Jamal, The .gdb file (file geodatabase) cannot be directly converted to a .mdf file (SQL Server database file).  Instead, create a new geodatabase on the database server, then import or copy and paste the data from the file geodatabase to the geodatabase on the database server. Regards, -Kim Thank you for the answer Kim. Is this practical? i don't understand why we cann't add (connect) our file geodatabase to the server directly without the need to have MDF file or even to import the data into a new geodatebase? regards Jamal ...

Hi Jamal, Sorry I haven't had a chance to get back to you sooner.  I believe what you're experiencing is a data/version specific bug in the software.  I would not expect any user to type the min/max (unless it's a workaround) to reclassify some data.  I was only attempting, with that suggestion, to get you a reclassified raster that you could continue working with.  In an earlier post, I mentioned that I created a NDVI raster (from a single Landsat scene) using the Raster Calculator and was able to reclassify it without having to type the min/max or make any changes to the precision dialog.  I actually had to intentionally mess it up to get the same warning as you.  By default it was working as you would expect it to.  The main difference between you and me though, is I was using 10.1 Beta version, and we have different (yet similar) data. If you have the tutorial data installed you could use the same Landsat scene I used, to create your own NDVI raster and attempt to reclassify it to see if you get the error in 10.0.  See attached for data location.  If you can't repro the warning messages with the tutorial data, then it's probably specific to the raster values in your real dataset, and you might consider sending it to your local Esri distributor so they can forward it to us as part of a bug report. Best Regards, Eric Thank you Eric for the comprehensive answer. The issue here is the reclassification not the NDVI! I expected that the ArcGIS can reclassify any raster AUTOMATICALLY!!! by the way, i got the NDVI (fro the image) from ERDAS 2011 then added this NDVI to ArcGIS for further analysis! what about ArcGIS 10.1? when will it be available? and how come the ArcGIS 10.0 is full of bugs that much even with the very basic issues? very much appreciated regards Jamal ...

Jamal, Try increasing the significant digits to 9.  If that doesn't work, check the option to use "Format" precision.  For your min use -1.0 and for the max use 1.0.  This worked for me.  Optionally you could use the real min/max obtained from the layer properties > source tab > statistics section.  Those are the real min/max values.  The stats in the classification dialog are estimates. Note, your screenshot is the default.  Everytime you open the tool it should have those values.  Any changes will only 'stick' if you make the changes, run the tool, then run the tool again from the Results window. Regards, Eric thank you Eric. sure, if i change MANUALLY the min and max, then it should work!!!! my point is why ArcGIS is not able to get the true min and max automatically????!!!!! given that ArcGIS knows the actual min and max with right digital numbers!!!!!! why we are involved in such problem as user? my question is still valid: how to classify AUTOMATICALLY this raster? all the best Jamal ...

Jamal, In the Reclassify tool, click the button called "Precision" and send a screenshot of your settings.  As the warning is indicating (not an error message) you may need to make adjustments to the precision, or maybe you just need to get it back to the defaults if you already made adjustments.  I calculated an NDVI raster and reclassified it without any warnings.  Only after fiddling with the settings and reducing the significant digits to only a couple was I able to repro the warning messages your are getting. Regards, Eric thank you for the help erictrice. Attached is the screen shot for the precision. the problem that the reclassification of "image1_ndvi.img"  (attached in the previous post) generates this warning!!!!! what's wrong with it? what is the default? regards Jamal ...

Hi Jamal, Please convert your img file to tiff or grid format using Copy Raster tool. http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//001700000094000000 and then reclassify the raster again. Thanks. Thank you for the answer Tarun_Jaiswal. i tried it but didn't work. please, see the attached image why this error happens? regards Jamal ... View more

Great idea! If ESRI manage to meet all the ideas, then i think ArcGIS will be perfect. Slow process in enhancement: too little too late! what do u think? ... View more

Unfortunately, ESRI is very slow to respond in a very basic features and functions! ArcGIS 10 and ArcGIS 9.3 are different in tools arrangement!!!!!!! but not in adding development and addind crucail tools ... View more

The issue with Combine is that it is an integer value operation. Floating point (or text) raster table values wouldn't lend themselves to the desired combinatorial operation.  So --  you would like all the fields in the output table? In command-line ArcInfo GRID there is a command MERGEVAT (it exists in 9.x MOMA, but that's a secret) that does this. It basically did a Join Field between two raster tables, dropping VALUE and COUNT from the second input. That would be a nice little tool. I just may write a Python script tool to do that.... Send it to ESRI as an enhancement request! Thank you for the answer Curtis. Actually, I'm constructing a model using the model builder (attached) in which i needed to have a tool like "combine"! in this case, it is not useful to go back to ArcInfo workstation the "Combine" tool is very crucial but: - it doesn't keep the values of the combined raster as they are - it changes the names of the fields and replace them by the name of rasters!!!!!!!!!!!!!!!!!!!! very confusing!!!!!!! I'm not sure how can i proceed with my model!!!!! i need to connect all the part of the model but i couldn't due to the unavailability of some important tools in ArcGIS !!!!!! any idea how can i proceed? regards Jamal ...
