A graticule is the network of lines of latitude and longitude drawn at regular intervals on a map. Graticules are created in MAPublisher using the Grids and Graticules tool. In some maps, you may want to limit the area on the map that a graticule covers. For example, you may want it to cover only the map’s area of interest. The image below is a map of North America with a graticule drawn at 5-degree intervals. US State boundaries are drawn in white. In this post, we'll modify the graticule three times so it conforms to the edges of the image, so it covers only the Continental United States, and lastly a combination of the previous two modifications.
When georeferencing a map in Geographic Imager, there are two tools which can be used to check spatial accuracy: Validate and Show Image Extents Online. With Validate, click a point on the image and it will show the corresponding location on the web map service so that you can compare the difference between them. Show Image Extents Online will display a rectangle representing the spatial extent of the image on the web map.
If you launch Adobe Photoshop and then realize that extensions didn't load properly, including Geographic Imager, it may be due to a setting in Adobe Photoshop Preferences. Go to Edit > Preferences > Plug-Ins. Locate the ‘Load Extension Panels’ in the Filter and Extension Panels group. If it is unchecked, it prevents all extension panels from loading and the Window > Extensions menu is greyed out and prevents users from opening extension panels manually. When this preference is checked, the Geographic Imager panel will load on start-up.
