While using GIS, you may encounter a need to retrieve data for features within a proximity to another feature. This tutorial will walk you through how use a buffer to export data for parcels along a stretch of road. The steps in this tutorial can be modified to better suit any use-case you might have.
Step 1 – Zoom in on the area you want to retrieve feature data.
Step 2 – Determine how you want to buffer (e.g. by parcel, by line, by multiple parcel, etc. )
- For this example I will use a line and select parcels along a street.
Step 3 – Select an shape option from the “Location Information” section of the “Getting Around” tab .
Step 4 – Select “Buffer Shape” to the right of the identify tools. Select the “Results for” list and click “Select None”, then check the Parcels textbox to identify only tax parcels.
Step 5 – Trace the centerline of the street you want to create buffer for using the Line tool, and double click to end tracing. This will bring up the buffer prompt.
Step 6 – Select a distance from the line to buffer. In this case we will use a 50 foot buffer.
- Add Buffer to Markup will add the buffer as a visible shape drawing on the map.
- Preview will show what area the buffer will select so you can use “trial and error” to get the right buffer area before clicking OK.
- The units default to feet, but there are other options to select if appropriate.
Step 7 – When completed, select OK to accept the buffer identify. The parcels identified will show in the Results Pane on the left of the screen.
Step 8 – Refine results (located in the upper left of the results pane) lets you further narrow down which feature types will be listed in the results. This is similar to selecting “Results for…” in Step 4, but applies the filter after identifying, instead of before.
- If you have multiple features or layers turned on you will get a lot of attributes that may not be parcels in the returned results, such as street centerlines, utilities, trees, etc.
- Click refine results and uncheck the features types which are not parcels
Step – 9 View selected parcels for export
- Clicking on “Select All” in the results pane will highlight all features which are currently identified. Selected parcels will highlight on screen to verify the buffer captured all intended parcels. (choose “Select None” to toggle off the highlighted parcels).
- You can create a print of your selection at any time and it will display the selected parcels and buffer.
Step 10 – Export results to a .xls spreadsheet
- Select table view at the top of the results pane (next to refine results).
- After selecting table view, Export to CSV now is available for the refined parcel list. Once selected you can save the .xls file to your computer.
- The file you save will be a *.zip file as it may contain multiple files with related information on the selected features.
Step 11 – Clear buffer
- Use “select none” in the results pane if you highlighted features. This will remove the highlights.
- Next go to the “Draw & Print” tab at and select “Clear All” at the far left of your screen to remove the buffer shape. (You can also simply sign out if you have no further work in GIS.)
