This is a long shot, but would anyone happen to have a historic shorelines GIS file for the Columbia River in Oregon?

 

I'm working on a project where having the pre dams shoreline of the river could be helpful, but we don't have the time required for me to digitize it now.

 

Thanks,

David

I'm sure you're aware of the NOAA historic charts.  Mariners have a strong interest in knowing exactly where the shorelines are.

Alas, they're raster images, which may not help you much.

Yes, and actually I even tried using the modern NOAA ENCs for the Columbia, hoping I could use the vector lines for a particular depth that mirrored the old shoreline. But the ENC lines are a mess, it would be faster to redraw from the old maps, but still too long for this project I think. I have very limited amounts of time to use each week towards the project and I'm already doing way more on my own time then I should ; ).

 

Oh well, I think it's just one of those things that would have been great to do if there had been more time upfront.

 

Thanks,
