GeoTiff Para Um Shapefile

Question

<\/HEAD>Oi,<\/P> <\/P> Eu tenho um arquivo GeoTiff de 4 bandas que representa o grau de vegetação em uma área, com um tamanho de célula de 30x30. Quero convertê-lo para um shapefile para que eu possa adicioná-lo a outro shapefile (para que eu possa executar um OLS). <\/P> <\/P> Mas eu não sei como converter tif para shp. Eu tentei ler fóruns online, mas continuo travando. Qualquer ajuda ou conselho seria apreciado. <\/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.
