  • PostGIS 1.5 lançado!

    8 de fevereiro de 2010 · Categoria: Softwares

    O PostGIS 1.5 chegou chegando com excelentes novidades para a turma. Uma delas, em especial é o novo tipo Geography, que se pode utilizar para realizar cálculos preciso de distâncias contando a curvatura do globo!

    Não deixem de conferir!

    “The PostGIS development team has, after a long course of reflection
    and a detailed self-examination of our various personal failings,
    decided to release PostGIS 1.5.0 to the public.”

     http://postgis.org/download/postgis-1.5.0.tar.gz

    This new version of PostGIS includes a new “geography” type for
    managing geodetic (lat/lon) data, performance-enhanced distance
    calculations, GML and KML format readers, an improved shape loading
    GUI, and other new features as well.

    Especial thanks to:

    * Dave Skea for algorithms and mathematics necessary to support
    spherical geometry
    * Nicklas Avén for the new performance enhanced distance calculations
    and other distance-related functions
    * Sandro Santilli for new buffering features (end caps and style options)
    * Olivier Courtin for GML/KML input functions
    * Guillaume Lelarge for support for the upcoming PgSQL 9.0
    * George Silva for an example implementation of history tables
    * Vincent Picavet for Hausdorff distance calculations
    * The maintainers of GEOS, Proj4, and LibXML, without whom we would
    have less of a spatial database

    Love, the PostGIS project steering committee,
