map quest...


I have known for years that the property line overlay provided by The Property Owners Association of Terlingua Ranch Inc. (as well as the Brewster County Tax Assessors Office) is incorrect and has led to several instances of new owners building on someone else's property.  Rather than try to correct their maps, the get around any liability for providing this misinformation with the following disclaimer: "Our mapping programs should be used as a guide.  Only a licensed surveyor can give you the actual boundaries and GPS coordinates of your property."  By starting with correct section lines, it is fairly simple to extrapolate property lines even down to 5 acre tracts and end up with precise locations without the expense of a surveyor.  For an example, here are some selections in my area.  The top map is the incorrect POATRI/Tax office overlay on Google Earth and the bottom map is from the Texas Railroad Commission website - showing the correct section lines with corrected property lines within my section.  70,74,46,0,B

No...I chose the location because of the corrected maps.

I figured out the map discrepancy 10 years ago. This is just the first time I have posted about it.

I don't believe the old Railroad survey is correct for western side of Cedar Springs area. If you look closely it shows a lot of irregular shape sections. Of course the other overlays are also wrong. I hope the original Ranch survey maps are correct. They show hilltop elvation that matches none of the others.

Jeff - the Texas Railroad Commission section map overlay is the most accurate representation of the original Texas & St. Louis Railroad survey. It precisely matches the printed version found here. https://texashistory.unt.edu/ark:/67531/metapth492959/m1/1/

The way I understand it, Texas told the railroad companies that if they would survey West Texas that they would split the sections as payment for surveying teams. So when block (or township) 217 was surveyed the railroad got then odd sections in a checkerboard type pattern. Definition of Section = A land unit equal to one square mile (2.59 square kilometers), 640 acres, or 1/36 of a township. Your property (40 acres) is in the NW corner of the NW quadrant of section 19 of 36 sections, of block or township 217. I have property in section 27 of same block 217. W.L.Moody own the section both our property's are in. For interesting documents on how he got 164 Sections cheap.

In the block to the North East (Block 220) is mostly Nine Points Ranch. East of block 220 is where the problem is. If you look East of block 220 sections 12 and 13 - you will find section 45 and 52. Using the area calculator on overlay map, section 45 is about 556 acres and section 52 is 578 acres. They are not 640 acres, so the are incorrect. That area was surveyed by Central Texas Railroad Company in the land grab. Block 332 is full of irregular sections, It later had to be resurveyed.
