Split

Function Description

SuperMap iDesktopX supports the Dataset splitting function, which supports splitting data into multiple Datasets according to field attribute values, reduces the complex and time-consuming operations of large data classification, and improves the efficiency of Data Processing.

Application scenario

When Source Data contains multiple attribute variables, but Source Data may be split into different Datasets as required in practical applications, the Dataset splitting function can be used to quickly classify data according to Object Properties. It can also be used for data distribution processing based on attribute categories. For example:

Data is split according to the scope of administrative divisions, which can be used for statistical mapping of Zonal Data.
Divide Layer Bounds according to Map Range to facilitate the distribution of data according to Map Range.

Function entrance

Data tab-> Data Processing-> Vector-> Split.
Toolbox-> Data Processing-> Vector-> Split.

Parameter Description

Source data: Select Datasource and the Dataset to be split.
Split field: Select a split field to split according to the attribute value of the field.
Result: Set the Datasource and Dataset Name stored in the Result Data. The Result Dataset is named "result _ Splited" "by default.

Hint:

According to the attribute category of the split field, Result Data will generate the Dataset with the corresponding number of categories. For example, if the Dataset is split according to the provincial administrative divisions, 34 Result Datasets will be obtained, and each provincial region will have an independent Dataset.

Application example

Case description

SuperMap Sample Data SampleData \ AnalyticalMap \ HeatMap \ heatMap. Udbx Datasource, The Culture Service _ p Point Dataset contains the data of the national cultural and educational institutions, and the data volume is huge. Now the institutions are divided into different Datasets according to their categories for classified storage and use.

Main operation steps

Click the Split button in the Data tab-> Data Processing group-> Vector category.
Select "Culture Service _ P" Dataset "in the popup split window, and select" Type "in the Split Field.
Set Result DatasourceDataset and click Execute to get the split result.
