Integrated Spatial Information Solutions Proposes Name Change to PlanGraphics;
Schedules April 30 Investor Conference Call


PARKER, Colo., April 24, 2002--Integrated Spatial Information Solutions, Inc.
(ISIS; OTC BB: ISSS), a supplier of e-government solutions that leverage
locational data, is asking shareholders to approve the change of the company's
name to PlanGraphics, Inc. The change is subject to the approval of shareholders
at the company's annual meeting on Tuesday, April 30, 2002 (10:00 a.m. EDT, at
the Atrium of the Treetops Building, 8181 Professional Drive, Landover, Md.)

The primary reason for the change is "to capitalize in the investment community
on the positive accomplishments and national recognition that industry leading
PlanGraphics enjoys in the geographic information systems (GIS) marketplace,"
said John Antenucci, president of ISIS. PlanGraphics is the sole operating
subsidiary of ISIS. "We have moved aggressively into the GIS industry through
PlanGraphics, and our business has increased significantly," said Mr. Antenucci,
"and we intend to capitalize and build on the `brand awareness' of PlanGraphics
that exists throughout the industry."

PlanGraphics continues to broaden its spatial IT consulting and
system-integration business to include e-government and "homeland security"
solutions. For example, the company is presently designing and building a GIS
data warehouse for New York City's Department of Information Technology and
Telecommunications, furnishing access and applications to a wealth of city maps
and data. This project was expanded to provide round-the-clock support to the
New York City Office of Emergency Management in the aftermath of Sept. 11.

ISIS has scheduled an investor call immediately following its annual
shareholders' meeting for 11:30 a.m. EDT, Tuesday, April 30, presented by Gary
Murray, chairman, and John Antenucci, president. The call will be Webcast live,
and may be accessed for a period of 60 days by logging onto at

Webcast will require use of Windows Media Player as a plug-in to Web browsers

The conference call may contain certain forward-looking statements that describe
the future business, prospects, actions and possible results of the company
which constitute forward-looking statements in the "safe harbor" provisions of
the Private Securities Litigation Reform Act of 1995.
