Making Web Maps
If you're using a WFS in ArcMap, it downloads and indexes ALL the data from the service. If you're connecting to a service that has ALOT of data (>?150,000 features), my experience is that you don't actually get all the data. One solution is to put a bounding box filter on the WFS connection to restrict the data request to the area you're actually interested in.
To do this, when you set up the WFS connection properties, and are in the 'Parameters' dialog (which you'll need to do to select the feature type from the service), put an XML bounding box filter expression in the 'XML Filter Expression'
here's a bounding box filter that works (WFS 1.0.0):
It is built from the ground up to work efficiently and smoothly on both desktop and mobile platforms like iOS and Android, utilizing cutting-edge technologies included in HTML5 and CSS3. The focus is on usability, performance, small size, A-grade browser support, flexibility and an easy-to-use API. The OOP-based code of the library is designed to be modular, extensible and very easy to understand.
