Improving the resolution of a raster image

How did you capture the image?

Was it internally through Microstation itself, or are you importing it as an external file?

Hi Doug,

In fact I have captured it in Microstation but did not know how to save it inside the file, so I saved the image and attached it again as a raster. Is there an easier way for doing it? 

When I imported the raster I noticed it has a poor resolution. 

Was it via this method?

yes indeed. I have watched this video and applied what he said. The thing is that, if I make a capture for part of the aerial photo and save the file, it disappears when I open the file again.

Importing is poor resolution as it creates legacy 256 color bitmap element. Only option to embed is use paste as picture then it creates OLE element but it takes lot of space as it is then for compatibility BMP format(internally slightly compressed with ZLIB).

if your using  bing as the back ground view as  in the  youtube you dont need to capture  it  just save settings before you close the file and  it will always display  provided you have internet access turned  on.. now a few tips.

I would create a new 3d file drawing same coordinate system and ref attach your drawing and zoom to suit  the coverage you want, now turn off your ref file drawing and use the google earth tools to display the aerial data  you can look up how to capture google earth imagery in colour and   have it match the mesh area in your 3d dgn.. takes too long to describe every step there is a bentley wiki on the full instructions. The capture resolution is  pretty high provided you dont  try to capture too big an area.. but it is  google earth and  may not  be as upto date as bing no promises there ... but I prefer GEarth as once captured  doesnt need internet, but  Bing will always be the most upto date version everytime it loads from internet...this might be a bad thing.. depends on your needs.

If you have a license to use MicroStation Descartes you can use the Merge command in Raster Manager to capture an area of the Bing Maps imagery and save it to an image file. You can specify any resolution, but the best you can get is the base resolution of the Bing imagery. If you exceed that resolution you are just creating excessively large images and gain no benefit.

If you choose to save to a geo-located format, the image can easily be attached in the correct geo-located position through the Raster Manager. You can also generate a sister file for use in positioning formats like .jpg images in the correct geo-location.

NOTE:
I don't know if this violates any of the Bing Map Terms of Service, so you should verify that it is ok before.

Thanks for the feedback Ron.
