GeoTiff を Shapefile に変換する

Question

<\/HEAD>こんにちは、<\/P> <\/P> 私は、30x30 のセルサイズで地域の植生度を表す4バンドの GeoTiff ファイルを持っています。これを shapefile に変換して、別の shapefile に追加したい（OLS を実行できるように）と思っています。<\/P> <\/P> しかし、tif を shp に変換する方法がわかりません。オンラインのフォーラムを読んでみましたが、うまくいきませんでした。何か助けやアドバイスをいただけるとありがたいです。<\/P><\/BODY><\/HTML>

I converted your discussion to a question and moved it to Imagery and Remote Sensing‌

Both might get you more responses.  Also tagging Managing Data‌

I agree with Dan that simplifying might be in order, but converting to a file GDB polygon layer before a shape file.  It might offer more flexibility and options.  Once you have it ready, then export to a shape.  Shapes may have other restrictions.

As to converting, How Polygon To Raster works—Help | ArcGIS Desktop   might be a good starting point.

That will never convert to a shapefile because of the complexity of the image. It needs to be far more generalized and cleaned up.  Every speckle on the image that is slightly different from its neighbor will attempt to become a polygon. That image need further reclassification to reduce the number of areas to a manageable size.
