Writes Digital Chart of the World (DCW) data to a labeled table.
Writes Digital Chart of the World (DCW) data to a labeled table.
- CDPATH(/DG3/WORK/DCW)
- The location of the CD drive. If the DCW is stored on disk, this value should define root directory of the DCW data.
- LIBRARY("NOAMER")
- DCW Library. The DCW library that lines will be extracted from. The DCW is divided into four libraries. Each library exists on a single CD, or in a single directory on disk. These libraries are:
= NOAMER: North America = EURNASIA: Europe and Northern Asia = SOAMAFR: South America and Africa = SASAUS: South Asia and Australia
- OUTLT(DCW)
- Output Labeled Table. The output file, <XXXX>, will contain the coordinates for each point of each line. In addition, three subfiles will be generated:
1) <XXXX>_br - The bounding rectangle subfile contains the upper left and lower right coordinates. 2) <XXXX>_la - The line attribute subfile defines each of the different type of lines defined by the query. The Line attribute description includes: Feature Attribute Index Color Line Style Description 3) <XXXX>_ai - The attribute index subfile contains the attribute index for each line defined by the query.
- LLCOOR
- Lower left coordinate. The minimum lat/lon of the area of interest. Lines which lie East or South of this value will be excluded. These coordinates are the latitude and longitude of the center of the projection that is entered in the same type of units as specified by GEOUNITS.
- URCOOR
- Upper right coordinate. The maximum lat/lon of the area of interest. Lines which lie West or North of this value will be excluded. These coordinates are the latitude and longitude of the center of the projection that is entered in the same type of units as specified by GEOUNITS.
- PO(-- VALID=(1,2,3,4,5,6,7,8,9,10,11,12,13)
- Political Boundaries and Ocean Features. The following fields may be selected for this feature. Selected fields are set to "ON".
International Boundary Dejure International Bound, Defacto International Bound, Dejure & Defacto Administrative Bound, primary Administrative Bound, major Treaty or occupancy Coastal Closure Line Ocean Demarcation Line Ice Line Coastline Ice/Water line Seawall International Date Line
- DN(-- VALID=(1,2,3,4,5,6,7)
- Drainage Feature. The following fields may be selected for this feature. Selected fields are set to "ON".

- RD(-- VALID=(1,2,3)
- Road Feature. The following fields may be selected for this feature. Selected fields are set to "ON".
Dual lane highways Primary or Secondary Roads Tracks, trails, etc.
- RR(-- VALID=(1,2,3)
- Railroad Feature. The following fields may be selected for this feature. Selected fields are set to "ON".

- HY(-- VALID=(1,2,3,4,5)
- Hypsography Feature. The following fields may be selected for this feature. Selected fields are set to "ON".
Close land contour Depression contour Closed land, approx. Carrying Contour Depression, approx.
- HS(-- VALID=(1,2,3,4,5,6,7)
- Hypsography-Supplemental Feature. The following fields may be selected for this feature. Selected fields are set to "ON".

All coastline information about Madagascar will be written to the labeled table files.
All rivers and inland shorelines about Madagascar will be written to the labeled tables.
All rivers, inland shorelines, and roads over the central United States.
After reading and parsing the parameter values, all requested lines which lie within the defined rectangular region are loaded. Once loaded, the output labeled table and all subfiles are opened for writing. The main file contains the points of each line in latitude and longitude coordinates. The bounding rectangle coordinates are written to the "_br" file. Line attribute definitions (e.g. color, description, etc.) are write to the "_la" file. The attribute index of each line is written to the "_ai" file.
An error occurred allocating memory. Rerun the function, and if the error reoccurs, process the image in segments as described by the Description/Algorithm section. If the error again reoccurs, notify the system manager.
Unable to convert entered coordinates to degrees.
A fatal error was encountered during processing. The error message displayed immediately preceding this message is the specific error encountered. Processing is terminated.
