Jim, I don't really have a good answer why you're seeing offsets. We can see some offsets too (on the order of 5m) in our imagery basemaps when comparing some control points from here http://www.linz.govt.nz/. With other points, we have perfect alignment. We did some visual comparisons based on some descriptions we found, like in the attached file. In some instances, Bing Maps appears to be correct, where our imagery is  off, but it could be related to the particular area we're looking at. Mike ... View more

It is not possible to group layers in a web map. Nice idea though. Thanks, Mike ... View more

Can you share your KML file here so we can take a look? Thanks, Mike ... View more

Yes you can show multiple images in your popup. The way you do this is your data needs to contain the image you want to display. Here's an example of a CSV file that can be added to a map. It has two attribute fields, called photo1 and photo2 that contain the URL to images. Name,Latitude,Longitude,photo1,photo2 Hospital,34.038344,-117.206536,http://www.esri.com/data/graphics/basemaps1.jpg,http://www.esri.com/data/graphics/imagery4.jpg Supermarket,34.049054,-117.197436,http://www.esri.com/software/arcgis/arcgisonline/graphics/basemaps/world_imagery.png,http://www.esri.com/software/arcgis/arcgisonline/graphics/basemaps/world_street.jpg In the Configure Popup option accessed from the layer, you can add images at the bottom. You would add two images and use the photo1 and photo2 fields as the URL (Click the + sign next to the type in field). In this example, the attributes, photo1 and photo2, contain the full URL to the image. Alternatively, if all images were stored at the same location, the field might simply contain the image name, and the rest of the URL could be hard-coded in the URL field when defining the image, like this: http://www.esri.com/graphics/{photo1} Where the value of the attribute for the record would be substituted for the field reference, {photo1} Hope this helps, Mike ...

Jim, Are you seeing the 10m shift when displaying in ArcGIS Desktop? Or in ArcGIS.com map viewer? Or both? Thanks, Mike ... View more

Yes, you can add more than one image. Under the Popup Media section, click the Add button for each image you want to add... Thanks, Mike ... View more

If you've directly uploaded a shapefile, CSV or other data directly into the map, then is no way to update the layer. You will need to remove the layer from the map, then add the new one. The workflow we will support in the future is to allow you to make a hosted map service out of your data as part of a subscription to ArcGIS Online. In this case, the data will not reside in the map but will be referenced by the map. Thus, if the data changes, it will be reflected in the map. Thanks, Mike ... View more

Well, there is some rounding going on during conversion, but this offset seems too big. Do you have ArcGIS Desktop? When you display the shapefile in desktop over the same basemap data, do you see the same offset? Can you share your shapefiles with us? Both the original and transformed versions? Perhaps you can clip out a small piece of it if the data is large. Thanks, Mike ... View more

Because WMS is a service, there are no size restrictions. Are you seeing some error message? Are you sure the WMS services are operational? Perhaps you can share the URL to those WMS services. Thanks, Mike ... View more

it's probably best to transform your data into WGS84 Web Mercator Auxiliary sphere first. Thanks, Mike ... View more

What kind of data are you adding to your map? Thanks, Mike ... View more

Images have to be on the web already. It is possible to generate a link to the image based on attribute field values in your data. For example, you might form an expression that looks like this: http://some.com/images/{field with image name} When you add the image to the popup, you'll see a plus sign button that lets you choose from your attribute fields and substitute in an attribute value like the above example. Thanks, Mike ... View more

Yes, you are on the right track. Here's a link you can look at http://www.esri.com/data/basemaps.html I'd suggest you contact your distributor. Thanks, Mike ... View more

The queries ArcGIS.com sends to your server are failing. I did a little more investigating and found this forum post that discusses the particular error I'm seeing ("Unable to perform query.  Please check your parameters"). http://forums.esri.com/Thread.asp?c=158&f=2399&t=263435#810143 There is a reference to SP1 having a fix for the problem. Based on the date of the forum posts, that would appear to be 9.3 SP1. You can find the download here. http://resources.arcgis.com/content/patches-and-service-packs?fa=listPatches&PID=66 In short, you need to upgrade your ArcGIS Server in order for the popups to work in ArcGIS.com.

Likely, your map is too big for the web browser. Have you added more than one layer to your map? Even though you adhere to the 1000 feature limit, some web browsers can't handle drawing all of the features. From the symptoms you describe, I would guess that you are using Internet Explorer version 8 or earlier. But, all web browsers will start to get overwhelmed if you try to add lots of layers to them. You can try using a different web browser, like chrome or firefox. If you're already doing that, you can try generalizing your features before you add them to a web map. Polygon and line data often have a lot of vertices, and these are all drawn by the web browser. Often, you can generalize the data without losing precision. If you share your map with everyone then post a link to it, I can look at it. Thanks, Mike ... View more
