Abstract: According to the spatial characteristics of radar data, the radar projection plane space and
the radar stereo space are divided into two kinds of radar space to construct the lattice model, which
provides model support for the multidimensional representation and analysis of meteorological radar
information. Combining the surface information of the research area, the visualization development
package VTK is used to realize the visual expression of the lattice model. Under the support of the
model, the visual expression of integrated terrestrial information is no longer limited to the
two-dimensional form. The three-dimensional representation can display the radar details more
comprehensively, which is helpful for the meteorological personnel to study and analyze the
structural characteristics of radar echo.

Key words: lattice model, visualization toolkit, radar data, visualization
