How do I compensate for a dataset with incomplete or incorrect metadata?
Ferret, the visualization package behind LAS, does its best to make sense of data from the data files provided. Sometimes, however, the associated metadata is incomplete or incorrect as far as Ferret is concerned. The Live Access Server allows you to correct this on the fly without requiring you to recreate the data that you are serving. This is typically done by specifying in the xml configuration file that a particular initialization script other than the default should be used. Several of these initialization scripts are provided in the most recent releases of Ferret or they may be downloaded from the following site:
http://ferret.pmel.noaa.gov/LAS_jnlFiles/
If you have any of the following problems, you can specify the appropriate script in the dataset xml file with:
<properties> <ferret> <init_script>init_...</init_script> </ferret> <properties>
| Climatological axis not understood (out of range error) | init_modulo_t.jnl |
| Depth axis upside down | init_depth_z.jnl |
| Longitude axis not modulo | init_modulo_x.jnl |
| Long load time --regular_t | init_regulart.jnl |
| Setting the bad flag | init_bad_1e35.jnl (one example) |
