Quality of raster data

AnzhelikaKamza3 — Wed, 15 Jun 2016 09:08:39 GMT

Hello,

I have ArcGIS 10.3.1 version. My colleaques provide me GeoTIFF. But when I open this raster in ArcMap or ArcCatalog I can see pure quality of raster data. But in QGIS or in Photoshop etc, quality is more better?

Could you please advise with this issue&

Look forward,

Regards,

Anzhelika

Hello Dan,

thanks for your replay.

After statistic calculation raster doesn't changed, still bad quality.

In ArcMap I changed Strech type from Percent Clip to Custom and after that qualiy more better. For saving this properties I used Data Export-and fill Use Renderer, No Data as 256. Result is black square without raster. If I put No data as 0 - there is no raster.

In ArcGIS 10.0 we just used Use Rendered and finaly it was raster with good quality. Why 10.3.1 don't save properties?

regards,

Anzhelika
