northeastern Ohio | I want to make a topo map of a farm so that I can plan out a systematic tile. I imported my yield data from my Insight to Farmworks View. Pulled up the elevation data and it created the map shown below. The field ranged about 70 feet from low to high points. I want to create a map with breaks every 3 feet instead of random (the fushia range is 37', yellow is 5', green is 3', purple is 10'). Is there any way to change the legend in Farmworks so that I can do this? Or is there a better (free/cheap) program that would be able to use my ILF file?
Another thought: A few years ago, NRCS gave me a website that had very accurate elevation data for Ohio. I was able to make a topo map from that for another farm. If I remember correctly it was a large file and not easy to find the farm I was looking for. But it made a nice map and probably way more accurate than my yield data file (no RTK used). Anyone know where to find this data and help me navigate it again?
