Some variant of the examples there.
Basically if the slope is <=100% return the slope value otherwise some other value like -1 or even SetNull
Con(Raster("slope") <= 100, "slope", -1)
Dan is correct in how to convert this, however this may also be a mis-understanding of the percentage slope.
This is rise/run *100, meaning a 100% slope is 45 degrees, and a 330% slope is 73 degrees.
Yes 330% is 73 degrees, now I'm interested in what to do, get a road slope of 0-100% because my task requires a road slope of 0-2, 2-10, 10-30,> 30%
The easiest way is to symbolise the data in the classes you need, then drag that layer into the Reclassify tool, which should add those break values for you to change.
here is the difference between geoid and ellipsoid
it can be recoded by the Reclassify tool
Ok, i go to reclassify, but Roads cannot be in slope 330, max value is 100%, and I need to turn those 330 into 100%.
The terrain can be 330 (73 degrees) roads max 100% (45 degrees)
I thought the idea was to identify the areas where the slope was a maximum of 100%, and retain those slope values if they were less than that. If so, use the Con symbol, if not, then symbolize the data. You can reclass the values > 100% to be 100%, but that would be misleading.
