Zoom In - This button will zoom the map in by either clicking on the map or drawing a rectangle to which the map will be zoomed to the extent of the rectangle.

Zoom Out - This button will zoom the map out by either clicking on the map or drawing a rectangle.  When drawing a rectangle while zooming out, it is important to note that a small rectangle will zoom out a larger distance then a large rectangle will.

Pan - This will move the map in all directions.  Hold the mouse down while moving the mouse to pan around the map.

Full Extent - This will zoom the map out to the full extent (i.e. the viewing area where all data is visible) of the map.

Identify - This is used to get more information from a particular layer (which will be displayed in the Result Pane).  First note that when clicking this button a popup will appear (see Figure 2).  First a layer must be selected;  in this case "roadcl" is selected which is the center lines for the roads.  If unsure what layer should be selected, guess and see what comes up selected after the identify has completed.  Once the layer is selected, click on the map near the object to be retrieved.  It is important to note that the location clicked on the map does not have to be exact, GeoBlade Web automatically figures a margin of error.  After clicking on the map, loading text should appear in the results pain (see Figure 3).  Like all movable popups, holding down the left mouse button while moving the mouse on the top strip will move the popup where ever desired within the browser.  The close button on the top left, will hide this popup.

Once it is done, the road will be selected on the map (Figure 4) and the results will be in the Results Panel (Figure 5).  For more information about the Results Panel, see the Results Panel.

Measure - This can be used to measure an area, length or the X, Y coordinate pair.

Figure 6.  The Measure Popup

•	Measure Point - Simply click anywhere on the map to retrieve the X, Y coordinate pair.

•	Measure Polyline - Click on the map to start drawing the line.  When you want to place a point, click on the map again. to end the polyline, double click

•

Measure Polygon - Click on the map to place the initial point.  Place at least 2 more points to create a triangle and as more points are placed the polygon outline will be drawn.  Double click to finish creating the polygon and get the results.  It is important to note that with polygons, both the perimeter and area will be returned.

Spatial Search - This is useful for finding all of a specific feature that is enclosed within a polygon or that intersects with a line (for example a street).  To perform a spatial search, is nothing more then the combination of an Identify and Measure.  First select the layer that the spatial search will return records for (just like an Identify).  Once a layer is selected, use one of the shapes selection buttons to draw a shape (like the measure tool) that will find all features that intersect with the given shape.

Generate URL - This is useful for generating a url to the current extent of the map.  Currently any tool that generates a result is not saved within the generation of the URL.  To generate a url, click on the "Generate URL" button (see Figure 8) and a URL should appear after a few seconds.

Figure 8.  The Generate URL popup.

Print - Printing is one of the most important part of maps.  Clicking on the print button shows the Print Popup (see Figure 9).  Simply enter a title for the map, select the page size, select the map format that will be used (if there are multiple present) and click "Generate Print".  It is important to note that Adobe Reader must be installed.  To download Adobe Reader (it is a free install) visit: http://www.adobe.com/products/acrobat/readstep2.html.  If your browser blocks popups, you will need to enable those first.

Figure 9.  Generating a Printout

Once the "Generate Print" button is pressed, the map will be retrieved and a "Please wait" message will appear (see Figure 10).

Figure 10.  The Please wait screen when generating a print.

When the print is generated it will popup in a browser window with the adobe file.

Buffer Feature - This is useful to objects that are near other ones.  An example might be that a realtor is trying to help a customer find land for sale near a particular  lake.  To perform this search, enter parcels for the "select records from" and enter 2,000 feet for the distance and the last drop down select "waterbodies" (see Figure 11).

Figure 11.  Buffering waterbodies by 2,000 feet.

The result for this buffer feature looks like Figure 12.  Notice how the shape that was buffered is also present visually in the map making it easy to determine where the buffered area covers in addition to all selected parcels.
