Abstract: The grid model is the core component of strategy campaign wargame environment model and influences other behavior models. Building multi-level and multi-resolution grid models is the basis of extending strategy campaign wargame, supporting fine-grained environment models and key tactical operations. In this paper, the modeling approach and models of multi-level and multi-resolution equal longitude and latitude division for strategy campaign wargame are put forward based on the military requirements and technical requirements. Firstly, grid map is divided by using the equal latitude and longitude quadrangle. Then the coordinate system cluster of equal latitude and longitude grid and related elements are defined. Finally, an example is given. By comparing with single-resolution hexagon grid modeling approach, the advantages are analyzed. The modeling approach can support multiple-resolution of strategy campaign wargame, and meet the requirements of running efficiency and environment model for strategy campaign wargame.

Key words: strategy campaign wargame, multi-level and multi-resolution grid, wargame map, equal longitude and latitude division
