[0011] (5) On-site collection and entry: after the data collection function is enabled, the surveyor takes a field photo through a photo unit integrated in the offline map operation interface, and then enters land attribute information through a data entry unit integrated in the offline map operation interface.

[0012] (6) integrity check: the entered land attribute information and the captured field photos are checked for integrity;

[0013] (7) data saving: only after passing the integrity check, the land attribute information and the field photos are saved in association;

[0014] (8) data synchronization: the saved data is synchronized to the system database.

[0015] Preferably, in step (7), the land attribute information is synthesized as a watermark on the field photos by a photo synthesis module.

[0027] The integrity check module is used to check the entered data;

[0028] The data storage and synchronization module is configured to save the data and synchronize the data with the data module after the verification.
