[Abstract]:In the face of increasing spatial data and poor network environment, GIS is faced with the challenge of limited storage capacity and closed geospatial data format. However, many existing geospatial data storage depend on the platform, and need to overcome the problems brought by cross-platform. It is urgent to study and design uniform data storage standards to solve the inconsistent spatial data format. The data conversion process of different GIS platforms is complex. Considering the difference of data format between different GIS platforms and GIS applications, this study is based on Geo Package (GPKG) data container storage standard, Qt 5.2.0 VS2010 development platform and C programming language. The checking software of GIS data storage format is developed through three-tier architecture programming mode to solve the problem of inconsistent data format. By using batch database query, the software quickly realizes checking of more than 100 function file formats, such as core function item, optional function item, registration and extension function, and outputs detailed checking results. It can provide support and help for the standardization of GIS data format storage. It can effectively solve the problem of format inconsistency in data sharing between different GIS platforms and different GIS applications, and simplify the steps of data conversion.
