Aerial Photos - Marin County

[LS_8750]

I'm looking for aerial photos of Highway One along the shore of Tomales Bay.
Ideally mid 1960s and mid 1970s.

Any input would be great.

Cheers.

You might check with Caltrans District 4 records and they may have some historical photos, either a inventory set or a photogrammetry project.

You look up aerials for most of the US, and they can have multiple years (hence the historic part of their name) for the same area too. (I just looked, and they only have 2005 - sorry)

Its also neat to look-up where you live(d) and see the changes over the years..

Google earth has historical aerials too.

Google earth has historical aerials too.

He is looking for older stuff, I believe Google Earth photos only go back about 10 years in most areas... but very handy for recent changes

I have one set of photos from 1976 of the whole county, but your best bet is Caltrans if you are along the highway that existed in that time frame. They have inventory aerial photographs of all of the highways taken every 10 years, I believe. My photos are 1â€￾ = 1,000’.

The County of Marin also had inventory photos taken every 10 years. It has been 20 years since I looked at them. Hopefully, they did not throw them out with all of the unrecorded maps they used to have.

I attached the area near the town of Tomales, taken from my phone to give you an idea, since I had the book of photos in my office for another project.

I'd have to agree with Larry - Caltrans HQ Office of Photogrammetry (OoP) is the definitive source of aierial imagery information for Caltrans routes:

Another source is the US Soil Conservations Service of the USDA.

Let's not forget the State Lands Commission. Thanks Evan.

Dylan Gonsalves gave me a nice lead as well: earthexplorer.usgs.gov

If I could only find a set from about 1965. Perhaps Caltrans or perhaps SLC. The search continues.

Oh, and have a look at the attached photo. A little piece of forensic genius (that we all know of). Overlaying paper printouts of aerials and then raising them up into the sunlight.

Cheers.
