I have 300 polygons in a single shapefile, I want merge some polygons together, when I merge two polygons the attribute does not come total count of two polygons,

What I need is, when I merge two polygon the attribute value has to add together and the total value has to come in merged polygon attribute.

    Could you please reword this question. Are you talking about creating single part features or dissolving boundaries?

    What do you mean by "total value"?

    If I understood you well,you wish to merge the polygons by selecting them in Edit mode and then merge them. Am I correct?

  • Alexandre Neto is right, when i Merge two polygon in Edit mode, the polygons are merging but the attribute does not calculate.

Use the dissolve tool in the toolbox: Datamanagement > Generalisation .

You can dissolve 2 fields with a common value with variable: dissolve_field

You can set the field you want to summerize in the variable: statistics_fields
