Are you sure the script is running at all when called from the command line by your other program?  If you try printing 'hello world' from the script, does that even work from the command line? ... View more

Agreed.  The words keep coming out of their mouths, but actual progress has been painfully slow.  Now they have released 10.3 and formally retired SDE command line tools, all while still missing quite a bit of functionality that used to exist.  It is not uncommon to find SDE-related bugs, especially relating to views, where Esri's Support documentation says to use SDE command line tools as the workaround.  I think the Development teams are putting the screws to their own Support staff as much as they are customers with this one. ...

Kirsten Pinkston‌, thanks for the additional information.  Yes, seeing more full releases in MyEsri does assuage some of my concerns.  I remain quite interested to see how well partial updates work. ... View more

I understand, both the situation and frustration.  For reasons only a shrink could speculate about, it bothers me more than it should when I have to stick with a workaround because something that seems so simple simply isn't.  Although addressing this issue has gotten easier with Python 3.x, it still seems more complicated than it needs to be. ...

Using a list of key-value pairs is definitely the way to go.  Sorting a list of keys works in this example, but in general, it doesn't ensure the original ordering is maintained like using a list of key-value pairs. ... View more

Dan Patterson wrote: Sorted dictionaries should be the norm for namespace, but alas, that won't happen.. Sorted or ordered?  If you meant ordered, there is some light around the corner with ArcGIS Pro since it uses Python 3.x.  With Python 3.x, one can create a metaclass and use the __prepare__() method to replace the normal/default/unordered namespace dictionary with an ordered dictionary.  I can't recall at the moment whether I have seen someone implement similar functionality in Python 2.x, but it surely wouldn't be as straightforward as in Python 3.x. ...

How are you setting the workspace environment?  Can you post the functional part of the code that isn't working? Do you have more than 1 Python install on the machine? ... View more

When it comes to discrete raster data, especially color maps, I have always thought ArcMap's rendering engine falls short.  Looking at how a section of 470012130.tif renders on my screen between Windows Photo Viewer and ArcMap. Windows Photo Viewer: ArcMap: Granted, Windows Photo Viewer is treating the image as RGB while ArcMap is dealing with the color map, but it just seems the quality difference shouldn't be this pronounced. ...

Switching to bilinear could make things worse in this case because the data is discrete, even densely discrete.  Bilinear resampling is more for continuous data, and even the Improving the display of raster data help page is really geared toward continuous data and not discrete data. ... View more

The ZIP file you reference has 2 TIFs.  Both are georeferenced, although only one of them has the term "geo" in it.  Looking at the TIFF image metadata shows the following, and ArcMap shows the same information. 470012130_geo.tif:  Geographic, NAD83 470012130.tif:  Projected, NAD83 UTM zone 10N Which image are you having problems with?  And what is the projection of the data frame? Your "good" capture didn't come through as an attachment so I am not clear on what you are expecting to see. ... View more

Although this is an older thread/message, I stumbled onto this problem recently and noticed some odd behavior with the ArcPy Geometry Classes and spatial references. As Neil Ayres‌ points out, including a spatial reference is a good practice.  The documentation of ArcPy Geometry Classes is a bit weak or confusing on this specific issue because spatial_reference is listed as an optional argument with a default value of None.  According to the documentation, there is no reason your original code shouldn't work.  What is happening might be related to a similar issue that was discussed in detail years back by Dan Patterson‌ and David Wynne in the Errors in arcpy's Polygon class thread. I don't know what exactly is going on, but I would say there is a bug in the ArcPy Geometry Classes.  Looking at the same set of coordinates with four different spatial reference scenarios: coords = [(147.7359, -35.5386), (147.7374, -35.5397), (147.7304, -35.5409),           (147.7304, -35.5409), (147.7255, -35.5439), (147.7249, -35.5416)] SR_list = [['noneSR', None],            ['emptySR', arcpy.SpatialReference()],            ['webmercSR', arcpy.SpatialReference(3857)],            ['wgs84', arcpy.SpatialReference(4326)]] results = [['SR_Name', 'Type', 'PCSName', 'GCSName', 'XYResolution', 'pointCount']] for SR_name, SR in SR_list:     pn = arcpy.Polygon(         arcpy.Array([arcpy.Point(*coord) for coord in coords]),         SR     )     pnSR = pn.spatialReference     if pnSR is None:         results.append([SR_name, SR.type, SR.PCSName,                         SR.GCSName, SR.XYResolution, pn.pointCount])     else:         results.append([SR_name, pnSR.type, pnSR.PCSName,                         pnSR.GCSName, pnSR.XYResolution, pn.pointCount]) for result in results:     print '{:<12}{:<12}{:<36.34}{:<12.10}{:<12.10}{:<4}'.format(*result) Yields: SR_Name     Type        PCSName                             GCSName     XYResoluti  pointCount noneSR      Unknown                                                     0.0001      0   emptySR                                                                 0.0         6   webmercSR   Projected   WGS_1984_Web_Mercator_Auxiliary_Sp              0.0001      0   wgs84       Geographic                                      GCS_WGS_19  1e-09       6   To me, this behavior seems odd.  Using no spatial reference (None), which is the default, arcpy.Polygon does not generate an error, but it effectively doesn't generate a polygon either (from a practical perspective, I don't consider a polygon with zero points a polygon, especially when it should have six points).  Using an empty spatial reference, arcpy.Polygon generates a 6-pt polygon using a spatial reference that has no type, no names, and no XY resolution.  Interestingly enough, although a polygon is generated with six points and all the Polygon methods work, none of the geoprocessing tools (CopyFeatures_management, etc...) that I tried would work with it, likely due to its nonexisting spatial reference.  Using the Web Mercator projection, arcpy.Polygon fails to create the polygon in question even though the coordinates are valid within the Web Mercator projection.  And finally using a geographic coordinate system, arcpy.Polygon generates the polygon we have been after the whole time. From my perspective, the none/default and Web Mercator spatial references should generate a 6-pt polygon but don't while the empty spatial reference should generate an error instead of generating a 6-pt polygon. ...

From Database connections in ArcGIS Pro: Note: ArcGIS Pro connects to enterprise geodatabases and enterprise databases (contains no geodatabase repository tables) on supported platforms, however, the contents of an enterprise database cannot be added to the Map at this time. Please read more about the Make Query Layer geoprocessing tool as an alternative to working with data stored in a database. ... View more
