Hi,
I'm not sure if this is the correct list to address this on, but ....
I have lots of files, each with a bunch of lines that start & stop on
each
others ends and I need to convert them into line strings, file by file.
Is there a command-line (batch) way I can do this?
They are currently in DGN (v8) format but I can convert them to SHP,
MID/MIF or
whatever.
What I'm looking to do is to create a batch pipeline that, file by
file, will
take each line, and if either of its ends are within 0.5m of another
line-end,
then join them together to form one line string, then output that
"snapped up"
data to disk. (any format)
Zoltan,
I do not believe you can accomplish this with ogr2ogr. But it is
certainly
possible to write a script, for instance in python, that would accomplish
this in combination with the OGR API. That is the approach I would take.
Hi,
The GMT program 'gmtstitch' will do just that but you will have to
convert the DGN files to gmt with ogr2ogr
