[Freegis-list] new release of the libral, Geo::Raster, Geo::Vector, Gtk2::Ex::Geo stack

[Ari Jolma]

I've created a new release of this software stack. The release is
available at the Files section at http://sourceforge.net/projects/libral
and at CPAN (only the Perl modules).

This stack (I don't have a good name for this...) contains libral, which
is a fast and easy to use raster algebra library, Geo::Raster is a Perl
interface to libral and a layer class, Geo::Vector is a vector layer
class, and Gtk2::Ex::Geo is a set of widgets, dialogs and glue code for
developing geospatially aware applications using the modern Gtk2 GUI
toolkit with Perl (using the extremely powerful Gtk2 modules).

Goals of this software are to

- combine GUI+CLI (Gtk2::Entry widget can be used to enter Perl commands)
- be easily extandable with new layer types (I'm working on a raster
timeseries class/layer for example) and add-ons
- be a toolkit for application developers (I have student projects
especially in my mind)
- be an scripting/analysis environment (I'm looking for ways to link
this to Grass, R spatial, and other tools)
- support civil and environmental engineering (we have done some work on
hydrological applications/research of libral)

The release contains only source code, but it should be easy to
configure and install on Linux and probably on other unix like OSs. Main
non-standard requirements are GDAL/OGR (with Swig/Perl interface) and
gtk2-perl.

The stack contains a simple application for viewing, browsing, and
analysing geospatial data. The closest counterpart is perhaps OpenEV,
which offers somewhat similar functionality but uses Python.

I'm especially looking for, besides a good name for this, people who
would be interested in making a binary Windows release.

Enjoy,

Ari
