First thanks for your Help I have been trying to find an answer on previous question but I could´t. I am trying to convert a shape file into a raster, but the ARCGIS gives values only to outside cells, not inside´s, so I get a raster with a hole in the inside with the shape of the feature, How can I inverse the results?

Thanks again

If you convert a polyline shapefile to a raster it will generate non-nodata cells only at the locations of the lines. Same goes for point shapefiles. If you want a raster covering the whole enclosed area, you need to have a polygon shapefile and convert that to a raster. –  Martin Mar 19 '13 at 9:13

I hope you can see it ![This is the image of the raster I obtained][2] [2]: i.stack.imgur.com/Xe6Si.jpg So if I undertood correctly I have to transform the polyline into polygon –  Pablo Mar 19 '13 at 9:38

If you convert a polyline shapefile to a raster it will generate non-nodata cells only at the locations that overlap the lines. Same goes for point shapefiles. If you want a raster covering the whole enclosed area, you need to have a polygon shapefile and convert that to a raster, meaning that you have to convert a polyline feature to polygon if that is what you have.
