RE: NO_DATA_VALUE in EASI scripts?

Hello Jonas,

With regards to your first question, you can manipulate metadata in EASI using DBReadMetaData() and DBWriteMetadata().Â Some documentation is available here:

Hope this helps,

Subject: NO_DATA_VALUE in EASI scripts?

Hi

1. Can the NO_DATA_VALUE be specified in EASI scripts?
I need to resample data with the option to exclude certain in data values (i.e areas with water etc. as I am resampling NDVI data from 0.07 to 0.5 degrees).

2. Where can I find a full description of the AVERA option in RESAMP (is it a plain average?)

>From the help:
EASI>RESAMPLE="AVERA" | The average interpolation method.
If the resampling has reduced the image by at least a factor of 2, or the function uses NEAR by default.

Regards
