Map courtesy Puerto Rico Department of Transportation and Public Works, Highway and Transportation Authority. However, image data is one file, or layer, so you can not break down the different components and attach data to them separately. Image data is the best choice if you need to add a point of reference to vector data without attaching additional information.
Images can also be attributes of map features.
In other words, you can add images to other map features so that clicking on the feature would display the image. For example, you might have a map of California with cities. By clicking on the point that is the City of San Francisco, you open up an image of San Francisco. A satellite image can be used as a map or as an attribute of a map feature. Almost any document or photograph can be scanned and stored as an attribute in a GIS database.
