pythonコード（多変量変数を用いる場合）

フィールド演算で「コードブロック」として入力する内容（def で始まる一連の記述）には、Python の文法に従って関数を定義します。お知らせ頂いた FAQ に記載の例では、Reclass という名前の関数を定義しており、ひとつの引数（関数への入力パラメータ：temperature）を受け取っています。

関数が受け取ることのできる引数の数は制限されません。たとえば気温の他に降水量も必要な場合は、関数 Reclass の定義を修正し、def Reclass(temperature, precip): などとすることで 2 つの引数を受け取れるようになります。

もちろん、関数を呼び出す側、現在 Reclass( !TempAug15! ) となっている箇所も、Reclass( !TempAug15!, !Precipitation! ) のように修正が必要です。

あとは、関数 Reclass の中で 2 つの変数を使ったロジックを書いていく、ということになります。この関数の return する値が、フィールド演算で最終的にフィールドに設定される値となりますので、2 つの変数を使ってご希望の文字列を return するようにしてください。

関数内部のロジックなど、実装方法については ArcGIS 特有の使い方というよりも、プログラミング言語 Python の使い方になります。Python の学習に関しては、優れたサイトなどが多数あるようですので、一通り基礎的な部分を習得されますと ArcGIS での活用に役立つものと思います。

また、ArcGIS のフィールド演算における Python の記述や、arcpy と呼ばれる ArcGIS 特有の Python モジュールの使い方などでご不明点がある場合には、別途有償の「開発者サポート」サービスにて承っておりますので、ご検討頂ければと思います。

とあるポイントに対してラインまでの距離が一番短い場所を抽出

２通りの方法がある。
どちらも最短距離が算出でき、その他の点が異なる。

○ ArcToolbox の [最近接（Near）] ツール　←何故か上手いいかない、下段の方式を利用する方がベター
ArcToolbox → [解析 ツール] → [近接] → [最近接（Near）]

このツールによって、各ポイントに対して、ライン シェープファイルのラインフィーチャの中で、最短距離、最短のラインフィーチャの ID、ライン フィーチャ上で最も近い位置のXY座標、角度 を算出し、ポイント フィーチャの属性に付与できる。

※ [最近接（Near）] ツールは入力データを上書きしてしまうので、実行前に必ずデータのバックアップを行う必要がある。

○ ArcToolbox の [空間結合（Spatial Join）] ツール
ArcToolbox → [解析 ツール] → [オーバーレイ] → [空間結合（Spatial Join）]

ツールのパラメーターとして、以下を設定。

　ターゲット フィーチャ：家屋情報のポイント フィーチャクラス
　結合フィーチャ：ライン フィーチャクラス
　出力フィーチャクラス：ツールが結果として新規作成するフィーチャクラスを指定します。
　結合方法：JOIN_ONE_TO_ONE
　マッチ オプション：CLOSEST
　検索範囲：適当な数値を入力します。各ポイントに対して、この項目に入力された範囲のラインを検索します（入力不要）。
　距離フィールド名：結果フィーチャクラスの距離フィールド名を指定します（入力必須）。

このツールの処理により、各ポイントに対して、ライン シェープファイルのラインフィーチャの中で、最短距離と、最短のラインフィーチャの IDを算出。結果は新しく出力されたポイント フィーチャの属性に付与される。
