If you have software like GIS the OTLS map is easy to make.  Not sure if you can find a free map or PDF out there though.  The stitching or georeferencing the plats together isn't too bad but takes alot of time I've done a few before and that's why I've only done a few...

 

Another route would be to download the data from a free source like TNRIS...

Then download a free shapefile viewer.  Like TatukGIS Viewer.

Use the Texas Railroad Commission's http://gis2.rrc.state.tx.us/public/startit.htm

Select San Augustine County and keep zooming in to see survey names and numbers.

There is also a button to search by survey number.

Have fun!

Johnnie Joe and 5thGenTexan, I appreciate both of these suggestions.  I would like to be able to make a skeleton line drawing of the survey boundaries and superimpose that over a Google surface image, or anything else for that matter.  It's a little tedious to do, however.

Some appraisal districts have software that show maps like what you are talking about but not superimposed over google photos. The one I have seen shows the individual parcels, surveys, etc however you want to use it. About a year or so ago it was about $60. Don't know if the SA Appraisal district has that mapping capability or not but you should check. They probably do.

Will someone that knows what the San Augustine County records office is like today please post.

The last time I was in it was 10 years ago.

You do know that it is in the old shopping center (next to the sheriff's office)?  I was in there last week and it had a good crowd but there is usually plenty of room to sit down.

No, but I think I know where you mean, there is or was a Dollar Store down there.

 

Thanks saved me some time.

You said "down there" so you know I'm talking about "under the hill", LOL!   Yeah, just go down the hill from the NE corner of the square.

I have traced some survey boundaries and put them over an image from Google Earth.  It's both interesting and confusing how different plats of the same area do not coincide with each other.  The boundaries on the RRC well site (referred to by 5thGenTexan), the boundaries on the TNRIS site (referred to by Johnnie Joe), the surveys done and published on RRC as the plat for a drilling application, and the visual parameters that can be obviously seen on a surface image in Google Earth -- nothing matches exactly.  I have drawn the outlines of land surveys and the plats of GU's and the boundaries don't match.  Hardly anything corresponds to visual boundaries in Google Earth.  I even tried to put two GU plats together that had a boundary line in common, and they didn't match.  The general shape is the same - i.e. at least they resemble each other, but the corners and the measurements don't.  If one is looking for some exact boundaries, that's a bit confusing.  Maybe that's why everyone seems to want "their" own survey.

I overlay Unit plats on Google Earth and generally, if it is the same operator using the same surveyor to make adjoining unit plats, they will match up pretty close and you can get a good approximation.  But adjoining units from different surveyors will usually not match up exactly.  And, I don't use TRRC GIS map except to find out where a survey is and, very rarely, to locate a well.  I use the plat coordinates to mark the surface location of the well on Google Earth and that helps in positioning the overlay plat. 

If you want exact boundary dimensions... you need a survey.  Well plats usually have a disclaimer that they are not an depicting  exact survey and tract boundaries.

 

I've also drawn some tracts out on mapping software that could probably be used for overlays but I've never tried that.

Another source - the RRC uses Tobin maps, and typically operators use them.  If you want to look into Tobin maps, here is a link http://www.p2energysolutions.com/home.  Not sure the of the cost.

Google Texas Survey boundaries in KML, or go here http://www.earthpoint.us/TexasLandSurvey.aspx

About a year ago or so I gave the Clerks office a map denoting their survey boundaries with a number of gas units on them.   If it will help you a wee bit, I've attached one that is not quite as old as the one I put at the clerks office.
