Raster Instance
API endpoint for rasterlayer objects.
Rasterlayers visualise raster data. The actual data is contained in
rastersources. To connect a rasterlayer to a rastersource, configure the
rasterlayer's source
field as follows:
{
"graph": {
"rastersource": [
"lizard_nxt.blocks.LizardRasterSource",
"<uuid of a rastersource object>"
]
},
"name": "rastersource"
}
Note that the organisations of the rastersource and rasterlayer should be
equal. The raster_sources
field cannot be used to configure the source:
it is merely a (read-only) hyperlink to the /rastersources endpoint.
GeoBlocks
Instead of directly visualising a raster source, raster layers can also
perform on-the-fly operations on multiple raster sources. This can be done
by extending the above example for the source
field. See
https://docs.lizard.net. Note that the rasterlayers's organisation must
have geoblocks-permissions to be able to use this feature.
Deletion
If a rasterlayer is deleted, its raster sources (see /rastersources endpoint) will remain available. These need to be cleaned up seperately, or else they will keep using space.
If a rastersource was deleted while there was a rasterlayer referencing it,
the rasterlayer will become broken. In this case, the deleted rastersources
will be listed in the source.deleted_sources
field.
Query parameters:
name
Text filter on the name
field. All text field filter methods,
like startswith
, endswith
, icontains
are supported.
uuid
Filter on uuid
field. UUIDs must be separated by commas and must be
specified in their canonical textual representation (in their
8-4-4-4-12 form, that is). Filtering is case insensitive and may be
done across relationships.
organisation
Filter on Organisations
.
observation_type
Filter on ObservationType
.
layer_collections
Filter on LayerCollection
.
first_value_timestamp
Temporal filter on first_value_timestamp
.
last_value_timestamp
Temporal filter on last_value_timestamp
.
raster_sources__uuid
Show rasters that make use of a raster_source
with given uuid.
access_modifier
Filter on access_modifier
, options are 'Public', 'Private', 'Common', or 'Hidden'.
ordering
Show the results in a specific order.
You can order them by name
, last_modified
, supplier
,
temporal
, access_modifier
, first_value_timestamp
,
last_value_timestamp
, observation_type
, observation_type__code
,
observation_type__parameter
, observation_type__unit
, and
organisation__name
. Add a -
in front to reverse the order.
created:
Temporal filter on created
. Supports various lookup types
(exact
, lt
, lte
, gt
, gte
; created__exact by default).
Filter values should be specified in ISO 8601 YYYY-MM-DDThh:mm:ssZ format.
last_modified:
Temporal filter on last_modified
. Supports various lookup types
(exact
, lt
, lte
, gt
, gte
; last_modified__exact by default).
Filter values should be specified in ISO 8601 YYYY-MM-DDThh:mm:ssZ format.
