Selecting Features

You can use the Select Features tool to interactively select features from a layer on the map to display attributes and/or to buffer.  A selection can be made by drawing a point, line, polygon, or rectangle.  To select features using one of these tools, open the Select Features dialog and then use the appropriate tool.

How to open the Select Features dialog

  1. ​In the Toolbar click the Select Features icon.
  2. This opens the Select By element dialog.
  3. See the instructions below depending on whether you want to select by point, line, polygon or rectangle.
  4. After selecting, you can close the Select By dialog by clicking on its Close icon in the upper right corner.

How to select by point

  2. To set the layer from which features will be selected, select a layer from the layer drop-down list.
  3. Choose a Selection Method from the drop-down list.  Method options include; Add to Selection, New Selection and Remove from Selection.

  5. Move the cursor to the second point of the line. If you are creating a single straight-line segment, double-click at this location to end the line. Otherwise click once with the left mouse button.
  6. If creating a line with multiple segments, continue clicking at vertices to add segments.
  7. At the last vertex, double-click to end the line.
  8. Features intersecting the line graphic will be selected and highlighted on the map.  The Records Selected dialog will appear listing the attributes of each feature in the selected set.

How to select by polygon

  3. Click the second point of the polygon.  The first segment draws and the polygon now stretches to the current position from the last point as well as to the initial point.
  4. Continue adding points (vertices) of the polygon.  New vertices add segments connecting to the previous vertex.
  5. At the last vertex in the polygon, double-click the mouse.  You do not need to click at the original point again.

Tips & Tricks

Before double-clicking to finish drawing a line or polygon you can remove points (vertices) that make up the geometry of the line or polygon by right-clicking the mouse.  This is a great way to undo points that you placed in the wrong location.
