Make Grids and Graticules Layer (Cartography)
汇总
Creates a grouped layer of feature classes depicting grid, graticule, and border features using predefined cartographic specifications. Grid layers are ideal for advanced grid definitions which are scale and extent specific.
Each grid layer can be composed of a mask polygon, clip polygon, segments (line), gridlines (line), ticks (line), endpoints (point), points (point), and annotation feature classes. These components are stored as features in corresponding feature classes. These features classes are saved within a specified feature dataset in a geodatabase. There are seven feature classes that store the basic components of a grid. Each feature class is named with a three letter prefix that helps identify the grid component the feature class holds. These feature class/components are:
- ANO_ is the annotation feature class
- EPT_ is the endpoints feature class
- GLN_ is the gridlines feature class
- MSK_ is the masks feature class
- PNT_ is the points feature class
- SEG_ is the segments feature class
- TKS_ is the segments feature class
These feature classes can hold information for multiple grids. An eighth feature class (GRD_) contains organization information such as map name and grid types that are used to organize your grids.
The grid definition template is stored in a predefined XML file. This file stores specification properties for each grid, such as the number, color, and line weight of gridlines. When the definition template is applied, features are created according to the specification based on the current extent or extent of a selected feature (area of interest), scale and coordinate systems.
用法
This tool is designed for projected maps that will be printed or exported. It is not meant for creating grids or graticules that dynamically update as the user navigates the map.
-
You must input an area of interest to determine the extent of the grid layer to be created. If you are using a feature layer to define the area of interest, it must be a polygon feature class or polygon layer.
-
In the Make Grids and Graticules Layer dialog box, once the Grid Template (XML file) parameter is defined, hover over or click the context-sensitive area immediately to the left of the parameter name to display grid type, description, rotation type, and scale type information for the defined XML grid definition template.
The grid template XML file specifies grid components depicting measurements or locations for a primary and ancillary coordinates systems. All coordinate systems specified must share a common geographic coordinate system. If you want to change the primary coordinate system to one that uses a different datum than the default, say for example you change the coordinate system from one that uses WGS 1984 to one that uses NAD 1983, you must change each default ancillary coordinate systems to NAD 1983 as well.
The grid template XML file creates grid components for up to four ancillary coordinate systems. The number of ancillary grids is specified by the XML file. You cannot add or delete ancillary coordinate systems, but you can override the default values.
The Primary Coordinate System must be a projected coordinate system.
Ancillary coordinate systems can be either a projected coordinate system or a geographic coordinate system.
The spatial reference of the Input Feature Dataset should have the same geographic coordinate system as specified by the grid template XML file.
The spatial reference of the Input Area of Interest should have the same geographic coordinate system as specified by the grid template XML file.
If you are accessing the tool from ArcMap checking the Configure data frame and layout using grid settings checkbox ensures that the data frame on the layout is adjusted to best fit the created grid. The data frame's coordinate system, scale, rotation, size, extent, and clipping may be altered to match the XML grid specification. This setting is only available when the tool is executed from ArcMap's layout view and is not being run in the background. The default is to have this check box unchecked, which will not change any of your data frame properties.
语法
| 参数 | 说明 | 数据类型 |
in_template |
The XML grid definition template stores the specification's graphic properties for each grid layer. In addition to the graphic properties, which cannot be altered before execution, the definition has specific default values, exposed as parameters, that can be modified before execution. Template files are located in the \ArcGIS\Desktop10.0\GridTemplates directory. Additional grid templates can be obtained and shared using the ArcGIS Resource Center. The ArcGIS Production Mapping extension provides a grid designer that allows you to create new templates as well as modify existing ones. | File |
in_aoi |
The feature layer or x,y extent used to determine the extent of the grid layer created.
 注意:The only extent options valid for this tool are "Default", "As Specified Below" or "Same as Display". Selecting any other option will result in an error. | Feature Layer; Extent |
input_feature_dataset |
The feature dataset that will store the features. Grid-specific feature classes will 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. 注意:A grid with the same name and type as the one created will always be overwritten, regardless of the GP environment. | Feature Dataset |
output_layer |
The grouped layer of feature classes depicting grid, graticule, and border features. Each grid layer can be composed of a mask polygon, a clip polygon, segments(line), gridlines(line), ticks(line), endpoints(point), points(point), and annotation feature classes.
