thank you Eric. it did work. appreciated jamal Jamal, We intentionally dissolve the pixel boundaries (for continuous pixel values) so the output is not so large. This is also why we do not allow you to convert float rasters to polygons. You could potentially end up with billions of polygon records depending on the size of your raster. I would suggest using the Create Fishnet tool that is part of core ArcGIS Desktop. It might take a long time to process if you are going to be creating a lot of cells. If you need to have the raster value associated with the fishnet polygons, convert your raster to points and do a spatial join. Regards, Eric

thank you ERIC. it did work. now, how to say that it is solved? appreciated Jamal Jamal, Your expression is using �??wt�?� but your layer name is �??wt1�?�. Eric

Thank you for the answer Eric. i'm trying to replace the nodata cells with the 3x3 average window but didn't work please, see the attached images what might be wrong? thank you regards Jamal Hi Jamal, I reviewed your screenshot and you are specifying FOCALMEAN which is not a command in map algebra at 10.0. Please review my earlier post wherein I provide the syntax to use at 10.0. i.e. FocalStatistics Regards, Eric

it didn't work!!!! help, please Thanks Dan. I checked with the Arc10 Resource Center (URL: http://help.arcgis.com/EN/ArcGISDesktop/10.0/Help/00q8/00q80000006m000000.htm) for help with the syntax and case but unfortunately it's still not working: Con(IsNull([point2ras]), FOCALMEAN ([point2ras] , RECTANGLE , 3 , 3, data), [point2ras]) When I run the expression with that structure, Spatial Analyst returns an error saying that the name of the input raster is not defined. I inserted "" around the layer name, re-ran it, and got a different error ['expected a raster or layer name']. I've attached a screen-capture of the error messages, for reference. Any other suggestions? Thanks, Matt

Is there a tool to convert the cells of a raster to vector? Please, see the attached raster Is there a way to get the cells on this raster to vector such that each cell becomes a square in the vector class, therefore, the vector will contains feature equal to number of cells in the raster Of course, I know the tool ???raster to polygon???, but his doesn???t give the vector with individual squares Thank you Regards Jamal

How to replace the cells that have ???no data??? with average values of the neighbor cells? Please, see the attached image that shows my question Many cells in the given raster have no data, all what we need is to fill the ???no data??? cells??? with the average values of their neighborhood We need to fill all the area bounded by magenta border. How could we do that? Thank you Regards Jamal

Yes...That does make sense Patrick, thank you. Hi Jamal, When you run the Clip tool, it does not automatically update your Attribute Table. There is an enhancement request to have the Attribute Table updated. If you run the Build Raster Attribute Table tool, you will get the updated information. Patrick

anotehr note! i switched the origional raster to be of type GRID instead of being TIF...! then it did work!!!! but does this make any sense? why the format of the raster is important? why does it affect the result??? please, have alook on the attached image Jamal you have to set the extents explicitly in your Environments to be the extent of the layer used to clip the input raster

thank you for the answer. sure, i did...please, see the attached images Jamal The clipped raster has the same cell numbers as the original one!!! Why? Please, see the attached image that shows the case (particularly the tables!!!) The clipped raster has the same cell numbers as the original one (exactly the same) despite the fact that the clipped one is just a part of the original raster!!! Of course�?� really weird!!!!! What might be the problem? Thank you Regards Jamal

What is the effect of multiplying two rasters that have differnt cell size? please, see the attached image that shows my question? also, if they have the same cell size, should they be identical in the two rasters to be multiplied? what if they are of the same size in the two rasters but not identical? thank you regards Jamal

Has anyone calculate the carbon content of the forest based on an image of band4 and band5? The method: Biomass Volume = - 478.58 + 4.5041 ?? ND45 (Mt/ha) ND45 = 128 ?? ((TM4* - TM5*) / (TM4 + TM5)) + 128 Carbon = Biomass Volume ?? 0.5 (Mt/ha) Critical point: ??? The vegetation index includes water. Then how to extract the forest from this index? Based in which values? For example, the values of the NDVI are indicative: Very low values of NDVI (0.1 and below) correspond to barren areas of rock, sand, or snow. Moderate values represent shrub and grassland (0.2 to 0.3), while high values indicate temperate and tropical rainforests (0.6 to 0.8). in this case we can extract exactly what we need. In which sense is this applicable for ND45? ??? Do we need to process the pixel values of ND45 according to the average over 11x11 pixel window? Does this affect the result and the approach? ??? As the result of this approach is a raster that contains the values of carbon at each cell in (kg/ha), then is it correct to calculate the weight of carbon at each cell by multiplying the value of that cell with its area and then to sum all of these values up? Should we convert the area of the cell to ha (hectare) first or this is included in the equation? ??? Is this approach applicable if we have an image from Landsat ETM+? any idea? Thank you Regards Jamal
