I have Data from the Texas rail road commission. I'm trying to get the block data to display with a thick line. The problem is the data is in surveys. I exported a copy of the shapefile. If you take a look at the L2BLOCK colunm you see that I started merging them together, but it take forever if you have to do so for a lot of counties.
I want the blocks to have a thicker line to seperate them from the surveys. Here's what the table above looks like.
You can see that some of them are merged and some not. Is there way to automate merges based on a same block numbers in the attribute table?
