The input must be a layer.  See below thread for similar discussion: http://forums.arcgis.com/threads/5736-Join-a-Feature-Class-to-a-Table-with-Python "Layer To KML - This tool converts an in-memory or file-based feature or raster layer into a KML file containing a translation of ESRI geometries and symbology." You can either use a layer in the TOC or a layer saved as a layer file. ... View more

Layer to KML should work fine. What is the error you are getting? ... View more

You have to loop through the layers.... Unfortunately, you cannot mark your solution as "Answered" in the new forums... Yet. This is really too bad because a lot of the former "gurus" are not participating as much. ... View more

Don't think this can be done without somehow referencing or looping through the map layers. (Which is what you mentioned you do not want to do) What exactly is it you need to achieve?  Did you look at IFeatureClass, IQueryFilter, etc? ... View more

They can be exported directly to DXF or DWG from ArcGIS. ... View more

I could not agree more.... Try $4,000.  This is the price of a single seat extension in Canada Maplex included.  I think Maplex used to be $2,500 around version 8. I believe Maplex has started as a 3rd party product that was later acquired by ESRI which might have something to do with it being separate. (But don't quote me on it as i am not 100% certain about this) The most disappointing part is that even with maplex you will only gain full advantage of things like feature linked annotations with the higher, more expensive, licenses. (ArcInfo) Honestly, it's not even that good of a labeling engine.  Advanced labeling of contours and label masking is difficult even with Maplex. There are some alternatives i was looking into (also pricey but not as bad as Maplex) but i can't recall.... I posted a question to the good GIS folks on the stack exchange GIS forums, hopefully someone will have a recomendation; http://gis.stackexchange.com/questions/1875/are-there-any-good-alternatives-to-the-maplex-esri-labelling-engine ...

Thank You for your response.  I tried both approached with unsatisfactory results. I also received a response from GeoBase explaning that the anomaly has to do with rounding of elevation values.  They also provide some sugestions such as settings for Focal Statistics but it simply does not solve the problem.... Here is the response from Geobase: Thank you for contacting GeoBase for a follow up on improvements to avoid 'stair stepping' effects found in certain CDED data sets.  Presently there is no change attributed to the status of CDED specification requirements.  CDED data originates from multiple partners and data sources which make it difficult to manage a homogeneous product throughout. As you may now be aware the Z resolution in CDED files is causing the stair stepping effect.  According to CDED specification standards for this scale, all elevations readings are rounded to the nearest meter of elevation for the entire Canadian coverage with approximately an elevation point every 23 metres by 16-11metres for the 1:50K scale.   In flat areas, the rounding effect of the elevations causes homogeneous elevation plateaux instead of having a very gentle slope because the grid height values varies just a few centimetres.  It's these adjacent plateaux that cause the stair stepping effect.  In certain cases some smoothing effect may be achieved by using the Focal Statistics tool in ArcMap Spatial Analyst toolbox, neighbourhood tools before processing CDED files.  Depending on this software application you may be able to adjust viewing features with the tool menu for '' Neighbourhood=Circle, Radius=5, Units=Cell and Statistics Type=MEAN''.  But I don't think there is a perfect setting for all CDED files. There is a part of trial and error in the settings for each tile.  Because of this situation and the software you are using you may need to request assistance for your software provider to smooth out the look of you files. Because no perfect solution was arised from our tests, GeoBase did not provide a universal user guide for smoothing out CDED elevation data, in the Frequently Asked Question segment. ... View more

Thanks for your replies. The option to toggle between various stretches was available in previous versions. What might be new is the ability to define what type of stretch is being used by default when the raster is added to the map.  The above described rendering anomaly does not go away by adjusting the type of the stretch. Using None or Minimum-Maximum rather than St. Deviation just makes the hillshade darker and less pronounced. The anomaly is not as visible because it is obscured by the uniform shades but it is still there. ... View more

Looks like i am out of luck; see attached map search window from Geobase. It shows the same anomaly. ... View more

Thanks. At least I know am not the only one who has this problem. I keep coming across posts pointing people to GeoBase for higher resolution DEM but frankly it just isnt usable for hydrology, hillshade, etc. I believe the data is erroneous; i was in contact with some support people from GeoBase and i explained the problem in detail but they do not have the budget to fully investigate such requests. As for contours they suggested smoothing, but we all know that does not work for contours. It's almost better to use the source 3 arc-second srmt data then using the data at the existing state.  This data should be comparible to the US 1 arc-second srmt but it is not... For some areas Canvac/NTDB contours can be used with the Topo to Raster tool but for the most part the contour interval is too sparse to produce anything half realistic... Could you post an example of a smoothed/generalized GeoBasae 50K dem? ... View more
