What's new in ArcGIS Mobile 10

The ArcGIS Mobile system has grown in many ways for the new release. There are new datasources, expanded spatial reference, new webservices, opportunities to customize the mobile application, and new developer platforms.

New data sources

At 9.3 the concept of a basemap was introduced to improve drawing performance, and provide additional map data support. With this release, the basemap feature has been expanded to include:

At 10, the new type of stored basemap is called Cached Tile basemap, which is created as a series of tile bitmaps which are drawn together like tiles on a floor. By having different groups of tiles for each desired map scale, the display can re-draw quickly, but only at the pre-set scales. The Mobile SDK has a new type of maplayer which is used to display this data on the mapcontrol.

Library changes

In ArcGIS Mobile 10, a new spatial reference and GPS library are included. The Spatial Reference library has been enhanced to support converting from one spatial reference to another. While the ability to display map data in many different spatial references was previously available, there was no way to perform conversions. The engine supports both Windows and Windows CE operation system. The engine was ported over from ArcGIS and it was the same engine used to support ArcGIS spatial reference system. There are two files, one is for Windows and one is for Windows CE. The spatial reference engine for Windows can be found in \ArcGIS\Bin\ESRIMobilePE.dll while the spatial reference engine for Windows CE is located in \ArcGIS\DotNet\WindowsCE\ESRIMobilePE.dll. The library is a native dll. It is accessed through SpatialReference class.

The GPSlibrary has been replaced with a new one written as a native library.

New stand-alone product install

At 10, ArcGIS Mobile is no longer part of the ArcGIS Server install, you can install and uninstall ArcGIS Mobile using its own setup. This allows for a focused setup process and a much faster install.

Integrated development environment changes

A new developer component, TokenCredenial, allows developers to add token based security to their mobileservice during development. Support for the WPF development environment has been added to allow developers to use this new environment. There is a new namespace, ESRI.ArcGIS.Mobile.WPF, which provides controls for developing Mobile SDK Applications.

New functionality added

The Mobile SDK has been expanded with two new namespaces; ArcGISServices.Geocoding and ArcGISServices. The support for SDCdata has been expanded to make this datasource a more useful part of the mobile map. The addition of renderers and datasets\datarows allow this dataformat to be used in queries.

New developer opportunities

The ability to customize the out-of the box applications provides a new opportunity for developers. The SDK can be used to write extensions or tasks that will plug into the mobile applications to provide additional functionality or tailor the application to the client's needs.

New namespaces

New GPS features and improvements

For GPS components the new rewritten library contains the same functionality, but improves the linkage between the Mobile SDK classes and the GPS receiver. New classes have been added to provide built in tools for GPS Construction using GPSAveraging or GPSStreaming. Another improvement for the GPSConnections and GPSDisplay is the implementation of PropertyChanged Event. This allows developers to catch individual property changes instead of generic GPSChanged types, which only happen when a new sentence is received.

For developers wishing to extend the GPS functionality, we have unsealed the GPSDisplay and Satellite classes. Now you can subclass these to add your own functionality, while leveraging our base features, instead of writing your own class completely.
