Contour Help

[JustinMarsh]

I am trying to make some sort of contour map to show how a disease spread throughout a country by years but anytime I click the contour button under spatial analyst nothing appears on the pop-up window. Am I going at this with the wrong approach? Does anyone have any suggestions on how I can make this type of map?

Thanks,
Justin

Assuming ArcGIS 10
1  Make sure that the Spatial analyst extension is toggled on
2  Open the Spatial Analyst toolbar
3  Select a grid in the dataframe
should be good to go if 1, 2 and 3 are done
