev at the time and so found it more difficult to maintain.
That bring us to the present day, with “PyCellSort” being the current implementation of CellSort. It is the fastest implementation yet, however, being written in 2021, is sorely in need of an update as my Python skills have come a long way since then.
Web-map History#
Mappr used to reside on mappr.uk, however due to pressures from uni and work, I stopped maintaining it.
Due to Mozilla Location Services shutting down, Mappr will likely not return. However I may create a historical version with the final MLS dump (not planned right now).
RIP MLS 2013 - 2024
