Integration
Function Description
Integration refers to snapping the nodes within the tolerance range together, that is, treating the objects within the tolerance range as the same object or overlapping objects. It can be used to deal with gaps and overlaps between common edges of objects.
- Integration applies to point, line, and region datasets.
- Integration will change the source data. To preserve the source data, it is recommended to back up the data in advance.
- During integration, nodes that are snapped together will be modified to the same two-dimensional coordinates.
- During overlay analysis, if you choose not to perform data topology preprocessing, you can perform Integration or Topology Preprocessing in advance to ensure that the data topology meets overlay analysis requirements.

Parameter Description
The dissolve result is shown in the following figure:
- Source Dataset: Sets the dataset that requires data integration.
- Precision-level Array: Sets the precision-level array for integrating datasets. The smaller the value in the precision array, the higher the accuracy and better data quality of the corresponding dataset. During point snapping, points in lower-precision datasets will be snapped to the positions of points in higher-precision datasets. The precision-level array must have the same number of elements and correspond one-to-one with the collection of datasets for data integration.
- Integration Tolerance: Sets the tolerance value for integration. It is a distance value, meaning that within this range, all nodes or (and) lines are considered coincident or identical. For example, if the distance between a node of a line object and a node of another line object is within the tolerance range, the two nodes are considered coincident; if the distance between a node of a line object and a point object is within the tolerance range, the point is considered on the line. Integration will be performed when the distance between nodes or (and) lines is less than the tolerance value.
- Unit: Selects the tolerance unit.
