I am using ArcView 3.2.=20
I have a polygon shape file that is the Great Lakes. Coarse resolution.
I have a line shape file that represents the water's edge (lakeshore as wel=
l as rivers and streams). High detail.
The lake edges do not go as far inland as the shoreline which means that th=
e shore roads are a long ways from the water's edge on my maps. OK when zoo=
med out, not so good when zoomed in.
The shoreline is far more accurate and agrees with the roads and villages l=
ayers that I have. Is there some way I can buffer or otherwise expand the l=
akes polygons out to the line representing the shoreline such that the accu=
rate shoreline now becomes the lake edge?=20
Any suggestions greatly appreciated.
