How does ABRP detect duplicate sites?

[chuq]

Since ABRP pulls data from a lot of locations, there will, on occasion, be sites that appear in multiple sources.

I've noticed often ABRP will recognise this and merge them, but what is the logic that is used here?

Is there a reason it doesn't merge these two locations? (both are at the exact same location as well).  The left is from my Australia charger spreadsheet, the right is from OpenChargeMap.

Hi @chuq,

We do have a method of detecting duplicates and prioritize which to display. We basically calculate a score of likeness based on how similar location, number and type of chargers, name etc. and when this score is high enough it'll be considered the same and only one will be displayed.

In this case however I cannot see why we should've chosen to display both, because as you say, the location and many other things are very much the same. We'll look into what happened.

Thanks @Katya (ABRP)

It's probably worth me mentioning that the address for one of these (the OpenChargeMap sourced one), was "Dunn Place", not "3 Davey St" up until a few days ago.  I thought this was the cause, fixed it, and waited for the daily update/import, but it didn't resolve itself even after a few days.

Hi @chuq,

We found the culprit

Apparently, as the information we got from ocm didn't list what network the charger belonged to, the overall score for likeness was when it came to the networks being the same or not, lowered. This is of course not really logical, so we adjusted things a bit and now only one will be shown.

Well that makes sense.. this station isn't really on a network yet, sorta.  It's going to use EasyPark, which is what is currently used for parking in the existing car park, but at the moment the charger itself is on free vend.  Eventually it will be integrated with EasyPark.  However there currently aren't any other EasyPark chargers in Australia, hence it not being a valid network selection in OCM!

My Australian charger spreadsheet, on the other hand, just has a free text field for the charge network.

Thanks for fixing it on the ABRP side!  I'll sort it out at OCM too.
