Hello Jan-Oliver,

I'm a bit puzzled by the cross-post you sent to the FreeGIS list since
it started in the midstream of the exchange. Here, is a quick take on
the some issues in the use of GIS for spatial research in agricultural
systems. It may be helpful to Mr. Roger Longhorn. These issues have no
relevance to the financial costs of the software but rather pertain to
the control of the tool. Could you please forward it to him if he is not
on the freegis list?


While there are many arguments in favour of *free* software, the ability
to modify the source code is critical for any research using geographic
information systems. If Mr. Longhorn and the CGIAR intend to use GIS for
spatial research in agricultural systems, success will only come from
the long term accumulation of useful tools, routines and data. Contrary
to what the commercial vendors repeat, our understanding of spatial
analysis is not nearly sufficient to be able to rely on pre-packaged
algorithms for analysis. The major costs to the consortium will be
involved in the time required of the research scientists to develop
useful models, build a coherent set of baseline data and develop useful
analytic algorithms. This investment will only be recouped by the
consortium if, at the end of the process, it has a tool that it can then
use in perpetuity. The difficulty in getting an estimate of the growth
of cassava across Africa, for example, does not lie in mapping Africa
but in getting a reliable set of weather estimates, a reasonable plant
growth model and a decent estimate of the areas where cassava is grown.
By all means, CGIAR should pay for software to help shorten their time
to completion, but the consortium should buy *free* software and pay for
consultants to help the consortium's scientists program the models,
acquire data and understand the issues involved in spatial analysis.
These consultants, and the product of their labour, is the key to the
successful use by CGIAR of GIS for research. Even the best spatial
ecologists don't understand the robustness problems involved in the
manipulation of several data layers, ignore the issues of error
propagation and misunderstand the applicability of the statistical tools
in spatial analysis. Purchase advice and help, not licenses. The
alternative will be a slew of projects, each having its analysis
assembled piecemeal and no simplicity gained over the next few decades
of work. 

On the other hand, if the CGIAR is using GIS to map current situations
for funding proposals or to illustrate political statements, current
proprietary software is probably sufficient, quick and easy. However,
once again the product of the labour of the researchers of the
consortium will only be partly available to the CGIAR. There will be no
way, for example, to share with government agencies or university
research groups around the world the analytic tools with which the CGIAR
reached its conclusions. 

The best solution for the CGIAR would be to join the FAO and several
other groups, allocate a source of funds over the next five years and
pay someone to assemble one, or several complementary, systems to serve
their needs. At the end of the process, the consortium would have a
system that it owned, that it could modify and that was targeted to its
particular needs. 

Good luck in whatever path you choose,
