Hi Stef, I talked to an ESRI analyst at the UC. Though she didn't have a quick and hard solution for us, she did offer some good advice! Once you have created all your link points, before hitting Update Georeferencing, save the link table. That way, if it doesn't work, at least you can re-load the links when you go back to try it again. She also said that what is causing it is probably some errant pair of points (or link). She said to really pay attention to what is on the link table. If there's a row that's amiss or has an usually high RMS, delete it, then try to update. If all else fails, just rectify. ... View more

I just started having this problem. I've been using ArcMap since...since...well, since it was ArcView. Anyway, I've never had a problem with the georeferencing tool, but now I am getting this exact problem running 10.5. It just started doing it yesterday. Completely out of the blue. I haven't changed any setting (that I know of). And the option noted above by @Brandt Meyer IS unchecked. Any other ideas? ... View more

To Joabelb and Pattersonc, It appears that with the current version of ArcMap that I have, it is not possible to process the RPC file. I eventually had an image processing vender do it for me. ... View more

Dear all, I have a followup question to my earlier request. How do I activate spatial analyst? I have added the extension but I do not see the tools icon that would take me to spatial analyst regards minti Go to Customize (in the menu bar) then Extensions. Click the little box next to the extension you want to use then close the dialog box. You should be able to turn on the Spatial Analyst tool bar after that (right click on the menu bar, then scroll down the list of tool bars. Also, the idea is to calculate the rainfall at your farms, right? That's the question you want to answer? Once you interpolate the rainfall values over an extent that covers your farms, then you can extract the values from the interpolated surface to your farm points. (Look up Extract Point Values) ...

What do the points represent? Is there data associated with those points, like elevation or chemical concentration or some other numeric value? Or do they represent something like vegetation type? Now, why do you want the data in raster format? If the points have elevation data associated with them, is your aim to create a topographic surface? In that case, you'll probably want to use one of the Interpolation tools in the Spatial Analyst Tools in ArcToolBbox. I've always used the Topo to Raster (using contour lines, of course), but I'm sure you can get similar results with the IDW or Kriging tools to interpolate those values across a surface. Did that help? ... View more

I believe ArcMap reserves certain field names for its use. You could rename your field to something that is not on their reserved list? ... View more

I guess another thing to check is if the projection is correct (or the same) for both raster sets you are creating the new raster from? ... View more
