Geo::Raster Description
Geo::Raster is a Perl extension for raster algebra. Geo::Raster is a Perl extension for raster algebra.SYNOPSIS use Geo::Raster;or use Geo::Raster qw(:types);or use Geo::Raster qw(:types :logics :db);Geo::Raster is an object-oriented interface to libral, a C library for rasters and raster algebra. Geo::Raster makes using libral easy and adds some very useful functionality to it. libral rasters are in-memory for fast and easy processing. libral rasters can be created from GDAL rasters. GDAL provides access to rasters in many formats.Geo::Raster also adds the required functionality to display rasters in Gtk2::Ex::Geo.Each cell in raster/grid is assumed to be a square.The grid point represents the center of the cell and not the area of the cell (when such distinction needs to be made). TODO: This needs more attention.A grid is indexed like this: j = 0..N-1 ------------------> .i = 0..M-1 . . . Vthere is also a (x,y) world coordinate system maxY ^ . . y . minY . ------------------> minX maxX xminX is the left edge of first cell in line. maxX is the right edge of the last cell in a line. minY and maxY represent similarly the boundaries of the raster.
