Setting values for the feature properties

You can define values to be used for populating line and polygon features when they are created. On the Defense Mapping Properties dialog box, on the Geometry Reporter tab, thresholds can be specified for the minimum length, perimeter, area, and z thresholds, respectively. These values can be used to indicate whether the selected geometry is meeting a criteria for a feature based on a product specification. For example, if all building polygons should be at least 25 meters square, you can use 25 as the minimum area threshold.

Examples of thresholds used with the Geometry Reporter

If you are using a minimum z-value threshold, features that have a part with a z-value below the minimum threshold are indicated as errors in the Geometry Reporter. This means that the z-value attribute of the feature could have a value that is above the minimum value, but one of the vertices or the point itself does not. For instance, if the minimum z-value for features is 600 and the zv2 value for a contour is 600, a Z warning can still appear on the Geometry Reporter dialog box if any of the vertices have a z-value that is less than 600.

This tool can be used in conjunction with Data Reviewer, or any tool that allows you to select a single feature.

Pasos:
  1. Start ArcMap.
    SugerenciaSugerencia:

    If the ArcMap - Getting Started dialog box appears, you can open a new or existing map document. You can also check the Do not show this dialog box in the future check box and click Open.

  2. On the main menu, click Customize > Toolbars > Defense Mapping.
  3. On the Defense Mapping toolbar, click Defense Mapping > Options.

    The Defense Mapping Properties dialog box appears.

  4. Click the Geometry Reporter tab.

    This tab allows you to define minimum thresholds on polygon and polyline features.

    NotaNota:

    All values must be defined in meters.

  5. If necessary, check the Apply Minimum Length Threshold check box.
  6. Type a value in the Apply Minimum Length Threshold text box.

    The threshold represents the minimum length for the feature.

  7. If necessary, check the Apply Minimum Perimeter Threshold check box.
  8. Type a value in the Apply Minimum Perimeter Threshold text box.

    This value represents the minimum perimeter for a polygon.

  9. If necessary, check the Apply Minimum Area Threshold check box.
  10. Type a value in the Apply Minimum Area Threshold text box.

    This value represents the minimum area for a polygon.

  11. If necessary, check the Apply Minimum Z Threshold check box.
  12. Type a value in the Apply Minimum Z Threshold text box.

    This value represents the minimum z-value for a feature.

  13. Click OK.

When thresholds are set, the Geometry Reporter tool shows the appropriate parameter in green if the feature is above the threshold and in red if the feature is below the threshold.
