Sorry that is what I meant, it will not allow me to use 'select by attribute' or 'eliminate' on many of the layers in my model. It will not allow me to connect them as 'Input tables' but it will allow me to use them to specify 'cell size' or 'mask' which is stupid as these layers are polygons not rasters. I can go into the tool and tell it to use any layer in the table of contents, BUT it doesn't connect to where it already exists in modelbuilder, it creates a new icon for it and starts a separate model in modelbuilder which is definitely something I don't want it to do. No one has had this problem before?

I am working on a large model with over 100 processes. I am nearing the end and ModelBuilder will no longer allow me to connect one polygon layer to Eliminate or Select by Attribute as an input table. Just gives the options of environment or elimination table. Anyone know why this is happening? To be more specific, I have MERGEd several polygon layers into one polygon layer. I now want to eliminate all polygons under a hectare in area. I place the SELECT and the ELIMINATE tools on my modelbuilder window and I cannot connect my polygon layer as an input table to either table. Please help.

Thanks Curtis, I was really afraid someone would respond with, "The tool works, you're doing it wrong." I admittedly know almost nothing about programming, but as someone with a firm understanding of common sense it seems it should be possible to have a statement like: IF pixel falls between contour ValueA and contour ValueB, pixel value MUST A<pv>B or IF pixel falls between contour ValueB and contour ValueB, pixel value MUST A<pv>C Any other option leads to the GIS outputting data that crosses invisible contour lines. Alternatively, something like: Contours have values: a, b, c, d Run interpolation FIND all cells with values: a, b, c, d Spatially compare to contour lines Do you find cells with values: a, b, c, d not closely associated with input contour lines? If NO proceed, If YES output error message: We are sorry this tool does not work. I feel I am better off just assigning the nearest value to each pixel and I am creating a model with over 50 processes so that someone else can run it. I hate to tell them, "Run this interpolation, then look at it and add common sense values manually until it looks less ridiculous." I probably sound pissed, but I mostly mean this as humourous with a hope someone at ESRI goes, "Hey that might work never thought of that!"

I am trying to run Topo to Raster on contour lines representing water runoff. First off I had to greatly reduce resolution just to get it to run and once it does the results are garbage. Reclassifying the result so that the colors break at the contour values shows that it does in fact take the correct value at those contour lines, but between them is some garbage. Between the 100 and 200 contours it has values below 0!! Shouldn't it be smart enough to know that is not possible without crossing the 100 and 0 contour? I have a pretty sound understanding of interpolation but it seems Topo to Raster for Arc10.0 does not. At several contours, value move in the wrong direction on both sides of the line! Looking at the 100 contour I have values greater than 100 on the side closer to the 0 contour, while on the side closer to the 200 contour I have values lower than 100. Of course the values then magically cross the invisible 100 contour again before actually getting to the next contour line. If this tool is so broken is there another means to turn contours into a raster? Looking at it closely the results seem worst at areas where a contour of one value neighbors itself which is bound to happen on all ridges and valleys in the data. Anyone know why it is doing this and how to make it stop? Is there an option to prevent Arc from apparently assuming the contour dataset is incomplete and it can feel free to add new ones? If a pixel falls between 100 and 200 contour lines it should be really easy to not allow it to have a value of -77! [ATTACH=CONFIG]12684[/ATTACH]

That would be nice, considering this thread was started almost 3 years ago and I signed on here to complain about the same things they were complaining about back then.

Agreed, trying to do basically the same thing.

Does bumping work here? Guess I'll find out.

I am having the same problem and my GIS proffessor tells me that the answer is that ESRI has not programmed this very common sense ability into its software and although it seems like this should be elementary we are out of luck within the ArcGIS framework. I hope he is mistaken, but I have been unable to prove it, it seems you are able to create relationship classes with ArcGIS, but not really use them the way even the most basic DBMS would allow.

I am looking for help with a problem I am having. I have a large spatial feature class linked to a non-spatial table using ArcGIS 9.3. I would like to be able to create a report that incorporates the data from the non-spatial table, but cannot find a way to do this on my own. It seems this should be an easy problem, but I have been unable to solve it. In specific I have polygons representing habitat types, and tables representing species and the habitat types they are found in. I want to be able to select a habitat polygon and have it output a report telling me what species are found there. Thanks
