I"m learning Arcgis. I have a DEM that I did contours from in Analyst. It gave me the contours, set at 1. Where do I set that it means 1 FOOT intervals? Also, it's showing them in sea level altitude (179-200). I need them to say 1,2,3,..etc.
I added a field, LocalHt, and trying to do a field calc on it. [localht]=[contour]-179 but it doesn't work. all values show zero.
I tried Pyton script, but don't get the syntax right in it either.
My goal is to label contours at 1' intervals, and have them shown throughout the area (about 3 acres).
Solved! Go to Solution.
What software and version are you using?
If ArcMap, take a look at this article:
It indicates where you put in the contour interval (where you would specify 1 foot).
After that, you can properly label them.
I tried the Maplex engine. I have some elevations on one part of the area but not the area I need. I tried the repeat feature, but I don't know how far apart 'map points' are or if 'inches' or 'mm' refers to ground length, screen length, map length, or what. What is it using for reference length?
I click the contours button graphic, and I don't get the popup. I get a crosshair and can click on the map and create one single contour. I have to 'undo' to get it to go away, and there's no way to manipulate several of them (no entry in the list on the left) to change colors, interval, etc. Why no popup?
As far as the original question, I have found that the expression window placed the name of the column for me and I didn't have to include it in the expression.
I have also found the Maplex engine for labeling. I'll try that.
