Topo to Raster error

francescarusso

Dear all,

I have received some isopachs contour line which I have tried to interpolate with the "Topo to raster" tool in Spatial Analyst. I had the same task a while ago and I didn't have any problem in doing so. Now I got all the time a message of error. I thought that it could be due to the data I have received so I tried again to do the Topo to raster with the previous data which I did interpolated a while ago successfully and now I get the message of error for them as well.

I do not really understand how is it possible. Does anyone has any suggestions?

Cheers,

F

Hi Neil,

this is a good question. The problem was that I have received an .mxd file within a geodatabase from a client. For some reason (and I put my question on this forum few days ago), once I tried to Repair the data into the .mxd file not all the layer were visible. of course I tried to make them visible but for some reason not all of them became visible anyway. So to see if the data were ok I have saved them into layer and opened in a new .mxd file and it worked. (I could see all the data perfectly).

The problem is that I believe that GIS sometimes decides to work and sometimes not  I have tried already many times to open them from the actual data (as you suggested)and it didn't work. Now I have tried again and it worked but just on the .mxd file that doesn't open all the data. If I try to do the same into the new mxd file where all the data are ok it doesn't work

BTW now I have the interpolation into the other .mxd and if I open it in the new one it doesn't look like the same. The one I have generated with SA is very smooth and when I import the raster in the other one is made of big pixel (please see pics below)

  

Any suggestion on what to do to make it smoother like in the first pic?

Thanks a lot for all your support
