Okay, so yes, we are going to talk about geomafish, the status of the project, and also about vector ties, but much less technical stuff. Okay, I will quickly talk about the company and what we do, and a lot about geomafish
00:25
vector ties. It's a first implementation vector ties in geomafish, the big step of migrating geomafish to web components, and about Kubernetes support, and so project examples.
00:42
So welcome to camp. So we are open source service provider since 2001. We are bigger and bigger, more than 150 employees now. I was the sixth employee in 2006 when I joined the company.
01:03
So yeah, we are also contributors, not only service provider. We use a lot of agile software development, and we have experts in DevOps, et cetera. And yes, we are the largest European service provider for a geospatial open source.
01:25
Geomafish is a flexible web GIS. You can see here screenshots of the demo project. It's highly customizable. It's more like a framework than a product.
01:41
It's highly interoperable with all the standards using QGIS server or map server or the map provider. We have a desktop interface with a lot of features, a bit too many features for the
02:04
mobile. That's why you have a mobile interface too, and a very rich administration interface to be able to add layers, add themes, also manage all the holes in users, et cetera.
02:23
So Geomafish is a community-driven project. We have quite a large community of more than 20 members and a project steering committee. So I didn't tell that before, but you saw the map. We are in Switzerland, but also in France and in Germany.
02:45
Originally, Geomafish was more a Swiss project, but now we have also customers in France and in Austria, and maybe soon in Germany. I'm not sure. So community members are Swiss cantons, cities, but also in private sector.
03:07
And we are a member of this community as the editor of the solution. So the goals of the community is sustainable development, so promote dialogue between the members, decision-making, fair funding, and also the fact that we have
03:29
several members, so the contribution level can be lower. And this model works since 2011. So this is about Geomafish, what it is, and now let's see the new features of Geomafish.
03:46
We just released 2.7 release. So you know what is vector ties, of course, but for our customers, it was important to
04:01
have this support added to Geomafish because we have more and more services offering vector ties. The advantages, you know them, adapt to screen resolution, the custom size on the client side, light files, and also much faster to generate new set of data.
04:27
So the first implementation Geomafish, it was quite a small project, actually. The budget was not very big, so we had to choose and not do full support of vector
04:40
ties in the solution. But that was important for us to have this implementation, this first implementation at all levels. So from the data in the database to the visualization on the front end.
05:02
So screenshots, yes. We have here a map with vector ties. Actually, it is a partial implementation, so only base maps can be vector ties right now. We had to change the administration interface to be able to add this new type of layer.
05:27
So this is what you see here, a screenshot of the administration interface. Maybe a bit more technical is the architecture of how we did that.
05:42
So as I said, we changed the administration interface to be able to configure the SQL query that will be the way to extract data from the PostGIS database.
06:01
And also, we have a link to the style. The vector ties service in the middle here, for each request from the client, it will get the SQL query, add what it needs to be added to be able to get just one tile
06:27
in the database, and also get the style, of course. And this will give the vector tie that will be sent to the client.
06:41
And all this, of course, is done n-types when you have to display n vector ties. Okay, as I said, it was in partial implementation, and so what we did not do and that we would
07:02
like to do if we have the funding for that. And adding, of course, the standard layers, not only the background layers, adding the possibility to have the query on vector tile. It can be either from the vector ties itself, when you click on it, you have the information
07:25
that is into the vector tile, or using WFS as a fallback. We are also thinking about PDF print, because we have a quite powerful print module in geomapfish,
07:45
so it would be interesting to have the print also for vector ties. It can be on the server side, as it is now with mapfish print, what we use for non-vector ties, but it could be also done on the client, it's not fixed now.
08:08
We have some improvement to do with the style management, and on the client side rendering, right now we use open layers, but we could use something else, maybe to be able to have
08:22
maybe more powerful rendering on the client side. Okay, so the second big news about geomapfish is the fact that we are migrating to web components.
