Hello!

I'm trying to get/return XY coordinates of all nodes within a feature (polyline or polygon).

I'm using ArcView and know that in ArcInfo there is Feature Vertices to Points tool in Data Management toolbox.


I've tried with ET tools but I didn't come to a result.

Please suggest a different solution, preferable open-source or free tool.

Thanks in advance!

Hi Adrian

ET GeoTools has always worked for me.
Maybe choose the "vertices" option rather than nodes. And it adds the coordinates in separate columns.

Might also give trouble if your data has no projection information...

Kind Regards

Hi!

Thanks!
I'll try with that tool also.

You can view all the coordinates when you open the table of the editing sketch. But so far I haven't been able to extract those coordinates. Things like Copy-Paste haven't worked for me... So I'd be interested, too, in a fast and simple solution.

Cheers,
Kathi

FME's CoordinateConcatenator can do it as well.

You can convert to MapInfo file format. There are two files in MapInfo format; both are plain text.
Use ogr2ogr (part of the FWTools distribution fwtools.maptools.org) to convert from shapefile to mapinfo.

In a DOS command window the command below, converts the shapefile to mapinfo format.

>ogr2ogr -f "MapInfo File" lines.mif lines.shp

This creates a .mif and a .mid file. The coordinates are in the .mif. Add .txt to the file name and open with notepad or word. At the top is information about the coordinate system and projection. Coordinates are listed as x y for each vertex. Attributes for each element are in the .mid.

There are others tools and software that can be used. Global Mapper and Manifold GIS can export to 'well known text' WKT or Polish map format. The is a perl module for reading shapefiles. 'Ungenerate' can also be used to create a generate file format that is plain text.


Best,
Dan

You could try this: It's also in the Arc Desktop help.
