Reflecting land-use change

Hi everyone

 

I am working with land-use data in Johannesburg at the moment. I have created maps for each year (1990, 2000 and 2013), but I now need to find a way to create a map showing land-use change between 1990 and 2013. Any ideas?

 

Someone who did the same mapping for a project in Durban categorised the data from 11 classes into three simpler classes (economic, residential and urban) and then clearly joined the data tables. Those maps show land that is in, say, the urban category in 2013, but not in 1990.

 

Firstly, do you have any ideas as to how to best represent land-use change (if not the method I've discussed)?


Secondly, how would you turn the current data set (attirbute table 1 in photos) into the other yes/no by category one (attribute table 2)? What tools, other than a table join presumably, would you need to run?

 

I can't seem to find a topic like this anywhere on here, but if I've missed it, please let me know.

 

Thanks!

 

Alli
