RDBMS_GISアドベントカレンダーも4年目になりました！
PostGIS（PostgreSQL) やMySQLをはじめとする各種RDBMSを使っての「データベースでの空間情報(GIS)」について、約1ヶ月間、語りつくしましょう。

　こまかい技術情報から、ちょっと試してみた話題、そしてポエムっぽいGIS関連話まで、ぜひご参加ください。RDBMSのGIS機能を使った事例も増えてきているようですので、ご紹介いかがですか。どんな技術を使っているのか、色々な話を伺いたいです。
　また、「RDBMS」と名乗っていますが、"R"の部分はあまり厳密に捉えなくて良いので、データベースにGISデータを格納、活用するお話をぜひお寄せください。
