See my previous post here to see the full process. This is an expansion on this process to bring in more or better quality imagery.

Once you have setup your coord system etc. as per previous post, you then want to zoom your screen down to the desired resolution. I find going one zoom level further in than you like is usually a good strategy.

Now you want to keep pressing “save as image” then panning your screen around to get the tiles you desire. Just use your middle mouse button, don’t zoom in and out. Give the images about 5/10% overlap.

Once you have saved all the images you need. Just read them back in to have a look at the finished result. I have saved 6 images below.

Now I want to merge them together as one image.

Raster -> Miscellaneous -> Merge

So now you just need to output your merged image in the desired coordinate system.

Right click the layer and press “save as”

Make sure you tick “rendered Image” and specify your desired coord system.

Give it a short moment to output

Now read into cad. Don’t forget to set your units to “meters” on command INSUNITS if you are using the metric system.

You should now have an image in CAD that is better resolution, or covers a more vast area
