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 alter 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 have the same two-dimensional coordinates.
- During overlay analysis, if you choose not to perform data topology preprocessing, you can perform Integrate or Topology Preprocessing in advance to ensure that the data topology meets the requirements of overlay analysis.

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