Although Eric is right that answering these questions is difficult without looking at the data, I know vegetation cover for certain species or vegetation types tends to vary erratically and discontinuously. This violates the basic assumption of continuity of the interpolated variable that interpolation methods tend to have. Data like this may be better processed using a generic statistical package like SPSS etc. E.g. to estimate an average "moss cover" percentage beneath different types of forest, or on different soils, and see if there are statistically significant differences between classes. If you than know that forest type A on soil B tends to have a certain "moss cover" value C, you might use that to classify an existing map of forest or soil types to get some estimate of "moss cover" in unsampled regions. ...

Since Esri enabled ArcGIS Desktop to create a view (as of 10.1, I believe), I would have expected that view to behave as any other geodatabase table behaves i.e. - to be geodatabase aware.  But in this case, it's just a button which performs a non-geodatabase function. Exactly!... ... View more

BTW, I have now verified the viability of the solution I wrote in post #2. I exported a domain as described there, and than modified both an ArcGIS Query Layer's SQL statement to incorporate the domain's description, and I also tested modifying the underlying database view's SQL (Warning: don't do both at the same time!) to join the exported domain table using SQL Server Management Studio. Both worked like a charm... the description of the domain nicely replaces the code in both cases. ... View more

Marianne, As soon as you start defining true database views, as SQL statements stored at enterprise database level, you are actually leaving the ESRI and geodatabase "realm" of things. Although it is easy to say that ArcGIS "knows" about these domains in all other situations where geodatabases are accessed through one of the ArcGIS Desktop or Server applications, this is all with ArcGIS "knowing" it is using a geodatabase, not an ordinary database without ArcSDE Repository. Hence ArcGIS can extract the necessary information from the table with XML columns storing the domains (the GDB_ITEMS table of the ArcSDE / Geodatabase Repository). ArcObjects handles this. When you define a database view, versus doing something like creating a layer with Definition Query in ArcMap, even if it accomplished through ArcGIS for Desktop tools and menu options like the new ones added in the 10.x releases, it is stored and managed by the database. The database doesn't "know" about any of the specifics of the geodatabase model, like where the domain information is stored. It also can not "join" the XML column information about the domains automatically to your base tables. And since ArcGIS sees this same database view as any other ordinary view, it won't be able to extract this info either (unless ESRI deviced some elaborate code to still consult the ArcSDE Repository, even for ordinary database views not registered with the geodatabase). That is why the export with the Domain To Table tool is necessary. Of course, ESRI might potentially be able to offer an option to automatically convert domain codes to domain descriptions in a future release by doing an export automatically and modifying the SQL statements on the fly... but this is probably far less easy than it sounds. In the mean time, automating the creation of database views including exported domains using the Domain To Table tools, most likely through Python scripting or ModelBuilder, is probably your best bet. ...

You may need to adjust the �??Show:�?� setting in the top of your navigation menu from �??Web Content Only�?� to �??All Content�?� in order to see all the samples. Jeff Jeff, maybe it would also be good to mention that there two more things required to make this work: - You actually need to have an ArcGIS Online account (can be done by registering your personal ESRI Global Account, as I just did). - Select the "Show ArcGIS Desktop items" checkbox. Without this selected, nothing will be shown, even if you selected "All Content"... ... View more

We are looking for guidance regarding a geoEvent SQL Server database. One ESRI demonstration video said that if we have moderate to large volume, best practice is to have a separate server and that hundreds of events per second is �??moderate�?� volume.  Is there literature for best practices guidelines for setting up our servers with regard to transaction volume and types? Yes there is (well, at least for ArcGIS for Server's most used service types, I don't think it gives any specific guidelines for GeoEvent processor yet) : ESRI System Design Strategies webpages There are even Excel spreadsheet tools there for doing preliminary calculations (see this page about the Capacity Planning Tool), but it probably requires the accompanying book to effectively use them, as there is a ton of options in there. The benchmarks for certain hard- and software configurations listed on the System Design Strategies pages will be of help too though... ... View more

I am currently working with java script API and need to integrate  our client sales data with the esri map. They have bought arc gis server and i m currently playing with evaluation ARC GIS server. i create two database connections via Arc catalog for both data bases. no luck after that to my task. Query Layers (introduced at 10.0) are most likely the answer to your issue. They allow you to run and access (and publish via ArcGIS for Server in a Map Service) arbitrary SQL queries against any database, even if not geodatabase enabled (like a sales database). What is a query layer? (10.2 Help) Just mind the caveat mentioned in the link below, you may need to define database views in order to be able to publish a complex query. Publishing complex queries including joins etc. is not directly supported in ArcGIS for Server, but defining a proper database view circumvents this issue in an effective manner: 00075: Query layer has a complex query ...

