NTOA does not make its model policies available to the public. Even LE has to pay money for some of the documents, although there is an exchange section. They do this because many of the policies and document contain operationally sensitive information. While it is not secret information in the sense that "classified" government documents are (and are protected from disclosure by criminal penalties), these types of information are generally not disclosed for the safety of the officers who have to use these tactics and policies.
Just as an example, lets say your policy said that your team would never serve a warrant on a house with guard dogs (which of course isn't the case, but I am trying to come up with an example that doesn't make me violate OUR policy by releasing sensitive information). If that became common knowledge, then every bad guy in town would get a couple of guard dogs and you could never serve any warrants.
As far as making sure you get the right location, that is usually a part of the planning process, which will probably be defined in policy. Generally, more than one person, particularly the persons who lead the mission, will physically observe the location prior to the mission. One of the persons responsible for the warrant will be involved in the planning process, and other officers who have been there (lets say they took a theft report there two years ago or handled a disturbance) will be spoken with before the mission to get their insights on the floor plan, environmental hazards and so forth. I even worked one where one of our officer had actually lived in a rental property that we were serving a warrant on, and gave a detailed floor plan. All of these procedures serve to double-and triple-check the target location to make sure it is the right one, and that the persons doing the mission know where they are going. Everyone involved will get a chance to see pictures or public available surveys. All available information will be given to the team in a detailed briefing prior to execution of the mission. I really can't go into further details without (again) getting into stuff I shouldn't talk about.
Additionally, there are also very strict requirements (at least in some states) for describing the property to be searched in exacting detail in the probable cause affidavit (since the legislators did this, it may be proof that they are not always morons). This will generally include:
1) The exact physical address, or approximate and map coordinates if no address exists;
2) Description of the building to include color, size, number of floors, material constructed from, windows, location of doors, gargaes and anything else that distinguishes it from the house next door;
3) The owner of the house or property or the primary and secondary lessees;
4) Any other known persons who have legal access to the property;
5) Vehicles on the property.
Any professional tactical unit will do all of these things, and more, and probably has them written into policy, procedure, unit plans or has it otherwise ccovered. In fact, for liability reasons, they had BETTER have it written down and had better go by it every time, because agencies get sued all of the time when they haven't done anything wrong. ANy professional tactical will do all of these things and more. An unprofessional unit will not, and I think that we are all agreed that unprofessional units are a problem.
