CyberGIS introduces a unique set of techniques that when implemented in a clientserver web environment will improve system-wide performance for web-based GIS applications.

This patent pending technique is prototyped using a COM-based software developed in Java that is easily manipulated through a graphical user interface (GUI).
CyberGIS has the flexibility to handle the processing and transmission of large volumes of variable size images, concurrently, in highly distributed architectural environments.
The ability to support concurrent user requests without proccss impairment and subsequent performance degradation can eliminate system bottlenecks and provide critical information to multiple users in a fraction of traditional response times.
CyberGIS can be applied to both raster and vector based data schema and in performance comparison tests handled up to 1.2 Gbyte airborne photos when standard methods failed. This is a scalable solution that can accommodate future growth in demand.

- Disseminate and share voluminous and heterogeneous data
- Improves system performance and response times
- Scalable
- Supports raster and vector data formats
- Lowers network load

Market Significance:

Geographic Information Systems (GIS) combine hardware, software, and procedures to capture, manage, manipulate, analyze, and display spatially referenced data.
Government agencies and private organizations alike often use GIS programs for everything from mapping to demographic information tracking. Use of GIS in the private sector is increasing, opening new markets for GIS vendors. A number of sectors can reap the rewards of GIS including financial institutions, law enforcement, healthcare, emergency services, research, consumer use, sales, and marketing. A flourishing GIS market has resulted in lower costs and ongoing enhancements in the hardware and software components of this technology. Additionally, services has grown to the second largest revenue generating market segment and accounted for 24% overall business revenues in 2002. As a result, such developments will lead to wider use of the technology throughout government, business, and industry. As a growing number of organizations outside the traditional boundaries of GIS are realizing that the high proportion of the data they have collected over the years has some kind of spatial dimensions, dissemination of large volumes of data coupled with mass user interations will require service providers to maintain a high level of service quality in order to compete.
