Hi, I've got basejump going (broke it there for a while), but now I would really appreciate some pointers on using it effectively. I've got 2 main questions:
1. One thing that annoys me is that the Bing raster seems to want to jump up in the display order after a refresh/zoom so that it obsucres my other work. I couldn't find a layer that the imagery is associated with, so my only temporary solution at the moment is to zoom out (way out), select the image and "send to back". Also, ideally, I would like to load all 3 Bing options (aerial, roads, etc.), then have layers where I can turn them off and on as required. Is this possible?
2. Is it possible to copy of an aerial image from basejump and incorporate it into my drawing so that it works for others that might not use basejump? What I would like to do is get to the required zoom level, define an area of interest and then crop the image to this area and save it to a local disk or within the drawing itsefl
Solved! Go to Solution.
Thankyou Neilyj. exactly what I was after. Yes, I was starting to suspect that it wasn't meant to be easy to actually clip a part of the bing imagery out for later use.
it would certainly be useful to clip out the imagery but I'm sure there are copyright issues re. google earth functionality removed from c3d 2013
I don't know how basejump works but with other raster connections you couls zoom into the area you need, do a resample from the map task pane then export the map to dwg format. This would create a png (in your users temp folder) of the imaged displayed in the editor window that you could xref or insert into amother dwg.
Nice one Murph !
Interesting.... resampling does indeed clip to the screen area. If I zoom in, the image updates to the higher resolution imagery - so it still dynamic, but it certainly seems quicker particularly zooming out as the whole geographic zone isn't being reloaded. If I zoom to extents, the full area is reloaded (effectively undoing the resampling operation), so not ideal from this perspective, but an easy way to reset the image.
I tried exporting, but as a dwg file it didn't seem to work. As a bmp file it worked, but there was no georeferencing information - so I guess would require the rubbersheeting as mentioned previously. Copying and pasting from one drawing to another didn't seem to work either. So it seems a few functions are either disabled or just don't work.
Aside from any potential copyright issues, it would still be nice to be able to save the image with georeferencing quickly and easily simply for my own use - like if the bing connection wasn't working one day, etc. etc.
Murph to the rescue - again...!!!!
@autoMick - did you Save Current Map to AutoCAD from the Output ribbon in Planning and Analysis workspace?? I did this and got a dwg of the base map although the resolution was very poor compared with the original "live" data.
If you wanna georeference an existing image physically loaded in the drawing, you should use this free tool:
Another technique involves the opensource Qgis, which loads Openlayers imagery, saving it as Geotiff.
Neilyj - no I hadn't tried that, I just did export from the C3D menu. I tried your suggestion - and although it worked, I got the same result as you, the aerial photo was pretty shabby.
Antonio - thanks - looks like something to explore.
