Overview of Adding Rasters and Surfaces
Concept Procedure Quick Reference

To add a raster image to the map

  1. In Display Manager, click DataConnect To Data.
  2. In the Data Connect window, select Add Raster Image or Surface Connection in the Data Connections By Provider list.

    If you are adding a WMS image, see Adding an Image from a WMS (Web Map Service). If you are adding an image whose format does not appear in the Data Connect window, see Using Other Raster Image Formats.

  3. Under Connection Name, type a name for this connection.

    You can give the connection any name you like. This name appears in Map Explorer as the name of the feature source.

  4. Click the folder icon to browse to the folder containing multiple images, or click the image icon to specify a single image.
  5. Click Connect.
  6. In the Add Data To Map area, select the images to include.

    If this source contains only a single image, that image is selected automatically. If it contains multiple images, you can right-click any of them and select Select All or Select None.

  7. For each image you select, make sure the Coordinate System and Vertical Units entries are correct.
    • Hold your cursor over an image name to see its native coordinate system. The Coordinate System entry should match this.
    • Scroll the table if necessary to see all the columns.
    • To change the coordinate system, click Edit Coordinate Systems and choose the appropriate coordinate system.
    • To change the vertical units, click the current entry to display a down arrow that lets you choose a different one.
  8. To combine all the images on one map layer, select Combine Into One Layer. This is useful for combining a series of images to create a single layer; for example, you can combine GeoTIFs of each county to create a state map.
  9. Click Add To Map.
  10. If prompted, specify the location, scale, and rotation for each image.

    Some image files contain placement information and are placed automatically in your map. For images that do not contain placement information, you are prompted for the location, scale, and insertion point.

  11. In Display Manager, make sure that the image layer is in the correct display order.

    You can move the raster layer below objects and features.

    • In Display Manager, click Groups Draw Order. (If this button is already labeled Draw Order, you can omit this step.)
    • Drag the raster layer down in the list. Layers at the bottom of the list appear behind the ones above them.
NoteYou must use a different process to insert an image whose format is not available in Data Connect, or to specify correlation information for an image whose file does not specify it.
