Q: What's the difference between the four data aggregation methods in the "Data Aggregation" dialog box? [ + ]
Q: What's the difference between the four data aggregation methods in the "Data Aggregation" dialog box?
A: Keep the first: Sets the field value of the resulting object to that of the first selected object. If you selected objects to union by dragging a box, the field value of the resulting object keeps the value of the object with the minimum SmID.
NUll: Specifies the field value of the resulting object to be null.
Sum: Specifies the field value of the resulting object to be the sum of the selected objects' corresponding field values.
Average: Specifies the field value of the resulting object to be the average of the selected objects' corresponding field values. If you select this option but do not select a weight field, the system will first compute the sum of the corresponding field values of the selected objects, and then divide it buy the number of the selected objects, to get the average. If you have selected a weighted field from the dropdown list, the system will compute their weighted average.[ - ]

Q: When I set the buffer radius to 5, the buffered area is unexpectedly large. How does that happen? [ + ]
Q: When I set the buffer radius to 5, the buffered area is unexpectedly large. How does that happen?
A: By default the buffer radius is in the same unit as the dataset buffered.
