Bula everyone,

I have a set of raster contours and spot heights and have created a DEM from MapInfo which i than exported to ERDAS. However, my output DEM has holes, i know these are zero value areas but do not know how to edit to get them all filled out.

Also, i have tried using spatial analyst in ARC using interpolation, topo to raster but i keep getting an error message that says Too many points in a contour polyline''

can someone please point me in the right direction from here.

Thanks
Litia
