HUNTSVILLE, Ala. August 29, 2002 - Intergraph Mapping and GIS Solutions today
announced that GeoMedia(R) Grid 5.0, an advanced, fully integrated grid analysis
toolkit for GeoMedia, is now shipping worldwide. Built as a collaborative effort
with Keigan Systems, the new product combines the strengths of GeoMedia's vector
GIS capabilities and the power of grid analysis tools within a single GIS
environment. An integrated GIS environment provides the most efficient setting to
explore spatial relationships dynamically and enables mapping, GIS, and IT
professionals to produce more insightful results as they compare, combine, and
relate vector and grid data. In addition, GeoMedia Grid's capability to move
seamlessly from a vector to grid environment and back to vector allows users to
easily apply the analysis and modeling method that is best suited to any given
stage of an analysis workflow in applications such as crime mapping, incident
mapping, business planning, hydrologic engineering, spill mapping, habitat
modeling, least cost routing, troop movement, corridor mapping, field of fire
mapping, and tower locating.

Featuring leading-edge technologies and an expanded set of grid tools, Intergraph's
GeoMedia Grid is ideal for solving geospatial analysis problems for hot spot
(spatial cluster) analysis, flow characterization analysis, surface analysis,
viewshed analysis, relationship modeling, and data visualization. Key new features
available in GeoMedia Grid 5.0 include:

-- Conversion between grid and vector features
-- Grid/raster reprojection and rubbersheeting
-- Grid overlay analysis
-- Surface creation and analysis functions
-- Improved interpolation utilities
-- Zonal, focal, and regional features for measurement, characterization, and
statistics
-- 3D visualization
-- Grid classification facilities
-- Grid data editing
-- Hydrological data processing (watershed delineation and stream segmentation)
-- Support for all standard formats -- DEM DTED, remote sensory imagery, and
scanned images

Developers can use GeoMedia Grid COM-compliant objects to enhance existing
applications with custom commands or to create spatial analysis solutions for
specific applications and users groups. Intergraph's GeoMedia Grid enables
developers to:

-- Build a customized raster/vector GIS
-- Create push-button solutions for clients
-- Add map viewing and manipulation facilities to existing applications
-- Combine grid tools with GeoMedia functionality
-- Build tailored spatial models

Because GeoMedia Grid objects can be used in rapid application development
environments, such as Microsoft Visual Basic(R) and C++(R), grid processes can be
effectively and tightly integrated into day-to-day operations. The new product also
comes with an extensive MS HTML Help feature that defines the methods and
properties of each object and control.
"There has never been more powerful grid data modeling and visualization technology
integrated into a single GIS environment," says Pete Crosbie, GeoMedia Grid product
manager, Intergraph Mapping and GIS Solutions. "This combination of the
best-in-class grid software and state-of-the-art vector tools gives professionals a
more intuitive means to solve the most complex geospatial problems. GeoMedia Grid
is another example of Intergraph's commitment to deliver industry-leading products
with the flexibility, scalability, and interoperability required in today's
enterprise."
