50000 services milestone achieved

Spationeo Service map statistics

Spatineo monitoring agent network sends each publicly available Spatial Web Service a lightweight test request every 5 minutes. In total over 7 million availability measurements are collected daily. The same data stream is also used to drive the near real-time Quality of Service reporting and alerting system of Spatineo Monitor. The monthly service availability figures are aggregated from all successful and failed test requests for each country and their first-order administrative areas.

As we have collected these open data samples from 2012 onwards, we finally reached the 50 000 services milestone! On average we gathered 27.4 new services each day and during almost exactly five years we have been able to discover all existing and new open spatial web services.

The ones we have discovered are open-data sources, so when considering these numbers you have to keep it in your mind that these open-data services are only a part of the spatial data out there. Some services are hidden or disabled from the public.

First and 50 000th service

As we started to gather services to our monitoring list, the first open-data source we found was Kartta.Suomi.fi. It had 12 layers at that time and was typed as Web Map Service (WMS). This address was found on the 10th of April 2012.

Five years later, as we had discovered approximately 10 000 services per year, we discovered the 50 000th service! That honor belongs to Destatis, Homepage of the Federal Statistical Office of Germany. It’s a funny coincide that the 50 000th service was found in Germany, as they are hosting this year’s INSPIRE Conference! On the 11th of April, we discovered over 300 services from Destasis.

Facts and numbers

Within the 50 000 services we are monitoring, there are some reoccurring numbers to be seen. Out of all the services monitored, over 25% of them have 2 data layers. The biggest number of data layers can be found on the WorldMap of Harvard University, over 23 000 layers.

WMS or WFS?

When inspecting what type of services we have collected to our database, we discovered that there are couple of dominating types.

Spatineo servicemap type of services

So far, the most common service type is WMS. This is the standard of the industry but when we reach the milestone of 100 000 services, can the situation be different? The other dominant type was Web Feature Service (WFS). It has the second largest cut with 27% of the services we monitor.

Differences between countries?

Some countries have more public spatial data than others. Most common country domains on our list were the ones below, with following (approximate) number of services each:

  1. 1. Germany 12 000
  2. 2. France 6 000
  3. 3. Spain 3 000
  4. 4. Italy 2 500
  5. 5. Belgium 2 000

Apart from obvious country domains, there were several services with .edu and .net domains and if counting these accordingly, the Unites States would be ranked second, tieing with France, with about 6 000 services.

Availability of the services

Current availability of services in different countries and their administrative areas can be checked from Spatineo Service Map. It gives up-to-date data on both availability and services as well trends over the previous years.
More detailed information for each service can be viewed from Spatineo Directory.

Geospatial Information for Future Societies

Spatineo attended the Swedish Kartdagar (Map Days) conference that was held at the end of March in a beautiful city of Örebro. Topics such as Open data, Geospatial Information and Smart Building were discussed both in the presentations and on the exhibition.

Distribution of Geospatial Information

Anders Skog from Swedish Standards Institute asked in his presentation whether WMS is the right way to distribute geospatial information? Web maps must be easy to read, even when they are created by integrating data from several different WMS services.  How to harmonize the visualisation of a web map?. His recommendation was to use SLD (Styled Layer Descriptor) enabled WMS. A project between the national mapping and cadastral agency Lantmäteriet, Swedish Transport Administration, the Swedish Armed Forces, Swedish Maritime Administration, Geological Survey of Sweden, City of Malmö and Stockholm County Council is going on to develop basic cartographic guidelines of co-presentation of geospatial data. Anders Skog also emphasized the demand of availability and stability of Web Map Services when national web maps are based on them.

Benefits of Open Data

Katrin Falk from Lantmäteriet and Birgitta Olson from Swedish Environmental Protection Agency asked from the audience why they are not using spatial web services. A lot of spatial web services exist and they provide easy access to open geospatial data. Where are the innovations? Intelligent transportation systems and services are based on fluent flow of information between actors. The company HERE and the transport agencies from Sweden, Finland and Norway are testing a continuous flow of data from the road authorities to a map provider and to people who are using the data in different applications. How the standardized format and way how the data is delivered enable almost real time experience for the users. David Boman presented statistics how the use of open data of Lantmäteriet has increased and what benefits the users of open data have achieved. Improved efficiency, better quality and better information for decision making are the most important benefits.

Smart Building

Elisabet Argus from Bonacordi AB and Allan Almqvist from city of Malmö gave an impressive presentation about Smart Built Environment. One of the strategic innovation programs in Sweden is Smart Built Environment. The whole process from master planning to real estate formation, building information modelling (BIM), building permission, building and maintenance should be based on 3D information so that all information can be integrated and are accessible to all actors.   The goal is to decrease the negative impacts of new construction and renovation on environment by 40%, decrease the time from planning to a ready made project by 33% as well as decrease the building costs by 33%.
