Pixel Geo-Coding
The Pixel Geo-Coding can be used if the user has two bands
filled with accurate latitude and longitude values for each pixel.
For example the FSG and FRG products have corrected latitude
("corr_lat") and longitude ("corr_lon") bands. These bands can be
used to replace the current geo-coding associated with the
product.
NOTE:
For information on how to enable the pixel geo-coding on import
for MERIS FRG/FSG data products, please see the Envisat help page.
Attach Pixel Geo-Coding
- Longitude Band
The band which keeps the longitude values for each pixel.
- Latitude Band
The band which keeps the latitude values for each pixel.
- Valid Mask
This mask is used by the search algorithm when trying to find the
pixel position to a given lat/lon. Only pixels which meet the
expression are included in the search.
- Search Radius
This value is used by the search algorithm when trying to find the
pixel position to a given lat/lon. A higher value means that the
area to search for the proper pixel position is greater and the
risk not to find the searched value is smaller. The greater the
value is the longer takes the search.
Detach Pixel Geo-Coding
Just detaches the current pixel geo-coding and restores the
previous geo-coding.
