Mr. John C. Cavalier, Chairman
Mapinfo Corp. ("MAPS")
One Global View
Troy, NY 12180

Dear Mr. Cavalier,

Cannell Capital LLC, ("Cannell") serving as investment adviser and investment
sub-adviser to several private investment funds and partnerships, is amending
its reporting requirements to reflect a more active stance with respect to
Mapinfo Corp. ("MAPS")

Cannell would like to congratulate MAPS on its strategy, execution and
stewardship of shareholder assets. Our concern and belief is,
however, that given the low relative valuation of MAPS combined with the
current high costs of being publicly held, a compelling case can be made to
amortize the assets of MAPS over a larger infrastructure such as that enjoyed
by Oracle, Business Objects S.A., Google, SAP AG, Microstrategy or IBM.

In this regard we would encourage MAPS to interview some competent agents, if
any exist, in order to solicit such a transaction to produce the highest
economic and tax favorable benefit to the shareholders of MAPS.

Sincerely,


J. Carlo Cannell
