How To: Define a .DES INFO file for ARCDFAD input coverages
A description of the .DES INFO file and its item definitions for ARCDFAD conversion.
The .DES file must contain the following items:
ITEM NAME WIDTH OUTPUT TYPE ----------------------------------- IDENTIFIER 20 20 C VALUE 30 30 C
The item values for each of these items are specific for DFAD data. The IDENTIFIER field will contain certain item values. The VALUE field may or may not be populated for a given record. Here is an example .DES file:
An Appropriate values for the remaining items must be determined from the DFAD format specifications. See Related Information to find out how to obtain those specifications.
You could use AML to automate the creation of the .DES file.
/* NAME: DES.AML /* /* USAGE: &RUN DES.AML /* /* NOTES: /* /* The output value for the VALUE item of the .DES must be /* edited to contain the correct values for the user's input /* data area. /* /* Run this AML from the Arc prompt. /* Run this AML from a directory that is NOT the workspace /* directory that will be converted with ARCDFAD /* /* This is not an ESRI supported AML. Please use at your own risk. /* Also, please make a backup of your data before running this AML /* and carefully check the output. This is just a skeleton AML with /* no real error checking. It is meant only as a guide to developing an /* AML specific to your data inputs and desired outputs.
