USGS EarthExplorer

I discovered a new resource for researching prototypes and thought I'd pass it on - the USGS's EarthExplorer site.


I've been looking for OE/SP&S track schematics and ROW photos from the early BN era because a lot has changed in western Oregon since the 70s. The BN and SP ended up abandoning parts of the respective lines and sharing trackage and the lines became even more homogenized with the P&W/W&P takeover of BN and SP tracks in the 80s; plus a lot of urban development has occurred in terms of the industries along the lines - buildings torn down, industries expanded, etc. So field research, using contemporary tools like Google Earth, etc. has been hit or miss. The EarthExplorer site offers old Federal gov't aerial imagery, a lot of it high res, and I was able to find images dating back to that time period to help my research. I found aerial imagery from 1974, which helps me discern what structures still exist and identify new architecture and infrastructure that I should exclude from my layout planning.


Check it out.
Now seeking Pacific NW N scalers to create a Modutrak-style modular club featuring NP's shared mainline between Seattle and Portland. PM me if interested.

They sure don't make it easy to find the results, do they?

Agreed, the interface isn't exactly intuitive. I tried it the other day at work for about 5 min - with no usable results. Will go back to it though. Thanks @sizemore

That interface is a bear. I've tried to use it for other projects. Good stuff, but have to "guess" what category of resource might be available for a given location.

 If you are just looking for historical topographic maps, this one has a very simple interface.

I just added a post about this to the "Research" board.
