Feature Description
Creates a rectangular region dataset grid that can serve as an index for specifying index pages using Map Series.
Application Scenario
The generated grid region data can be used for pages of specified series of view frames in Map Series. Adjacent view frame names for each grid can be calculated based on the data.
Feature Entry
- Open target map in Map view: Map tab-> Drawing-> Create Grid Index.
- Open target map in Layout view: Object Operation tab-> Map Series-> Create Grid Index.
Parameter Description
- Grid Parameters
- Coordinate Origin X: Specifies the X-coordinate value of the lower-left origin for the output grid dataset. If Bounds Dataset is specified, default value is determined by the union of feature extents. Otherwise, defaults to the X-coordinate of current map's lower-left origin.
- Coordinate Origin Y: Specifies the Y-coordinate value of the lower-left origin for the output grid dataset. If Bounds Dataset is specified, default value is determined by the union of feature extents. Otherwise, defaults to the Y-coordinate of current map's lower-left origin.
- Width: Width of a single grid index region. The program automatically calculates based on specified rows and extent range, while also supporting manual input.
- Height: Height of a single grid index region. The program automatically calculates based on specified columns and extent range, while also supporting manual input.
- Rows: Specifies the number of rows created along the Y-axis from the origin.
- Columns: Specifies the number of columns created along the X-axis from the origin.
- Start Page Number: Assigns consecutive page numbers to grid index elements, starting from the lower-left grid element. Default starting value is 1.
- Bounds Dataset: Defines the extent for grid creation, supporting point, line, and region datasets.
- Generates a mesh region that intersects the range dataset: Restricts output grid index dataset to areas intersecting with input Bounds Dataset. Requires Bounds Dataset specification.
When unchecked, generates regular grid based on specified rows/columns regardless of Bounds Dataset.
Subsequently, you may perform Calculate Adjacent Fields operations on the index grid.
Application Example
Using Sichuan Province as Bounds Dataset with 6 rows/columns (other parameters default). When Generates a mesh region that intersects the range dataset is checked, results shown in Figure 1.
When unchecked, generates 6*6 regular grid as shown in Figure 2.
