Issues with Dissolve

Discussion created by drbarlow on Mar 24, 2011
Hello,

I am trying to dissolve a polygon shapefile containing roughly 17,000 records. These polygons represent aerial photos as have a field named "Year_" which I am using to as the dissolve field. There are 10 different years that are in the polygons, there for it should make a shapefile with 10 polygons, one for each year. However, it only dissolves about 2000 of the records, all with early years in range. I have a similar shapefile with even more records and the dissolve works perfectly on that one. Any feedback is greatly appreciated!
