The National Map Corps

Few weeks ago, I "enlisted" in the National Map Corps. Basically, it is a volunteer job consisting in collecting GPS data in a defined area to help producing the National Map of the USA. This is a project managed by the USGS. Closer to Waymarking than to Geocaching...
For the first time yesterday, I went out in the field and spent about 2 hours driving around in a small part of my assigned area (the Los Gatos quadrangle).
I covered only a tiny bit of my quadrangle : the area delimited by Harwood, Leigh, Little Branham (along Hwy 85) and Blossom Hill. I drove through absolutely each and every street, looking for special buildings such as schools, churches, community centers, etc... (USGS provided me with a complete list of features to look for).
It is a pretty tiring job, made of plenty of verrry slow driving and approximative u-turns.
During these two hours, I marked only 5 spots : 3 schools and 2 churches.
Although the schools were on the quadrangle map that the USGS sent me (that was last revised in 1980), the 2 churches were not so it feels like I'm going to help bring more detail to the National Map. Yay!
The collected data are supposed to be sent to USGS once the whole quandrangle is covered, in a spreadsheet format. I'm trying to really use Google Spreadsheet for the first time. I'll update the file after each data collection session.
The most current version of my data file is here. I'm making it public in the hope that people reading this blog and who know the Los Gatos quadrangle area can verify that I didn't miss anything important.
This morning, I was looking at the route I took yesterday and I noticed with horror that I totally missed a few streets. Even though I doubt that there is any feature of interest there, I will need to go back and check, just to be absolutely sure.
Looks like it's gonna take for ever, hopefully less than the one year hoped by USGS ;-)
