I have some questions. I am trialling the free version trying to
capture images from GE with a world file.

(1) The accuracy is not very good. For example if you read the
lat,long of the top of the image in GE it is slightly different to
that created in the world file. Is this on purpose being a trial
version and does the paid version give more accuracy?

(2) the world file is created with decimal lat and longs. Is there an
option to create using UTM meters.

Thanks

There is currently no difference between the trial and purchased
version of
Shape2Earth when it comes to image capture. The accuracy is limted to
keep
within the Google Earth terms of use. I will go double check to make
sure
that the world file and real world coordinates are matching correctly.

Shape2Earth does not reproject imagery to get your data into UTM, but
you
can try some of the tools in MapWindow, or some of the GDAL tools :
