Item 8.01.    Other Events

On November 19, 2004 Analytical Surveys, (the "Company")issued a press release commenting on recent trading activity in its common stock and the conversion of the Company's senior secured convertible promissory note held by Tonga Partners, L.P. The Company reiterated that it is unaware of any business reason for the recent unusual trading activity in the Company's stock. Based on reports filed by Tonga since its conversion of the note, the Company has learned that Tonga has sold its shares of common stock in the Company and no longer holds any Company shares. Prior to the recent unusual trading activity, the Company had been negotiating with Tonga to buy the note at a discount and remove the convertibility feature of the note except in the event of default. The Company believes that the unexpected substantial trading activity caused Tonga to revisit its ability to liquidate the underlying shares of common stock and elect to convert the note into shares of the Company's common stock. Upon the sale of all of its the Company's shares, Tonga has relinquished its right to appoint directors of the Company. A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K.
