Instructions for use
Create a rectangular Region Dataset grid that can be used as an index to specify the index page using Map Series.
Application Scenario
The generated grid face data can be used for pages of specified series of view frames in Map Series, and the adjacent view frame name of each grid can be calculated based on the data.
Function Entry
- Open the map to be indexed in Map: Map tab-> Drawing-> Create Grid Index.
- Open the map to be indexed in Layout: Object Operation tab-> Map Series-> Create Grid Index.
Parameter Description
- Grid Parameters
- Coordinate Origin X: Specifies the coordinate X value of the origin of the lower-left corner of the output grid Dataset. If Bounds Dataset is specified, the default value is determined by the union of these feature ranges. If Bounds Dataset is not specified, the default value is the coordinate X value of the lower-left origin of the Current Map.
- Coordinate Origin Y: Specify the coordinate Y value of the origin at the lower left corner of the output grid Dataset. If Bounds Dataset is specified, the default value is determined by the union of these feature ranges. If Bounds Dataset is not specified, the default value is the coordinate Y value of the origin at the lower left corner of the Current Map.
- Width: The width of a single mesh index face. The program will be based on the specified number of lines, according to the range of automatic calculation, also support the specified width.
- Height: The height of a single mesh index face. The program will automatically calculate according to the range based on the specified number of columns, and also support the specified height.
- Rows: Specifies the number of rows created along the Y direction of the origin.
- Columns: Specifies the number of columns created along the X direction of the origin.
- Start Page Number: Each grid index element will be allocated to a continuous page, and the dimension will start from the face element at the lower left corner of the output grid. The page number of the start page can be specified, and the default value is 1.
- Bounds Dataset: It is used to define the range of the surface grid to be created. It supports point, line and Region Dataset.
- Generates a mesh region that intersects the range dataset: Refers to restricting the output grid index Dataset to the area only intersecting the input Bounds Dataset. Bounds Dataset is specified and this setting is checked. The intersection of the Bounds Dataset with the map will be used to generate the grid index.
If the grid index Dataset output is not checked, a regular grid will be generated according to the specified number of rows/columns.
Next, you can perform Calculate Adjacent Fields operations on the index grid.
Application example
Sichuan Province is used as the Bounds Dataset, the row and column numbers are set to 6, and the Other Parameters are defaulted. If the Generates a mesh region that intersects the range dataset check box is checked, The results are shown in Figure 1 below.
If the Generates a mesh region that intersects the range dataset check box is not checked, the generated result is a 6 * 6 regular grid, as shown in Figure 2 below.
