FAA Publishes MVA and MIA Charts

The FAA has published minimum vectoring altitude and minimum IFR altitude charts on its website, here (scroll to the bottom of the page for the links to each category).

e. Minimum Vectoring Altitudes (MVAs) are established for use by ATC when radar ATC is exercised. MVA charts are prepared by air traffic facilities at locations where there are numerous different minimum IFR altitudes. Each MVA chart has sectors large enough to accommodate vectoring of aircraft within the sector at the MVA. Each sector boundary is at least 3 miles from the obstruction determining the MVA. To avoid a large sector with an excessively high MVA due to an isolated prominent obstruction, the obstruction may be enclosed in a buffer area whose boundaries are at least 3 miles from the obstruction. This is done to facilitate vectoring around the obstruction. (AIM 5−4−5)

The charts are PDFs, sorted alphabetically by facility.

Note the disclaimers on the main page:

The Federal Aviation Administration (FAA) Minimum Vectoring Altitude (MVA) charts and Minimum IFR Altitude (MIA) charts are being made available on this website in PDF format for users to identify the sector designs and minimum altitudes on charts used by Air Traffic Control. These charts are not geo-referenced and are not to be used for navigation. In the next two years, as Air Traffic Facilities update current MVA and MIA charts, they will be made available in AIXM 5.1 format.
