I'd go for the irrigation canals too. To me the grid looks like some kind of giant chinese character. Somebody can read chinese?

[OSM-talk] Error in Google-Maps
Hello, please don't shoot me if I'm absolutely wrong at this place. I want to ask what is to be done if a strange error in Google-Maps appears. This map (like OSM) should also be free of strange mistakes. Does anybody know, who (in person) is responsible for the information provided by Google-Maps. (I think even OSM is not absolutely correct in this area - I have to check it this weekend).

It is perfectly normal for slight differences in the data, where the streets are off set.

That's really ridiculous - the same situation appeared while I was mapping Sousse/Tunisia - the complete Google-information looked like: Let's draw something that looks like some streets that meet in one point (hopefully the center of a city) but there's no time to care for reality.

Re: [OSM-talk] Error in Google-Maps
Never *attribute* to *malice* that which can be adequately explained by stupidity Malice : Google wouldn't tarnish their brand by knowingly sell incorrect data. Stupidity : Looking at South Africa, they clearly used some AI type software to convert aerial imagery into vector data and it didn't work very well. Perhaps their Brazilian contact used the wrong projection.
