GeoSpatial data over the Web GeoSpatial data over the Web

GeoSpatial data Web

A common problem today is to bring geospatial data

  • ver the web.

This has been solved already in the past; we won't bore you with that.

Need : access control Need : access control

?

But what about access control ? What if you want to bring your data over to the web, but not to everyone?

slide-37

Sample : GMap Sample : GMap

The easiest way to demonstrate the need is with an example. Here's the Gmap demo. Let's apply some access control to it.

Several single applications Several single applications

Without an access control tool, you would have to create several individual applications and apply security to each one.

Several applications to maintain is counterproductive.

Our solution : GeoPrisma A web mapping application featuring access control to geospatial data and dynamic user interfaces.

Now let's take a closer look at it. There are 2 main features to GeoPrisma: a proxy and a dynamic UI. But first let's present Geoprisma.

Built on OpenSource libraries

OpenLayers OpenLayers MapFish MapFish GeoExt GeoExt ExtJS ExtJS FeatureServer FeatureServer MapServer MapServer TileCache TileCache etc. etc.

First of all, GeoPrisma does not reinvent the wheel. We use existing and proven Open Source components such as OpenLayers, MapServer, MapFish and others...

Under the hood Under the hood

WMS WMS WPS WPS FeatureServer FeatureServer TileCache TileCache

Scribble

MapFishServer MapFishServer

Under the hood the concept is quite simple. Access control on the data is configured in an XML file. Multiple services can be defined, WMS, FeatureServer, TileCache and soon MapFishServer or WPS. All those services can serve the same layer. In GeoPrisma we regroup all those services under a component we call resource. And it's on the resource that we apply access control.

To illustrate what we are saying, here's a typical web mapping architecture, composed of a client browser running JavaScript applications (like OpenLayers) connecting with services on a server (WMS, WFS, TileCache).

GeoPrisma provides an access control layer that fits in between the client and the services.

GetMap request GetMap request Response Users GeoPrisma (Proxy) GeoSpatial services UI

Here's a simple example. When a user tries to connect to a WMS service, GeoPrisma checks if she has access to it and sends the request to the server to get a map If the user doesn't have access then the request is denied

Proxy Proxy

Authentication Access control list Data filtering

Components

You may ask yourself: what.s so special with GeoPrisma? I can do that in PHP or Python or whatever. Sure, but our proxy can integrate with any authentication library and connect to any geospatial service.

Integration with any authentication libraries

We currently have drivers to use LDAP, JOSSO, PostgreSQL DB, XML files for authentication. And it's easy to make more : extend a PHP class !

GeoPrisma can also connect to external applications. We already did it with GeoNetwork and with an application you can see in the presentation at 11:30 in Parkside G04.

The second big strength of GeoPrisma is its user interface generation capabilities. In a GeoPrisma application, the UI is always automatically generated based on the user permissions. That means that GeoPrisma generates a user interface based on specific user access. The tools can be „secured”.

Dynamic User Interface Dynamic User Interface

Custom UI templates

The UI is generated using a templating system, currently XSLT. The same application can have a different look for different clients or users.

Even a non roman language ! Well, that's more a mixture of characters, but it shows right-to-left language support. BTW, the maps you just saw are from a real world application using GeoPrisma deployed at the end of the summer.

Dynamic User Interface Dynamic User Interface

Widgets automatically added if access granted

But let's come back to one of the main reasons you want to use GeoPrisma: the automatically generated user interface. The tools (also known as widgets) in your application will be included only if you have the right access to the data they operate on.

Widgets automatically added if access granted

It's true for all the elements in the interface : the layers in the map and the legend of course But also for more specific tools like the query button

  • r the online editing features.

Dynamic User Interface Dynamic User Interface

Built with OpenLayers, MapFish, GeoExt, ExtJS, etc.

There's a nice library of widgets already included and it's growing fast. Most of them are simply the tools from OpenLayers, MapFish and GeoExt. That's one of the key ingredients of GeoPrisma : We don't reinvent the wheel When something is already available, we reuse it. If it's not, we do it and contribute it back to the right

  • project. We try to not have any custom tools in our

system.

Let's see GeoPrisma in pseudo-action (a 20-minute presentation doesn't allow for a live demo ;-) ) There will be 5 users with different access. Some will have read-only access and some will have read and write.

slide-60
SLIDE 60

27

This first user, the secretary, has read-only access to most features. The basic tools are included.

slide-61
SLIDE 61

28

Now if we look at the gardener, you can immediately see that with less access there are fewer layers available, but also fewer tools. Note how the gardener has the 'i' button working

  • nly for the parks. The roads are not there anymore.
slide-62
SLIDE 62

29

The civil engineer now, has write access to the roads, so there are new tools in the application. Notice the editing tools and the layer tree that now contains new layers.

slide-63
SLIDE 63

30

The settler can edit the cities as we can see. It's important to note that as the UI is built with limited tools, the transaction on the server is also secured to make sure that the queries are not hacked.

There are three contributors right now. The project was an initiative from Boreal-IS and was developed with the help of Mapgears. Nippour Geomatik joined later on and used GeoPrisma to build a mapping portal.

Boreal-IS contributed the code from GeoPrisma and it's now an Open Source project (BSD licenced). Simply go to geoprisma.org to get more information and download the zip on a web directory for a test drive. This presentation is actually part of the official launch

  • f the project. The same presentation is also given at

around the same time in Montreal, Canada. On the

  • ther side of the planet. That's geo-diversity! :-)
