check out the jsfiddle link i posted in this thread you should be able to copy the code onto your own web server and view legend swatches (after updating the proxy reference) ... View more

for calculating "Zonal Statistics as Table" are you saying that you want the sketched polygon geometries to be appended to a static shapefile and used together as the input feature zone data? its pretty typical to run a geoprocessing service from a client web application with an input featureset of sketched graphics, but if you need to do the above i think you're on the right track with using python. your script (published as a geoprocessing service) would have to 1. accept the input featureset and append it to your static shapefile. 2. make sure the zones field for sketched features is populated appropriately 3. call the Zonal Statistics as Table tool. is creating a link to the output table for client download what you had in mind?  because i'm not sure how you could handle the information directly in the JavaScript application.  Also, you'll have to make sure you have the right extension licensing for ArcGIS Server to publish a GP service with a Spatial Analyst tool. ...

no worries! 🙂 specifying the projection for the map is something you do in our desktop software before you even publish a map service, so here are some links to our Desktop and Server help... once you have a service up and running, you should be able to build a simple javascript app like this sample. ...

i couldn't really speak intelligently about the Google Maps API, but using our JavaScript API it would be a pretty simple task to publish a map service with a polar projection and display it in a web application as either a cached or dynamic map service layer. ... View more

here is a list of projected coordinate system IDs... what do you mean "generate" a projection of a map?  typically we use the JS API to refer to a map service that already has a predefined coordinate system.  ArcGISDynamicMapServiceLayers can reproject on the fly.  ArcGISTiledMapServiceLayers cannot. you can use a geometry service to reproject a feature, if you're trying to do something else it would be helpful if you could provide some more specific details. ...

it'd probably be easier to just reference the JS API via SSL as well ie. https://serverapi.arcgisonline.com/jsapi/gmaps/?v=1.6 ... View more

i checked the following sample and it seems to display an ArcGIS Server service over a Google basemap without error. the Esri extension API is not compatible with Version 3 of Google Maps API.  see the following link for more info. ... View more

i'm pretty sure that the generic map.graphics layer always draws on top, but if you instantiate a named graphics layer instead you can take advantage of map.reorderLayers() (or just add the named graphics layer to the map before you add the featureLayer) to ensure that the featureLayer draws on top of the graphics layer. ...

yup.  that comes straight out of our help. based on changes mentioned above, it will probably be necessary to load additional modules and ensure your application waits for all modules to load before firing code in order to upgrade to version 3.x.  that being said, i haven't heard anyone say they had to rewrite existing application logic in order to upgrade. ...

jeff is correct.  right now some esri servers support CORS, and some don't. ... View more

whats keeping them from migrating to the newest version of our API? if you can't move to Dojo 1.7 and use a dgrid, you'd want to check out a sample like this. ... View more

the sample demonstrates functionality available at version 3.2 of our JavaScript API.  it uses a feature layer based on a 10.0 map service, but would work equally well with a 9.3 service. (just as an fyi, if you want to know the version of ArcGIS Server which is hosting a service, just navigate from its REST URL to the associated services directory (see examples below).  in the upper righthand corner of the page, the version of ArcGIS Server will be listed.) service in use http://server.arcgisonline.com/ArcGIS/rest/services/Demographics/USA_Median_Net_Worth/MapServer/4 REST service directory http://server.arcgisonline.com/ArcGIS/rest/services/ ...
