I didn't even know of the existence of the measurement tool 😕 I've implemented it, and it works fine, except for one thing: How can I use other measurement units than the standard choices. I'm particularly thinking of using nautical miles. Unfortuantely it doesnt look like the measurement tool supports nautical miles, although i am not sure why.  Maybe ESRI can comment on that. ...

I hear ya. What I'm trying to say is that there's a sweet spot:  can (should?) a parcel viewer also show zoning info? Yes, of course. Zoning is a logical addition and usually not more than an additional attribute. Now, does your parcel/zoning viewer app need 20+ additional map services, a TOC to manage them all along with multiple toolbars with map navigation tools that 99% of your users will ignore and probably not understand? I hope the answer is a resounding no. Other features like measuring and geocoding have a place (especially geocoding, most people expect to be able to enter an address and have the map go there) and can usually be included in a simple, easy-to-understand way. I think you run into trouble (and usability issues) when you start adding toolbars and duplicating functionality in your app. Redlining is a different animal as I think it means different things to different people. On the whole, if you're asking people to annotate and/or edit maps/data, I would make that a separate app. Use a simplified, read-only app for public consumption and a more fully-featured (but still not an ArcMap clone!) for things like editing and making custom maps. Totally agree.  We ended up with the all in one app, but with config files to determine what layers/widgets load.  (?type=landdevelopment).  That way its one app to maintain, limitless config options. So on land development, you get zoning, etc and on utilities you get trash pickup.  Also means only one interface to learn/teach, but with customizable options. ... View more

I'm happy to hear that you're moving to using the ArcGIS API for JavaScript but I'd like to discourage you from trying to duplicate ArcMap in a browser. Web apps should not strive to duplicate heavyweight desktop clients, even if your goal is a light version. I would instead encourage you to build focused, targeted apps with a specific use in mind. Try to build apps that answers a specific question or addresses a specific problem rather than building something that is a tool for general analysis. While I agree with this both in principle (as a developer) and in theory, unfortunately it does not work in practice.  On mobile devices users are willing to tolerate a single use app because they are so fast and lightweight. However, on the web, they expect full functionality.  Can you imagine from a training standpoint: If you want parcels, open this webpage.  Oh you want to see Zoning, thats a different app.  Oh you want Utilities, app number 3. Measure, Redline, Geocode? apps 4 5 and 6. User = gone. Of course, as soon as we add it all to one app, you get complaints about speed. Our app is a slow all in one, so we developed a very light fast specific app.  Immediately requests starting pouring in to add everything we had removed to speed it up. Unfortunately, for the majority of our users, the specific question or problem they want answered is "how can i do everything that i can do on the desktop on the web for free" 🙂 Here is a link to our slow all in one. http://www.mymanatee.org/gisapps/mapviewer/ ...

Hi, I am trying to add a kml layer to my map. However, the control reaches onError handler and shows 'File not found. Wrong Url' error. The Url is correct and I can get back data if I use it on a IE browser. Why should the code fail with this error? Any input is appreciated. Our server isn't accessible from outside. If I see in developer tools where the url is appended to http://utility.arcgis.com/sharing/kml?url=myurl ==> this returns File not found error and I am sure Kml layer isn't getting loaded because of this. But, how should I fix this? Thanks! KML must be on a public server https://developers.google.com/maps/documentation/business/faq#intranet_kml How do I render KML files that are hosted on intranet sites on a map? The KmlLayer class that generates KML overlays in the Google Maps API uses a Google hosted service to retrieve and parse KML files for rendering. Consequently it is not possible to display KML files that are not hosted at a URL that is available publicly accessible, or that require authentication to access. If you need to develop applications that use KML files hosted on intranet sites we recommend that you either: Use the Google Earth API which supports client side parsing and rendering of KML. Render the KML on the client side by using third-party JavaScript libraries. As the KML file is analyzed by the browser, performance may be lower than by using the KmlLayer class. ... View more

I created a basic map displaying Rest Services A, B & C using the "ArcGIS Viewer For Flex Prerelease" GUI, then c/p the app directory to: https://mydomain.com/flexmap I then created a similar map using the JS API and hosted the web app here: https://mydomain.com/jsmap When the client visits the flex map, everything is fine, but when the JS map is viewed, Internet Explorer displays "IE has blocked this website from displaying content with security certificate errors". After the alert ribbon is clicked, you can choose "display blocked content" and everything works. What in the JS api would be causing this? here's how the api si referenced: <script type="text/javascript" src="https://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.8"></script> thanks! Are you connecting to a secure service? if so, you need to put a valid ssl cert on the server. It looks like flex is blindly trusting and invalid cert on the server (BAD) but javascript is not (GOOD). ... View more

I had tried queryTask - I am not even getting into the call back - not sure what is wrong with my query - here it is: getFeatures: function(){ var queryTask = new esri.tasks.QueryTask(sublayeritem.url);                                         var queryP = new esri.tasks.Query();                                         queryP.returnGeometry = true;                                         queryP.outFields = ["*"];                                         queryP.outSpatialReference = this.map.spatialReference;                                         queryTask.execute(queryP, dojo.hitch(this, "resultCallback")); }, resultCallback: function(featureSet) { } do you see the query (as a GET or POST) in firebug? ...

I never really had alot of luck with center and zoom.  I prefer to called setExtent explicitly. do you get the same error with map.setExtent(map.extent.centerAt(pt); map.setExtent(map.extent.expand(0.1)); if you do it this way it also explicity says use factor and cant be misinterpreted as a level from tiled (if you use a tiled basemap from the gallery or AGO, for example) ...

We have an application required to run on IE7 and we've encountered a problem with an event object passed into a function during a dojo.connect "onclick". evt.graphic.symbol.type is coming in as "not defined" in IE7, but works in Firefox. The code: dojo.connect(this.map,"onClick", function(evt) { if(evt.graphic.symbol.type == "textsymbol") {    // do something } else {    // do something else } }); Should this work in IE7? My guess is this is due to the fact that IE uses canvas and everything else uses SVG. if you alert evt.graphic.symbol i bet you get different results in IE and others.  YOu will have to do a dojo.isIE<9 and trap for canvas element or check dojox.gfx.renderer==="vml" and then do your event. ...
