Abstract

Embodiments of the invention provide an ocean-land geographic information element encoding method and apparatus. The method comprises the steps of obtaining a land code of a geographic element; obtaining an ocean geographic object sequence code of the geographic element; and combining the land code with the ocean geographic object sequence code according to a preset rule. Therefore, unified expression of land-ocean basic geographic information data is realized and a user can obtain an original source of data subjected to unified encoding through code information.

Description

technical field [0001] The invention belongs to the field of geographic information system data processing, and in particular relates to a coding method and device for sea and land geographic information elements. Background technique [0002] The data fusion of sea and land vector maps can integrate the information of vector sea charts and vector land maps, so it can eliminate the single information and space limitations brought by a single vector sea map or a single vector land map data, and obtain rich information and high quality. Higher information can better meet people's application needs. With the application of geographic information system more and more widely, people's demand for geospatial vector data is more and more urgent, and sea and land vector data often have differences in spatial reference, semantic coding, storage format, etc., which makes sea and land vector data The integration and fusion of map data has been widely used. [0003] Spatial data fusion...
