ArcMap

Grid XML Selector

Summary

ArcGIS Defense Mapping cartographic production tool that returns the correct grid .xml file for a given grid type and area of interest (AOI). You can use the returned .xml file in the Make Defense Grids and Graticules or Batch Make Defense Grids and Graticules tools.

Usage

  • Grid .xml files are installed under <ArcGIS installation directory>\GridTemplates\DefenseMapping. This tool will return a path to a file in this location.

  • Grid AOI requires one selected polygon feature. If you select no features or more than one, the tool returns the error Requires exactly one feature to be selected.

Syntax

arcpy.defense.GridXMLSelector(in_aoi_features, grid_type)
ParameterExplanationData Type
in_aoi_features

A polygon feature layer that must contain exactly one selected feature. The selected feature defines an area in which a grid may be created. The extent of the selected feature and the cartographic product type determine which grid .xml file the tool returns.

Feature Layer
grid_type

Indicates the type of Defense Mapping cartographic product that will include a grid. Different product types require different grid styles. The cartographic product type and the extent of the input area of interest determine which grid .xml file the tool is going to return.

Code sample

GridXMLSelector example (Python window)

The following code sample demonstrates how to use the GridXmlSelector tool.

import os

# Set gp environment
arcpy.env.addOutputsToMap=True

# variables for tool
idx="C:/Program Files (x86)/ArcGIS/EsriDefenseMapping/Desktop10.2/ReferenceData/MapIndex.mdb/MapIndex/TLM50_Index"
idxLayer = "TLM50_Index"
where="[NRN] = 'V795X22561'"
product="TLM50"

# Make a feature layer from the TLM50_Index feature class
if arcpy.Exists(idxLayer):
    arcpy.Delete_management(idxLayer)

arcpy.MakeFeatureLayer_management(idx,idxLayer)

# Select a feature that will define the AOI
arcpy.SelectLayerByAttribute_management(idxLayer,"NEW_SELECTION", where)

# return a grid XML file from this AOI and product
result = arcpy.GridXmlSelector_defense(idxLayer, product)
gridXml = result.getOutput(0)
print gridXml
print os.path.exists(gridXml)
