How to select attributes within a distance

In lab 5, you are asked to label the campgrounds within 200 m of overfished lakes as closed. In order to select the campgrounds you have to use SQL.

  1. Go to Selection on the top bar, click Select By Attribute.
    1. Layer = Lakes
    2. SQL = Fish Density <= 10
    3. Click Ok
  2. Go to Select by Location.
    1. Select features from
    2. Target Layer = Campground
    3. Source Layer = Lakes
    4. Click Use Selected Features (this enables you to select only the lakes that are in the previous selection)
    5. Spatial selection method = “are within a distance of the source layer feature”
    6. Search Distance = 200 meter

You now have only the campgrounds that are within 200 meters of the low density lakes selected.
