i have some problem viewing an ascii file in a structured way in arcGIS.

i have used IDL ENVI too to solve this issue but all data is not displayed.

    What is the problem? How did you use ENVI to "solve the issue"? What do you mean by "all data is not displayed"? (this begs for a screen shot) Since ASCII is an exchange format, but not a display one, what format did you change to, and how? – Vince Aug 22 '14 at 11:50

To see this work create a test Esri ASCII Raster format file (C:\temp\test.asc) with the contents below:

ncols 4
nrows 3
xllcorner 0
yllcorner 0
cellsize 1
nodata_value -999
1 2 3 4
4 2 3 3
3 2 2 1 

To create a raster dataset from the ASCII raster file use the parameters below in the ASCII To Raster tool or just copy/paste it into the Python window and run it from there.


It will probably add to ArcMap automatically, or if not, just do that manually to display it.

If this test works and your ASCII file does not then check using a text editor that your ASCII file has all the parts described in the Esri ASCII Raster format.
