<h2>Sources for maps</h2>

<p>

All maps used in mapbuilder are from OGC

<a href="?page=reference#ogc">Web Map Context documents.</a>

A context document provides an interoperable way of storing and sharing

maps created using the various OGC web service specfications

</p>

<p>

Sources for these maps:

<ul>

  <li><span class="title">Create your own:</span>

  Use a text or XML editor to add and delete layers to an existing or new

  context document.

  This method is tedious and difficutl but can be used for simple changes.

  </li>

  <li><span class="title">owsview:</span>

  Currently, the best application for creating a context document is

  <a href="http://cgdi-dev.geoconnections.org/prototypes/owsview/index.html" target="GetContext">owsview.</a>

  Functions include adding layers by browsing WMS capabilities doc and loading

  and saving context documents.

  </li>

  <li><span class="title">Search the GeoConnections Discovery Portal:</span>

  The Discovery Portal offers a

  <a href="http://geodiscover.cgdi.ca/ceonetWeb/doc?dispatchServlet=/biz&servletName=bizServlet&service=searchForWebServiceData" target="GetContext">

  web service search</a> function which will

  dynamically generate a context document based on search parameters.

  The limitiations of this method are that it depends on the web service

  providing good metadata in the capabilities document and a slow response of the

  search engine.

  Look for improvments to this service as new registry technology is implemented.

  </li>

</ul>
