Help with RASTER Calculator!

AlexandraHestilow — Mon, 21 Nov 2011 15:58:33 GMT

I am taking a class and they are asking me to create a binary raster from a distance surface that I just created suck that pixels within 2-4 miles distance to the existing police stations and storefronts will be coded 1 and zero otherwise. I need to also convert the units from mile to meter in the raster calculator.

I am not the best at raster calculator so can anyone help me on how to write this out?

Thanks,

Alex

Homework requires you show what you have tried so far. Also, specify the version of ArcMap.

I just don't know how to write out the code properly. I had to do this previously and it worked but now I have to convert miles to meters also and I have no idea how to write the code out.

Earlier I had to: create a binary raster from a crime density surface such that the pixels with a crime density higher than 15 will be coded 1 and zero other wise:

CON(densityraster > 15, 1, 0)

I am just lost on how to write the new one including telling it to convert miles to meters
