How to force the classification to follow particular values? When doing the classification for raster, the classification starts from the minimum cell value. For the integrity of the work, we need to set the classification to be valid in all cases depending on the workflow that we have. For example, how to make the classification of the raster follow the values in the table below: [ATTACH=CONFIG]14640[/ATTACH] Please, have a look on the screenshot and attached data [ATTACH=CONFIG]14638[/ATTACH], [ATTACH=CONFIG]14639[/ATTACH] Thank you for the help, Best Jamal

How the ???transformation method??? is different from ???resample type???? I???m wondering based on which equations the ArcGIS perform sthe transformation. What is meant by ???adjust??? that exists as a transformation method (screenshot below)? [ATTACH=CONFIG]14573[/ATTACH], [ATTACH=CONFIG]14574[/ATTACH] What is the effect of the ???transformation method??? and ???resample type??? on the produced georeferenced raster? Thank you for the help, Best Jamal

Here, try this: SetNull(("StreamOrder"==1) & ( Lookup("StreamLink","count") <= 250), "StreamLink") Many thanks for the help. The problem wouldn�??t be resolved without the great help you offered. Best Jamal

Hi Jamal, Dot notation does not work in the 10.0 Raster Calculator. You will need to use the Lookup function. Something like this: SetNull(Lookup("Raster","COUNT") <= 250, "Raster" ) Using raster attribute other than 'value' in map algebra Lookup function in v10.0 Map Algebra: implementing dot notation in v10.0? Thank you for the answer Timothy. Sounds it is not working with the lookup tool! Please, have a look on the screenshot below.

What is wrong with this syntax when using the Raster Calculator tool? (9.3) I'm wondering what might be the correct syntax when using the ArcGIS 10 Raster Calculator tool compared to the old 9.3 Single Output Map Algebra tool? Two screenshots are attached. The first attachment shows what was correct when using the ArcGIS 9.3 Single Output Map Algebra tool The second attachment shows how I tried to do the same using the ArcGIS 10 Raster Calculator tool which did not work! What might be the correct syntax to such expression when using the Raster Calculator tool? Thank you for the help Best Jamal (Original post date 5/17/2012, edited to fix garbled formatting from old forums conversion by Curtis Price 5/18/2015)
