Filter Data

The ArcGIS Online Map Viewer allows you to filter your data by multiple criteria. This allows you to limit which features draw and focus on only certain subsets of your data that are of interest to you. In addition, Analysis Tools take note of current filters when generating their output.

In this lab you will focus in on Rail Stops on the Blue Line and generate buffers around only those stops.

Steps

  1. Go to www.arcgis.com and login.

  2. Use Search > Search for Layers to find the PDX_Rail_Stops layer by al_geodev.

  3. Click Open > Add layer to new map.

    3. Type B into the text field (this is how the data is encoded for the Blue Line).

    4. Click Apply Filter.

  2. Click PDX Rail Stops > Perform Analysis > Use Proximity > Create Buffers.

    1. Choose to buffer by Distance and set the size to 1 Miles.
