Bing Maps does not map with the drawing.

[Anonymous]

Hello AutoCAD Team,

I am new user to Civil 3D and I have background in Systems Engineering. I am facing problem synchronising Bing maps with my AutoCAD drawing . I have site plan obtain from the Measurement Department ( Vermessungsamt). The coordinate system mentioned on the Website was ETRS-89 UTM32.  I used the command  geographiclocation, entered the latitude and longitude from the maps. selected the geo point , selected the coordinate system and time . At the end bing maps does not synchronise with the drawing . Could you please help me what am I doing incorrect. The dwg and snapshot of the image are attached please. 

Second question is that When I select the ED50-UTM 32  coordinate system during the geolocation command , and then later assign the ETRS89-UTM32 to the drawing , bing rotates automatically and fits perfect to the drawing. But the problem is the geo point coordinates are false. Is there a way to set the geo point manually.  I actually need geo point , which I later used for planning the solar pv system in other software. 

Many thanks in advance and Have a nice weekend !

Best Regards

Hello Saad

>> I used the command geographiclocation

Don't do this if you are using MAP or Civil 3D.

First, delete all overwritten CS settings with _GEOREMOVE.

Then start the MAPCSASSIGN command and search for 25832 = ETRS89.UTM-32N.

Assign this coordinate system. 

Finally, you can show the Bing Maps with

Command: _GEOMAP _Hybrid

When using Civil 3D it's a good idea to show the assigned CS in Statusbar.

Command: _MAPSTATUSBAR _ON

You are also welcome to ask these questions in the German Autodesk Forum.

Hi Saad,
I agree completely with Udo. To add to his excellent advice, the Geolocation Command is intended for Vanilla AutoCAD and is quirky, at best, with Civil and Map. If you want to find a particular spot use Zoom >> Center >> 'LL.

Thanks Udo and Dave,

But actually I would to like synchronise the DWG with Bing maps using geolocation command. I am actually using another planing software which runs on the top of the AutoCAD Civil. The software uses geo location option for further calculations such as Sun altitude, shading calculations. Is there any way to synchronise the Bing maps with geolocation command. Many thanks in advance and Have a nice weekend !

We do not know the values used, but they are probably wrong or inaccurate.

Why select a geopoint manually when Civil 3D already knows the correct coordinate system? What advantages do you expect? Currently, I can only see disadvantages.

Hello Udo,

I forgot to attach .kmz file. The software has dependeny on the  AutoCAD geo location to perform shading analysis and to perform solar calculations. The software works on the Top of the Civil 3D but it uses the geo location AutoCAD command to perform solar calculations. The issue is already raised to concerned software representative. I also see the disadvantage to enter the geopoint manually.  Special Thanks Udo for your quick response and realising the problem.

Saad,
"...works on the Top of the Civil 3D but it uses the geo location AutoCAD command to perform solar calculations."
The GeoLocation Command in Civil 3D and Map 3D puts you in einer schwierigen oder hoffnungslosen Situation; ruiniert oder kaputt.
The shift in your "Flürstuckkarte Köllig right geo location but bing maps not synchronised.dwg" is caused by using the GeoLocation Command. If you use the GeoRemove Command and then reassign ETRS89.UTM-32N coordinate system with MAPCSASSIGN, your drawing is fixed.

Hello Dave, 

The geolocation is putting me nicht in Hoffnungslosen Situation, ruiniert oder kaputt. 

I am fully motivated , Die Lösung Udo oder du vorgeschlagen hast, does not fit to my requirements. Probably you did not understood my point. Wie habe ich erzählt, I use Helios 3D software,  which performs shading calculations to place the PV Module Tables on the ground. Ich habe das Problem an Helios 3D Team weitergeleitet. 

I am not German and not English ! I want to appologize, if I use the language improperly. 

Ich wünsche euch schönes Wochenende 🙂

Saad,
I haven't used Helios 3D, so I don't know how it works with Civil 3D. If the Helios people can't help you, then you might want to consider using Vanilla AutoCAD for the work, if possible. The GeoLocation Command works in Vanilla AutoCAD.

