Attribute Table

      The Attribute Table widget displays a tabular view of operational layers' attributes. It displays at the bottom of your web application and can be opened, resized, or closed. When more than one layer's attributes display, multiple tabs automatically generate in the attribute panel allowing you to switch among the attribute tables. You can use the widget's configuration window to specify which layer or layers are included in the tabular view, which fields show, and if the tabular view can be exported.

• If the search was configured to use Unique then a dropdown list will be presented of all unique values for the configured field. A progress indicator will be presented to show that the widget is busy working with the unique values as highlight in the image above.
• If Ask for values is specified at configuration time, a text box displays prompting you for new value for the parameter. The default value shows in the box initially.
• If you check the Limit results to maps extent. then the search results will be limited to features that intersect the maps current extent.
• If you checked the Value is required to be entered to enable search then the required expression value will be indicated with "*Required".
• If the expression value is defined as unique values or the field has a coded domain then the drop down list will not contain a blank value like it does when the field is not required.

• If you check on the enable multi-part graphics then when you complete drawing on graphic you and can continue to draw the same geometry type and once you have drawn all the graphics you wish to search by then you can click Search to execute the search.
• If you don't check on the enable multi-part graphics then when you complete drawing on graphic the search is automatically executed.
• If you choose the point graphic draw tool and are attempting to search for line or point feature then you should use the Add search tolerance to point selection.
• If you choose you can buffer the graphics after it is drawn but before the search occurs by checking the Buffer Graphic checkbox and adjusting the distance and units if desired.
• If you choose to add or remove from the current search results using graphical searches as well as By Value searches.

By Spatial

      The By Spatial view has buffering options, a dropdown list of predefined search layers and spatial operation buttons.

• If have already completed an attribute or graphical search then you can use the spatial search to search for other features that have a spatial relationship to your previous search results.
• If you click the Apply Buffer button than a buffer will be added around your existing search results. This buffer can be used as the geometry of your spatial search instead of the existing search results geometries.
• Choose the layer that you will search for the spatial relationship with your existing search results or buffer.
• Finally select the spatial relationship button that you want to execute. (i.e. entirely contained in).
• A common workflow for using the By Spatial search would be to search for a parcel and determine the parcels that are within 1000 feet of the original parcel. To do this you would follow these steps:
  1. Search the properties layer by Parcel ID using the By Attribute Search.
  2. Switch to the By Spatial view and buffer that result by 1000 feet.
  3. Select the properties layer from the drop down layer list and click the intersected by button.

Results

     The Results view displays the features returned from the search, and use an alternating color scheme.

• Click on an individual search result will zoom the map to that result and display the popup for that result.
• If the results layer has links configured than the link text or link image will appears in the results.

Graphic Measure

Select Measure Type: Use this portion of the dialog to select which type of shape you would like to draw and measure. The selected tool will be highlighted by displaying a lighter gray background. With a tool selected you are ready to draw on the map. When you have completed drawing the desired shape, no tools will be selected. Clicking the Clear link will remove all measured shapes from the map.

Preview: Displays what the line or polygon will appear when drawn on the map. As you make changes to the color or size, it will be reflected in the preview.

Predefined Symbols: These lists display predefined symbols to give you a good starting point for the shape you are going to draw. You can be more specific about color, line width or type as shown below.

Color, Outline Color, Font Color: Click the associated color box to display a color picker dialog that will let you choose any color. You can be very precise with color values using the RGB, HSV or HEX settings. This will change the color of the line draw, the fill of a polygon or the color of the text used for measuring.

Transparency: Use the slider to set how transparent a line or or fill will be when a shape is drawn.

Text Properties: The preview will display what the text will look like for each measure displayed on the map when drawing a new shape. The preview text will also interactively update as a segment is being drawn, as will the Text textbox. You can adjust the size of the text by keying in a numeric value or using the up and down arrows to increase or decrease the size. Clicking the Font Color box will display a color picker that will allow you to choose the color of the text used for measuring.

Area Units and Distance Units: Use the drop down boxes to select your preferred units of measure.

Show Measurement Totals: Displays the total of all drawn segments and the area if the draw geometry is a polygon.

Editing Shapes

You can edit a drawn shape by clicking or tapping on it. This exposes vertex points that you can drag to new locations. As you drag, the measurements for the segments associated with the vertex will update. When you finish dragging, the summary for total distance and area will also be updated.


There are two types of vertices. The gray dots represent a regular vertex and the white dots represent a ghost vertex. Dragging a ghost vertex splits the segment into two new segments with new measurements. You can repeat this and create as many vertices as needed for your measurement.


You can delete a vertex by right clicking on it. This will display a delete button. Click the delete button and the vertex will be deleted. The measurements for the drawn shape will be updated to reflect the new segment.

You can also change the properties of the shape. With a shape selected for editing, you can change the line width, line or fill color and line style. You can also change the color and size of the text for the shape selected for editing.

Buffer Analysis

 The Buffer Analysis widget allows you to locate point of interest on the map and analyze information from different layers within a specified distance of the subject item.

♦ Click the Buffer Analysis widget icon to open it. The widget displays at the bottom of the map.
♦ To specify a buffer distance of interest, drag the slider or manually input a value and press the enter key.
♦ Locate an item on the map by using one of the Buffer drawing tools. Click the clear buffer icon to clear the current buffer.
♦ Click other tabs�Fire Stations, Hospitals, Librarys, etc to view the analyzed information for specified layers. You can scroll the widget   panel horizontally to view additional results.
