coordinate system

[Gabriel_C]

Hello All

I'm using Map 3D 2013 (just upgraded from 2012) and Oracle 11g R2.

In Infrastructure Administrator i assigned a coordinate system for an existing industry model (previously it was set to None). 

When i open Map 3D, assign the same system, generate the graphic and i try to digitize a new feature (point, line etc.), the feature appears in an other location, very far from where i drew it.

Any thoughts?

Thank you!

Hi Gabriel,

when you assign a coordinate system to your industry model Map will automatically assign the matching coordinate system to the drawing when you generate graphics. Just try generate graphics without assigning a CS in Map. As Oracle and Map have different CS libraries - are you sure you chose the right one in Map?

Hi Rob,

In Map i chose the one with the same SRID as in Oracle. If I generate graphics without assigning a CS in Map, when i try to digitize i get the message "no coordinate system has been assigned".

I understood from another thread that there is a problem with namemapper.csv, it does't link correctly the CS.

Thank you!

Hi Gabriel,

I didn't know that - sounds plausible. If you want to have it double checked - let me know the SRID code and I will perform a quick test on my side,

Hi Rob, In Oracle i used SRID 31700 and in Map EPSG 3844. Gabriel

Hi Gabriel,

I can only confirm your observations. Oracle contains a definition for 31700 but not for 3844 and in Map it's the other round.

I remember faintly that I heard / read somewhere about the following "workaround":

- create a new CS in Oracle

- use the WKT definition from here: http://spatialreference.org/ref/epsg/3844/  (should match the one used in Map - I don't know if you can get the wkt string out of Map - but you migth be able to get it from MapGuide)?)

But I do not know how complicated creating a new CS definition in Oracle is. Maybe there is an better/easier way to solve the issue? I'm not familiar with CS issues - can't really help here I'm afraid,
