Notice that the COUNTY field tells you which county uses the particular land use code listed. “HCAD” stands for Harris County. If you scroll down to the bottom of the table, you will notice “FBCAD” and “MCAD” for Fort Bend County and Montgomery County, respectively. The LANDUSE_CODE and LANDUSE_DESCRIPTION fields should look familiar, since they contain the same information as the Land table you looked at previously. The GROUP_CODE and GROUP_DSCR fields store one of ten general land use categories that correspond to each specific land use code. In order to symbolize the parcels using these generalized land use categories, you will also need to join the lookup table to the land use table and the parcels feature class. You will perform the join using the land use code field that is common to both your land use table and your lookup table.

Joining Tabular Data
Now that you have examined all of the data tables, you are ready to join them all together. It is possible to join tables together in any order, but you will want to join both land use tables to the back of your DowntownParcels attribute table, so that you can later symbolize the parcels based on their land use. You will first join the Land table to the DowntownParcels feature class using the unique HCAD account number as the common join field.