08:42
That was quite a challenge actually, because we are using right now AngularJS, and AngularJS is at the end of its life, and so we had to change it. So last year we had a big thinking with the whole community of geomapfish, how to get
09:02
rid of AngularJS, and so we had a big analysis, and we decided to go to web components using elite elements, so it's quite a light library, and one important goal was to have a smooth
09:22
migration, because for customers it's very important to be able to continue to use, to update, and to improve the framework, and to of course continue to update and improve their projects using the framework.
09:40
It was totally impossible to stop and to do the migration and then continue with the new version. So, we did some proof of concept that will be now followed by an iterative process to have at the end a non-AngularJS client, and also one important aspect also is that
10:12
all developments, including the proof of concept, are reusable. It was important from the beginning of the proof of concept that all developments were
10:24
reusable. It's not a proof of concept and then to the trash. So this is our roadmap for migrating geomapfish. So, the 2.7 is out, it was out like a couple of weeks ago, or maybe one month, and it's
10:50
stable, it's a long-term support version. It proved the concept, and also it includes all the breaks that are needed for continuing
11:05
this process of migration. Also, on our project aspect, it is important also to have better estimates, and so we did some migration of some components, and now we know more how long it takes to do every
11:27
component of the solution. Next year, we will have the 2.8 with more web components migrated, and the goal is to have in 2024 the version 3 of geomapfish without AngularJS.
11:54
Another evolution of the product is the fact that we are supporting more Kubernetes
12:01
environments. So, with the 2.6, it was possible to use OpenShift. The goal was to have a Swiss cloud provider because many of our customers want to be hosted in Switzerland, but we needed to have a wider range of providers, and so with the
12:26
2.7, we did what was needed to have the support of Microsoft Azure. Why Microsoft Azure? It's also because it is hosted in Switzerland, and AWS, it's not guaranteed.
12:50
Okay, a couple of examples of geomapfish implementations. Here we have the Carto-Lacote project.
13:00
It's a project of the municipality of Nyon next to the Lemon Lake, Lake of Geneva, and also other municipalities around. What is interesting here is that they have a lot of themes with a lot of layers inside
13:22
each of them, and so, yeah, they did a very good job also with the monetization. It looks good, and for the screenshot, I open also the fact that we have Street View module
13:44
in the geomapish. That is not new, but that was nice to have the castle of Nyon. Another project is a project at EPFL. It's the polytechnical school in Lausanne.
14:05
Until very recently, we had our office next to this school, so it's a historical customer. Now we are moving. This project is interesting on different aspects.
14:22
First, it's one of our projects that has the most customized interface. What you see on the left here is the interface of the public application for visitors, for students of the school, and this is highly customized.
14:44
This is not at all what looks the standard geomapish. And so, yeah, this is very interesting. They have also a routing module. Here we can see the line of the routing.
15:02
I don't have a screenshot here, but they have a second application for professionals, so it's not only, oh, yes, it's the next slide. Okay, I will tell you about that next slide. Here, below, it's possible to include a map in their website.
15:26
It was important for the school to have, for instance, here it's a restaurant, and this restaurant is located on this place, and so they have on the web page of the restaurant also an interactive map coming directly from geomapish.
15:43
And yes, the professional portal is here. So this is much more standard. This is the geomapish standard. They changed only some colors to be more EPFL-like colors. And I told you about the routing.
16:01
So they have a very powerful routing system, so they can say, okay, I want to go from my office to this restaurant, and there will be routing for pedestrians. And the editing of the graph is directly done in geomapish.
16:21
So this is a specific module that we developed for them. And what you can see here is the graph, and it's quite complex, but it works well. And finally, here's a screenshot of the demo application of geomapish.
16:45
What you can see here is the LIDAR profile. It was implemented first for the content of Neuchâtel, and now it is from the 2.7
17:03
version, it is in the heart of geomapish, and also it is one of the first components that we moved to web component technology. And I thank you for your attention.
17:20
And you have all the links here to the demo, and the second link is the website of the community, and then documentation, et cetera. Yeah, thank you.
