M.O.S.S.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.

is started - and development is ongoing to the day!

ETLETLThe 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.

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

M.O.S.S. and GRASS almost DieM.O.S.S. and GRASS almost DieIn the wake of the standards efforts work on M.O.S.S. and

GRASS come to a standstill.

freely floating on the Internet in deep freeze for a while.It is still active to this day.

My private, little Open Source storyMy private, little Open Source story1998 Foundation of as a one-man-showStart 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: running on (a free UNIX),later , etc.2003: Consequently our geoportal software isreleased as Free Software.2005: Wikipedia meets in Frankfurt, first interest in maps.

Open Geospatial FoundationOpen Geospatial Foundation2005: Autodesk secretly decides to launch their GIS software asOpen Source piggybacking on MapServer. The community isaghast! 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 teamneed?Java/C++: Who is Friend who is Foe?Can there be more than one Best Ever software?...

questions the is born in February 2006:

It is an umbrella organization of initially eight Open Sourcesoftware projects including GRASS. Everybody is happy.

The InternetThe InternetMeanwhile the Internet has become a viable option for distributedcomputing.

Google shows that maps work on the Web.

There are Open albeit independent answers:

OpenLayers - softwareOpenStreetMap - data

Learning Open Data FriendshipLearning Open Data Friendship

Inspired by , adopted for Data Wars

“ Open Data Friendship, also referred to as BeastControl or Beast Trick, is the Force ability to

control data. Once calmed, the data can be usedby the Force user in various ways, including as a

service or INSPIRE beast. ”Star Wars

Public & Government DataPublic & Government DataData collected by the government shall be:

Freely accessibleUnencumbered by legal restrictionsOpen for private and commercial use

The collection, maintenance and provision is funded by thepublic. Therefore It is a public good.

Community Driven DataCommunity Driven DataOften 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 is nowadays used in a different context.crowdsourcing

Use of the data is free and open for anybodyUse of the map service is gratis (but limited)Setting up your own servers is encouragedThe source of derivative works must be made available onrequest (see licensing)
