I get bad results when using the Natural Neighbors tool. I think it may be a bug in 10.2. I found an old workspace from 4 years ago that will have been created in arc9.3. It contains a raster created using the Natural Neighbor tool - it looks good, nice and smooth - as shown below. However if I re-run the analysis, now in 10.2, from the Results tab using the same data I get all these rogue pixels - as shown below. I have struggled with this problem for a while and basically stopped using Natural Neighbors but I now think I have proof that it is a software fault and nothing to do with my data or settings. Does anyone else have this problem or any possible solution that will fix the Natural Neighbors tool? Although these errors are small, they do produce unwanted and unacceptable hillocks when the raster is converted into a surface. (images adjusted in photoshop to increase constast)

This all works fine for me - I'm on 2015 Advanced Concurrent. Maybe re-install will help?

Where in the world is your model? Try using the UTM zone - look up here..... NGA: (U) The Universal Grid System (UNCLASSIFIED) If the coord system is explicit in the data ArcMap will pick it up if you drop the data in there (indeed CE should too). If the data is in WGS84-LatLong I don't think it's supported by CE, you'll need to reproject into a system with metres as the base unit. I would've though the default 'raw metres' system in CE should give sensible lighting for most models.

Sounds like you have a solution so just a thought:- I wonder if the orietation of the faces is linked to the direction the polygons were originally drawn e.g. clockwise polygons face-up anti-clockwise polygons face-down...... or visa versa .......just a thought..........

Hi Jake, this is definitely useful - I've learnt somethin new. However, I ultimately need to output to tiffs so it looks like I will still need to mosaic the mosaic into a single tiff and then chop it up into tiles - do you agree?

Hello Geonet What's the best way to reproject multiple rasters i.e. tiff tiles that cover a county region. When I reproject tiles individually I get black edges on all the images from the rotational correction. So I'm considering merging all the images into a single tile before doing the reprojection - this is feasible in this case but for a larger area would not be possible; so what's the best route to take? Thanks, Ben

I'd recommend finding an area of GeoNet that is more taylored to these questions - I stick them in 'New to GIS' when I have this type of question. Completely agree that much of Esri's documentation, error/help messages are seemingly willfully difficult.

Indeed, InnerRect is a blunt tool. Threre's a process called CleanupShapes under the Shapes menu - not really familiar with what it does but otherwise I'd look at processing your footprints in ArcMap or some other programme in order to optimise your footprints.

You may have unnecessary points in your footprints - simplify them to just 4 vertices and I think you should get better results.

Is CityEngine 2015 real? I have found CE2015 system requirements but other than this thread I see virtually no other mention of it at all - no official announcement - no banner on the CE product page and still 2014_1 from the download page?

If your maps are images (rasters), when they're loaded in ArcMap you can choose to make a background colour transparent - i.e. make white transparent -- go to Layer Properties - Symbology - Check the Display Background Value(R,G,B) box and set the values to 255 255 255. This is unlikely to look very neat but will allow you to layer images and see through them - unless the images are compressed in which case this won't work very well. You could also try playing with the Transparancy control in the Display tab of the Layer Properties.

ugh,.... you're right, I had unique values in one of the columns in the test I set up. I like to challenge myself with clean spreadsheets and dirty formulas.

‎04-13-2015

I don't think you need to add columns you can concatenate it all in a single formula, and output either I or O depending on whether there is an error. Red text should point to your original sheet, replace the ... with the bottom row, and blue text should point to you new sheet. Ok? =IF(ISERROR(CONCATENATE(VLOOKUP(A1,A$1:A$...,1,FALSE),(VLOOKUP(B1,B$1:B$...,1,FALSE)),(VLOOKUP(C1,C$1:C$...,1,FALSE)),(VLOOKUP(D1,D$1:D$...,1,FALSE)))),"O","I")

Thanks - I'll look into gdal_translate.exe. The tags were apparently created by Arc's Clip tool.

Hi Luke - this sounds like what I need to do (you're right to assume they're tiffs, sorry for leaving off vital info). I need to ask some follow-up questions.....I'm new to gdal code and have not really used much code beyond arcpy. How do I run this code, is it python? How do I know if I have a working GDAL install? - I have lots of folders on my computer called GDAL in amoungst program files for FME, Arc and QGIS - the gdal website goes over my head somewhat. Thanks Ben
