Refine a vector layer in ENVI [message #49049] Wed, 14 June 2006 15:25 Go to previous message

I've come across the following problems several times, and I'm
wondering if somebody know a way to fix it. I have shapefiles of lakes
in a region, which was produced about 40 years ago. When I overlay the
lake shapefiles to a recent Landsat image, the shapefiles do not
outline the lakes exactly for the area of the lakes have changed over
the years. So I want to edit the vector layer to make it fit the
outline of the lakes in my Landsat image. This doesn't seem to be
difficult using the Vector Parameters dialog in ENVI (Mode/Edit
existing vectors). However, when I drag the nodes to move them in the
desired location in the right side of the vector layer, the whole
vector (or the left side of it) moves too! When I fixed all the
problems in the right side and saved it to the layer, and start
editting the left side, the right side of the vector layer moves again
with each editting. Thus I can never make it fix a whole lake.

Does anybody have similar experience? Or is this a bug?

Thanks,
Jenny
