[Koha-devel] ElasticSearch Geoserch

[dcook at prosentient.com.au]

I don't think the link is working for me, but it's an interesting idea. 

Where in the bib record are you storing the coordinate data? Have you looked at https://www.loc.gov/marc/bibliographic/bd034.html? It looks like that field was redescribed in 2021 to perfectly suit your use case.

In terms of feasibility, I think the main change would be to add suitable indexes for 034 MARC21 data. Beyond that, I think a plugin would make the most sense for a frontend, as the geosearch would probably be fairly specific to your library's needs. But if you could think of a geosearch that is useful for other libraries as well, then I imagine it could make it into Koha. 

I don't know if any of my libraries would use it, but it's interesting. It might be one of those things that people don't know that they want until after they see it in action? 

Anyway, sounds cool!

Betreff: [Koha-devel] ElasticSearch Geoserch

Hi!

We are currently discussing a project where a customer wants to add a geosearch to Koha (store lat/lng in biblio, use Elastic geo queries [0] together with a leaflet.js map to find biblios in a certain area).

I assume that might be of interest to Koha in general?

I also assume that this will only be possible via some changes to Koha core code (i.e. adding a new search field to ES and Koha, define mappings), while some things might be doable as a plugin (the "frontend"
map etc).

Before we start hacking I'd like to get some feedback from you:

* Would something like this be considered to be added to future Koha
  versions?
* Do you think it's feasable / possible to add to Koha?
* Has anybody maybe done a geosearch before? (I couldn't find
  anything..)

Greetings,
domm
