Thank you.
Question
merging areas by a common attribute
I have several areas that have common boundaries and a common attribute. I would like to dissolve the lines that touch to make one larger area. I tried the amalgamator, but that didn't work, I have also tried the aggregator, but that isn't working either. The data is an access workspace for a geomedia layer. Any suggestions would be helpful.
Hi Joan,
Takashi is spot on, the Dissolver will do the trick. Specify the common attribute in the Group By to only dissolve those with a common value.
If the areas aren't perfectly aligned, consider inserting a Snapper (or similar) before the Dissolver.

I tried the Dissolver, but my data is in an access table from Geomedia, should I export it as a shape file or something else so the dissolver will recognize it as geometry?
Thank you.
Which reader are you trying to read the geomedia data with? I think you can read geometries normally with the FM0 (Intergraph GeoMedia Access Warehouse) Reader...
