Conjuntos de Dados Mosaico e Métodos de Compressão Permitidos

MarieCline_Delgado

Eu tenho um conjunto de dados mosaico onde o Método de Compressão Permitido está configurado para permitir apenas LZ77. No entanto, quando eu Analiso o mosaico, uma mensagem é retornada dizendo "Os métodos de compressão mais frequentemente usados para pixels referenciados pelo conjunto de dados mosaico são: Nenhum 100% e LZ77 0%. Captura de tela anexada.<\/P>

Ou eu estou entendendo mal a funcionalidade dos Métodos de Compressão Permitidos ou a propriedade não tem efeito real no conjunto de dados mosaico. Alguém aí no mundo Esri tem algum conhecimento que possa contribuir para me ajudar? <\/P>

Let me guess, you just updated to the latest version of Pro? 3.2.1

I've noticed some of the same issues when I did the test with the mosaic dataset. I tried to build stats on the test mosaic dataset after I made it and it wouldn't work. But then I remade the mosaic dataset from scratch and built it in that dialog, it calculated them just fine.

Interesting. Statistics is another problem I have apparently. I have calculated statistics and built pyramids, but the analysis continues to report that the mosaic does not have either.

I have quite a few mosaic datasets that I work with regularly, but I don't recall this ever being an issue. I'm so stumped.

I tried a few tests on my end to see what would happen with a TIFF file I have. Same results...says 'None' even though I set it to other compression methods in a new mosaic dataset.

I thought maybe if you didn't have statistics for the file it would return 'None', but either way it gave me the same result.

Hi, I have tried other methods, including JPEG, and the Analysis always returns with 'None' as 100%.

I have radar data in the mosaic. NetCDF format.

Do you have imagery in your mosaic dataset? And what format is it?

Have you tried other compression settings, like JPEG?
