One approach is to convert the shapefile to a geodatabase feature class and add a coded value domain to the field. You could then add the value of 2 and 3 and assign descriptions to the values like: 0 - No Cement; 1 - All Cement; 2 - Cement Sides only; 3 - Rip Rap Sides only. However, this results in the classes being in a pretty arbitrary order.
"Your approach depends in part on what you intend to use this information to show in the future"I just need to inform viewers that areas on the L.A river shapefile are either cemented, not cemented, or a mix of both. Is there any way I can do this and only use 1's and 0's?
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 iscemented, 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? Thank you!!!!*This is for ArcMap 10.2