It looks like the solar program you are using with AutoCad wants you to enter Lat/Longs. Is that correct? To get accurate lat/longs, you must first georeference your drawing to Kӧlig because if you don't georeference then your solar input will be useless. Does that sound right?

The drawing you uploaded, Flurstuckkarte Kollig.dwg is referenced against ED50-UTM32 (EPSG 23032). Either the Measurement Department or you have made a mistake because it is not referenced to ETRS89.UTM-32N (EPSG 25832).

It's not clear which coordinate system you will use in your drawing. ED50? or ETRS? The lat/longs (degrees) will be the same in both coordinate systems. The X/Y's, however, will vary from one coordinate system to the other.

What coordinate system do you want to use when drawing in Civil 3D?

If you find any problems with Helios3D and Civil 3D, then ask Helios 3D Support first.

Hello Chicagolooper, 

Thanks for your understanding. You are 100 percent right, the solar program uses georeference to get accurate lat/longs, we first georeference the drawing to Kӧlig because if we don't georeference then your solar calculations will be useless.

I have confirmed from the Measurement department, the coordinate system is ETRS89.UTM-32N (EPSG 25832).

What I understood so far that AutoCAD geolocation and Civil 3D mapcsassign use Bing maps API in different way. The both commands have different algorithm/ Method and the results can vary. 

Thanks to all guys, @Udo_Huebner  Specially Udo ! Your efforts are highly appreciated. I have already shared  the  issue with concerned Software Team.

Have a nice weekend  !

Best Regards

REVIEW THE YELLOW PUSHPIN IN GOOGLE EARTH PRO:

Here's a demonstration which begins with a yellow pushpin in Google Earth Pro, refer to Kollig.zip in post #6 of this thread. (The location of your specific pushpin may vary and could be anywhere in the Google map area.) The pushpin's location can be expressed in geographic coordinates of lat/long degrees OR projected in UTM in meters. To switch from one coordinate system to the other, go to the Tools=>Options section in the toolbar. Write down the geographic lat/long and the UTM X,Y meters. You'll need to input those coordinates to successfully run the geographiclocation command in AutoCad.

BACK IN AUTOCAD MODELSPACE:

Perform the geographiclocation command by following the video. After completion, the coordinate system will be established and you can check accuracy by inserting a new AutoCad geomarker. The geomarker's X,Y coordinates, when viewed in the Properties Palette, are relative to your established, or assigned, coordinate system. Scroll to the bottom of the Properties Palette so you can view the geomarker's Lat/Long. As always, lat/longs are relative to the North Pole and Equator and not relative the assigned coordinate system.

WARNING: the accuracy of the geomarker is limited to the precision of the Lat/Long and UTM coordinates you have inputted into the geographiclocation command.

HINT: You may also use the MAPCSASSIGN command to establish your coordinate system. You can consider mapcsassign to be a Best Practice. The mapcsassign command is only available in Civil3D and Map3D. Plain vanilla AutoCad does NOT have it nor do other vertical products. When available, Use MAPCSASSIGN rather than the geographiclocation command, it's simpler and faster.

NOTE: Whether you use GEOGRAPHICLOCATION or MAPCSASSIGN, neither method will relocate or move your objects to their correct geospatial location. If the objects are not georeferenced the author, then you, the user, must manually move, scale and rotate those objects AFTER you've assigned your coordinate system.

To watch the video click >>HERE<<.

Did you write down the yellow pushpins lat/long and UTM coordinates? Compare the new AutoCad geomarker with the yellow pushpin's lat/long and UTMs. If your drawing is still not correct, then you have not assigned the correct coordinate system or the objects in your drawing were not accurately drawn in the first place.

Hi, 

Thanks Chicago Looper, The video was really helpful. 

Thanks to all Guys. Your efforts are highly appreciated
