petascope - FIX - WMS allows to add request subset inside coverage expression in WCPS query fragment

[Bang Pham Huu]

For example, this request:

rasdaman/ows?service=WMS&version=1.3.0&request=GetMap&layers=cb_global_development_stage&bbox=29.98,-10,60,20.02
&time="2022-08-09T08:53:00.000Z"&width=800&height=600&crs=EPSG:4326&format=image/png&transparent=true&styles=overlay_3_and_7

Here, the value from time parameter: "2022-08-09T08:53:00.000Z" will need to be added inside subset expression $c[ ... ].

with style overlay_3_and_7 is WCPS fragment with:

(
switch

case $c[development_stage(7)] = 7 return {red: 255; green: 0; blue: 0; alpha: 155}

default return {red: 0; green: 0; blue: 0; alpha: 0}
)


overlay


(
switch

case $c[development_stage(3)] = 3 return {red: 0; green: 255; blue: 0; alpha: 255}

default return {red: 0; green: 0; blue: 0; alpha: 0}
)