The layer that has a problem is with more than 1000 records ... Meanwhile, I have another layer with about 240,000 records and had no problem when synchronized. The potential 1000 record issue as mentioned in the bug report Asrujit pointed out, is not about the total number of records a Feature Class has, but about how many records you need to synchronize between the two replicas. E.g. if you deleted over 1000 records in the parent, and these now also needed to be removed from the child / relative replica, than you may run into this issue. So the question is, did you delete over 1000 records from the layer having a problem synchronizing? ... View more

Still, this is weird that the 'Query Related' doesn't work in one way (QueryLayer Table to FeatureClass) but then it works either way, once I test it from the FeatureClass Layer to the QueryLayerTable, how could I test this in ArcMap ? I do know the "%" character is used for in-line variable substitution in ArcGIS ModelBuilder and Python, but how that would relate to the sign showing up in the Properties dialog of the layer, other than some minor bug, I couldn't tell. It sure doesn't show up as I test it here on some dataset. Another scenario might be that your database actually does contain % signs, either as the true fieldnames, or as the field's aliases, and that this dialog reveals either one (the true field name or the alias, more likely the alias), while you may not actually have been aware of it up to now... Still, this is weird that the 'Query Related' doesn't work in one way (QueryLayer Table to FeatureClass) but then it works either way, once I test it from the FeatureClass Layer to the QueryLayerTable, how could I test this in ArcMap ? I can't tell why it still isn't working. However, to test this in ArcGIS, you just need to add both the Feature Class to the ArcGIS TOC (Table Of Contents), and the table as a Query Table to your MXD document. Then right click the layer, and establish the Relate via "Join and Relates". Actually, you already did these steps. To test the functioning in ArcGIS, you could do the following: - 1) Right click the Feature Class, and choose Open Attribute Table - 2) Select a record for which you want to show related records in the other table - 3) In the button bar of the attribute table, click the most left button, opening the menu - 4) Choose Related Tables/YOUR RELATE NAME, this will open the related table showing the related records for the selected record you chose in step 2) Another option to test your Relate is to use the Identify button. Click on a feature in the Feature Class, than expand the "+" signs to see the related table and related records ... View more

then if it lives in arcserver ,, is it connected to any service of arc server ??? I mean am I stuck to the map services and other services published on the arc server or it can work and manage the resources on the sde ????? You should probably ask this particular question in another sub-forum, like: ArcGIS REST API ArcGIS Runtime SDK for Java ArcGIS Server (10.0 and prior) SOAP API as there will be far more expertise there for answering your questions. That said, just looking at the documentation in the Help, I get the feeling you should be able to make calls to such a SOE service without involving map services, just like calling any ordinary SOAP/REST based webservice. To do what you want, the ArcGIS for Server would of course need a (ArcSDE) Direct Connect connection to your enterprise geodatabase, so all prerequisites for that, like a proper database driver installed on the server where ArcGIS for Server resides, would need to be fulfilled. Also see this remark on the What is a server object extension? Help page: "Additionally, if you want to write custom property pages for your SOEs beyond those automatically generated, you must have a knowledge of Windows forms development or Java Swing (for ArcCatalog pages) or web forms development using Hypertext Markup Language (HTML) and JavaScript (for Manager pages)." ...

Esri's use of "deprecate" is consistent with the rest of the software industry.  They try to be as explicit as possible (hence the update to include the 10.2.2 service pack), but predicting the future is notoriously hard, especially 2-3 years out, when most deprecation notices are produced. I totally agree and fully appreciate ESRIs efforts to be as explicit as reasonably possible, considering the constraints imposed by customers, developer time needed to make changes, and any technological challenges encountered. I disagree with your assertion that it would be possible to deprecate something at the version in which it was removed. ... There is no hard-and-fast "n vs n+1" rule in the deprecation market, yet it is the minimum effective notice that can be given Vince, I wasn't asserting anything, just explaining that many people, even those in the software industry, aren't actually much aware of what the word "deprecation" means, hence I was suggesting that some other type of wording might be more effective in communicating it, especially when more or less "final" decisions have been made. This is especially a challenge for non-native English speakers, like myself... Imagine if aircraft manufacturers deprecated landing gear in an announcement that caused the wheel axles to disintegrate. :D:rolleyes: ... View more

my question is : can I use the arcobjects "server object extensions" to apply these functions ?? or do you recommend me to use something else ??? If it needs to be a web based solution, than yes, although I have never used it, from what I read about Server Object Extensions, you should be able to make use of that for accessing both ArcObjects based functionality, and geoprocessing functionality related to geodatabase management. Don't forget though the possibility for arcpy geoprocessing services on ArcGIS Server as well, as also highlighted by this Help topic (although more related to webmapping and editing, and not so much to the geodatabase management tasks you seek): Alternatives to server object extensions ...

Actually, the ArcSDE API and command-line tools were deprecated with the release of 10.2 (and will not be available at the next major release of ArcGIS). - V The use of the word "deprecate" keeps causing confusion, especially for non-native English speakers, and maybe ESRI should replace it with more clear statements, especially there where final decisions about the fate of some component have been made. The meaning of it in for example the The Free Dictionary is also ambiguous: "3. Computer Science To mark (a component of a software standard) as obsolete to warn against its use in the future so that it may be phased out." Nowhere in this definition does it say that deprecate at release "n" means no availability at "n+1" (which seems the definition used by ESRI), instead of no availability at "n". I also can't even find this definition of "deprecate" in the on-line version of the Oxford Dictionaries, even though an entry for "deprecate" exists. But maybe the ambiguity is what ESRI seeks??, allowing the possibility to extend availability of the software if demand by customers requires it? ... View more
