The History of Open Geospatial

7 von 38
The Roots of Open Standards
More details and links can be found on the OSGeo Wiki .

8 von 38
M.O.S.S.
The need for Open Standards was the result of working with
pioneering software development in the geospatial realm.
1978: Development of M.O.S.S.
Solomon Katz
Dr. Carl Reed
...and many more

9 von 38
GRASS
1982: The Geographical Resources Analysis Support System project
is started - and development is ongoing to the day!

10 von 38
ETL
The real issue for both groups are not implementing the
algorithms but ETL'ing the plethora of proprietary data formats.
Extracting, transforming and loading the data causes the pains.

11 von 38
The Open Geospatial ...
1994: As a result a group of enthusiast start the
Open Geospatial Foundation.
1995: renamed into the Open Geospatial Consortium ( OGC)
as we know it today to accommodate the needs of the
industry, at that time mostly proprietary vendors.

12 von 38
M.O.S.S. and GRASS almost Die
In the wake of the standards efforts work on M.O.S.S. and
GRASS come to a standstill.

13 von 38
GRASS revived
Thanks to Markus Neteler GRASS is resurrected in 1998 after
freely floating on the Internet in deep freeze for a while.
It is still active to this day.

14 von 38
My private, little Open Source story
1998 Foundation of CCGIS as a one-man-show
Start of the development of Internet Map Servers.
Making business by implementing specific GIS applications.
2002: The German cadastral software SICAD is sold to AED,
which was previously acquired by ESRI.
As a result ESRI takes over the German cadastre.
Suddenly SICAD partners are ESRI partners?!?
Implementation cost using ArcObjects not viable.
Looking for alternatives (Intergraph, Autodesk, MapInfo, etc.).
The solution: MapServer running on FreeBSD (a free UNIX),
later PostGIS, etc.
2003: Consequently our geoportal software Mapbender is
released as Free Software.
2005: Wikipedia meets in Frankfurt, first interest in maps.
15 von 38
Open Geospatial Foundation
2005: Autodesk secretly decides to launch their GIS software as
Open Source piggybacking on MapServer. The community is
aghast! How can they dare? A big, fat, long discussion ensues.
Who owns this Open Source Software?
What's in a name?
What does good Open Source practice really mean?
How much "control" does a software development team
need?
Java/C++: Who is Friend who is Foe?
Can there be more than one Best Ever software?
...

16 von 38
OSGeo
After thoroughly debating and answering these important
questions the Open Source Geospatial Foundation
is born in February 2006:
Global
Inclusive
Do-ocratic
Truly Open
It is an umbrella organization of initially eight Open Source
software projects including GRASS. Everybody is happy.

17 von 38
The Internet
Meanwhile the Internet has become a viable option for distributed
computing.
Google shows that maps work on the Web.
There are Open albeit independent answers:
OpenLayers - software
OpenStreetMap - data

18 von 38
Open Data

19 von 38
Schuyler Erle
Your software is great. But it is worth nothing - without Data!

20 von 38
Read all the details about Open Data - Taming the Beast .

21 von 38
22 von 38
23 von 38
Learning Open Data Friendship
“ Open Data Friendship, also referred to as Beast
Control or Beast Trick, is the Force ability to
control data. Once calmed, the data can be used
by the Force user in various ways, including as a
service or INSPIRE beast. ”
Inspired by Star Wars , adopted for Data Wars

24 von 38
Where are we with Open Data?
Just across the chasm - or maybe not quite yet.

25 von 38
Public & Government Data
Data collected by the government shall be:
Freely accessible
Unencumbered by legal restrictions
Open for private and commercial use
The collection, maintenance and provision is funded by the
public. Therefore It is a public good.

26 von 38
Community Driven Data
Often volunteer driven Ad-Hoc collections of data.
Spatial data is collected and maintained by a crowd.
It shall be clearly licensed (but often is not).
Anybody can use, modify and redistribute.
Derived products (for example maps) may be copyrighted.
The data stays open and publicly avaialable.
Nota bene: According to Wikipedia the term crowdsourcing is nowadays used in a different context.

27 von 38
How does it all tie together?

28 von 38
OpenStreetMap has an API

29 von 38
But OpenStreetMap also has Data!
Usage of the data is regulated by the ODbL license:
Use of the data is free and open for anybody
Use of the map service is gratis (but limited)
Setting up your own servers is encouraged
The source of derivative works must be made available on
request (see licensing)

30 von 38
Ordnance Survey Great Britain OpenSpace
(API)

31 von 38
OpenStreetMap, Ordnance Survey, ++
So why not download all of this great data...
VectorMap District(r) from Ordnance Survey Great Britain
Ways, footpaths, rivernames, pubs from OpenStreetMap
Rights of way from municipalities
Designated offroad bicycle tracks
The hills database
...plus many more sources...

32 von 38
...overlay and individually style them on an Open Source
software stack (PostGIS, MapServer, Mapbender)...

33 von 38
...and print the result on fabric: SplashMaps - For the REAL
outdoors!

