Concatenating SEG P1 Files

The Import Manager can only convert one SEG P1 file into Shapefile or Open Layers format at a time. To combine multiple SEG P1 files into one file, concatenate them before converting them either using a text editor or from the DOS command line.

To concatenate SEG P1 files from the DOS command line

From the Start menu, select Programs > Accessories > Command Prompt.
Browse to the directory in which the files to concatenate appear.
Do either of the following:

To concatenate a small number of files, at the command prompt, type copy x.seg + y.seg z. where x and y are the names of two existing files to concatenate and z is the name of the new concatenated file to create.
To concatenate numerous files, create an empty file named all.seg in the same directory as the SEG P1 files to concatenate, then at the command prompt, type copy all.seg+*.seg.

If the last record in a SEG P1 file doesn't end with a carriage return and linefeed (CR/LF) the first record in the next file is appended to it without a CR/LF to separate the two and AccuMap considers these two records a single record and you must edit the file with a text editor to manually separate these records with line breaks.
