Re: [Geoserver-users] Error: "The specified dimensional parameter is non-positive"

[Julien R. <rob...@og...>]

Well, after a lot of digging today and yesterday, I finally figured out
what probably was the problem. The datatype was float32 and not float64. I
don't really understand why this is a problem, but I've read another issue
<https://gis.stackexchange.com/questions/322703/geoserver-style-for-float32-geotiff-returns-black-image>
online that mentioned float32 could cause some problems while rendering
geotiffs.
Anyway, I've tried using float64 and everything seemed to be working 😅 .
Thanks for the help,
Julien
