Whoever knows how to do this would be saving my life. For those of you who know about the L.A river, almost 80% of it is
cemented, while certain areas are being rehabilitated and cement is being removed. I have a shapefile of the Los Angeles River andcreated a new field called "Cement" in the attributes table. I selected the
areas with cement and gave them a "1" in the attributes table while areas without cement are "0's". The problem I have is figuring out how to select areas on the river shapefile that have cement on the
sides and no cement in the middle. Also, there are areas with grouted rip rap lining the sides of the river while having no cement in the middle. Does anyone know the best way to do this?
