There is a better tool for this in the Spatial Statistics Tools. It doesn't include any fields you do not want. Export Feature Attribute to ASCII Thanks for the reply. How would this work though using a table as an input rather than a feature layer? ... View more

Unfortunately they are scale independent. ... View more

A possible way around it is to create a new feature layer where you join the attribute table of your layer to the hyperlinks table, in essence creating new features for each hyperlink record. Some features will overlap since you have many hyperlinks per feature. You could then make your new hyperlink layer features transparent in your map. When a user uses the hyperlinks tool they will only see the blue feature layers, which when selected will give you a list of which hyperlinks at that particular location. Hopefully you get the gist. ... View more

You can use Feature To Polygon tool to convert the ellipse lines to polygons, if they don't overlap. Thank you for the suggestion, however this tool is only available to ArcInfo license users. I have an ArcView license unfortunately. Any further suggestions would be welcome. ... View more

The following VB script is from http://forums.esri.com/Thread.asp?c=93&f=987&t=106536 I tested it with a mxd containing a point file and a line file, the point file being first in the TOC. Do not run it in Edit mode. It works as long as the points are not at the beginning or end of the line as this results in lines of zero length.

While I have not had an opportunity to try it out yet, I should probably clarify as maybe it wasn't quite clear in my problem definition, that I only have a list of station names, not their actual coordinates. The only stations that I do have coordinates for are the ones at the start and end of the line. Based on this, I would like to position the other stations along this line as point features. ...

Thank you for your reply Eric. Since I use ArcGIS 9 (not 10), I took the "Introduction to ArcGIS 9 Geostatistical Analyst" free virtual campus course (http://training.esri.com/acb2000/showdetl.cfm?DID=6&Product_ID=808). How does the course you suggested (albeit for a version I do not have) compare? In your previous message you said that the semivariogram cloud in my pdf didn't appear to show much spatial autocorrelation. How did you arrive at this conclusion? What would the cloud look like if there was spatial autocorrelation? Would there be spatial autocorrelation if for instance most of the data values lay along the bottom x-axis (around y = 0), while at the same time, a number of values hovered along the top of the graph. Thanks again for your thoughts and patience. ... View more
