Dissolving parcels to each block with the same landuse

AlmazNaizghi — Wed, 25 Feb 2015 21:56:09 GMT

Hello,
I have a city wide data of parcels with different land use. I want to dissolve each parcels based on their land use at each block.

1, Image one below is the example of my original data.

2. Image two below with two blocks I manually dissolved (RL) as example is what I want my data to look for the whole city. But I do no how to do it?

Thanks,

Almaz

You mention dissolving, so I assume you've tried the Dissolve tool. Have you?

Thanks Darren,

Yea I tried dissolve....but what it does is dissolve the whole city data based on the different land use. For example it dissolve all "RL" together. However, I want my data to look like the example I did in image two. I mean "RL" for each block.

Thanks,

Once you dissolve based on land use, you can split apart the separate blocks using Multipart to Singlepart, or select all, then Explode. Either method will separate disjoint polygons.

Great idea!

I never thought about using Multipart to Singlepart to separate the blocks after they are dissolved. I will try and see how it works.

Thanks again.
