     764<Text id="images-gps-1">Create a new collection in GLI called <i>Images-GPS</i>. In the <b>Gather</b> panel, drag and drop the 4 folders in <Path>sample_files &rarr; images_gps</Path> from the file system view on the left into your collection view on the right.</Text>

     772<NumberedItem>
     773<Text id="images-gps-4">If you were to preview it at this stage, it would just be a simple image collection. However, as these images contain GPS metadata embedded into them, building the collection the first time would have extracted this. We can use this extracted location metadata to display the location data in these images more meaningfully. Move to the <b>Enrich</b> pane, expand a folder, select an image and scroll through its extracted metadata to find several pieces of metadata specifying Latitude and Longitude information: ex.LatShort, ex.Latitude, ex.LngShort and ex.Longitude.</Text>
     774</NumberedItem>
     775<NumberedItem>
     776<Text id="images-gps-5">First though, since the images are organised by folder, we can easily assign <i>folder-level</i> metadata to the images which will help with classifying them. Still in the <b>Enrich</b> tab, select the eiffel-tower folder, and in its <b>dc.Title</b> field type <i>Eiffel Tower</i>. Since this metadata is assigned at folder level, it is inherited as <b>dc.Title</b> metadata by all the images in the folder. Now select each of the remaining folders in turn, and assign the appropriate values for their <b>dc.Title</b>: <i>Musée d'Orsay</i>, <i>Parc de Luxembourg</i> and <i>Panthéon district</i>.</Text>

     779<Text id="images-gps-6">Shift over to the <b>Design</b> panel, select <b>Search Indexes</b> on the left and press the <b>New Index</b> button on the right. Scroll down to the ex.LatShort, ex.Latitude, ex.LngShort and ex.Longitude metadata and tick the boxes for all four and press <b>Add Index</b> to create an index on all these 4 pieces of metadata.</Text>

     781<NumberedItem>
     782<Text id="images-gps-7">Select <b>Browsing Classifiers</b> to the left of the <b>Design</b> tab. In the <b>select classifier to add</b> dropdown box, choose <b>AZCompactList</b> and press <b>Add Classifier</b>. In the configuration dialog that appears, set the metadata field to <b>dc.Title</b> to create a classifier that groups all images under Eiffel Tower into one bookshelf and similarly creates bookshelves for the other 3 categories.</Text>

     785<Text id="images-gps-8">Greenstone has a map view that can make use of this location metadata to present the images. To enable the map, move to the <b>Format</b> panel, select <b>Format Features</b> on the left, select the format statement for the <b>browse</b> classifier.

     792<Text id="images-gps-10">Since we've only made changes in the Format tab, we don't need to re-build the collection to see these changes in effect. Press the <b>Preview Collection</b> button and select the browsing classifier. The page that opens up shows a Google map, with the locations of the images in the collection pinpointed on it. The map view can also scroll through all the images, locating each place and associated image in turn.</Text>
