I guess the question is... is it necessary to upgrade to an even higher precision?  If the coordinates don't move, even if upgrading to a higher resolution, then there should be nothing to worry about right? The sole reason I am asking is because I have a good quality, trusted dataset which has my desired spatial resolution which I am trying to match - for the sake of consistency! I am unsure how to change the spatial resolution within an existing feature class or XML file so I can match my desired values. ... View more

So just to clarify what I mean, If I have an XML schema, and when I import it into a geodatabase it creates a feature class with the following resolutions: XY Resolution of 0.000000001 Degree (9 decimal places) XY Tolerance of 0.000000008 Degree (9 decimal places) But my desired resolution is: XY Resolution of 0.000000000005 Degree (12 decimal places) XY Tolerance of 0.00000000001 Degree (11 decimal places) How can I specify the spatial resolution and tolerance of my imported feature class? ...

Brilliant idea, you beat me to it. ... View more

I was curious on this myself, and have done some research. Apparently some people have made use of the 'Collapse dual lines to centreline' tool in ArcInfo.  However through experimenting with this, I've had some problems generating anything that looks remotely like a centreline! The only other option I can think of is to draw lines across the peninsula, joining points, and then draw a line, snapping to the midpoint of each of those lines.  Having said that, this would not be practical for a peninsula containing several vertices... I don't know how else to approach this, and would be interested to find out a solution on this.  Surely it's a relatively simple function which does not require scripting...

Info on converting Lyr to SHP: http://forums.esri.com/Thread.asp?c=93&f=1149&t=296657 There is also a 'Raster to Point' geoprocessing tool available in ArcMap.  Try reading up about the tool so you have a better understanding of how it works. http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//001200000007000000.htm ...

The intersect tool should do this for you. Or else, if you go to the Selection Menu and choose 'Select by Location' you should be able to use the 'intersect' spatial selection option to intersect between the two layers. Hope this helps! ... View more

Thanks Melita.  I'm unsure on the ease of creating a tool that does this, however if anybody else would find a geodesic buffer tool useful for generation from polygons or lines, then you can support the idea here: http://ideas.arcgis.com/apex/ideaSearchResults?s=geodesic+buffer ... View more
