New look and banner maps

You will have noticed that the banner picture is now a dynamic map... The monsoon season has passed and the hurricane season is starting: So let's augment the previous image of dust cover with NOAA's wind speed map too, shall we?

But I simply used the "embed" feature of ArcGIS Explorer maps, available from other packages too, and reformatted the entire banner to accommodate that.

This came in especially handy for consuming web mapping services (those and many other specifications have grown since). But it gets trickier when it comes to reading from and writing to spatial databases generically. By that I mean not from the native application but from others', like with shape files.

Even more beautiful maps in current affairs

I'm baaack! Here is the web mapping service directly in ArcGIS Explorer (AGX). This was posted two weeks ago as a layer package on I wondered then why AGX would not accept OGC WMS services? While I was away ESRI Support responded with two caveats:
