Drawing 5K Contours

[MuhammadAzam]

Is it possible to draw 5k contours on the basis of 10k contours? If yes then how? also, what will be their accuracy?

[XanderBakker · Accepted solution]

If the source is contour lines digitized at 10K, with a precision of 0.5mm, this translates to 5m precision in the real world. Presenting it at a scale of 1:5000 will show the lines with 1mm error.

You can create a DEM from the 10K contour lines and generate contour lines from that DEM with an interval that you can use at 5K. Be aware that in that process you will be presenting data at a higher precision than the original source is. So this is not recommended.
