Layout Map Grid Settings.

A Map Grid is a network of evenly spaced horizontal and vertical lines used to identify locations on a Map. Longitude and latitude network and kilometer network are provided. Longitude and latitude network is used to represent the GCS of the map by describing the latitude and longitude grid on the map. Kilometer network is a horizontal and vertical line with uniform spacing, which is used to describe the Projected Coordinate of the map.

The same map supports the addition of multiple grids. Maps in different coordinate systems support different Map Grid types. The details are as follows:

  • Geographic Coordinate System Map: support the addition of longitude and latitude network and kilometer network;
  • Projected Coordinate System map: support the addition of longitude and latitude network and kilometer network;
  • Planar Coordinate System Map: support the addition of kilometer network, but not longitude and latitude network.
Multiple Map Grid

Application scenario

  • When producing maps, according to the mapping specifications and requirements, set up grid, coordinate marking, Map Border and other elements for maps, and produce map products that meet the requirements.
  • When Map Bounds span multiple UTM zones, it is necessary to identify the coordinates of the corresponding UTM zones through multiple grids. It is possible to create multiple kilometer networks of different zone coordinate systems for the map, so that the Position Info marked in different zone areas is more accurate.

Create a grid

Support Create from TemplateMap Grid and provide two methods based on Predefined Templates and Template File:

  • Predefined Templates: Map Grid can be created based on template style and grid Parameters.

    Function Entry:

    • Object Operation tab-& gt Object Drawing group-& gt Grid;
    • Layout Map Properties panel- Add
      • button on the Map Grid toolbar;

    Map GridParameter Settings：

    • Grid Type: set the grid type as longitude and latitude grid or kilometer grid.
    • Coordinate System: if the grid type is kilometer network, the coordinate system of the kilometer network can be set as Projected Coordinate System; if the grid type is longitude and latitude network, the grid is the Geographic Coordinate System of the map by default, and modification is not supported.
    • Horizontal spacing: Used to adjust the distance between two adjacent horizontal grid lines. When the grid type is a longitude-latitude grid, the unit of interval is degree; when the grid type is a kilometer grid, the unit of interval is meter.
    • Vertical Interval: used to adjust the distance between two adjacent vertical grid lines. When the grid type is a longitude-latitude grid, the unit of interval is degree; when the grid type is a kilometer grid, the unit of interval is meter.
    • Number of rows/columns: The number of rows and columns of the grid can be calculated dynamically according to the set horizontal/vertical interval. By default, the map is divided into 10 rows and 10 columns. After the number of rows and columns is modified, the grid interval will also change dynamically.
    Caution:
    When

    making Map Grid, it will generate Map Grid according to the horizontal and vertical spacing. With the change of Map Bounds, the spacing of the grid will remain unchanged, and the number of rows and columns will change with the change of the range. It is recommended that after determining the Visible Bounds of the map in the layout, Generate a Map Grid.

  • Template File: In the Map Grid Tool column of the Layout Map Properties panel, click the Import button, and select the grid Template File (*.xml) in the pop-up Select dialog box. Map Grid is created based on the grid Template File.

  • Move Up/Move Down: When there are multiple Map Grids, the Display Order of Map Grid can be adjusted.
  • Delete: It is used to delete the grid selected in the list. It cannot be restored after deletion.
  • Visibility: can be used to set whether the grid is displayed.
  • Rename: After selecting the specified grid in the list, double-click the name cell to modify the name of Map Grid.
  • Grid Style: Click the grid style cell to set the outline style, grid type, grid style, Primary, Secondary, and the number of Secondary. The details are as follows:
    • Outline Style: Click the button to set the outline style of the grid in the Online Symbol selector. For details, see the Line Symbol Style Settings page.
    • Grid Type: Click the Drop-down Button on the right to set the Display Type of Map Grid line, which supports three types: solid line, cross hair and no grid.

