map error?

checking the INEGI 50K maps
came across "Mision Santa Agueda"
what's your opinion David?
H12C83

found mistakes on pretty much every topo so far
maybe this is one of them

Yes, sadly the government cartographers in D.F. just don't seem to have the passion for details or accuracy!

The site is on the Baja Almanac maps, but without the word 'Mision' with it. The 2003 Almanac has a church symbol for it, but the 2009 Almanac just back square. It seems to be on a eastern branch of El Camino Real, but east of the one Harry Crosby shows on his map.

Neal Johns was the first to discuss this with me I think... he tried to find a way to get his Tacoma in there to investigate, or wanted to. Perhaps with Bing or Google Earth?

EDIT: as for mission connection, not a mission and not a published visita, but it could have been... I will go over my Jesuit writings again, but I don't recall any mention of it... stay tuned!

Google only has blurry images for that area

Bing has newer and better images...

Here is Santa Agueda per the map, on Bing, and it is a tinaja where the trail meets the arroyo (see a short switch back to the left of the tinaja). Oh, the older Baja Topo Atlas has Mision with the name.

GPS is N28 10' 7.7", W113 4' 11.4" (don't know how to change to decimal minutes from minutes and seconds on Bing)




Now, here is a higher view, you can see the dry lake bed at the top of the image. The tinaja is still in the center with the cross hair over it...

map makers place errors in random places so they can easily tell if someone is infringing on their copyright, copying their maps and selling them as their own.

We are talking government topo maps in this case, paid for by the taxpayers, so I am not sure if that is the same as private (for profit) made maps? Still, the errors are there... On the Mexican topos (and in the Almanac made from them) many, many errors... wrong names for arroyos, bays, points, etc.
