I am a rice farmer in Arkansas and would like to create levees along contour lines in a field at a .2 foot interval. How could I utilize LiDAR data to map 0.2 foot contour intervals across my area of interest?

I got 2014 Lidar data from USGS Earth Explorer. 900 mb.

    Is LiDAR data available for your area of interest, or are you planning on acquiring new data? – Aaron Mar 1 '18 at 15:24

    Welcome to GIS SE. As a new user, please take the Tour. Unfortunately, we use a "Focused question / Best answer" model, which isn't well suited to Boolean or ternary questions (LiDAR could be used, to make a DEM, but that's only the start of the journey), or to "What software should I use?" questions (which could attract proponents of every package). What I would suggest is looking for a tutorial or blog post about doing something similar, then trying to reproduce it, and asking a specific question if you run across a problem. – Vince Mar 1 '18 at 15:27

    You've tagged this with arcgis-desktop - have you read the data into it? Does it have a contour generating option? – Spacedman Mar 1 '18 at 16:20

    When I was using 1m LIDAR in PA we could accurately get 2 ft contour lines, but your looking for .2' or 2.25" contours. That would be some very accurate LIDAR, and I'm doubting USGS would have a use for data that accurate. Their project areas are usually on a state and national level not the local parcel or field. While you could use their data to generate contours of 2" I would question the accuracy because of the data quality used. – Bill Chappell Mar 1 '18 at 19:07

    Please clarify. You have LiDAR of a flat field that you want to rice farm? You do not have a levee now but you want to use ArcGIS to create a new surface model from LiDAR that has the levees you want to build? – GBG Mar 1 '18 at 19:14
