New versions of this module and support for Omeka S version 3.0 and above are available on GitLab, which seems to respect users and privacy better than the previous repository.
Cartography is a module for Omeka S that allows to annotate (to draw points, lines, polylines, polygons, etc.) an image or a map with the web annotation vocabulary and the web annotation data model.
Maps can be georeferenced (wms) or ungeoreferenced images, so it is possible to annotate any images, even non-cartographic ones.
This module requires the modules Annotate and Data Type Geometry. If the module Generic is used, it must be version greater or equal to 3.4.41.
The module uses external libraries, so use the release zip to install it, or use and init the source.
See general end user documentation for installing a module.
Download the last release Cartography.zip
from the list of releases (the
master does not contain the dependency), and uncompress it in the modules
directory.
If the module was installed from the source, rename the name of the folder of
the module to Cartography
, go to the root of the module, and run:
npm install
composer install --no-dev
gulp
See notes in the module Data Type Geometry.
The module allows to annotate standard images and georeferenced maps.
dcterms:spatial
, for example: https://mapwarper.net/maps/wms/12428
with
label London Hogenberg 1572
. There can be multiple wms layers, for example
you can add the Roads to Santiago de Compostela in Spain
too with the url
https://www.ign.es/wms-inspire/camino-santiago?layers=PS.ProtectedSite
.Then, simply open the item (the display view, not the edition view, because the
annotations are saved outside of the resource metadata), go to the tabs
Describe
or Locate
, then annotate.
There may be multiple images and georeferenced maps. Furthermore, the upper maps are displayed too: the item sets wms layers are displayed with the item one, and the item ones with the media one.
Notes
The images and the maps can be described with any metadata. These metadata are
listed in a standard Òmeka resource template, but it must have the class
oa:Annotation
.
The images and the maps can be described with any metadata. Nevertheless, it is
recommended to use standard annotations ones, in particular rdf:value
for the
body (equivalent to dcterms:description
for the resources) and oa:motivatedBy
for annotation itself (to simplify the search). The relations with other
resources (for example identification of an object on an image is an image of
another item) should use the element oa:hasBody
.
Note that according to the Web Annotation data model, an annotation is divided in three part: the annoation itself, one or more target (only one with this module) and zero or more bodies (a description, a link, etc.). So the properties of the annoations should be attached to one of this part via the resource template, so they will be saved regularly. It's particularly important for the non-standard metadata (the default one are automapped according to the data model, when possible). The default automapping is set in a config file of the module Annotate and can be updated.
There may be one or multiple forms for each tab (Describe and Locate), for example one to describe object, another one to identify people, and another one to describe place. They are selected in the main settings of Omeka S.
The annotations use the web annotation vocabulary.
The base maps of the tab "Locate" can be customized. Just set it as js in the config. For example, to include the French IGN map service with the default map, fill the text area with the code below.
/**
* Define the layer type:
* - GEOGRAPHICALGRIDSYSTEMS.MAPS
* - GEOGRAPHICALGRIDSYSTEMS.MAPS.SCAN-EXPRESS.CLASSIQUE
* - GEOGRAPHICALGRIDSYSTEMS.MAPS.SCAN-EXPRESS.STANDARD
*
* @url https://geoservices.ign.fr
*/
var layerIGNScanStd = 'GEOGRAPHICALGRIDSYSTEMS.MAPS.SCAN-EXPRESS.STANDARD';
// For test only. Get a free key for production on https://geoservices.ign.fr/blog/2018/09/06/acces_geoportail_sans_compte.html.
var ignKey = 'choisirgeoportail';
var url = 'https://wxs.ign.fr/' + ignKey + '/geoportail/wmts';
var ign = new L.TileLayer.WMTS(url, {
layer: layerIGNScanStd,
style: 'normal',
tilematrixSet: 'PM',
format: 'image/jpeg',
attribution: '© <a href="https://www.ign.fr">IGN</a>',
});
baseMaps = {
'Streets': L.tileLayer.provider('OpenStreetMap.Mapnik'),
'Satellite': L.tileLayer.provider('Esri.WorldImagery'),
'Terrain': L.tileLayer.provider('Esri.WorldShadedRelief'),
'IGN': ign,
};
Note: the key provided here for access to IGN services must be used for test purpose only. In production, you must register to get a free ign key.
A similar js can be added for images to describe, but is not managed directly by the module currently.
The geometries are saved as standard Omeka values and indexed in a specific table with a spatial index for quick search via the module Data Type Geometry.
Warning: The geometry "Circle" is not managed by WKT or by GeoJSON, but only
by the viewer. It is saved as a POINT
in the database, without radius.
According to the discussion on the working group of JSON-LD and GeoJSON, the
GeoJson cannot be used in all cases inside a JSON-LD. So the representation uses
the data type http://www.opengis.net/ont/geosparql#wktLiteral
of the [OGC standard].
The deprecated datatype http://geovocab.org/geometry#asWKT
is no more used.
{
"@value": "POINT (2.294497 48.858252)",
"@type": "http://www.opengis.net/ont/geosparql#wktLiteral"
}

It’s always recommended to backup your files and your databases and to check your archives regularly so you can roll back if needed.
