shrug-l: Calculate Geometry->Length Disabled

[Tripp Corbin]

Bill,

Wow sounds like fun. The first things that come to mind to check are:

1.      Does your line feature class have a coordinate system assigned?

2.      If it does have a projection assigned is it in a Geographic or Projected? If Geographic try projecting to Projected

3.      Are you in an edit session or not? If not try running in an edit session.

4.      If you are using ArcGIS 10, is the field marked as read only?

5.      Is it in SDE and if so do you have permissions to right to that field?

6.      If the line is a Geodatabase feature class try converting to Shapefile or visa versus

7.      Have you tried using the field calculator and building an expression to calculate a distance?

 

Just a few ideas off the top of my head.

Subject: shrug-l: Calculat Geometry->Length Disabled

 

Shruggers,

 

Trying to calculate length in ArcGIS 10, Service Pack 3 on Windows 7.

Used Calculate Geometry sucessfully to calculate the XY end coordinates of the lines in a 400, 000+ record dbase file.

Then used the tool 'XY to Line' to produce a resultant file.

Added a field called Distance (data type double) to the result file.

Right click on 'Distance', scrolled to Calculate Geometry.

The top dropdown box showed Length-Disabled.

This procedure worked for a file with 4 records.

Here is the procedure: http://kb.mit.edu/confluence/pages/viewpage.action?pageId=11338190

Had some problems until I got a Unique ID for all the records but after that still got Length -Disabled.

 

Any help will be sincerely appreciated!

Please respond to: Bill.Alfred at med.fsu.edu.

 

Happy New Year,

Bill Alfred, MS, GISP
