IONIC GeoViewer makes intensive use of OpenGIS/ISO Web Map Contexts. Please read the Concepts Guide, chapter 3 to learn more about contexts or consult www.opengis.org for the specification.
Saving the context means: serialize the current GeoViewer context into an XML file and
download it to your hard disk for future re-use. You can achieve that by using the
SaveContext widget designated by this icon:
. You will then need
to locally save the context XML file using the standard browser SaveAs dialog.
Loading a context means: replace the GeoViewer current context by a new one that will be reconstructed from a local XML file saved on your hard disk.
![]() | Since the new context will override the existing one, please ensure you first saved the current context before loading a new one. |
To load a local context into the GeoViewer, please click on this
icon. Click the
button and locate the XML file you want to load,
as shown by the following screenshot:
Using the SendContextByMail widget, you can email an XML context file to another user who will then be able to upload it in any IONIC client.
To send the current context, please click this icon
then fill up the
following form (recipients, subject and body) and click the button.
Recipients will receive a mail with two attachments: the context XML file and an image preview of the resulting map.
