Re: [API-users] Multiple taxonKey values with maps API ?

13 Aug 2018

      Hi
I tried simply concatenating vector tiles, this is supported by the 
protocol but only works if the layers have different names. The layer 
for these tiles is always "occurrence", so it doesn't quite work.
https://labs.gbif.org/~mblissett/2018/08/concatenate-vector-tiles/ has a 
hack to make this work, but it's probably just as easy to add multiple 
layers to a map.

Okay, sounds good, I will not use them.

I’d advise against using the “adhoc” maps.  They are incredibly
slow and anything beyond small load really causes issue. A loop
within an R script will likely kill the server.

We are exploring alternatives (elasticsearch based) but it will be
a while before ready.

Thanks

Thanks Tim/Matt,

Right, the BOTH example is what I'm looking for. Great, didn't
realize that adhoc would work!  The use case is this WIP project
https://github.com/ropensci/phylodiv where the idea is to let
users quickly visualize biodiversity of taxa of a phylogeny (e.g.,
comparing clade A vs. B, species A vs. B, genus X vs. genus Y,
etc.), and there's a lot more possible user questions I can handle
if I can include multiple taxa in a map API query.  So I think
adhoc may be fast enough to give users that quick response they'd
need for exploring many questions quickly (much faster than
downloading full occurrence data, and just a bit slower than
density maps).

Best, Scott

    Hi,

    Mackrel:
    http://api.gbif.org/v2/map/occurrence/density/0/0/0@1x.png?srs=EPSG:4326&bin=hex&taxonKey=8596&style=purpleYellow-noborder.poly

    Both:
    http://api.gbif.org/v2/map/occurrence/density/0/0/0@1x.png?srs=EPSG:4326&bin=hex&taxonKey=5231190&taxonKey=8596&style=purpleYellow-noborder.poly

    I think the both example is what Scott's asking for, and it
    isn't supported
    <https://github.com/gbif/maps/blob/master/vectortile-server/src/main/java/org/gbif/maps/resource/Params.java#L69>.

    It /is/ supported with an ad-hoc search, but these are usually
    much slower:
    http://api.gbif.org/v2/map/occurrence/adhoc/0/0/0@1x.png?srs=EPSG:4326&bin=hex&taxonKey=5231190&taxonKey=8596&style=purpleYellow-noborder.poly

    I've made an issue for it:
    https://github.com/gbif/maps/issues/27
    <https://github.com/gbif/maps/issues/27> since it's not the
    first time this has been requested. The previous request was
    for different colours to be applied to each taxon, which is
    more complicated and different to just adding several taxa's
    occurrences together.

    Cheers,

    Matt

        I’m not sure if this went unanswered but the API has
        supported that since the beginning Scott.

        Or have I misunderstood something?

        API ?

        Hello!

        Are there any plans to allow passing any of the primary
        parameters (taxonKey, datasetKey, country, publishingOrg,
        publishingCountry) more than once. e.g.

        ...?taxonKey=1&taxonKey=2

        or comma separated. Perhaps up to some max number?

        Or is there a good reason not to suppor that? Woud it lead
        to jobs that run too long on your servers?

        Thanks! Scott
