How is this done in GIS? Report this article as Inappropriate to us !!!Login to Reply

I know almost nothing about GIS, but it occurred to me that the capability I'm looking for might be a GIS feature, so here goes:

If one wants to assign a bounded item (polygon) to a database field, how would that be done.

Is this only a manual process, or are there automated ways of identifying polygons and then assigning identities to each one to enable linking to a database fileld?

What are the requirements for the graphic being used as the source? Does it have to be a certain type of file?

What tools or software would be used to do such a task?

Thank you for entertaining my attempts to learn.

The polygon's attribute table will have to have a field in it that is the same as one in the other database, known as a key field. Each record in this field should be unique from all the others. Once you have your polygons digitized and have a key field for the attribute table and database you can join the two together. It is a very simple function in Arcmap 8.3. The database table will have to be in DBASE-IV format to be used in ArcMap.

If you don't have a common field, you might be able to construct one by putting the labels to another cover....
by default Arc/Info will number the labels from north to south...so you might be able to figure out which poly is which....maybe not if your map is complicated....
