I am able to import csv file, make shape file, interpolate then make contour from raster.. However, the problem I'm facing now is that, whenever I do a contour, the program will assume or calculate outside of the actual data points and this gives odd lines outside of the actual data points. How can i clean those out and make my map look nice and neat? </P><P style="min-height: 8pt; padding: 0px;">&nbsp;</P><P>Thank you</P></BODY></HTML> Thu, 28 Aug 2014 22:13:10 GMT DillomiUcharm 2014-08-28T22:13:10Z Contour map https://community.esri.com/t5/new-to-gis-questions/contour-map/m-p/19862#M18 <HTML><HEAD></HEAD><BODY><P>Hello,</P><P style="min-height: 8pt; padding: 0px;">&nbsp;</P><P>I am new in ArcGIS and for now I am working with bathymetry data.
