[Proj] PROJ.4.x and Krovak projection

[Martin Landa]

Dear PROJ.4 developers,

trying to build proj-4.5.0b2 I found out, that there is nothing new
with Krovak projection. As I know Radim's patch [1] has not been
implemented yet...

Please, see bugreports

http://bugzilla.remotesensing.org/show_bug.cgi?id=1133

and

http://bugzilla.remotesensing.org/show_bug.cgi?id=147

I am sorry for disturbing you but it is really *frustrating* for Czech
and Slovak users who use PROJ.4 in connection with GIS software
(GRASS, QGIS, UMN MapServer, etc).

I have tried to modify Radim's patch for version 4.5 and write another
patch which adds new option '+czech'.

krovak.c.patch (Radim's original patch modified for 4.5)

echo "15 50" | proj +proj=krovak
-703105.69      -1058219.60

krovak_czech.c.patch (+czech)

echo "15 50" | proj +proj=krovak
-703105.69      -1058219.60

echo "15 50" | proj +proj=krovak +czech
703105.69       1058219.60

I hope this problem will be finally solved...

Best regards,

Martin Landa
