Question About Euclidean Distance Calculator

[AimeeRoach]

I'm attempting to use the Euclidean distance tool in spatial analyst tools to calculate the distance from a polygon feature class. The problem I'm having is that even when I specify a maximum distance for the tool to calculate distance until, it still only creates output for the default maximum distance (to the extent of the input feature class layer), which in this case is around 5m or so. However, I want it to calculate distance much further out than that. Is there some simple step I'm missing to make the software recognize the maximum distance that I input and specify? Any suggestions would be greatly appreciated.

If you're setting a max distance larger than the extent of the inputs, you need to set the extent of the output explicitly in the environment settings when running the tool.

Best,

Thanks very much, problem solved!

I have one other question, regarding the raster calculator. I'm using the raster calculator to input a regression equation that I've created from my data, using the output I created with the euclidean distance calculator as the x value for the equation. However it predicts unrealistic values outside the range of what I know is possible for the variable I'm measuring. I'm wondering if there's a way that I can limit the output of the output from the raster calculator to only predict within values I know are possible? For instance limit the prediction to within -4 to 1, rather than allowing the calculator to predict values of up to -16, etc.
