Hello - I would like to know if there is a format or specic standard for sending coordinates of a mobile arcgis geoevent processor It might be helpful to back up for a moment and remember that GeoEvent Services are designed with four basic components:  Input(s), Output(s), Filter(s), and Processor(s). Inputs are inbound connectors and Outputs are outbound connectors. Behind every connector is an adapter and a transport. A transport is responsible for receiving (or sending) event data in to (or out from) a GeoEvent Service. Out of the box, GeoEvent Processor has transports for system files, Esri feature services, as well as the HTTP, TCP, UDP, and WebSocket protocols. On the inbound side, an adapter is is responsible for adapting or interpreting the event data received. Out of the box, GeoEvent Processor has adapters which support comma separated text, generic JSON, Esri feature JSON, and GeoRSS. Additional adapters intended to highlight product extensibility are available on the Esri" rel="nofollow" target="_blank">http://links.esri.com/geoevent-gallery]Esri Gallery, Partner" rel="nofollow" target="_blank">http://links.esri.com/geoevent-partner-gallery]Partner Gallery, and Community" rel="nofollow" target="_blank">http://links.esri.com/geoevent-community-gallery]Community Gallery. Since you are developing the mobile application intended to provide the data stream, and have identified the UDP protocol as your preferred transport, I would recommend formatting the data as comma separated text and leveraging the 'Receive text from a UDP Socket' Input connector available out-of-the-box. I would encourage you to take some time to go through the Introduction" rel="nofollow" target="_blank">http://www.arcgis.com/home/item.html?id=265c334a47994dcc95e1bd57cf20e98e]Introduction to GeoEvent Processor tutorial to familiarize yourself with how GeoEvent Services are designed to receive and process GeoEvents created from event data received as comma separated text. Updates to this tutorial will be available shortly which will make the content more approachable - but you should find the currently available tutorial adequate for your needs.

Yes. If you want to use a GeoTagger to prepare an event for secondary enrichment then the GeoFences used for tagging events with the GeoFence name must not overlap. ... View more

Hello Morgan - It works great, UNTIL I have overlapping presets and when it gets to my Joining Processor to Field Enrich off of the existing preset (polygon layer) it isn't enriching the field with data... If I understand the issue you are describing, you are running into a known limitation of combining a Field Enricher with a GeoTagger. Think of GeoTagging as a special case of event enrichment which only allows an event to be enriched with the name of a GeoFence (and optionally the name of the Category to which the GeoFence belongs). I'll refer to this as the "primary enrichment". As long as none of your GeoFences overlap, you can use the name of the GeoFence from the "primary enrichment" as a key to join the enriched event to the polygon feature from which the GeoFence was derived and complete a "secondary enrichment". The GeoFence and polygon feature are separate objects in this model. The GeoFence object maintained by GeoEvent Processor does not include all of the attributes of the polygon feature. Hence your need to perform a table join in order to pull in the additional attributes from the polygon feature. If one or more GeoFences overlap and the event's geometry is inside the overlapping area, the primary enrichment performed by the GeoTagger enriches the event with some sort of list of names which destroys the key needed for the table join and secondary enrichment. Another way of destroying the key needed for the secondary enrichment is to include the Category to which the GeoFence belongs with the primary enrichment performed by the GeoTagger. The attribute field of the original polygon feature from which the GeoFence was derived contains only the name of the GeoFence, not the name and category, so the table join fails and the secondary enrichment cannot be completed. - RJ ...

On a Windows installation, the elements you create from within GeoEvent Processor Manger (e.g. Inputs, Outputs, GeoEvent Services, GeoEvent Definitions, GeoFences, registered Data Stores, etc.) are persisted beneath C:\ProgramData\Esri\GeoEventProcessor. The folders you find here are not removed when you uninstall the product. They are left behind deliberately so that you can leverage what you created when upgrading to a new product release. If you first stop the Windows service being used to run GeoEvent Processor and then delete the sub-folders beneath C:\ProgramData\Esri\GeoEventProcessor ... leaving the .\certs folder ... you will have removed the elements you previously created. The C:\ProgramData\Esri\GeoEventProcessor directory structure will be rebuilt when you restart GeoEvent Processors' Windows service. To more thoroughly reset your product installation you will need to remove the persisted cache and files used by the product during runtime. Beneath your ArcGIS for Server product installation directory (C:\Program Files\ArcGIS\Server is the default for Windows systems), locate the ...\GeoEventProcessor\data folder. If you first stop the Windows service being used to run GeoEvent Processor and then delete the data folder you will reset GeoEvent Processor to how you find it immediately following a new product installation. The ...\GeoEventProcessor\data folder will be rebuilt when you restart GeoEvent Processors' Windows service. Hope this information helps - RJ ... View more

