I have a GeoEvent service polling ArcGIS Server for line features. The inputs are filtered by testing for the intersection against a line geofence. The filtering logic works correctly and only intersecting geoevents are passed to the intersector processor. I'm hoping the intersector will generate a point geometry representing the point of intersection between the line geoevent and the line geofence. Despite the filter positively identifying an intersection between the geoevent and geofence, the intersector issues a warning in the logs indicating the intersection between the two geomteries is null. Any suggestions on how to configure the intersector to generate a point geometry between two lines would be greatly appreciated.

Hi Ravi, We had a support ticket open with ESRI Canada, but couldn't reproduce the issue. We believe the issue is likely related to the servers configuration. Testing on two identical physical servers the issue is easily reproducible. We also setup a third server in a virtual environment and cannot reproduce the issues. We are currently trying to track down the issue on the physical boxes. We enabled Failed Request Tracing in IIS with a 20 sec connection timeout. The tracing again indicates that the process is getting hung-up on the ResolveRequestCache. Other than rebuilding the physical machines we are running out of things to try.

We are trying to track down performance issues with a GP services being accessed through the REST environment on Server 2008, IIS 7.5, ArcGIS Server 10 SP 3. In our testing the using Fiddler and Chrome Developer Tools we have determined the request is received quickly through the network, but the server is slow to send the response back to the client. In watching the performance monitor we can see the CPU usage spike when the Python processing is being executed, and messages returned from the Geoprocessing service indicate the geoprocessing is happening at a consistent rate. When the performance is high the response is received within 3-4 seconds, when it's slow it can take upwards of 1-2 minutes for the same request. Performance can change over subsequent runs 1-2 seconds followed by a 1-2 minute run. When are running a json recordset as input to the gp service, and receiving a featureset back. All testing is currently being done within the web interface automatically created server http://<task-url>/execute. Using Appcmd on the server it has been noticed that the application is hanging in the ResolveRequestCache state. Any help or suggestions on resolving this issue would be greatly appreciated.

I've been having performance issues between my develoment and production environments. The problem exists with a Geoprocessing Task using a Python script, a similar tool using only a model doesn't exhibit the same behavior. The development environment is running ArcGIS Server 10 sp 1, and will execute a the geoprocessing task without hesitation or delay. The same geoprocessing script when published on the production machine running ArcGIS Server 10 SP 3, has significant performance degradation. In looking at the server logs it appears the geoprocessing task completes the request in roughly the same amount of time as the development environment. The majority of the delay appears to be after the request has been completed and waiting for the server context to be released. Any suggestion would be greatly appreciated.

Here is a little context to the issue. We are mapping occurrences with information coming from two systems the first our Records Management System (RMS), and second the Computer Aided Dispatch System (CAD). The RMS system is updated by our personnel to reflect the address where the occurrence took place, after being dispatch to the location. The CAD system has its information pushed into the RMS system where a coordinate value is updated based on the dispatch location for an occurrence. In our situation the address having been updated by our personnel, is more accurate than the coordinate, especially considering the occurrence location is not always the same as the dispatch location. For example if a neighbor a couple doors down calls in to report an occurrence, and we used the coordinate coming over from the CAD system the occurrence will be mapped at the neighbors location who placed the call. We want to only use the dispatched location as a secondary option to help fill in the gaps where addresses cannot be geocoded using the address information. With the improvements to the locators in ArcGIS 10 we have a great opportunity handle this geocode workflow completely within a composite locator, and reduce the processing done using Python and the Geoprocessor. It may also open up additional possibilities such as a setting up a dynamic feature class, and reviewing and rematching our results. This currently is not possible because each geocoding set is processed independently using address locators and xy event layers, with all outputs append together in the end.

Investigating this further I've managed to get a very small percentage (1%) of points to geocode using lat/long values while batch geocoding a table. However, in these instances the geocoder appears to have problems interpreting the lat/long values as they are usually a couple of degrees from their true location. It also appears to have tried to reverse geocode the lat/long values and bring back a Match Address Value with a house number and address information. The address locator style is US Address - Dual Range, but I have also tried using lat/long with the US Address - Single Address, Single Field, and Gazetter. All reference data has been reprojected to WGS84 to try and avoid translation issues. The help documentation seems to indicate that if a table is geocoded using lat/long there is a possibility to have the values mapped to an Addr_Type of coordinates. However, I'm not seeing this behaviour - How can I get these results? http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//002500000025000000.htm

I'm trying to geocode a table of addresses using their lat/long values in a ArcGIS 10 locator style. The lat/long values return candidates when using the "Find" and "Geocoding Toolbar", but fail when batch geocoding a table, and in the review/rematch dialog. The goal here is to use a composite locator to first try geocoding to the street address, and fall out to the coordinate if the street address cannot be used. This process is currently done in ArcGIS 9.3 using the Python and a combination of geocoding and XY event themes, but with the enhancements in 10 we are hoping to consolidate this workflow into a composite locator. Is batch geocoding a table of lat/longs currently supported, or is the general rule to still use an XY Event Theme?
