Hello Jeremy!

 

Hope everything is going well up there in Enid.  I found some 20 foot contour downloads by quadrangle on the USGS National Map viewer at https://viewer.nationalmap.gov/basic/.  It looks like you need more resolution than that, though.  Hope this helps.

I am trying to generate contours with 2 feet intervals for an area in Woods County.

I am using the Spatial Analyst Toolbar with a 1 meter DEM I downloaded from USGS as my input raster.

I clipped the raster data and converted from meters to feet.

 

I run this process;

 

 

The process creates my contours, however when I comapre it to a 10 meter statewide shapefile I downloaded from OKMaps, it does not look correct. The blue contours are from OKMap’s download. The contours I generated are shown in red;

 

 

Should I be using a different dataset for my Input raster?

Does anyone know what I am doing wrong?

By chance would anyone have contours for Woods County with 2 ft intervals?

 

Thank you
