+3Hello!
I need to get the properties of a big GeoTiff ( 146299 cols x 213475 rows or even bigger)
Among these properties I need to extract the ref system, the resolution, splot the bands etc. Apparently, in order to get them FME needs to read all the raster and this process takes forever.
Is there any alternative way to get these without reading all the raster?
Thanks
Oskar
Have you tried to turn off "Feature Caching" and "Feature Counting" option? It can speed up the processing.
What's more, you can use FeatureReader and option in GeoTIFF called: "Pyramid Level to Read" - "When a GeoTIFF file contains pyramids (reduced-resolution images), this parameter specifies the pyramid level to read. Pyramid level 0 represents the original raster data. Values greater than 0 represent a reduced-resolution image."
+3Thanks so much skime
I checked with the pyramid level parameter and it works!
IN the first place I thought 0 value was the lowest resolution. I mean, the other way round.
My problem is that I won't know the lowest resolution level beforehand and I may have raster with no pyramid overlays either. I also set a big number in the pyramid level (let's say 100) and I reads the max resolution....
Thanks again anyway
