I am working years with MicroStation from very start to todays, for Slovakia in library as Europe/Czechslovakia was GCS as S-JTSK valid for both countries,
btw Slovak and Czech Republic are separated to two independent republics from 1993 , so it could be fine to divide it in library too,so I say why
I never had any in problem with GCS, but after MSCEU7 , S-JTSK for Slovakia dissapeared from library of GCS and was replaced with s-JTSK 05 , but this GCS /JTSK05 is not valid for Slovakia and and so Slovakia missed valid GCS in library MS
I wrote about this really serious problem months ago , problem is not only in MSCE but in all application with MSCE core, as AECOSim, ORD,ORCS, CC and so on , i found it when ORCS informed me about unknown GCS and was not able to work , and old dgn with S-JTSK was out of data, :-(
I had to go back from MSCE to V8i, because all cadastre data are in S-JTSK
now is released MSCEU9.1, but library has not GCS for Slovakia again , it is really frustrated , how to explain to investor serious and curious problem,
it could be fine to see in MSCEU10 in Library of GCS : Slovakia /or Slovak Republic with valid systems by geoportal /geodesy of Slovak Republic are:
S-JTSK : EPSG::5513 (South-West), ::EPSG::5514 (East-North)
S-JTSK03 EPSG:: 8352 (South-West), EPSG::8353 (East-North)
or old s-jtsk from V8i,V7 and pls. dont forget to insert into all relevant applications for slovak users could use them
regards and soon
S-JTSK can be found under Library-->Projected-->Legacy
Are these effective at all for you?
David Trejo-Rodriguez said:Are these effective at all for you?
No, they are not.
In the past, many users used EPSG:102067 and it was supported by geo services like WMS. But this GCS has always been treated as temporary and not "official one" (despite of it has own EPSG id). It's available in MicroStation and properly marked as deprecated., in Czech Republic thisGCS has recently been removed from a list of officially supported projection by e.g. Czech Cadastre.
The most important GCS for Czech and Slovak users is EPSG:5514 with it's alternative EPSG:5513. I am curious how GCS in MicroStation are implemented, because these systems are official part of EPGS database including their ID (contrary to other JTSK varianta not managed throug EPSG authority, so without EPGS ID), their WKT files are defined, supported by all standard libraries (Proj4) and systems supported by OSGeo, but MicroStation ignores it.
I agree with Karol: MicroStation CONNECT Edition as is delivered is not suitable for use in Czech Republic and Slovakia because it ignores standard geodetic coordinate system and projection. I heard from several users (not only from Karol) this problem was reported long time ago but evidently still not solved.

Hi David, I know this legacy ,and effective maybe a little bit, but it doesnt works throught applications as ORCS, ORD an so on
for us as slovak and czech users it is a serious problem, indeed
Hi Jan ,
I really appreciate your support ,
I am sure this problem needs a few days of concept and cooperative work and whole problem with GCS will be done and finally right , I hope that guys from Bentley /dev.dept. it understand the same
thanks and regards
We are currently cleaning up coordinate systems for Czech republic and Slovakia. The way geographic coordinate systems are defined in Bentley products is that the coordinate system not only defines the projection from map to the model of the Earth but also the transformation from one model to others. This way Bentley users need only select the GCS and the datum transformation need not be specified but is included in the selection.
Coordinate System EPSG:5314 (S-JTSK / Krovak East North) is based on the geographic2d coordinate system EPSG:4156 (datum 6156) and the EPSG database defines multiples transformation to ETRF89. We will be introducing missing entries for Slovakia and a minor fix is made for formerly used transformation over Czechoslovakia.
We will then have five different definitions for EPSG:5314, one of which is for older Czechoslovakia maps, two for Slovakia and two for Czech republic one of which is not defined in the EPSG database. We also added EPSG:8353 (S-JTSK [JTSK03] / Krovak East North) and EPSG:5516 (S-JTSK/05 / Modified Krovak East North) had already been added in a previous update of MicroStation CONNECT Edition.
You will see that we only added East-North variations as MicroStation usually requires horizontal axis increasing rightward and vertical axis increasing upward. It is possible to support other axis direction using view rotation, auxiliairy coordinate systems, or specifying a different Quadrant value in the coordinate system definition. If needed variations can be introduced with a user-defined Geographic Coordinate System definition by clients.
All these should be available in Update 10.
Concerning the Czechoslovakia folder in the Geographic Coordinats System selection dialog it was already scheduled for splitting in Update 11 as UI has been frozen for Update 10 many weeks ago.
Finaly I have contacted the Product Manager for ConceptStation products and noted the incapacity for users to select Legacy Coordinate Systems. We will work on a solution for this not to happen again.
