Abstract: Modern society is in an era of information explosion, and digital information is growing at an unprecedented rate. Under poor network environment, geographic information application service system is faced with limited storage capacity. In addition, considering that geospatial data are stored in a variety of computer platforms, it is urgent to study and design a unified data storage standard to solve the inconsistency of spatial data format among the different GIS platforms. Therefore, this study is based on the GeoPackage (GPKG) data container storage standards and Qt5.2.0+VS2010. GeoPackage format checking software was designed to check the format of GeoPackage files, which provides help and support to the standardization of GIS data format. Specifically, the software quickly realized the core functions, optional features and registration optional functions, and can be able to output details of the inspection results, which could effectively solve the problem of inconsistent data format among the different GIS platform and GIS application and simplify the steps of data conversion.

Key words: GeoPackage format checking software, GeoPackage, SQLite, Qt
