Segmentation Violation Error

Discussion created by mattpis on Sep 28, 2010
I am currently attempting to create a contour map from elevation data.  The shapefile with the elevation points are clustered in a study area, but there are two outlying points that were used as backsites from the survey.  I created a polygon to serve as a SiteOutline and attempted to Convert to Grid in order to establish an Analysis mask for the contour line creation in Spatial Analyst.  Unfortunately, I received an "Error: Segmentation Violation" message.  Is this because of the outlying points since I did not, nor do I want to, include them in the SiteOutline shapefile?  Should I go back to the original data and eliminate these points from the shapefile?  Thanks!
