As one or more embodiments, the updated data and the background data are compared and analyzed, and the specific comparison rule is as follows:
1) The data comparison is carried out between entities belonging to the same ground object in the front and back data;
the ground object judging rule is that the ground object classifying code attribute items are arranged in the basic geographic entity data, and if the attribute values are the same, the ground object classifying code attribute items are considered to be the same ground object.
2) Adding an update type field for the updated data to store the change type of the entity;
the update type field is an attribute item of the geographic entity, which is used to store the change type of the entity, and what is the "field" is industry-wide.
3) According to the entity change condition, the update types are divided into three types of unchanged, modified and newly added, and the specific judgment rules are as follows:
(1) for a punctiform entity, if the coordinate difference value of the corresponding entity in the two versions of data is within a threshold range (the threshold is generally the topological tolerance allowed by the data and can be specified according to the actual condition of the data), and the attribute is unchanged (the judging rule of whether the attribute is changed is that the same name attribute of the two versions of data is compared, if the attribute values are the same, the attribute is indicated to be unchanged), the judgment is that the attribute is unchanged; if the coordinate difference value is within the threshold range, but the attribute is changed, the modification is determined; if the coordinate difference value is out of the threshold range, the coordinate difference value is determined to be newly added;

If the updated data and the background data have no intersection relation or have an intersection part, but the percentage of the area and the length of the intersection part to the area and the length of the original entity is lower than a threshold range, the new addition is determined;
(4) For the unchanged or modified entity, if the spatial identity code of the updated entity is null or inconsistent with the entity corresponding to the background data, the spatial identity code of the background data entity is given to the updated entity; and for the newly added entity, re-coding the entity according to the basic geographic entity space identity coding calculation rule.
