The ArcGIS server is an application installed on a server. The initial license fee is typically 25k. even thought the rendered image is in fact an image you can use draw tools to interact with the displayed features. What happens is it takes the geometry of the drawn object and performs a spatial query against the dataset on the server. The results are return and then you do whatever with the results... like draw graphics on the screen to show which features were selected or display tabular results in a table.  To answer your fist question you would want to do something similar like get the geometry of the drawn feature and use that as parameters to filter out the originally returned data. You could possibly create your own application to generate the image on the server but you would need to to extensive test make sure it lines up correctly. If you have the 25k to put towards the project then purchasing the ArcGIS server license would prove worth it. Also, you may want to look into getting an EDN license for ArcGIS server so you can test this out before you pay the big buck on ArcGIS Server. ... View more

also your JAVA implementation would be doing the work on the server side, versus this JavaScript implementation that would be doing the work on the client side and the browser being used would make a difference in performance as well. ... View more

You can use this API without having ArcGIS Server installed, if this is your case where you are using the API without an implementation of ArcGIS Server; then you won't be able to publish a map service. If you do have ArcGIS Server installed then you can add and display your data in an ArcMap document, publish it to your ArcGIS Server and then consume the published service in your web application. Here is a tutorial link for doing that. ArcGIS Help 10.1 Also, you may be able to publish the data to an ArGIS Online account and consume it from there, but I am less familiar with this process. Nevertheless, if you are unfamiliar with this process you may find it less troublesome to achieve your goal using the link I posted in my 1st reply. ... View more

are you using the ESRI.ArcGIS.ADF.ComReleaser to marshal  the search objects. If not that's likely your problem. Check out these to links they have examples and instruction on how to use it. ArcObjects 10 .NET SDK Help ArcObjects 10 .NET SDK Help ... View more

I'm assuming you are drawing graphics and not using a published service to render the image. Ideally you would want to use a published service and let a beefy server do the work. But this may not be possible if you have chosen to use graphics. Take a look at this link it is the ideal way of point clustering using graphics. Point clustering | ArcGIS API for JavaScript ...

You would normally control the column count for the legend with the highlighted control below but it's going to be tricky to do while passing to through ArcGIS server.Especially since the control is disabled when it is not loaded with a layer. Maybe do some trial and error with this. Or it may be better to just develop your own legend that is printed on a separate page that pulls it's data from the legend interface on your REST page. ...

I have successfully used the legend widget with map services that are 2 and 3 layer groups deep. What version of ArcGIS server are you using? I believe version 9.3 and below do not have the legend interface. If i remember correctly it wasn't introduced until 9.3.1. If you are at version 10 or above you can access the REST service for the published map service and navigate the legend link and see if the legend is being produced from ArcGIS server. ... View more

Looks like the code that you posted shows the part that is working, which is one raster at a time. I suggest posting the code that is causing issue. ... View more

when running function RasterToNumPyArray (in_raster, {lower_left_corner}, {ncols}, {nrows}, {nodata_to_value}) try setting the -3,40282e+038 for the nodata_to_value parameter. It could also be a product of the way the numpy creates it's arrays, by creating the array 1st with dummy values and then going and updating the values that correspond to the raster. ... View more

check your parameters, if your start contour level is not within the range of the DEM values and your interval to draw the contours from the start point also miss the values that fall in the range of the DEM then you would end up with an empty dataset. ... View more

James, The error indicates you are running the python script out of process. Could you try checking on the property of the script tool to run the Python script in process. I don't see anything that stands out for why it would fail out of process but this would be worth a try. Had similar error where checking the property of the script tool to run the Python script in process solved the problem. Thanks ... View more
