Importing Text file for Lines

[rayngwt]

Hi,

Hoping somebody can help me.
I have a txt file in this structure, with thousands of entries records.

F1,lat1,lon1,lat2,lon2,attrib1,attrib2,attrib3...
D5,-35,135,-45,145,345,102,line4
D5,-45,145,-30,132,665,203,line56

I need to import them but I need each record line to be an individual feature-line, meaning each feature has only 2 vertices. How can I do this using the import ascii function? ... as it keep tesellating the records together which is not what I want.

Thanks a million, Raymond

Raymond,

Unfortunately there is not currently a way to load generic text files with anything more than one coordinate pair per line unless your ascii text file uses the WKT (well-known-text) format. You will only be able to get one pair of coordinates from each as it is now.

Hi Mike,

Thanks for the reply. Yeah, there's only one par of co-ords each line, the rest are attributes, so the example i gave might be confusing.

Its something like that ...
ABC,lat1,lon1,lat2,lon2,Name,label1,etc..
The problem I have is that the pair of vertices connect to records below the first record.

Is this possible?

Thanks, Raymond

Raymond,

When I say a 'pair' of coordinates, I meant one X and one Y. Your lines have 2 pairs of coordinates per line making a line segment, which is what is not supported. You could import the data as 'Point Only' and get one of the pairs of coordinates from your text file for a point feature, but you can't get both.

Let me know if I can be of further assistance.

Thanks,

Hi Mike,

Thanks for clearing that up. I will try to imagine some other way.

Thanks, Raymond

I have the exact same situation--I want a vector file with thousands of separate line segments, and I've got start and end coordinates for each segment.

Could I treat them as polygons--e.g., draw each segment from start to end, then back to start?
Lat1,Lon1
Lat2,Lon2
Lat1,Lon1

Then throw in the other attributes, put a blank line in the script, and move on to the next line segment?

If GM can't handle this, does anyone know what I could do?

Thanks

So long as you just have one coordinate on each line you should be able to easily load that file using the File->Open Generic ASCII Data File menu command. See http://globalmapper.com/helpv11/Gene...structions.doc for details on the accepted ASCII formats.

Let me know if I can be of further assistance.

Hi there,

just an idea. It may be possible to rearrange the two coordinate pairs that define the line into something like the ArcInfo generate format, see link here http://intevation.de/~jan/gen2shp/gen2shp.html, bottom of page and then open into GM as a generic ascii file. Attributes won't come in though, so possible to export as a shape file and append attributes in the dbf file. In other situations I have used ArcInfo generate format and it has worked well.