Hello Elias - Let's try some simple checks first. On the GeoEvent Processor Manager's Monitor page, is the event count for the Watch a folder for new .csv files Input increasing? Keep in mind that if a GeoEvent Definition is not available to construct a GeoEvent from the data received - the comma separated text in this case - the event will be discarded. Your indication that this is happening is observing the event count for the Input is not increasing on the Monitor page. You might try allowing the Input to create an event definition and checking whether or not your Input is expecting the name of the event definition to be included as the 0th field of the event data. Also, keep in mind that the first two lines of the CSV file are reserved for a comma separated list of field name and a comma separated list of field data types - your actual event data needs to start with the 3rd line of the text file. With no filtering or processing in-between the Input and Output, the event count 'In' and 'Out' for the GeoEvent Service should match. The GeoEvent Service receives the events 'In' and sends them 'Out' to the Publish text to a tcp socket Output. In this case, there's nothing to debug with regard to the Output, as long as you were able to open the TCP Console application and see the message confirming that the app is listening for events on the designated port. Have you tried stopping and restarting the the Watch a folder for new .csv files Input? This will clear the Input's buffers forcing a re-read of the CSV file. Please keep in mind that a known limitation of this Input is that once it has read data from a particular file, it will not re-read that file - even if the file's contents are changed. Deleting and dragging a new copy of the file into the folder being watched has no effect. The Input is remembering the file name and will not re-read the file to re-ingest its event data. You must stop/restart the Input in order to re-read the file, or change the file's name. Hope this information helps - RJ ... View more

Hello Diallo - You are on the right track. Yes, you will need some sort of application running on the mobile device to broadcast the device's position over a communication channel / protocol (e.g. TCP, UDP, HTTP ...) which GeoEvent Processor can monitor to receive the data. Alternatively you could have an application running on the mobile device which posts JSON to a GeoEvent Processor Input connector's REST endpoint ... or establish a REST endpoint the GeoEvent Processor could poll to retrieve position information from the mobile device. These are three typical ways to get event data into GeoEvent Processor. You might want to take a look at the NMEA" rel="nofollow" target="_blank">http://www.arcgis.com/home/item.html?id=1717c2f7fe5b497491234ce3a352bdd2]NMEA Adapter tutorial we have available on our Product" rel="nofollow" target="_blank">http://www.arcgis.com/home/group.html?owner=GeoEventTeam&title=ArcGIS%20GeoEvent%20Processor]Product Gallery. While this tutorial is probably not applicable to your GPS enabled Motorola device, reading through the tutorial may provide some clarity for you with regard to how GeoEvent Processor is used to receive data feeds from mobile devices which are broadcasting information over TCP / UDP. You might also want to take a look at the forum thread [url=http://forums.arcgis.com/threads/95071-esri-receive-features-rest-in]esri-receive-features-rest-in[/url] which describes one of the alternatives I mention above - posting JSON to an Input's REST endpoint. If developing a web application using the Silverlight API doesn't provide you a ready solution, you might consider leveraging one of the native SDKs (Java, Android, iOS, WPF, ...) to develop a Runtime application which can broadcast the device's position information.

