Creating elevation points from DEMs

Disponible con licencia de Production Mapping.

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.

Nota:

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.

Nota:

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. Inicie ArcMap.
2. Load a raster in the table of contents.

   Sugerencia:

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

3. En el menú principal, haga clic en Personalizar > Barras de herramientas > Edición de producción.
4. En el menú principal, haga clic en Personalizar > Barras de herramientas > Perfil de producción.
5. Haga clic en el botón Iniciar edición de producción en la barra de herramientas Edición de producción.

   Nota:

   Las ventanas Administrar entidades, Crear atributos, Actualizar atributos o Atributos de metadatos aparecen automáticamente al iniciar la sesión de edición con la herramienta Iniciar edición de producción.

   Sugerencia:

   Si las ventanas Crear atributos, Actualizar atributos o Atributos de metadatos no aparecen al iniciar la sesión de edición, haga clic en el botón Mostrar/ocultar atributos de la ventana Administrar entidades.

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

   This is typically named ElevP.

   Sugerencia:

   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.
