He's not claiming to provide "regulated professional services", in fact quite the opposite. If the California statute or regulation in question says that it is, it's wildly overbroad. I recently used AcreValue.com to find the rough location of some remote timberland my late mother owned. I've never been there, nor has any other living member of my family. My niece is in the area, and wanted to go out and take a look at it (mainly to make sure no one has set up a meth lab out there or something). The map from AcreValue is perfectly adequate to navigate her to the area. Now, we would be foolish to use that map in lieu of a professional surveyor if we were planning on building a wall around it or something, but we're not doing that, or anything like it. I'm guessing from what people are saying that is that the AcreValue site is also illegal under California law. Edit: I can tell that it's adequate because I also looked at the official county plat map, and can see that the AV map is congruent with the plat map, in respect to the (dirt) roads and geographic features of the surrounding area. I don't (and shouldn't) need to hire a surveyor for this.
