MapServer Export param 'Layers' Send Back All Data

GregCorradini — Mon, 17 Oct 2011 23:11:44 GMT

Hello,
I'm using the service and trying to get at only certain layers through the *export* operation:

http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/TaxParcel/AssessorsBasemap/MapServer

I only really want to see the TaxParcels (layerid 0) and not the BaseMap (layerid 2). But when I specify that in the Layers parameter I still get back everything:

http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/TaxParcel/AssessorsBasemap/MapServer/export?bbox=-83.3136869761022%2C42.5570588526199%2C-83.3023705323607%2C42.5683752963614&bboxSR=&layers=0&layerdefs=&size=&imageSR=&format=png&transparent=false&dpi=&time=&layerTimeOptions=&f=html

Is this normal behavior? Cause I've noticed this behavior in everything I tried on the example servers.

Greg,
http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/TaxParcel/AssessorsBasemap/MapServer is a cached map service, meaning you cannot turn on/off individual layers.

Right, but I'm still getting the same results for services like this one

Here is a link that displays only 1 layer - http://www.gulfofmexicoresponsemap.com/ArcGIS/rest/services/NOAA_WMS/MapServer/export?bbox=-10468656.2989378%2C3091334.37996061%2C-9042912.92968689%2C4113267.52279397&bboxSR=&layers=show%3A1&layerdefs=&size=&imageSR=&format=png&transparent=false&dpi=&time=&layerTimeOptions=&f=html

In the example that you posted you had an incorrect 'layers' parameter. Here is the API reference to correctly specify 'layers' parameter - http://184.73.201.18/ArcGIS/SDK/REST/index.html?export.html
