Extract Data Widget does not work

City_of_Port_Angeles_GIS — Tue, 15 Feb 2011 19:04:44 GMT

Hi all,
When I try to use the Extract Data widget, I get a zipped file that has the necessary .dwg file but the drawing is empty when I open it in AutoCAD. Same thing happens if I extract to an ESRI shapefile. Does this widget require ArcGIS Server 10? I'm currently using 9.3.1.
Any help would be appreciated.
Billy

Yes, ArcGIS Server 10 is required.

Billy, if you get a zip file then your data extract widget is most likely pointing to a 10 server. If the file is empty, my first guess would be that there was no data to extract where you tried it. Try zooming out to the whole world (or whatever area you "know" has the data to be extracted).

To extract data from your own service, yes you will need ArcGIS Server 10, because the widget works with a "Clip and Ship" geoprocessing service that was new in "10".

The documentation has more details on the Data Extract widget:

Bjorn and Jon,
Thanks for the reply. Unfortunately, we can't upgrade to Server 10 until City Works does. Oh well.
When we do, this would be a very handy widget. Thanks again.

Hi;

I'm not able to select the layers at Data Extract Widget. Although I've setted the "layers to clip" on the model the "choice list" on rest appear empty. Thus the widget window dont show any layer to check.

Any idea??

Thanks

Is your geoprocessing service published as asynchronous?

Does your geoprocessing service expose at least the following three input parameters (with these exact names): Area_of_Interest, LLayers_to_Clip, Feature_Format.

From See http://resources.arcgis.com/en/help/flex-viewer/concepts/index.html#/Data_Extract_widget/01m300000039000000/

Hi Bjorn and others colleagues;

The answer for your two questions is yes. I tried a lot of parameters combinations but with no success. I see that others have in Layers_to_Clip at rest a "Choice List" that I dont have. Now in my last try I have added only one layer to model builder parameter (called "comunidades). Here is my rest:

Hi there,
I am trying to replicate the Clip and Ship Geoprocessing sample using my own data and I am having trouble getting the data to export. I am using ArcGIS Server 10.

I am getting a zip file exported and downloaded but the shapefile is empty although the .DBF does have the column names.

My data is held in Oracle in British National Grid (SRID 27700) and the map uses web mercator (102100). I am setting the geoprocessing output spatial refernce but this does not seem to affect anything.

gp = new esri.tasks.Geoprocessor("http://maps.lynxinfo.co.uk:8080/LIVE/services/UKOGL/UKOGLTools/GPServer/Extract%20Data%20Task");
gp.setOutSpatialReference({wkid:27700});

This is what I am doing to get the AOI for the Extract Data Geoprocessing Task:

function showTResults(results){
 dojo.forEach(results, function(result) {
      var graphic = result.feature;
   var fMarkerSymbol = new esri.symbol.SimpleMarkerSymbol(esri.symbol.SimpleMarkerSymbol.STYLE_SQUARE, 10, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([255, 0, 0]), 1), new dojo.Color([0, 255, 0, 0.25]));
      var fLineSymbol = new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_DASH, new dojo.Color([255, 0, 0]), 3);
      var fPolygonSymbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_NONE, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_DASHDOT, new dojo.Color([255, 0, 0]), 2), new dojo.Color([255, 255, 0, 0.25]));
      switch (graphic.geometry.type) {
    case "point":
           graphic.setSymbol(fMarkerSymbol);
        break;
        case "polyline":
           graphic.setSymbol(fLineSymbol);
  break;
        case "polygon":
            graphic.setSymbol(fPolygonSymbol);
        break;
        }
 map.graphics.add(graphic);
    });
 ext = esri.graphicsExtent(graphic);
};

Then passing it in like this:

var dlFormat = 'Shapefile - SHP - .shp';

 var params2 = {
  "Layers_to_Clip": clipLayers,
  "Area_of_Interest": ext,
   "Feature_Format": dlFormat
 }
 esri.show(loading);
 gp.submitJob(params2, completeCallback, statusCallback, function(error){
  alert(error);
 esri.hide(loading)
 });

Does anyone have any idea what I need to do to fix this?
