comment Exporting polygon shapefile with lat/lon points
The software which reads the input file, how does it know which points belong to one polygon or another? Me thinks if you take the nodes spreadsheet and concatenate the three columns into one line of text for each point, you will have a typical format for these situations. Look up the spreadsheet help for "concatenate" and "working with text". You would save the file type as csv, although between spreadsheet programs there is inconsistency as to how new lines are made etc.

For instance some CAD software will do that as it is imported. What format exactly does your target software need for import?

Opps sorry, I see you want a polygon, not a point feature. Will reconsider.

Obviously you can reverse the y and x. Also, with the text tools, you could parse out the -ve sign etc.

comment how to make decent sense from scattered river depth measurements
@whuber, thanks for helping on this, I limit my comment to the flow of water per se, not topography.

With regard interpolation on a meandering feature, the most practical solution is to increase the number of samples.

comment how to make decent sense from scattered river depth measurements
If you gps is ~3m for horizontal accuracy, the vertical accuracy is probably +- 10 m. What did you want to do with the elevation data? Water typically flows at 1 m fall for every 10 000 m distance. So handheld gps accuracies are not useful for hydrological work.
