Summary

Open Source is just a model. Check how it has been implemented in the software you want to use.

Open Source Service Providers get you up to speed.

Use the right software to do the right thing. One solution does not always fit all!

Acquire your own know-how.

Invest your money in small improvements, not in one big chunk!

The Business Proposal ● Rent an STDM Service Platform and work on it with as

many users for as long as you need it. ● Once done, migrate all the data off. ● Or – simply take over the machine and continue

working as if nothing happenend – at no extra cost.

Service Level AgreementThe service level agreement with Metaspatial gives you peace of mind that services are online when you need them, the software is secure and up-to-date and your data is backed up.
