Suppress Spot Heights (Defense Mapping)

Summary

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.

Usage

• 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.

Syntax

SuppressSpotHeights_defense (Input_Area_of_Interest, Product_Type, Data_Model_Version, Search_Distance, Input_Spot_Height_Features)

Parameter	Explanation	Data Type
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. MDG50_MGCP —Representations specific to product MDG50_MGCP MDG50_TLM —Representations specific to product MDG50_TLM MDG100_MGCP —Representations specific to product MDG100_MGCP MDG100_TLM —Representations specific to product MDG100_TLM LDG50_NSG —Representations specific to product LDG50_NSG LDG100_NSG —Representations specific to product LDG100_NSG	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. TRD2 —Representations specific to MDG* product types TRD3 —Representations specific to MDG* product types TRD4 —Representations specific to MDG* product types LTDS_4_0 —Representations specific to LDG* product types LTDS_5_0 —Representations specific to LDG* product types	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

Code Sample

SuppressSpotHeights example (Python window)

The following code sample demonstrates how to use the SuppressSpotHeights function.

# set gp environment
arcpy.env.workspace="c:/data/defense.gdb"
arcpy.env.addOutputsToMap = True

# local variables
areaOfInterest = "C:/Program Files (x86)/ArcGIS/EsriDefenseMapping/Desktop10.1/ReferenceData/MapIndex.mdb/MapIndex/TLM100_Index"
areaOfInterestLyr="TLM100IDX"
whereclause="NRN='V695X1856'"
productType="MDG100_MGCP"
dataModel="TRD2"
searchDistance="1300 meters"
spotHeightFeatures="Features/ElevP"
spotHeightFeaturesLyr="ElevPLyr"

# make a feature layer from area of interest and spot heights
arcpy.MakeFeatureLayer_management(spotHeightFeatures,spotHeightFeaturesLyr)
arcpy.MakeFeatureLayer_management(areaOfInterest,areaOfInterestLyr)
arcpy.SelectLayerByAttribute_management(areaOfInterestLyr,"NEW_SELECTION",whereclause)

desc=arcpy.Describe(areaOfInterestLyr)
fidlist=desc.FIDSet.split(";")
if len(fidlist) == 1:
    # suppress the spot heights
    arcpy.SuppressSpotHeights_defense(areaOfInterestLyr, productType, dataModel,searchDistance,spotHeightFeaturesLyr)
