When you do the reprojection, you have the option to choose the cell size under the "Environments" button at the bottom. Regarding the resampling, the appropriate selection depends on your data: "The NEAREST and MAJORITY options are used for categorical data, such as a land-use classification. The NEAREST option is the default since it is the quickest and also because it will not change the cell values. Do not use NEAREST or MAJORITY for continuous data, such as elevation surfaces. The BILINEAR option and the CUBIC option are most appropriate for continuous data. It is not recommended that BILINEAR or CUBIC be used with categorical data because the cell values may be altered." Best Regards, Jim

I tend to use the "Try Except" statement in python. It is a simple bit of error handling that allows an exception (error) to be stepped over if you choose, and the rest of the data to process. http://resources.arcgis.com/en/help/main/10.2/index.html#//002z0000000q000000 Best Regards, Jim

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

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

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

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. Best Regards, Jim

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

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

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

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

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? Regards, Jim

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

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

Ken, I have not done animations using arcGlobe, but have done it using 3D analyst. Exercise 5 in this tutorial addresses a fly through animation. http://help.arcgis.com/en/arcgisdesktop/10.0/pdf/3d-analyst-tutorial.pdf Best Regards, Jim
