Suppress Spot Heights (Defense Mapping)
Récapitulatif
Esri Defense Mapping cartographic production tool that suppresses the symbol for spot heights based on the input product type. Suppressing a symbol refers to setting a representation invisible.
Utilisation
This tool uses the Make Representations Invisible tool to suppress spot height symbols.
The Input Area of Interest must have an NRN field. The NRN field uniquely identifies an area of interest within the input area of interest features.
-
Suppression uses a search radius to locate spot heights that are close to one another. Spot heights are sorted by elevation in descending order. This tool suppresses lower spot heights that fall within the search radius of a higher spot height.
Suppression refers to making a representation within a feature class invisible. If no representation has been defined on the Input Spot Height Features, the tool returns Error 000735: Representation: Value is required.
Syntaxe
Paramètre | Explication | Type de données |
Input_Area_of_Interest |
A feature layer that describes the processing extent. The tool suppresses spot heights found in each feature in the feature layer. Select features in this feature layer to limit the processing area. | Feature Layer |
Product_Type | Used with Data_Model_Version to determine the Defense Mapping specification. The specification equates to a representation name in a Defense Mapping data model.
| String |
Data_Model_Version | Used with Product_Type to determine the Defense Mapping specification. The specification equates to a representation name in a Defense Mapping data model.
| String |
Search_Distance |
Search distance to locate spot heights that are close to other spot heights. Spot heights found within this distance will be made invisible. | Linear unit |
Input_Spot_Height_Features |
An existing Defense Mapping point feature layer in which representations will be made invisible. | Feature Layer |
