Make Defense Grids and Graticules (Defense Mapping)
サマリ
Generates a grids and graticules layer for Esri Defense Mapping products. This tool supports the creation of single, dual, and zipper zone grids. It simplifies grid creation by automatically populating several parameters based on a selected feature and an input grid type. It determines zone type and the correct grid .xml template used to generate the grids and graticules layer. It also determines a grid's primary and ancillary coordinate system and estimates reference scale and annotation mask margin.
使用法
Grid templates can be found in the <ArcGIS installation directory>\GridTemplates\DefenseMapping directory.
Input Area of Interest can only be a single polygon feature from a single feature layer. With a stand-alone script, you must use the Select Layer By Attribute tool.

The Primary Coordinate System is predefined in all Defense Mapping grid templates.
The Ancillary Coordinate System is often predefined in Defense Mapping grid templates. Dual grid templates require you to manually select the appropriate projected coordinate system.
During execution, this tool calls another geoprocessing tool, Feature Outline Masks. This creates a mask used to hide features along the edge of the grid. The mask improves cartographic display of annotation along the grid's edge. The output of Feature Outline Masks is added to the grid Feature Dataset.
構文
| パラメータ | 説明 | データ タイプ |
in_aoi_features | The feature layer that contains the selected feature used to determine the extent of the grid layer. The grid is created within this extent. | Layer |
grid_type | Indicates the type of Defense Mapping cartographic product that will include the grid.
| String |
template | Path to a grid .xml definition template. These templates store graphic properties for each grid layer. You can create new templates using the Production Mapping Grids and Graticules Designer or use existing templates located in the ArcGIS installation directory. | File |
in_workspace |
Workspace used in conjunction with the input Feature Dataset. | Workspace |
in_dataset |
The feature dataset that will store the features. This tool will create the feature dataset if it does not exist. Grid-specific feature classes will also be created if they do not already exist. If they already exist, and a grid with the same name and type as the one being created also exists, it will be overwritten. | String |
use_field | Indicates whether a field name or string is appended to the end of the name of each feature class in the feature dataset. This allows you to store multiple grids in the same feature dataset.
| Boolean |
grid_field | The name of the field from in_aoi_features whose value is used as the grid name. This value is appended to the name of each feature class in the grid dataset. It is recommended that the NRN field be used. | Field |
grid_string |
The name for the cartographic grid created that allows for distinction between grids stored in the same feature dataset and set of feature classes. | String |
primary_coord |
Coordinate system for the grid layer being created. Typically, it will be the coordinate system of the final product or data frame. This coordinate system must be a projected coordinate system. | Spatial Reference |
ancillary_coord |
A secondary coordinate system in which grid components can be created. | Spatial Reference |
reference_scale |
The scale at which the grid is created and should be viewed. When the reference scale from the XML grid definition file is defined as Use Environment, the reference scale is derived in the following order:
| Double |
mask_margin | The amount of space that exists between the side of the annotation and the mask polygon feature. The units can be defined in page or map units. The value is composed of a number and unit of measurement. | Linear unit |
anno_feature_class |
Name for the annotation mask feature class. | String |
update_data_frame (オプション) | Indicates if the tool will update the data frame and layout using the grid settings.
| Boolean |
