f(GIS) PROJECT The idea, design and implementation of this software belongs to Victor Wagner . Unfortunately he had leave GIS area and this project was dropped for several years. Now it is maintained by Andrey Kiselev . fGIS stands for "functional GIS". It means that fGIS uses functional data model rather than object-oriented. Spatial phenomena are interpreted as functions of spatial coordinates, defined on some subset of earth surface. Such subset can be contineous area, or set of lines, like transport or hydrography network, or even set of isolated points. I hope that such approach would allow to develop powerful map operation language much like simple relational model of tabular data give birth to SQL. Idea of fGIS was born when I've worked on DOS with EPPL7 and Arc/Info GIS systems. I've found that on most tasks, related with natural sciences, EPPL7 outperforms Arc/Info hundred times or so. So, I wanted to have system which is open-source, have purified ideology, and is free from some EPPL7 limitations, caused by 16-bit nature of DOS. Later I've found that GRASS already implements most of my ideas, but GRASS is huge and knowing how other raster GIS like IDRISI are outperformed by EPPL7, I have very few hopes that its existense makes my efforts useless.
