GIS DataTypes in SQL Server 2008

Microsoft’s SQL Server 2008 offers new support for spatial data types that some analysts say should deliver a real boost to geospatial applications and data sharing.

Expected to ship in the third quarter, the new version of SQL Server will allow storage of spatial data — in the form of points, lines and polygons — in SQL tables. The software will also offer a set of functions to allow the manipulation of this data and new spatial indexes to support the execution of these functions.

What is GIS?

geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.

Why GIS?

GIS allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts.

A GIS helps you answer questions and solve problems by looking at your data in a way that is quickly understood and easily shared.

GIS technology can be integrated into any enterprise information system framework.

A GIS can be viewed in three ways:

1. The Database View

2. The Map View

3. The model View
