I work for Oxford Archaeology as an IT Support and Development Officer, and also as a Geospatial Consultant for our spin-off consultancy OA Digital. Oxford Archaeology are the largest commercial archaeological unit in Europe, employing around 400 staff in 3 British and 2 French offices. We use GIS a great deal in all areas of our work, as almost all of it has a spatial component. We made a decision to go open source about 3 years ago, and haven't imploded yet!

I was going to talk about cost savings and licensing, and boring things like that, but decided instead to look in a light-hearted way at the impact open source GIS has on the gis space, and might have on your business

Why Open Source Matters

Interoperability

Modularity

Control

Here's Kate

Open Source provides three main advantages, outside of ideas such as cost

These are: Interoperability, Modularity and Control

With these in mind, it's possible to use open source within your business to expand what you can do in a flexible, fairly risk-free way

Interoperability

Interoperability is in basic terms the ability to share and interact.

Open source GIS programmers have no financial reason to lock you in to a particular file format, or indeed to force you to change to a different format with every release of their software (Boeing)

They have no reason not to make their file formats open, so more people can use them

What this means is that without open standards, and the ability to share data between applications and users, there would be no Neogeography, no Where 2.0, no mashups

Interoperability

GIS standards derive from Open Source

Open standards are the bed-rock of interoperability, and in the GIS world they derive directly from the open source software

The Open Grass Foundation, founded in 1992 to look after GRASS, evolved into the Open Geospatial Consortium in 1994

In 2009 OGC and OSGeo signed a memorandum of understanding, partly around open source GIS packages being used as reference implementations of OGC standards

Modularity

= Agile flexibility

Open source GIS programmers are not trying to sell you a monolithic package that tries to do everything, or only works within their stack

They don't subscribe to Zawinski's Law- that every programme expands until it can read email

There's no 3 year license deal locking you in

Open source gives you the chance to pick and choose the components that you need to do the job, changing as you need to

Modularity

= Choice

This means there's no need to change your existing work-flow if you don't want to

You can slot modules into your stack as you need to, and can change individual components if necessary

Regardless of what Steve Ballmer thinks, the open source licenses don't prevent you from using them with proprietary software. Open source is not cancer, or communism

Modularity gives you the choice to pick the software that's right for you and your business, not what a salesman tells you is right

Control

You're in charge

Massimo Valiani

The open source license gives you the control over your software. You are not at risk of losing your software, or facing increased costs because the software vendor changes the terms of the license.

The open source license is about providing freedom and fair use, not about restricting packages to people from particular countries, or on particular hardware platforms, or on a limited number of pcs/processors

What could all this mean to you?

Freedom

Rapid prototyping of ideas

Diversification

Best Value

If you accept that there is a place for open source within your organisation, what might this mean?

I would argue that it gives you the freedom to try out new things without worrying too much about the cost- try before you buy!

You can rapidly prototype new ideas, and diversify into new products without massive prior financial investment

You can ensure that you get best value from your software- and your software vendor!