34 von 38
35 von 38
FreeGIS
Paolo Viskanic from R3 GIS has a similar story to tell. In
cooperation with TIS and other interested parties this lead to
the foundation of the project FreeGIS.net which is based on:
MapServer
PostGIS
GisClient
FreeGIS.net Viewer
PyWPS
OpenLayers
Feel free to join us in the afternoon for a workshop showing how
the project includes all aspects of Openness to implement
INSPIRE.
36 von 38
Summary
Geospatial Openness come in three complementing tastes:
Open Standards
Open Source Software
Open Data

They all have come to stay

  • 6. GIS Evolution Client/Server, Lightweight applications, Clouds, Crowds SDI (Spatial Data Infrastructure) Point clouds (Lidar) 3D+ AR Crowd Sourcing 6 von 38
  • 7. The History of Open Geospatial 7 von 38
  • 8. The Roots of Open Standards More details and links can be found on the OSGeo Wiki . 8 von 38
  • 9. M.O.S.S. The need for Open Standards was the result of working with pioneering software development in the geospatial realm. 1978: Development of M.O.S.S. Solomon Katz Dr. Carl Reed ...and many more 9 von 38
  • 10. GRASS 1982: The Geographical Resources Analysis Support System project is started - and development is ongoing to the day! 10 von 38
  • 11. ETL The real issue for both groups are not implementing the algorithms but ETL'ing the plethora of proprietary data formats. Extracting, transforming and loading the data causes the pains. 11 von 38
  • 12. The Open Geospatial ... 1994: As a result a group of enthusiast start the Open Geospatial Foundation. 1995: renamed into the Open Geospatial Consortium ( OGC) as we know it today to accommodate the needs of the industry, at that time mostly proprietary vendors. 12 von 38
  • 13. M.O.S.S. and GRASS almost Die In the wake of the standards efforts work on M.O.S.S. and GRASS come to a standstill. 13 von 38
  • 14. GRASS revived Thanks to Markus Neteler GRASS is resurrected in 1998 after freely floating on the Internet in deep freeze for a while. It is still active to this day. 14 von 38
  • 15. My private, little Open Source story 1998 Foundation of CCGIS as a one-man-show Start of the development of Internet Map Servers. Making business by implementing specific GIS applications. 2002: The German cadastral software SICAD is sold to AED, which was previously acquired by ESRI. As a result ESRI takes over the German cadastre. Suddenly SICAD partners are ESRI partners?!? Implementation cost using ArcObjects not viable. Looking for alternatives (Intergraph, Autodesk, MapInfo, etc.). The solution: MapServer running on FreeBSD (a free UNIX), later PostGIS, etc. 2003: Consequently our geoportal software Mapbender is released as Free Software. 2005: Wikipedia meets in Frankfurt, first interest in maps. 15 von 38
  • 16. Open Geospatial Foundation 2005: Autodesk secretly decides to launch their GIS software as Open Source piggybacking on MapServer. The community is aghast! How can they dare? A big, fat, long discussion ensues. Who owns this Open Source Software? What's in a name? What does good Open Source practice really mean? How much "control" does a software development team need? Java/C++: Who is Friend who is Foe? Can there be more than one Best Ever software? ... 16 von 38
  • 17. OSGeo After thoroughly debating and answering these important questions the Open Source Geospatial Foundation is born in February 2006: Global Inclusive Do-ocratic Truly Open It is an umbrella organization of initially eight Open Source software projects including GRASS. Everybody is happy. 17 von 38
  • 18. The Internet Meanwhile the Internet has become a viable option for distributed computing. Google shows that maps work on the Web. There are Open albeit independent answers: OpenLayers - software OpenStreetMap - data 18 von 38
  • 20. Schuyler Erle Your software is great. But it is worth nothing - without Data! 20 von 38
  • 21. Read all the details about Open Data - Taming the Beast . 21 von 38
  • 24. Learning Open Data Friendship “ Open Data Friendship, also referred to as Beast Control or Beast Trick, is the Force ability to control data. Once calmed, the data can be used by the Force user in various ways, including as a service or INSPIRE beast. ” Inspired by Star Wars , adopted for Data Wars 24 von 38
  • 25. Where are we with Open Data? Just across the chasm - or maybe not quite yet. 25 von 38
  • 26. Public & Government Data Data collected by the government shall be: Freely accessible Unencumbered by legal restrictions Open for private and commercial use The collection, maintenance and provision is funded by the public. Therefore It is a public good. 26 von 38
  • 27. Community Driven Data Often volunteer driven Ad-Hoc collections of data. Spatial data is collected and maintained by a crowd. It shall be clearly licensed (but often is not). Anybody can use, modify and redistribute. Derived products (for example maps) may be copyrighted. The data stays open and publicly avaialable. Nota bene: According to Wikipedia the term crowdsourcing is nowadays used in a different context. 27 von 38
  • 28. How does it all tie together? 28 von 38
  • 29. OpenStreetMap has an API 29 von 38
  • 30. But OpenStreetMap also has Data! Usage of the data is regulated by the ODbL license: Use of the data is free and open for anybody Use of the map service is gratis (but limited) Setting up your own servers is encouraged The source of derivative works must be made available on request (see licensing) 30 von 38
  • 31. Ordnance Survey Great Britain OpenSpace (API) 31 von 38
  • 32. OpenStreetMap, Ordnance Survey, ++ So why not download all of this great data... VectorMap District(r) from Ordnance Survey Great Britain Ways, footpaths, rivernames, pubs from OpenStreetMap Rights of way from municipalities Designated offroad bicycle tracks The hills database ...plus many more sources... 32 von 38
  • 33. ...overlay and individually style them on an Open Source software stack (PostGIS, MapServer, Mapbender)... 33 von 38
  • 34. ...and print the result on fabric: SplashMaps - For the REAL outdoors! 34 von 38
  • 36. FreeGIS Paolo Viskanic from R3 GIS has a similar story to tell. In cooperation with TIS and other interested parties this lead to the foundation of the project FreeGIS.net which is based on: MapServer PostGIS GisClient FreeGIS.net Viewer PyWPS OpenLayers Feel free to join us in the afternoon for a workshop showing how the project includes all aspects of Openness to implement INSPIRE. 36 von 38
  • 37. Summary Geospatial Openness come in three complementing tastes: Open Standards Open Source Software Open Data They all have come to stay 37 von 38
