Military geological data is an important basic data of geoscience data to study the ground characteristics of typical military activity scenarios, which is helpful to understand the dynamic change process of geographic space and provides a new perspective for the customized military geo-services. Military geological data reflects the information of underground geological structure, and standardized data processing and effective military methods are becoming an important challenge for the military application of multi-source heterogeneous geoscience data. Based on the big data characteristics of military geological data, this paper attempts to construct a standardized processing solution for military geological elements, military conversion from civilian geological data, military geological database and data analysis model indexes, and to discuss the application of military geological standard data. The research progress includes as follows: (1) There are not only big data characteristics of multi-source heterogeneity, multi-modality, high integration and complexity, but also unique data characteristics of diversified time-space-physical-chemical property, and applications characteristics of rapid-steric-instant obtaining, static-dynamic-combat support, and target reconnaissance, including of supporting terrain structure and underground space, such as the complex geological processes and internal mechanisms in military geological data. (2) The application classification of military geological elements recommends the basic metadata types of military geological data for military applications, the military conversion from civilian geological data provides the principle of first compilation, then conversion and update, the military geological database fulfills the big data analysis and utilization of data aggregation, database mapping, data management and application services, and the data analysis model indexes construct a series of quantitative impact factors with weak correlation quantitative values of a group of military geological elements in the mountainous landscape. (3) Military geological element data and its vector layer overlap analysis with geographic information data satisfies the military needs of geospatial intelligence. Standardized military geological data using GIS tools can implement the customization of military geo-services with data quantitative processing, spatial analysis and mapping, so as to support the relevant theme layers, operational scenarios and instant information by geo-support in time-critical missions. Applications with modern big data technology of intelligent extraction and integrated expression, military geological standard data should have a unified element classification, a unified spatial datum, a database preparation and a customized symbol system of thematic map data for geo-services. The research results can be used to standardize the connection between military geological data and military digital information fruits, and to provide a useful tool for battlefield environmental support of precision, informationized and intelligent analysis.
