I am clipping and saving an IMG file (created in ERDAS Imagine's MosaicPro tool) using a model in ArcCatalog 10.4. When displayed in ArcCatalog or when opened in Arc 10.4 its symbology is set to "unique values".

How can I change the system defaults so that the model will write the file so that it is "stretched" when opened, preferably with no default stretch applied?

  • The default stretch of 'unique values' is because your raster is an integer, if you save as float you should get the stretched renderer by default. – Michael Stimson Mar 29 '17 at 2:14
  • Thank you. How do I do that? The model is running from ArcCatalog, I have just set Custom Rendering Defaults but I can't find any reference to "integer" or "float". – Ozplanman Mar 31 '17 at 2:04
  • Use the spatial analyst tool Float resources.arcgis.com/en/help/main/10.2/index.html#//… to write the output as floating point. Without knowing more about the model it's hard to say where to use this tool in it. – Michael Stimson Mar 31 '17 at 2:07
  • @MichaelMiles-Stimson thanks very much. Will investigate. – Ozplanman Mar 31 '17 at 5:17

As commented by @MichaelMiles-Stimson it seems likely that:

The default stretch of 'unique values' is because your raster is an integer, if you save as float you should get the stretched renderer by default.
