Splitting unwanted parcels off layer.

Question

Hi everyone,

I am new to arc and am in the process of creating a map for our newly constructed bike path. I am using massgis data, and need to remove the unwanted parcels from my map. Is the best way to manually select each unwanted parcel? Or create a new layer from just the parcels I need?

Thanks in advance.

If you want to just remove parcels from display:
Use Identify tool and note IDs or unique numbers of unwanted parcels.
Then in Layer Properties -> Definition query tab: build an expression like:
[OBJECTID] NOT IN (1,2,3,5)

I personally prefer this method, even if I know I'll never need the rest of the data.  It is a good habit to get into when you begin working with larger, more permanent datasets.  It creates less clutter and requires less steps than creating a whole new feature of just the data you want to display.

If you want to permanently remove those parcels, start Edit session (Editor Toolbar: Editor -> Start Editing), select parcel and delete.
You can also create a new layer without unwanted parcels: 
- select those parcels, right click on layer: Selection -> Switch selection (now you have desired parcels)
- then right click on layer again: Data -> Export Data, make sure that Export type is 'Selected Features'
