Hi All,

I have a job where the client has specified a that they want to use a modified Briesemeister projection (basically a southern hemisphere version) showing Antarctica.

Does anyone know what software I could use to generate this?

I use FH and Ill. on a mac mainly. The map needs to have fairly crisp linework, as will be printed at A3.

Thanks in advance,

Tim

Well... I checked all applications I have that do reprojections (MAPublisher, Manifold, Global Mapper, FME), and none of them have the Briesemeister projection. It's available in Geocart though. Hope this helps.

Hi Hans!

Many thanks for the reply, you saved me a lot of frustration downloading demos of these programs and not finding the projection I needed in them!!

GeoCart looks like the one for me, and it will be even better when v3 is out early next year!!

Once again, thanks for the reply!

"This projection was presented by William Briesemeister in 1953. It is an oblique Hammer projection with an axis ratio of 1.75 to 1, instead of 2 to 1."

This PROJ.4 document lists it, but I can't see how to use the proj.4 string.

This doesn't work with OGR, does anyone know how to do it?

ogr2ogr Briese.shp World.shp World -a_srs "+proj=longlat" -t_srs "+proj=ob_tran +o_proj=hammer +o_lat_p=45 +o_lon_p=0 +lon_0=10 +M=0.93541"
