Hi, I have problem transposing my database table which is to be merged / joined with the shapefile file (*.dbf) inorder to have one-to-one relationship with shapefile polygon. As we know that inorder for the polygon to be rendered in GIS, it has to have one-to-ope relationship.
One to many table: Poly_ID Period Age 01 1 32 01 2 34 02 1 30 03 2 21 One to one table Poly_ID Period1 Period2 Period3 01 32 34 02 30 03 21 04 35 Now, is it possible to use one-to-many table for mapping using spplot / plot? The result data I am trying to map using spplot has 1 to 70 years periods. I want to produce maps per period, for 10 years or more for forest management regimes in forest stand. Any alternative? Thanks in advance. Noli _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo
