Creating elevation points from DEMs

获得 Production Mapping 许可后可用。

The Create Elevation Point From DEM tool can add elevation points where you click on the map. The template used with the tool is the point layer that contains the elevation value field. This elevation value is automatically calculated from the raster when the point is created on the map.

The elevation values are usually stored in the ZV2 field but may be in a different field in the data you are using. You can specify the name of the field that stores the elevation values using the Contour Field Name Options tool.

注：

When you have a digital elevation model (DEM) or digital terrain elevation data (DTED) loaded in the map, the elevation values for the points are interpolated based on the point's position on the contour.

注：

If you have a .tif or similar file loaded in the map, the elevation values are based on the pixel values in the image.

1. 启动 ArcMap。
2. Load a raster in the table of contents.

   提示：

   You must have both a point and a raster layer loaded to perform this task.

3. 在主菜单上，单击自定义 > 工具条 > 生产编辑。
4. 在主菜单上，单击自定义 > 工具条 > 绘制生产等值线。
5. 单击生产编辑工具条上的启动生产编辑按钮 。

   注：

   使用启动生产编辑工具开始编辑会话时，系统将自动显示管理要素和创建属性、更新属性或元数据属性窗口。

   提示：

   如果开始编辑会话时未显示创建属性、更新属性或元数据属性窗口，请单击管理要素窗口上的显示/隐藏属性按钮 。

6. Click the Create tab on the Manage Features window.
7. Choose the template for the elevation points.

   This is typically named ElevP.

   提示：

   The point layer must contain a ZV2 or other elevation attribute, which can be viewed in the attribute table in the Create Attributes window.

8. Click the Create Elevation Point From DEM button on the Production Contouring Tools toolbar.
9. Hover over rasters in the map to view their heights in the lower-left corner of the status bar in ArcMap.
10. Click in the map to create a new elevation point.

    The point is selected in the map.

11. Save the edits when you are finished by clicking the Save Edits button on the Production Editing toolbar.
