Hi Ashish,
Sorry, I was a bit hasty in my response earlier. I see that you are actually
trying to conditionally style features of a single resource model now. This is
also possible, but a bit trickier… I’ve managed to do this by exploiting the
“displaydescription” property. If you can include the typology information in
your description for this resource model, then you can style on the contents of
that.
For example, the following layer styles on “consultation type” in my local
database (a typological field, concept datatype, which I have added to the
description in the primary descriptor function) so that instances of type
“Post-Application” and “Condition Application” get a distinct icon (you could
add as many additional conditional icons as you desire):
{
"id": "search-results-points-markers",
"type": "symbol",
"paint": {},
"filter": [
"all",
[
"==",
"$type",
"Point"
],
[
"!=",
"highlight",
true
]
],
"layout": {
"icon-size": 1.3,
"icon-image": [
"case",
["in", "Condition Application", ["get", "displaydescription"]],
"airplane-15",
["in", "Post-Application", ["get", "displaydescription"]],
"bicycle-15",
"marker-15"
],
"icon-offset": [
0,
-6
],
"icon-allow-overlap": true
},
"source": "search-results-points"
}
I had to use the “displaydescription” field here as there is only a limited
number of fields exposed in the marker features. Hopefully that works for you!
