CGIS is providing geographic information systems (GIS), data mining, and application development services to lending organizations across the southeast. Our services are supporting marketing and appraisal departments in ways never before imagined, and perhaps most importantly freeing up human resources within the organization allowing them to redirect that work effort and leverage the data and information now being provided by CGIS.As providers of financial services, including loans for real estate, agriculture, rural homes, equipment, buildings and commercial operations, these organizations are very interested in tracking ownership of everything from large acreage tracts of land to smaller tracts that are classified agricultural. Information about such tracts of land, including those that have been sold in the last few years, is available to the public, but is often very time-consuming to find and extract into a format that is usable.
Completed tasks include the design of physical data models around required property search information, building SQL Server databases around those physical data models for storing the property search information, and developing and implementing Web-based portals for accessing, querying and analyzing the property search information. Our data portals are secure, contain a map window for displaying property location and condition, and provide critical ownership information to both marketing and appraisal personnel.
CGIS is also providing GIS support to meet specific needs within the appraisal departments of these organizations. Appraisers must keep a record of properties used for comparable sales and properties offered as collateral for a specific mortgage. In addition, there is a tremendous amount of available spatial information that if accessible can prove beneficial to their day-to-day business processes, making them more efficient in the use of their time and thus a greater asset within the organization. CGIS is responsible for master GIS map documents, including base map data, property feature and attribute data management, derivation of new feature and attribute data, and spatial data analysis (e.g. buffering, proximity analysis). Master map documents and associated spatial and tabular data is updated and distributed at regular time intervals to those who are authorized to use it.
Other GIS services being provided by CGIS include GIS interoperability, GIS training in the use of open source GIS software, and Web-based mapping solutions.
See What Our Customers Have to Say
The 2012 PGA Championship was searching for a unique solution on how to accurately present our hospitality packages in a more interactive fashion where our clients could literally picture themselves experiencing the hospitality products. The days of looking at pictures in sales brochures are limited, we needed something more dynamic and able to easily be shared on the web. Joshua and his team spent time listening to our ideas and created a solution from scratch showing exactly what we needed to help sell our inventory. His team’s patience, creativity, and ability to listen to our needs gives them my full recommendation. The 3-D models exceeded our expectations and provided us with a sales tool that we never had before to help us sell hospitality at the 2012 PGA Championship.
Our GIS project was admittedly complex and had an almost unruly amount of datasets to contend with. We were immediately impressed with Cornerstone GIS’s ability to help us understand what to expect throughout the development process and what would be required to complete the project. We became even more impressed with Cornerstone’s unwavering attention to detail and commitment to ensure we had an A+ project at the end of the day.
BES, Inc. has worked on numerous projects over the last four years with Cornerstone GIS. During this time they have demonstrated professionalism, integrity and perseverance. Joshua Chastain has demonstrated both a strong work ethic and is a dedicated team member. BES, Inc. will continue to pursue work with Cornerstone GIS as part of our long term strategic plan.
We were pleased to have Cornerstone GIS assist us with mapping existing and potential trails throughout the National Coal Heritage Area, which includes thirteen counties in southern West Virginia. Their technical work on this project was outstanding but we also appreciated the work they did collecting information at a series of public meetings and engaging community members in the process. The Cornerstone staff maintained constant communication with us throughout the project and were flexible in making last minute changes. We received an excellent final product that will be useful for years to come.
