If you link your annotations to locations using the geotagging feature, those annotations can be automatically visualised on a map by selecting the map view in Recogito’s toolbar. In map view it is possible to select between the OSM (default) and the satellite map tiles. They both enable you to see the pins on the map at a very high zoom level. The default map visualisation in Recogito may help users to see more clearly where historical features in the map are now, and how their urban context has changed through the years.
But Recogito also has other visualisation options that may become useful with certain types of documents. These options can be accessed via the gear icon in the bottom left corner of the map view.
Visualising by tag:
If you have used tags to enrich your annotations, you can select this option. Annotations that share the same tag will be shown in the same colour, and a small legend with all colours and corresponding labels will appear on the left. If the annotation has more than one tag, only the first one will be considered for the purpose of this visualisation.
So, if you are interested in highlighting, for example, all religious monuments, or all places related to railway stations that have been annotated, bear in mind what is the tag that you are entering first. If you change your mind about tags order, you can always drag them around to be re-positioned.
Visualising by part:
As mentioned in the section on uploading images, when multiple files are uploaded at the same time they become bundled together in a “metadocument”. Users can annotate each file separately, but all annotations are represented together in the map view. This can enable some interesting comparisons, especially when, selecting the visualisation option “by part” is possible to assign a different colour to each provenance file. This option is currently only valid for images uploaded as files (in jpg, tiff or png format), and cannot be used for maps in IIIF or WMTS.
Color by category
In the document view, the one in which you perform your annotations, the default mode shows the annotations colour-coded by category. As explained in the section about the annotation interface, users can assign categories to the annotations, and each category is associated with a colour: red for entities, blue for labels, and green for symbols. Annotations with no category or with more than one category will show in black.