Hello Kerry - Unfortunately, rework to the Manager to support the IE8 browser could not be completed for the 10.2.2 stability release. The development team has incorporated changes supporting the older browser into our daily builds of the 10.3 product, but please be aware that while all of the Manger's pages are rendering for us with these changes, the controls and page layout is not optimal. The results so far are impacting the Manager's functionality. Do your users have an option to use Chrome or Firefox on their systems? Keep in mind that if the Server itself has restrictions on what can be installed, it might be possible to manage the Server from a client machine onto which a later browser release can be installed. Hope this information helps - RJ ... View more

Hello David - I'd like to make sure I understand your question or scenario. You would like the ability to configure a filter element with an expression similar to GEOMETRY OUTSIDE FlightZones/${ZoneID} rather than naming a specific GeoFence such as GEOMETRY OUTSIDE FlightZones/ZoneA. This isn't supported in the current release. The spatial expression for a filter element (or Incident Detector processor element) will not substitute a value (e.g. an attribute value) for a variable (e.g. the name of an event field) on-the-fly as the expression is evaluated by the filter / processor when an event is received. The spatial expression must include the GeoFence category and a GeoFence name. Regular expression patterns are accepted, so an expression such as GEOMETRY OUTSIDE FlightZones/.* is valid. What you can do, at the 10.2.1 release, is combine a GeoTagger with a Filter in order to generate an alert when an asset is tagged outside of its assigned zone. For example, if you configured a GeoTagger processor to enrich events with just the name of the GeoFence they are found INSIDE, you could then configure a filter which checked to see if the name of the asset's assigned zone did not match the name of the zone in which it was most recently tagged. Something like the attached illustration. (Notice that I did not include the name of the GeoFence Category in the GeoTagger's enrichment, so I can use variable-substitution to compare the value from the field ZoneID (where the flight is supposed to be) with the value in the GeoTag field TaggedInZone.

Hello Ayman - To which Input are you referring?  At the 10.2.1 product release 'Poll an ArcGIS Server for Features' allows you to choose either the 'FeatureServer' or 'MapServer' endpoint of a published service to poll for feature data. Other product capabilities such as synchronizing GeoFences also support the selection of 'FeatureServer' or 'MapServer' endpoints. Are you trying to use a 'MapServer' endpoint and it is not working? - RJ ... View more

Looks like the folks from SharpenYourGISSkills did not include the demonstration data in their map package. The ZIP file available from the [URL= http://sharpenyourgis.maps.arcgis.com/home/item.html?id=42bbc4283b2b408dbc71d4ecc97aa032]demonstration page[/URL] has been updated. If you download the updated ZIP you�??ll find a GEP.gdb in the �?�/02 GeoEvent Processor/Data folder. As you noted, if you allow Desktop to unpack the map package, the *.mxd and supporting data are usually found in folders named v10 and v101 beneath the �?�/ArcGIS/Packages/ folder (usually in your user�??s My Documents folder). When I open the GEP.mpk from the download in ArcMap, my TOC is full of broken feature layers. The layers appear to be looking for their data in a database named GEP in an instance of SqlExpress named localhost_sqlexpress. You could either repair the map document by pointing its data layers to the GEP.gdb found in the �?�/02 GeoEvent Processor/Data folder �?� or use a copy of the GEP.mpk I�??ve attached to this thread. The map package I�??ve attached includes the GEP.gdb inside the map package�??s v101 internal folder ... so it should open in ArcMap cleanly without any broken layers. The reason, by the way, that you need to copy the data to an enterprise geodatabase in your enterprise is that feature services cannot be published with the �??Feature Access�?? capability enabled if the datasets supporting the map document�??s feature layers are in a file geodatabase �?? which is how the data is packaged for distribution when sharing map packages. Using GEP to update the data through a published feature service requires that the 'Feature Access' capability be enabled. Hope this helps - RJ ... View more

Oops - Dennis got a response posted while I was writing mine. Thanks Dennis! Hello Debra  - Can you please confirm the version of GeoEvent Processor you are installing?  With the 10.2.1 product release the Service Designer was retired and the functionality for designing and publishing GeoEvent Services was incorporated into the GeoEvent Processor Manager. We are working on updating the "Intro to GeoEvent Processor" tutorial to reflect the changes to the product. We will be posting the updates to the product gallery as soon as possible. Thanks - RJ ...

