Description: Sets the values of geographic data within the area of the Polygon. Figure 218 shows an example of the [Polygon].
[Polygons Attribute Browser]¶
When [Polygons] data is selected in the [Object Browser], [Polygons Attribute Browser] is shown. Figure 219 shows an example of [Polygons Attribute Browser]. The list of columns in [Polygons Attribute Browser] is shown in Table 20 .
|Name||The name of polygons. You can edit the values.|
|Value||the valud of polygons. You can edit the values.|
|Show||When clicked, the clicked polygon is shown in the center of the drawing area.|
For [Polygons], user can select multiple polygons at the same time. the selected polygons can be deleted or sorted with one operation.
User can select polygons with the two ways below:
- Mouse operation: Draw boundary box by left-dragging, and all polygons sorrounded by the box are selected.
- Attribute browser operation: Click on items in [Polygons Attribute Browser], and the clicked item is selected. You can select multiple items, by clicking with pressing Ctrl key.
[Add New Polygons]¶
The procedure to add a new [Polygons] is as follows:
- In [Object Browser] ,select the group of [Geographic data] to which you want to add [Polygons] data (Figure 220) Please note that the list of groups of [Geographic Data] differs depending on the solver you are using.
- Do the following operation. Then, a new [Polygons] data is added and selected in the object browser.
Menu bar: Geographic Data (E) –> Polygons (P) –> Add New Polygons
- In the drawing area, define the nodes of the polygon, by left-clicking. (Figure 221)
- Finish defining the shape of polygon, by double-clicking or pressing Enter key. Then the dialog to specify the value at the defined polygon is shown (Figure 222), so input the value and click on [OK]. Please note that the widget to edit value differs depending on the type of [Geographic Data].
[Add New Polygon]¶
Description: Adds a new Polygon to [Polygons] data.
[Add New Polygons] adds a new [Polygons] data. On the other hand, this function add an new Polygon to the [Polygons] data that already exists.
The steps to define a polygon is the same to [Add New Polygons].
[Edit Value] (V)¶
Description: Edits data value within the Polygon.
When you select [Edit Value], the [Edit Elevation value] dialog (Figure 223) will open. Input a new value and click on [OK].
[Add Vertex] (A)¶
Description: Adds a vertex to the [Polygon].
When you select [Add Vertex] and move the cursor to the edge of [Polygon], the cursor changes to that shown in Figure 224. Left click on the line and drag it to add a new vertex. The vertex is placed where you release the left button.
[Remove Vertex] (R)¶
Description: Deletes a vertex from the [Polygon].
When you select [Remove Vertex] and move the cursor onto the vertex you want to remove, the cursor changes to that shown in Figure 225. Left clicking will remove the vertex.
[Edit Coordinates] (C)¶
Description: Edits the coordinates of the vertices of the [Polygon].
When you select [Edit Coordinates], the [Polygon Coordinates] dialog (Figure 226) will open. Edit the coordinates and click on [OK].
[Add Hole Region] (H)¶
Description: Adds the Hole Region to the [Polygon].
[Delete Hole Region] (D)¶
Description: Deletes the Hole Region from the [Polygon].
Description: Merge polygons in other [Polygons] to this data.
[Select data to merge] dialog (Figure 231) is shown. Select the data to merge, and click on [OK] button.
Description: Copy the data to other [Geographic Data] group.
[Select Graographic Data] dialog (Figure 232) is shown. Select the [Geographic Data] group to which you want to copy the data.
Then, [Copy Setting] dialog (Figure 233) is shown. Specify the values of the polygons, and click on [OK] button, to finish copying the [Polygons] data.
