GetMap — Symbol style

wms_getmap_symbol_style

Input: test/input/wms_getmap_symbol_style.get

GET /wms?...&layers=test:precipitation&styles=precipitation_red_rain_style

GetMap — Error handling

When a request contains invalid parameters the server returns either an XML service exception (default) or an in-image error (when EXCEPTIONS=INIMAGE or format-specific variants are used).

Test	Error	Response format
wms_getmap_invalid_crs	Unknown CRS	XML exception
wms_getmap_invalid_crs_json	Unknown CRS	JSON exception
wms_getmap_invalid_layer	Unknown layer	XML exception
wms_getmap_invalid_layer_json	Unknown layer	JSON exception
wms_getmap_invalid_style	Unknown style	XML exception
wms_getmap_invalid_style_json	Unknown style	JSON exception
wms_getmap_invalid_time	Invalid time	XML exception
wms_getmap_invalid_time_json	Invalid time	JSON exception
wms_getmap_invalid_version	Unsupported version	XML exception
wms_getmap_invalid_version_json	Unsupported version	JSON exception
wms_getmap_invalid_format	Unsupported format	XML exception
wms_getmap_invalid_layer_inimage_pdf	Unknown layer	Error PDF
wms_getmap_invalid_time_inimage_pdf	Invalid time	Error PDF

In-image error renderings (EXCEPTIONS=INIMAGE) carry the failure message inside the requested image format:

Test	Output
wms_getmap_invalid_crs_inimage_blank — blank PNG
wms_getmap_invalid_crs_inimage_png — error PNG
wms_getmap_invalid_style_inimage_png — error PNG
wms_getmap_invalid_format_inimage_svg — error SVG
wms_getmap_invalid_version_inimage_svg — error SVG

GetMap — Grid Engine layers

The grid: layer namespace is served by the SmartMet grid-content engine (Redis-backed GRIB1/GRIB2/NetCDF) rather than the QueryData engine. Tests are named wms::grid::<layer>::<producer> (and wms::qd::... for the analogous QueryData wind-stream cases) — the :: segments survive intentionally in the filename so the test harness can derive the layer / producer pair from the path.

All requests use format=image/svg+xml; the PNG previews here are rasterised from the SVG outputs. Producers exercised by the suite:

• pal — Finland-area model (default bbox `59,17,71,34$, 300 \times 500 \text{px})
• $ecmwf_eurooppa_pinta` — ECMWF Europe surface (bbox `34,-12,74,40$, 500 \times 500 \text{px}) \text{selected} \text{with} $&producer=ecmwf_eurooppa_pinta`
• ecmwf_maailma_pinta — ECMWF global surface, world bbox

Product configurations live in test/wms/customers/grid/products/.

Temperature

Six temperature layers with progressively richer styling — base isobands, isolines, smoothing, labels, multi-style composite.

Test	Producer	Output
wms::grid::temperature_1::pal	pal
wms::grid::temperature_1::ecmwf_eurooppa_pinta	ECMWF Europe
wms::grid::temperature_1::ecmwf_eurooppa_pinta::time_interpolation	ECMWF Europe, interpolated time
wms::grid::temperature_1::ecmwf_maailma_pinta	ECMWF World
wms::grid::temperature_2::pal	pal
wms::grid::temperature_3::pal	pal
wms::grid::temperature_4::pal	pal
wms::grid::temperature_4::pal::time_interpolation	pal, interpolated time
wms::grid::temperature_5::pal	pal
wms::grid::temperature_6::pal	pal

The ::time_interpolation suffix tests requesting a timestamp between two stored timesteps; the grid engine interpolates linearly. TopoJSON output of the same isobands is exercised by wms::grid::temperature_1::pal::topojson and wms::grid::temperature_2::pal::topojson (JSON output, not shown here).

Precipitation

Test	Producer	Output
wms::grid::precipitation_1::pal	pal
wms::grid::precipitation_1::ecmwf_eurooppa_pinta	ECMWF Europe

Raster

The raster_* products render gridded data through a RasterLayer that emits PNG-in-SVG <image> elements. _t1 / _t2 suffixes select between alternative styling templates.

Test	Producer	Output
wms::grid::raster_1_t1::pal	pal
wms::grid::raster_1_t1::ecmwf_eurooppa_pinta	ECMWF Europe
wms::grid::raster_1_t2::pal	pal
wms::grid::raster_1_t2::ecmwf_eurooppa_pinta	ECMWF Europe
wms::grid::raster_2::ecmwf_eurooppa_pinta	ECMWF Europe
wms::grid::raster_3_t1::pal	pal
wms::grid::raster_3_t1::ecmwf_eurooppa_pinta	ECMWF Europe
wms::grid::raster_3_t2::pal	pal
wms::grid::raster_3_t2::ecmwf_eurooppa_pinta	ECMWF Europe
wms::grid::raster_4_t1::ecmwf_eurooppa_pinta	ECMWF Europe
wms::grid::raster_5_t1::ecmwf_eurooppa_pinta	ECMWF Europe
wms::grid::raster_6_t1::ecmwf_eurooppa_pinta	ECMWF Europe

Wind direction / speed

Vector quantities decomposed into separate direction and speed layers, plus a combined-style layer.

Test	Producer	Output
wms::grid::wind_direction_1::pal	pal
wms::grid::wind_direction_1::ecmwf_eurooppa_pinta	ECMWF Europe
wms::grid::wind_speed_1::pal	pal
wms::grid::wind_speed_1::ecmwf_eurooppa_pinta	ECMWF Europe
wms::grid::wind_speed_2::pal	pal
wms::grid::wind_speed_2::ecmwf_eurooppa_pinta	ECMWF Europe
wms::grid::wind_speed_and_direction_1::pal	pal
wms::grid::wind_speed_and_direction_1::ecmwf_eurooppa_pinta	ECMWF Europe

wms::grid::wind_speed_1::ecmwf_eurooppa_pinta::topojson exercises the same layer with TopoJSON output (not shown).

Wind streamlines

Streamline traces driven by U/V wind components, served from both grid and QueryData engines for parity testing.

Test	Engine / Producer	Output
wms::grid::wind_stream_1::pal	grid / pal
wms::grid::wind_stream_1::ecmwf_eurooppa_pinta	grid / ECMWF Europe
wms::grid::wind_stream_4::ecmwf_eurooppa_pinta	grid / ECMWF Europe
wms::qd::wind_stream_2::ecmwf_maailma_pinta	QueryData / ECMWF World
wms::qd::wind_stream_3::pal	QueryData / pal
wms::qd::wind_stream_3::ecmwf_maailma_pinta	QueryData / ECMWF World
wms::qd::wind_stream_4::ecmwf_maailma_pinta	QueryData / ECMWF World

wmsmap — Plain background map

wmsmap (under the ely customer) is the simple Natural-Earth + graticule background that the WMS GetCapabilities tests use for projection coverage.

(Same image as wms_getmap_png above — wmsmap is the underlying product name.)
