This directory contains the "gis2dx" filter, which reads many types of GIS data, including DEM, DLG, ERDAS, MODFLOW, ARC Shape files, and native ARC files. It also contains the DXF format converter. For more detail on the specific types of DXF format data which are supported see the "DXFinfo.txt" file in this directory.
General Information:
To run the program as a stand-alone converter, type: gis2dx
To run the program as a filter from DX:
1) in the Import module set the "filename" to be: "!gis2dx -filter -p"
2) set the "filetype" to be "dx".
If you have ARC/Info data:
If you are running on an IBM RS/6000, both programs which are required to read arc data are available. You will need both "gis2dx" and "arcrpc_svc". If you get an error saying "rshd: permission denied", try starting "arcrpc_svc" by hand first, and then starting "gis2dx" and seeing if it can connect that way.
If you are running on any other architecture, you have two options:
1) convert your data to an ARC Shape file first. Use the "a2shape" program provided by ESRI, or use "arcview" and save the file in "shape" format.
2) if you have the SDL development libraries, compile the "arcrpc_svc" program yourself. The source files are in the d.arc subdirectory, and there are Makefile.$ARCH files for each architecture.
If you start the converter and you have a valid ARC license but the ARC choice is still greyed out, get out and set $ARCHOME first to point to the ARC home directory. Then when you start "gis2dx" it should enable the ARC part of the converter.
DEM -- Government distribution Digital Elevation Model files:
ASCII format files are supported.
DLG -- Government distribution Digital Line Graphs.
ASCII files in the optional DLG format are supported.
ERDAS LAN files:
Binary format files are supported.
ERDAS Imagine files:
Compressed format is not supported yet. Unsigned char data is the only supported pixel format which has been tested. For multi-layer image, each layer must be imported separately and recombined inside DX.
Modflow -- Modflow heads/drawdowns output files.
Binary format files are supported.