注意:This is an in-memory layer that you must save in the ArcMap document or as a layer file. | Group Layer |
name (可选) |
The name for the cartographic grid created that allows for distinction between grids that are stored in the same feature dataset and set of feature classes, expressed in one of the following formats:
| String; Field |
refscale (可选) |
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 |
rotation (可选) |
The rotation angle for the grid components. Rotation is used to provide annotation that is level with the page. Unless otherwise specified, rotation is calculated using the area of interest feature. When the rotation type from the XML grid definition file is defined as "Use Environment", the rotation is derived in the following order:
| Double |
mask_size (可选) |
The mask is a polygon feature that forms an outer ring around the extent of the neatline and is used to mask data that falls in the area reserved for coordinate labels. Mask size defines the width of the polygon mask feature in map or page units. The data frame may have to be resized to fit around the edge of the mask while including the coordinate labels. | Linear Unit |
xy_tolerance (可选) |
The minimum tolerated distance between geodatabase features, expressed in linear units. This value is defaulted from the value set in the XML. You can set the value higher for data with less coordinate accuracy and lower for data with extremely high accuracy. Features that fall within the set XY tolerance will be considered coincident. | Linear unit |
primary_coordinate_system (可选) |
The grid template XML file creates grid components depicting coordinates or locations for a primary coordinates system and up to four ancillary coordinate systems. The number of ancillary grids is specified by the file. You cannot add or delete ancillary coordinate systems. All coordinate systems specified must share a common geographic coordinate system. If you want to change the primary coordinate system to one that uses a different datum than the default, say for example you change the coordinate system from one that uses WGS 1984 to one that uses NAD 1983, you must change each default ancillary coordinate systems to NAD 1983 as well. This is the primary 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 |
configure_layout (可选) |
Adjusts the data frame settings to ensure they match the grid layer. The data frame's coordinate system, scale, rotation, size, extent, and clipping may be altered to enforce consistency. This setting is only available when the tool is executed from ArcMap's layout view and is not being run in the background. The default is to have this check box unchecked.
| Boolean |
ancillary_coordinate_system_1 (可选) |
The grid template XML file creates grid components depicting coordinates or locations for a primary coordinate system and up to four ancillary coordinate systems. The number of ancillary grids is specified by the file. You cannot add or delete ancillary coordinate systems. All coordinate systems specified must share a common geographic coordinate system. If you want to change the primary coordinate system to one that uses a different datum than the default, say for example you change the coordinate system from one that uses WGS 1984 to one that uses NAD 1983, you must change each default ancillary coordinate systems to NAD 1983 as well. This is the first ancillary coordinate system. | Spatial Reference |
ancillary_coordinate_system_2 (可选) |
The grid template XML file creates grid components depicting coordinates or locations for a primary coordinates system and up to four ancillary coordinate systems. The number of ancillary grids is specified by the file. You cannot add or delete ancillary coordinate systems. All coordinate systems specified must share a common geographic coordinate system. If you want to change the primary coordinate system to one that uses a different datum than the default, say for example you change the coordinate system from one that uses WGS 1984 to one that uses NAD 1983, you must change each default ancillary coordinate systems to NAD 1983 as well. This is the second ancillary coordinate system. | Spatial Reference |
ancillary_coordinate_system_3 (可选) |
The grid template XML file creates grid components depicting coordinates or locations for a primary coordinates system and up to four ancillary coordinate systems. The number of ancillary grids is specified by the file. You cannot add or delete ancillary coordinate systems. All coordinate systems specified must share a common geographic coordinate system. If you want to change the primary coordinate system to one that uses a different datum than the default, say for example you change the coordinate system from one that uses WGS 1984 to one that uses NAD 1983, you must change each default ancillary coordinate systems to NAD 1983 as well. This is the third ancillary coordinate system. | Spatial Reference |
ancillary_coordinate_system_4 (可选) |
