Description: Define geographic data defined as Lines. Figure 235 shows an example of [Lines].
Geographic data group in which [Polyline] can be defined
[Polyline] can be added only to Geographic Data group [Reference Information].
[Polyline] on [River Cross-section Window]
On [River Cross-section Window], the intersection points between [Cross-section] and [Polyline] are displayed.
Using this function, you can add [Polyline] as reference information on [Pre-Processing Window] first, and you can edit the cross-section shape, considering the [Polylines] that corresponds to roads, for example.
Figure 236 shows an example of [Polyline] shown on [River Cross-section Windo].
Please refer to [Generate point cloud data] for the detail of [River Cross-section Window].
Drawing charts with calculation result interpolated on polylines
iRIC 1.0.14 and later can draw charts with calculation result interpolated on polylines. Please refer to [Graph Window] for detail.
[Lines Attribute Browser]¶
When [Lines] data is selected in the [Object Browser], [Lines Attribute Browser] is shown. Figure 237 shows an example of [Lines Attribute Browser]. The list of columns in [Lines Attribute Browser] is shown in Table 22.
|Name||The name of lines. You can edit the values.|
|Value||the valud of lines. You can edit the values.|
|Show||When clicked, the clicked line is shown in the center of the drawing area.|
For [Lines], user can select multiple lines at the same time. the selected lines can be deleted or sorted with one operation.
User can select line with the two ways below:
- Mouse operation: Draw boundary box by left-dragging, and all lines sorrounded by the box are selected.
- Attribute browser operation: Click on items in [Lines Attribute Browser], and the clicked item is selected. You can select multiple items, by clicking with pressing Ctrl key.
[Add New Polyline]¶
The procedure to add a new Polyline is as follows:
- Select the [Reference Information] under [Geographic Data] in [Object Browser] (Figure 238).
- The operation below adds a new Polyline to [Object Browser], and that Polyline is selected.
Menu bar: [Geographic Data] (E) –> [Polyline] (L) –> [Add New Lines]
- On the canvas, add vertices to the line by left clicking (Figure 239).
- Double click or press the Enter key to complete defining the Polyline.
[Add New Line]¶
Description: Adds a new line to [Lines] data.
[Add New Polyline] adds a new [Lines] data. On the other hand, this function add an new Line to the [Lines] data that already exists.
The steps to define a line is the same to [Add New Polyline].
[Edit Value] (V)¶
Description: Edits data value on the Line.
When you select [Edit Value], the [Edit Elevation value] dialog (Figure 240) will open. Input a new value and click on [OK].
[Add Vertex] (A)¶
Description: Adds a vertex to the [Polyline].
When you select [Add Vertex] and move the cursor to the edge of [Polyline], the cursor changes to that shown in Figure 241. 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 [Polyline].
When you select [Remove Vertex] and move the cursor onto the vertex you want to remove, the cursor changes to that shown in Figure 242. Left clicking will remove the vertex.
[Edit Coordinates] (C)¶
Description: Edits the coordinates of the vertices of the [Lines].
When you select [Edit Coordinates], the [Polyline Coordinates] dialog (Figure 243) will open. Edit the coordinates and click on [OK].
Description: Merge lines in other [Lines] to this data.
[Select data to merge] dialog (Figure 244) 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 245) is shown. Select the [Geographic Data] group to which you want to copy the data.
Then, [Copy Setting] dialog (Figure 246) is shown. Specify the values of the lines, and click on [OK] button, to finish copying the [Lines] data.
