The Main Map Window will zoom to the data location unless a selection is needed from the column on the right. In that case, select an entry. The lightbulb button is lighted.

layer files

  • Clicking lightbulb opens the selected shape. One of two things will happen:
  1. A new shapefile will be added to the left-hand table, or
  2. A dialog (Grid Layer Dialog) will open for viewing/interacting with the data associated with the shape.

grid dialog

  • close closes the selected shapefile.
  • If infois enabled, clicking it will open a browser page with additional information on the data.
  • Clicking zoom in will zoom to the bounding box of the selected shape (right table). If the selected shape is a dimensionless point (type = 1, 11, or 21), the zoom will not do anything. Control+click on the selected shape to de-select it.
  • Click the Layers layers button on the main tool bar to reopen/close the Layers dialog as needed.
  • The table on the left is a list of the shapefiles that have been imported. The table on the right is the attributes table for each shape in the selected shape file.
