Get Collection Items

GET
/collections/{dataset_id}/items
 
curl --request GET \
  --url 'https://example.com/collections/2489E9AD-2EE2-8E00-8EC9-32D5F69181C0/items?limit=10&offset=0&include_geometry=true'

OGC API Features items endpoint — returns GeoJSON FeatureCollection for a dataset.

Note: datetime is accepted per OGC API Features Core but acts as a no-op for per-dataset feature queries. Per-dataset feature tables contain user-uploaded data with no standard temporal column, so the spec provision “if the collection does not include temporal information, the datetime parameter SHALL be ignored” applies (OGC 17-069r4 §7.15.5).

dataset_id
required
Dataset Id

Query Parameters

Section titled “Query Parameters ”
limit
Limit

Page size for bulk GeoJSON export. The maximum is an admin-configurable ceiling (default 1000; Network settings tab, ogc_items_max_page_size) rather than the 200 used by offset-paged list endpoints, because this route pages via the constant-time after_gid keyset cursor. Per OGC API Features Core /req/core/fc-limit-response-1(C) a value above the ceiling is clamped to it, not rejected.

integer
default: 10 >= 1

offset
Offset
