Bing Maps - Incorrect position of Mapping 2015 English

[MikeEvansUK]

Ever since I have updated the Geolocation patch I recieve incorrect locations for bing mapping data. "AcGeoLocationUI.arx is 20.0.210.3 "

Aparently the OSGB Grid now extends into France? I have checked the Lat Long it produces in the Map coordinate box and the Bing translation which are listed as the same.

I select the map position and accept the corrdinates given by geolocation for insertion. The file coordinate system is set to OSGB National Grid, Bing is set the same with GMT(0:000) time zone, meters.

When overlayed with the OSGB Grids from Map shp file there is a definate shift in the bing mapping location. See image.

Any Ideas?

Mike,

From Steve Boon @sboon, in <<<This Thread>>>:

"Map is supposed to be ignoring the Transformation tab, but as noted in the bug it seems to apply the screwed up values when it places the Geolocation marker and imports the Bing mapping. Resetting the values in the Transformation tab so that the Grid values match the Local ones, and setting the Grid rotation to zero appears to solve these problems."

This happens even if your Transformation Tab is disabled:

Oh that explains it Thanks. Seems slightly useless at the moment then unless you already know the exact location of a site in the same coordinates. I assume you need to be exact in picking the same point on the ground and also in maps which I expect to be almost impossible.

I clicked point and guessed and it is closer to the truth but still an epic fail.

Mike,

"I assume you need to be exact in picking the same point on the ground and also in maps which I expect to be almost impossible."

No, Local and Grid just need to be the same. Use whatever is already in the Local Northings and Eastings, copy and paste that into the Grid Northings and Eastings. And don't forget to set the Grid Rotation Angle to Zero.

I tried this and failed.

I got the mapping using the info provided then tried correcting the tranformation tab and re obtained the mapping. This didn't help.

However I seemed to stumble on a simple fix.

I removed the geo position altogether and allowed the removal of the coordinate system.

Re set the coordinate system and checked the Tranformation tab (all values for local and plane matched) Trnaformation set to "ON".

Got the map and it was spot on. Don't know why this worked, I think something to do with the Geographic location.

So to clarify before getting mapping:

Remove / Reset the Geographic Location.

Add Coordinate Spacial Zone

Ensure transformation grids match on tab and transformation is ON.

Get the mapping data.

Thanks for the assistance on this one, has been bugging me for a while. However can others try the above and confirm I am correct please then I'll close the post.

I never use the geolocation to pick a location and the coordinate system. As long as there is a coordinate system assigned to the dwg and there is a least one entity in the dwg (in the location I need and georeferanced) I just use the geomap command to add the maps/image.

Hit the nail on the Head Murph.

I often use the Mapping tool to locate the site on the Ordinance Survey Grid so I can then focus on the area and import Mapping data Aerial Imagery (by OSGrid Tile) and Geospacial features located on & around my site. Often our surveys are not projected to OSGrid coordinates for some stange reason, Probably Cost as some recently have been a small building. So I know not where they are in the world and would have to back work to locate them.

However, I have tried this using a query on place names, nearest town to get a Geo-referanced entity then focus on that area. Then running the geomap command works correctly.

Thanks. Kudos to you Sir.
