The following brief tutorial may be of assistance.

ICONS used in the following text.

Hand tool
Quick Find Tool (Magnifying Glass )
Property owner
Redlining tool (Pencil)
Straight line selector
Basemap Blender
Zoom Tool (displayed in the vertical position on the screen only)

When the screen first appears, there are four large scroll icons on the upper left of the screen.  Above them is a "Basemap Blender" or slider and to the left is the "Zoom Tool" scale which is used to move in or away on from the map.  The cursor becomes a "Hand Tool" which appears in the middle of the screen.  Hold down the left mouse button to drag the map in any direction.

 The scrolls are:

  1. Aerial view.  You can select which aerial view of the area you wish to view.  There are 4 selections (1996, 2001, 2006 and 2007).  The Basemap Blender may be used to move from one map to the next.
  2. View houses with street names and numbers shown.  Most people will probably use this view.
  3. View topographical information on top if the current view.  Since Terrace Park is mostly flat, there are few contour lines.
  4. View buildings with Parcel Numbers, Lot Dimensions.  Planning personnel will probably use this view most of the time.

    This view is most interesting, but possibly not too useful in Terrace Park since there have been few significant building changes over the past 10 years.  However, if you are viewing downtown Cincinnati, you can use the Baseline Blender (slider) and see the stadiums being built, torn down and re-built.


  1. First you can drag the map in any direction.  Terrace Park is on the right hand side of Hamilton County.
  2. To move in and out, use the Zoom Tool slider on the left side of the screen.
  3. There are two ways to view Terrace Park
    Move around the map by following steps 1 and 2 above.
    Use the "Quick Find" icon at the top of the screen.  Click on the magnifying glass to open a list of communities within Hamilton County.  Terrace Park will be towards the end of the list.  Click on Terrace Park. 
    The following image will appear.  Then follow steps 1 and 2 above.


  1. Select the redlining and measuring (pencil) icon on the top of the screen.
  2. A dialogue box appears.

3.    Click on the Redlining tool to draw a straight line.
4.    Position the cursor over the beginning point of of the line and left click ONCE.
5.    Position the cursor to the end point of the line and left click TWICE.  The distance from the beginning to the end is calculated and displayed.
       In this example the distance from the edge of the house to the lot line is 21.89 feet.


You can search for a specific property.  All information comes from the Hamilton County Auditor's Office.  Enter the property owner's name in the box at the top of the screen.    The system will go directly to that property and the property lines will be highlighted in a light blue color.  In addition, a Property Report will be displayed.


There are many other options available so experiment to discover the full capabilities of this mapping system.
