[OSM-newbies] newbies Digest, Vol 27, Issue 1

[Donald Campbell II]

Hi Bob.  I'm not an expert at this by far but I can explain a little bit the
scale.  Let's say you have the area you want shown in the map and change the
scale value.  The resulting image will be larger or smaller depending on
scale, and will show more or less detail depending on the size of that
image.

Make sure when you look at the resulting image that your viewer program
isn't automatically shrinking the image to fit on your screen.  Verify that
you're looking at it zoomed in all the way.  Many web browsers and image
viewers normally shrink your image to fit the screen, this could give the
appearance that changing the scale didn't have any effect.

To put it another way, the scale factor is like the difference between a
thumbnail of an image and the full resolution image, they both look the same
but one has much more detail and can be printed in a larger size.
