[Proj4j] request

[Nyrtsov Maxim]

Dear colleagues!

 

We would like to offer to you to include in the library of projections
"proj4" oblique perspective-cylindrical projection. Normal
perspective-cylindrical projection (projection pole is 90°) is included to
the projections list of "proj4" under the name of Gall projection. However
there are many Russian maps in oblique perspective-cylindrical projections.
These maps are scanned and needed to be correctly georeferenced in GIS for
later use. Particularly in one version of this projection (TsNIIGAiK
projection - coordinates of pole of projection are 25°N, 80°W) about 100
maps from National Atlas of Russia has been compiled. Among them there are
such maps:

*	Seismicity of Russia and adjacent territories
*	The largest deposits of minerals
*	Soil Map of Russia
*	Vegetation Map of Russia 
*	Nature conservation and environmental management
*	Functional types of settlement
*	Russian Empire in the XVIII century.

 

Another version of oblique perspective-cylindrical projection (Solovyev
projection - coordinates of pole of projection are 75° N, 80°W ) has been
used in our country for school maps since the 30s of the last century. In
this projection contour maps were created which has been used not only
scholars but also by scientists geographers to apply unique information.

 

If you are interested in our offer we are ready to provide the projection
formulae (forward and inverse).

 

Sincerely yours,

of Sciences, Moscow, Russia)
