I, John C. Antenucci, certify that:

(1)  I have reviewed this amended annual report on Form 10-KSB of PlanGraphics,
     Inc. for the year ended September 30, 2006;

(2)  Based on my knowledge, this annual report does not contain any untrue
     statement of a material fact or omit to state a material fact necessary to
     make the statements made, in light of the circumstances under which such
     statements were made, not misleading with respect to the period covered by

     information included in this annual report, fairly present in all material

     the small business issuer as of, and for, the periods presented in this
     annual report;

(4)  The small business issuer's other certifying officer and I are responsible
     for establishing and maintaining disclosure controls and procedures (as
     defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the small
     business issuer and have:

     a.   designed such disclosure controls and procedures, or caused such
          disclosure controls and procedures to be designed under our
          supervision, to ensure that material information relating to the small
          business issuer, including its consolidated subsidiaries, is made
          known to us by others within those entities, particularly during the
          period in which this annual report is being prepared;

          controls and procedures and presented in this annual report our

          such evaluation; and

     c.   disclosed in this report any change in the small business issuer's
          internal control over financial reporting that occurred during the
          small business issuer's most recent fiscal quarter (the small business
          issuer's fourth fiscal quarter in the case of this annual report) that
          has materially affected, or is reasonably likely to materially affect,
          the small business issuer's internal control over financial reporting;
          and

(5)  The small business issuer's other certifying officer and I have disclosed,
     based on our most recent evaluation of internal controls over financial
     reporting, to the small business issuer's auditors and the audit committee
     of the small business issuer's board of directors (or persons performing
     the equivalent functions):