Hello Ayman "? If the event count for your Input polling ArcGIS Server for Features is not indicating that any features are being received, this is usually because an existing event definition does not match the data being received so the Input"?s adapter is not able to create a GeoEvent. I opened your map document from the map package you posted. None of the feature coordinates contain null values, but I did notice that several hundred of the UNIT_DBID attribute values were null. I used ArcMap"?s field calculator to assign those value to -1, just so that all of the features and attributes would have valid non-null values. I published the map document to my local ArcGIS for Server as a map service with feature access enabled (so I have a feature service as well). In GeoEvent Processor I created a new Input "?Poll an ArcGIS Server for Features"? with the following configuration. [ATTACH=CONFIG]30956[/ATTACH] The Input fs-poll-in immediately received 804 new events "� and every 60 seconds another 804 events were polled from the feature service. The GeoEvent Definition generated for the events looks like: [ATTACH=CONFIG]30957[/ATTACH] Note that you do not need to incorporate the Input in a GeoEvent Service or send event data to an Output to verify that an Input is able to poll ArcGIS Server for features. I would recommend using GeoEvent Processor Manager to delete the Input, GeoEvent Service, and Output you have created. Also delete any generated GeoEvent Definitions you have created for this data. Make sure that a newly created Input is able to create a new GeoEvent Definition. Be aware that the JSON adapter - the component used by the Input to interpret the data being received -  will generate a GeoEvent Definition based on the content of the first event received. The adapter will omit any fields from the GeoEvent Definition whose value is null. This is the behavior at 10.2.1 "� we are looking at changing it at 10.2.2 so that the fields will be created even if the attribute value in the first event received is null so that the generated GeoEvent Definition matches the schema defined by the feature service being polled.

Hey Dennis - We've taken note of the limitation with regard to event data not making it into the intended feature class due to incompatibles with the feature class"?s properties. We"?ll see what we can do to have GEP generate some sort of warning or error message "� What you are experiencing, though, is consistent with the design of Outputs in general. The GeoEvent Service will send a GeoEvent to an Output, and if the Output is able to use its adapter and transport to successfully dispatch the event, then it"?s done its job. If the XMPP Server, Email daemon, Web Server, ArcGIS for Server (etc.) are unavailable it"?s like you posting a letter but the Post Office failing to deliver it. GEP has done what it can do, but it cannot guarantee that an Instant Message or Email (for example) was successfully delivered. There are steps you can take to help insure event data is prepared for receipt by a feature service. If you suspect it likely that a data provider will be sending integer values which exceed the 32-bit range of an esriFieldTypeInteger (which corresponds to a SQLServer signed int) "� since GEP supports 64-bit long integer values "� you could configure a filter to direct values which won"?t survive entry into the feature service to send the event data to a system text file. Pairing the filter with a field calculator, you could even enrich the event with your own error text so that, reading the text file, you would know which events didn"?t get created as features (and why). Similarly with strings whose length is too long for your feature layer"?s field "� you could use a regular expression such as ^.{0,32} in a Field Calculator (Regular Expression) to truncate strings to a fixed length (in this case 32 characters). This will become easier with the string functions being supported in the regular Field Calculator with the 10.2.2 product release. I think I"?ll work that example into the Intro Tutorial "� using a regular expression to trim a string"?s length. I kind of like that "� Hope this helps - RJ ... View more

Hello Vassilo - To manage the carriers, you will need to edit the com.esri.ges.transport.sms.cfg file found in the ...\GeoEventProcessor\etc folder in the product's installation folder. The Windows default is C:\Program Files\ArcGIS\Server. After editing the file and saving your edits you will need to restart GeoEvent Processor. The first line of the file specifies the carrier names: com.esri.ges.transport.sms.carrierNames = Verizon, T-mobile, Sprint, ... The second line of the file specifies the domain (or SMS Gateway) used by the specified carriers: com.esri.ges.transport.sms.carrierDomains = @vtext.com, @tmomail.net, @messaging.sprintpcs.com, ... You will need to find out if your carrier(s) offer public / free SMS gateway access, and if so, get their gateway domain (e.g - @vtext.com).  Doing a quick search online, we have found a list of SMS gateways on a Wikipedia page - https://en.wikipedia.org/wiki/List_of_SMS_gateways ... but we cannot tell you whether or not Wikipedia is up-to-date. - RJ ...
