geoscript / geoscript-ruby Goto Github PK

In order to allow for GeoScript only functionality to be available on output, GeoScript geometry objects should be returned on output from functions like geom.buffer(), etc.

The use of super in the initialize step on the geometry objects provides a more elegant means to create the JTS geometry and use as a GeoScript geometry. Moving to the use of super in initialize in place of geom.create() for all geometries.

Trying to use the gem to reproject coordinates, I encounter some weird results:

g = GeoScript::Geom::Point.new 6.15, 46.200
g_lv03 = GeoScript::Projection.reproject g, 'epsg:4326', 'epsg:21781'
g_lv03.to_wkt
=> "POINT (10520353.212507451 117323.41286581586)"

Using the same transformation but using proj4 instead:

$ cs2cs +init=epsg:4326 +to +init=epsg:21781
6.15 46.2           
500532.75   117323.35 -52.49

The ordinate seems correct, but not the abscissa
