Created May 2017We have bought over a thousand pounds of equipment (including a significant donation from two members) to allow members to make their own full spectrum bat recordings in Bedfordshire and get a GPS location at the same time
This will allow members to make their own recordings. Those lacking the necessary sonogram expertise can return these recordings and others in the bat group can analyse them. We are using the Peersonic bat detector,
Danny spent the winter writing a program to make the analysis of data smpler the program also accepts data from a Griffin and the Echometer touch .
The program links the GPS data with the data from the bat detectors. We hope this will appeal to members who don’t come out to group events and give us records in areas we have not been to.
The next stage involved humans identifying the bats present. Then the program tidies up the data making it easy to produce a QGIS map and gives us a species list.
The map below shows the results from a survey one cold evening in April 2017..

Update October 18th
The map below shows the data we collected from Mid April to the end of September, This in not a complete reord as folk are still analysing their rfesults. The map only gives the location of bats, it does not give species. About 20 of the ba group got involveed., and we have analysed nearly 40,00 files so far.

If other bat groups would like a copy of the Pinpoint Bat Program (This will be unsupported), please get in touch. NB this program does not do Auto ID but it sure speeds up the process.
