This image is too small - that is were you are finding difficulties.
You have to enlarge it - I'd say 400% would do - convert it to RGB
mode first (image->modes->rgb) ,then scale it up, enhance the
contrast (I like doing this using the layers->colors->curves tool,
applying an 's' shape. Brightness Contrast tool should work fine
here too).
At this stage, you probably will want to retouch the picture with the
pencil tool. It is so small that some details - on the windows and on
the clock, are not separatable even doing a manual retouch - you
willhave to redraw the clock dots and window frames, unless you hhvae
a scaled upo version of this image.
Them,. select by color, click on black, convert selection to path.
Then, fine tune your path, trowing away undesired points - this will
smooth the curvers.
It should work.

I am trying to convert the attached image into an SVG (vector
graphics) image with no/transparent background. I know something
about layers, masks, and channels, but cannot find the correct set
of operations to extract the black components of the base image and
reconstruct them as one vector graphics image that can then be
resized without "pixellation" (blurring/loss of pixels) and saved
as other image types.
My original thoughts were to extract the two major black features
using a mask. Fill in the outline where it is overlayed in the
original image so it would then be complete. This should then be
easy enough to convert into a "path", or otherwise convert into a
vector graphics image by itself.
The remainder of the original image, the "tower", would take
several steps to seperate ITS component sections, and then convert
them into a "path", or seperate SVG.
Once all of the components have been seperated and converted, it
should be easy enough to combine them into one SVG, which can then
be expanded or otherwise modified without any more problems,
leaving it with a transparent background.
I have tried to go through the Gimp User Manual but can't seem to
find all of the necessary steps, or the proper order, to produce
the desired, final SVG, and find myself getting somewhat lost.
Any suggestions to accomplish what I need will be most welcome.
