The suffixes shown are prefixed by the current <WriterKeyword> in a mapping file. By default, the <WriterKeyword> for the DTED writer is DTED.
DATASET
Required/Optional: Required
The name of a folder into which the DTED files should be written. See DIR_STRUCTURE for more details on folder and file naming.
Example:
DTED_DATASET D:\OUTPUT\DTED
Workbench Parameter: Destination DTED (Digital Terrain Data) Folder
LEVEL
Required/Optional: Optional
The product level to use. Near the Equator, products have the following resolutions for a one-degree square cell:
- Level 0: 121x121 (30 arc second postings)
- Level 1: 1201x1201 (3 arc second postings)
- Level 2: 3601x3601 (1 arc second postings)
- Auto: If the source format is DTED, “Auto” will use the resolution level of the source data. If the source format is not DTED, “Auto” sets the default resolution to “1” .
The resolution in latitude is reduced for cells near the North and South Poles.
Range: 0 | 1 | 2 | Auto
Default: Auto
Example:
DTED_LEVEL 0
Workbench Parameter: Resolution Level
DIR_STRUCTURE
Required/Optional: Optional
If set to YES, this keyword will create subfolder structure with tiles stored in subfolders by longitude with files named by latitude. If set to NO, this keyword will create files with no subfolder naming structure.
For example, if the output is specified by data written to the 1 degree square at 80 degrees west, and 43 degrees north, with the option set to NO and DATASET is C:\Output\Data, the output would be a file written out to C:\Output\Data\w080n043.dt1. If the option is set to YES, the output would be written out to C:\Output\Data\w80\n43.dt1. By default, the value is set to YES, as this is the convention according to the specification.
Default: YES
Example:
DTED_DIR_STRUCTURE YES
Workbench Parameter:Create subfolders
VERTACCURACY
Required/Optional: Optional
This keyword may be used to set the absolute vertical accuracy (User Header Label [UHL] record, characters 29 to 33) with 90% assurance that the linear errors will not exceed this value relative to mean sea level. Valid values are integral numbers in the range 0000-9999 with leading zeros. By default, the value NA is used indicating the vertical accuracy information is not available.
Default: NA (not available)
Example:
DTED_VERTACCURACY 0200
Workbench Parameter: Vertical Accuracy
SECURITYCODE
Required/Optional: Optional
This keyword may be used to set the security classification code field in the Data Set Identification (DSI) record (character 4). The default value is U (Unclassified) but any of the following values may be used:
- T – Top Secret
- S – Secret
- C – Confidential
- U – Unclassified
- R – Restricted
Default: U (unclassified)
Example:
DTED_SECURITYCODE R
Workbench Parameter: Level
PRODUCER
Required/Optional: Optional
This keyword may be used to set the producer agency code (DSI record, characters 103 to 110) for the generated cells. The first two characters should be the DIA country code followed by additional code information provided by the national defense mapping agency.
Default: blank
Example:
DTED_PRODUCER US090078
Workbench Parameter: Producing Agency
COMPILATION_DATE
Required/Optional: Optional
This keyword may be used to set the compilation date (DSI record, characters 160 to 163). This date should be the most descriptive date in YYMM format. Defaults to blank, indicating it is unknown.
Example:
DTED_COMPILATION_DATE 9609
Workbench Parameter: Production Date
