FIS service bad response | Planet Community

Hello!

I’m trying to do this petition to FIS service

http://services.sentinel-hub.com/ogc/fis/{instance_id}?LAYER=NDVI-INDEX&STYLE=INDEX&CRS=EPSG:4326&TIME=2020-04-01/2020-04-18&RESOLUTION=10&MAXCC=100&GEOMETRY=POLYGON((42.08985696040646 -1.076664062254 , 42.08908020529746 -1.076030704588746 , 42.08944872211567 -1.073486196228113 , 42.08827842977837 -1.067977433723025 , 42.09647823645694 -1.066892191071831 , 42.09667570560195 -1.06748714203039 , 42.09678264608 -1.068433426143738 , 42.09721723447621 -1.069271630069536 , 42.09736809923614 -1.069834689799757 , 42.09708490300881 -1.070980844635927 , 42.09678137221947 -1.0726909840333 , 42.09679173725243 -1.07335079565359 , 42.09645077809419 -1.074021116224241 , 42.09237247150098 -1.073361809357199 , 42.08985696040646 -1.076664062254))

And i get this response:

Min and max are same values and obviusly stDev is 0.

I think the problem can be POLYGON and his coordinates, i tested reverse coordinates but have the same response .

Thanks!

By default the RESOLUTION parameter is in same coordinates as the CRS of the polygon. In your case this is in EPSG:4326, so you define resolution as 10 degrees… Therefore you only have one pixel.

The appropriate way would be to recalculate 10m into EPSG:4326. There is also a workaround, to state RESOLUTION=10m, in which case we will do an approximate transform in the appropriate CRS.

Hi Grega,

Thanks for your reply.

I focus to RESOLUTION parameter and i add “m”, “RESOLUTION=10m” and it seems to be working.
