Hi, I was wondering if it is possible to link a TimeSlider to your system time? I have a service that recreates a view of data with a 24hr lag and would like an application that would show an event happening at time 'x' when the application is loaded at time 'x' (obviously I can;t match on dates too, given the service is built on data a day behind real-time). Is this something that would need to be done using Tracking (or GeoEvent Processor in 10.2)? Thanks, Karl ... View more

Hi, I have a table of values associated with geographic positions. What I'm trying to do is use the result of an address search as the centre point of a few buffers (50 metres, 100 metres and 250 metres) and sum up the values of the geographic positions that fall within the respective buffers. I am scripting this in Flex. Any help here is greatly appreciated. (I'm using FlexAPI 3.2 & ArcGIS 10.1) Thanks, Karl ... View more

Hi, I'm trying to get rows in a table populated with values defined by an end-user. The user will have three boxes to enter two double fields and a yes/no or string field and then I want these values to be parsed to a table. I've been trying to create a solution in ModelBuilder (the end goal being a published geoprocessing tool I can consume via ArcGIS Server), with Value Variables but I've not been having much success. I have looked through various forum articles and ESRI help files, but would appreciate any further assistance (as many of the solutions I've seen have been for selecting values from pre-existing tables, which is not the case in my scenario). Thanks, Karl (I'm using ArcGIS 10.1 on a Windows 32-bit machine) ... View more

Hi, I'm wondering whether anyone can help me apply a data transformation on some co-ordinates? The input co-ordinate will be in BNG (WKID 27700) but I need to plot it on a service using tiled map services in Web-Mercator (WKID 102100). I use the following transformation in ArcGIS Desktop: OSGB_1936_To_WGS_1984_Petroleum - I understand that datum transformations are possible using the 10.1 Geometry service? I code my applications in Flex, so if anyone can offer some advice or guidance here, it would be appreciated. Thanks, Karl ... View more

Hi, I have a locator service which has access to a variety of fields and would like to write one of these fields into a tooltip that appears if the address is successfully located. The field is called ???Street_ID???. I am trying to adapt the example script found in the ESRI Flex Samples site - below is an extract of the mxml; if someone could highlight what I need to include to get this field to write, It would be appreciated: <fx:Script> <![CDATA[ import com.esri.ags.Graphic; import com.esri.ags.geometry.MapPoint; import com.esri.ags.layers.GraphicsLayer; import com.esri.ags.tasks.supportClasses.AddressCandidate; import com.esri.ags.tasks.supportClasses.AddressToLocationsParameters; import mx.controls.Alert; import mx.rpc.AsyncResponder; private function doFind():void { var parameters:AddressToLocationsParameters = new AddressToLocationsParameters(); parameters.address = { SingleLine: onelineaddress.text }; parameters.outFields = ["Loc_name"]; locator.addressToLocations(parameters, new AsyncResponder(onResult, onFault)); function onResult(candidates:Array, token:Object = null):void { if (candidates.length > 0) { var addressCandidate:AddressCandidate = candidates[0]; var myGraphic:Graphic = new Graphic(); myGraphic.geometry = addressCandidate.location; myGraphic.symbol = mySymbol; myGraphic.toolTip = addressCandidate.address.toString(); myGraphic.id = "graphic"; myGraphicsLayer.add(myGraphic); myMap.centerAt(myGraphic.geometry as MapPoint); if (addressCandidate.attributes.Loc_name.search("RoofTop") > 0) { myMap.scale = 9027.977411; } myInfo.htmlText = "<b>Found:</b><br/>" + addressCandidate.address.toString(); } else { myInfo.htmlText = "<b><font color='#FF0000'>No Location Found</b></font>"; Alert.show("Sorry, couldn't find a location for this address" + "\nAddress: " + onelineaddress.text); }; } function onFault(info:Object, token:Object = null):void { myInfo.htmlText = "<b>Failure</b>" + info.toString(); Alert.show("Failure: \n" + info.toString()); } } private function clearMap():void { myGraphicsLayer.clear(); Alert.show("Points cleared"); } ]]> </fx:Script> Thanks, Karl ...
