Corridor Query (Large Area Buffer)

The Large Area Buffer feature in LightBox Vision™ allows users to quickly and easily capture all of the parcels that will be impacted by a project that will take place around a large subject area, such as a right of way. Capture up to 50,000 property owners to conduct notifications for major infrastructure projects spanning up to 100 miles.

Execute a Large Area Bufer

1. Click directly on your subject feature while it's displayed on the map (ex: a Pipeline layer) to open the editing toolbar. Then select View Info from the toolbar to open its Location Information Panel.

2. From the Location Information panel, click on the Large Area Buffer command. 

3.  Enter in your desired buffer distance in the Large Area Buffer window (Max distance = 5,280'). Click Create List to generate a list of up to 50,000 parcel records (however only 2k records can be exported unless your account has a data license for more extractions).

• Options:
  • Show Buffer: Displays the buffer on the map prior to creating the list of parcel records.
  • Clear Buffer: Clears the display of the buffer prior to creating list.

4. A notification window will appear in the top right corner. You will see the processing statuses as a message. When the process finishes, click on the green check mark icon.

5. The Large Area Buffer results window will display the number of results found. Click Add to List if you'd like to add them to the results list.

6. To view the current or last buffer on the map, open the Layers Menu from the Main Toolbar and turn on the Buffer layer.

Frequently Asked Questions

Q: Where can I run a Large Area Buffer from?

A: You can run a Large Area Buffer from any geographic layer including a loaded geospatial layer such as a planned utility line or from layers created in LightBox Vision™ such as a Markup.

Q: What is the maximum line distance that I can run a buffer from?

A: The maximum line distance you can run a Large Area Buffer from is 100 miles. There is also a maximum number of parcel records that will be returned in a single Large Area Buffer. If this maximum number is reached then you will need to break your buffer into smaller segments.

Q: What is the maximum allowable buffer distance?

A: The maximum buffer distance for a geographic feature is 5,280', or 1 mile. If you enter a buffer distance greater than 5,280' then you will be notified to change your distance to an allowable range.

Q: What is the maximum number of parcel records retrieved in a single buffer?

A: The maximum number of parcel records retrieved in a single buffer is 50,000. If your buffer area intersects more than 50,000 parcel records, then you will be notified that your buffer exceeds the max records. You will still be able to generate a list from the 50,000 records picked up in the buffer but there will be a gap in the total number of records intersected by the buffer and the number in the list. To reconcile this gap you will need to break your buffer into smaller segments.

Q: Can I export the results of a Corridor Query?

A: The resulting parcel records from a Corridor Query can be exported using two methods:

• Export for Mail Merge: Maximum allowable records (50,000)
• Export to CSV: Top 2,000 records (same as the standard LightBox Vision™ Property Search)
