Today access to RFT-templates stored with MD and published as ImageServices are available in Portal/Online - nice! ... View more

Thanks Cheryl, thats a path to follow ... something like "change projection" would be much nicer 🙂 ... View more

Thanks - lets see what comes first - another new Laptop to use (business cycle) or a solution 🙂 Regards Guenter ... View more

If you want to make it public anyway, why not give it to Esri to include in the global elevation service. Or tile it up and make it a cache to upload to ArcGIS Online via your account … And for the MrSID – do you have a license from Lizardtech to convert that size? You’ll need!

Is there a special reason you want to use MrSID? What is the purpose of this data after conversion? Where are you going to use it? A (tiled) TIFF with LZW or LERC compression or something “modern” like MRF would be great to store elevation data! In short: “complex” compressions algorithms like e.g. wavelength, namely like MrSID or ECW or even JP2, are compact for storage, but computational intensive to extract/use. They use up a lot of memory (for short periods of time) – which is usually no problem if e.g. used on a mobile device that has limitations on available disk storage – but it is “risky” when using on a server (blocking up your memory and cpu) and has no big advantage besides the disk space issue – which shouldn’t be an issue in most cases today. For transport across the network of the “resulting image” the transport compression is much more important – and this is not depending on the disk file format but on the server used. Thi si not to mention costs associated with some formats because for compression or server use there might be licenses needed from the patent holders. In short - proper use of GDAL open formats and storage options - like tiled TIFF with a proper compression – is very very good, still compact and a save and interoperable way to go. And as a direct reply to your question: If I recall correctly, only creation of MrSID files up to 50MB is free of charge, beyond that you need a lizardtech license … maybe someone who is more recent in information can help here … Von: AMOL DESHMUKH Gesendet: Wednesday, August 9, 2017 8:25 AM An: Dörffel Günter <[email protected]> Betreff: Re: - Re: Is there a tool to convert from TIFF to MrSID?

Hi, in short: The *.aux.xml File is ArcGIS specific. ArcGIS stores information there – e.g. after calculating statistics – so this information is available later. If you go to another system, they might be of no use … The *.xml Files are – as you detected – standard XML Files and widely adopted by many systems to store and read metadata that might or might not be in the header of the files, too If you got TIFF-Files (and TIFF knows a lot of header-information itself), you might be fine just using them, … you can easily use GDAL to read/list what the header in the file says. See previous posts.

I know you'll be loosing the live-link and update capability. But converting it to a graphic (right-click - convert to graphic) will at least give you a solution for now ... View more

There you go! 🙂  Thanks for commenting again. Have fun!  Guenter ... View more

Hi Nahide, from a quick scan that sounds like Python 🙂 If I got it right you know the NAME of the element you want to fill, or can create one - then you should be able to use the TextElement Class. Dont think you can just use dynamic text. Sure - you have to get the string part. If the document name has a structure as you say, something like this should do: import arcpy,os mxd = arcpy.mapping.MapDocument("CURRENT") #do this in two lines - safe bet if Path can contain additional underscores theName= str(mxd.filePath.split(os.sep)[-1:]) # now extract the number from the mxd-name theTitle = str(theName.split("_")[-2]) #I assume a logic of _Number_ here # and given you have an element called map title ... elm = arcpy.mapping.ListLayoutElements(mxd, "TEXT_ELEMENT", "MapTitle")[0] # set the text elm.text = TheTitle arcpy.RefreshActiveView() ...

You might run into what I ran into 🙂 The help of the tool states as the first "pre-requisit": Classify LAS Ground  Only the last return of LAS points with class code values of 0, 1, or 2 will be considered for reclassification as ground. If your LAS files use different class code values to represent unclassified or ground measurements, consider using the Change LAS Class Codes tool to reassign them accordingly. The classification process will also ignore points that are assigned with either the overlap or noise classification flag. So in fact if your data is REALLY unclassified - ArcGIS will not classify it. You (still) need additional tools. ... View more

Glad I could help. Never doubt ArcGIS can do it 🙂 ... View more
