I'm Joanne & I'm a newbie in ArcGIS... I Hope somebody can help me figure this out:
Specifically, I have a rainfall map (Isohyets) measured in mm (precipitation)... I wanted to know a particular value (precipitation) at any point between these lines...
How can I do this? Do I have to convert/interpolate these polylines so I could have a Rainfall raster instead? So that I would know the precipitation in any point based on cell values of the Rainfall raster? If so, how do I make a raster map out of my rainfall contours/isohyets? By the way, I have a DEM of 20-m resolution. Will this be of any help in converting/interpolating my rainfall map? Please help.
Thanks & best regards.
