店舗キャッチメント境界の抽出

<\/HEAD>

コミュニティの皆さん、こんにちは、<\/P>

 <\/P>

Primary属性が0％以上で変動する100以上のキャッチメント（ポリゴン）のシェープファイルを抽出しました。<\/P>

 <\/P>

Primary属性の合計が少なくとも75％に等しい各ポリゴンの境界を抽出したいと考えています。 <\/P>

 <\/P>

100以上の場所でこれを行う方法について何か提案はありますか。<\/P>

 <\/P>

注意 - 手動抽出プロセスは承知しています。また、現時点ではNetwork analyst extensionは持っていません。<\/P>

ありがとうございます。<\/P>

Hi Dennis,

Forgive the lack of clarity. Let me put it this way. I have a catchment (or a polygon) made up of several smaller polygons. It is classified based on an attribute (lets say sales) from 0% to max, where the aggregate of the attribute values for different record equals to 100%. 

Now I want to extract the catchment (boundary), such that the internal polygons having sales of max to min are selected and their aggregate equals to 75-80%. [This is just a condition]. This will give me a prominent catchment boundary instead of vast one. 

I can do it manually by going to attribute table and select the attribute (lets say sales) of records equaling to 75-80%. But I want to automate this as I have to do it for 100+ shape files.

Thank you for the time and consideration.

NOTE - Each shapefile needs to be done individually, cannot merge it.

Regards,

Anudeep.
