Google uses WGS84 as the underlying datum, and will not do any coordinate transformations. So, reproject your data to be geographic WGS84, and it should line up. Best Regards, Jim ... View more

What if you separated the floors into different polygon layers, with the highest floor on top. Then use feature weight to prevent labels from a lower floor from printing over the upper floor features. Best Regards, Jim ... View more

Sara, have you looked at the Density tools in spatial analyst? Perhaps a point density analysis would get you what you need? Best Regards, Jim ... View more

Zonal statistics as Table is the appropriate tool. Is your dataset extremly large? Does your polygon layer have many classes that you are evaluating? When does it crash, and what is the error message generated in the Geoprocessing Results window? You could try limiting the analysis to a single polygon class, and see if that works.

You need to be MUCH more specific regarding your analysis goals. This question is too broad in scope for an answer. Regards, Jim ... View more

The analysis can only work with the intersection of the extents, or the areas covered by both data sets. Otherwise, there are no constraints, and the values would go to infinity where there is no rock top to provide a stopping point. Regards, Jim ... View more

You should run the thin tool first. Spatial analyst tools >> Generalization >> thin This will limit the number of pixels used to represent a vector object, and thereby produce better output on the raster to vector conversion. Best Regards, Jim ... View more

I believe this can be accomplished with "CON" statements in the raster calculator. I would nest the statements, working from highest ranking to lowest. So, in pseudo code: Condition1 ( raster1 not null, use raster1, else(condition2( raster2 not null, use raster2, else(condition3( raster3 not null ...... If you need more explicit instruction, send a reply to the thread, and I or someone else can elaborate. Best Regards, Jim ... View more

Could you be more specific? 1) Is this stored as a tool in a toolbox? (I will assume Yes) 2) when you right click on the model in the toolbox, is the "Edit" menu item grayed out? 3) if it is not grayed out, what happens when you select "Edit". Does a window open or is the model blank? 4) if no window opens, is it specific to this model tool, or all models? 5) if it is only this model, is it open / locked by another instance of arcMap?

Happy to be able to help! If you could, please mark the thread as answered, so others with similar problems can find a solution through the forums more efficiently. Thanks, Jim ... View more

Meltem, you can send me a private message if you choose by clicking on my user name and selecting "Send Private Message". However, then you are completely dependent on me solving your question, and completely dependent on my availability to look into it. If you keep this in the forum, you have hundreds of more people available to assist. Regards, Jim ... View more

I have not experienced these issues. I would try using the "Repair Geometry" tool and see if that corrects issues for you (These appear to be generated in software other than ArcMap). Another tact is to export the layer to a new shapefile, and see if that helps you. Regards, Jim ... View more

In the same vein as the definition query, it might be a symbology thing making it invisible.  If your attribute is a different value than what your symbology draws and you have unchecked 'all other values' from showing up then it would be invisible. Not in this case, as it disappears from the attribute table as well. ... View more

It sounds as though you have a definition query on the dataset, and the feature you are creating is being excluded by the query, so it "disappears" from the table and display. Best Regards, Jim ... View more
