__NOTOC__
==Data Sources==
;What are the data sources?
:As a general rule, we do not disclose our data sources. Our MAK data is built off of a combination of different sources including governmental, county level, and other providers.

==Data Quality Guarantees==
;Are there any type of guarantees on data quality or quality assurances that can be put into place?
:We are very confident in the coverage provided by the MAK table and we can give counts if there are any specific queries. If you have a specific protection you would want, we can look into it and consider some type of guarantee. We have not had any demands for guarantees in the past so it is not a regular part of our offering.

==Who Uses MAT?==
;Who uses MAT?
:County Departments could use MAT for:
:*Better route planning and reduced response times for first responders
:*More efficient waste collection and utilities management
:*Improved zoning, land use and surveying/mapping applications
:*More accurate risk assessment for natural hazards

==Address Types==
;Does this field only designate residential/business/unknown, or are there other values?
:The RBDI field only indicates Residential or Business. However we also have the Address Type Indicator which gives more information about the address.

:You can find a full list of the codes and their meaning here:
:*[[Result Code Details#Melissa Address Table|Melissa Address Table Result Codes]]

==Address Type Attribute Assignation==
;How is this attribute assigned, and what is the confidence level in its accuracy?
:We use multiple sources to verify these attributes. The data goes though different levels of verification and are updated monthly.

==Multi-Level Structure Coordinate Handling==
;In the case of multi-level structures, are the latitude and longitude coordinates stacked for all addresses/sub addresses within each structure?
:86% of the MAT data is coded at rooftop level and 14% the Record is coded to interpolated rooftop level. (If it is interpolated: it is likely to be on the street, off of the building.)

:We have a Base MAK ID which refers to the parent for suites, apartments, and PO Boxes.
:*All the address will have latitude and longitude coordinates.
:*If there 10 addresses in the building all the address in the building with have same latitude and longitude.
:*If it is rooftop it is most likely a parcel centroid. The shape and size of the parcel will determine skew of the point from the rooftop of the building.

==Latitude/Longitude Accuracy==
;The Latitude and Longitude accuracy is listed as rooftop level, but how many decimal places is this on the coordinates?
:The accuracy is six digits after the decimal on the coordinates

==US Address Point Format and Pricing==