    • Grid Style: When the grid type is solid line or cross hair, click the button on the right of the Grid Label, and set the Line Style of Map Grid in the pop-up Line Symbol Selector "dialog box to select the grid line type. And support adjustment of line width and line color.
    • Primary: Primary refers to the dividing line displayed on the Map Border at the intersection of each crisscross grid line and the map outline. The Primary check box is used to set whether or not to Show Major Division in the layout. Click the button to the right of the label control to set the line type, line weight, and color of the Primary in the pop-up Line Symbol Selector "dialog box.
    • Secondary: Secondary refers to the scale mark displayed on Map Border by dividing the distance between two adjacent Primary into several equal parts according to the number set in "Number of Secondary". As shown in the figure below, when the number of Secondary is set to 5, two adjacent Primary will be divided into 6 equal parts, and 5 Secondary will be displayed between two adjacent Primary. When Grid Type is set to Public, the Secondary check box is used to set whether Secondary is displayed in the layout. Click the button to the right of the label control to set the line type, line weight, and color of Secondary in the pop-up Line Symbol Selector "dialog box. Note: Only the kilometer network supports setting Secondary.

  • Label Style: The label is used to display the coordinates of the main scale mark. The longitude and latitude grid represents the longitude and latitude coordinates, and the kilometer grid represents the X and Y axis coordinates. Click the Label Style cell to set the label style in the pop-up dialog box. The contents that can be set are as follows:
    • Surrounded Label: Label the corresponding coordinates at the Primary around the grid. If the Surrounded Label check box is checked, the coordinates of the Display Grid will be displayed around the map frame; if the Surrounded Label check box is not checked, the label will not be displayed. The related Parameter Description of Surrounded Label is as follows:
      • Horizontal Position: It is used to adjust the position relationship between the annotations on the upper and lower sides of the map frame and the Primary. Three methods are provided: Middle, Left, and Right.
        • Middle: indicates that the label center point is aligned with the Primary center point;
        • Left: indicates that the label is located to the left of the main tick mark;
        • Right: indicates that the label is on the right side of the main tick mark;

      • Vertical Position: It is used to adjust the position relationship between the left and right sides of the map frame and the Primary. Three methods are provided: Middle, Top and Bottom.

      • Offset: mark the distance deviating from the map frame with and, unit: 0.1mm.
      • Vertical display: It is used to set whether the upper, lower, left and right dimensions are displayed in the vertical direction.

      • Visible: It is used to set the visibility of the upper, lower, left and right dimensions. If it is checked, it means that the dimension is visible; if it is not checked, it means that the dimension in the specified direction is hidden.
    • Corner Label:: Label the coordinates of the point at the corner of the rectangular map box. If the Corner Label: check box is checked, the coordinates of the corner of the rectangular map box will be displayed; if the check box is not checked, the label will not be displayed. Related Parameter Description of Corner Label: is as follows:
      • Horizontal axis offset: It is used to set the offset of the horizontal coordinate marking from the map frame in the horizontal direction, and the unit is 0.1mm;
      • Vertical axis offset: It is used to set the offset of the map frame in the vertical direction marked by the vertical coordinate, and the unit is 0.1mm;

      • Label Position: used to set Corner Label: and Display Method of Extension Line, with two methods of On Extension Line and Outside Extension Line:
        • On Extension Line: indicates that Corner Label is displayed on the extension line of the grid border, and the center of the dimension is on
          • the On Extension Line;
        • Outside Extension Line: indicates that Corner Label: is displayed on one side of the grid line.
    • Display Method: provides two Display Methods: Degrees, Minutes and Seconds and Degrees. When the map does not require high accuracy of longitude and latitude, or the longitude and latitude network is relatively dense, the available Display Method makes the map simpler. Applies to warp and weft webs only.
    • Dimension Digits Setting: When Map Scale is large, the first few digits of the grid dimension are the same, and only the last few digits are changed, you can adjust the dimension display digits to make the dimension more concise. There are two ways to set integer digits and decimal digits. It is applicable to the kilometer network, and it is not recommended to set the longitude and latitude network.
      • Integer Digits: Set the display digits of the integer part of the grid label, and calculate the digits from the unit digit. For example, if the kilometer grid label is 243547, and the integer digits are set to 4, then only the last 4 integers will be displayed, that is, 3547.
      • Decimal digits: set the number of decimal digits displayed in the grid dimension, i.e., the number of digits after the decimal point. For example, if the dimension is 3698.1826 and the number of decimal digits is set to 2, the dimension will be displayed as 3698.18.
    • Other Text Settings: The setting of other parameters such as the font, size, color, and Display Effects of the annotation is consistent with that of the normal text. For details, please refer to the Text Info page.
