For those groups that are not familiar with high accuracy requirements, technology cannot be a substitute. In other words, if the foundation is not based on sound practices as generally utilized in the surveying profession, when the basics are advanced to higher levels of utilization, conclusions cannot be expected to retain the same level as accuracy. If data from different sources is combined, it does not increase the accuracy. In fact, if anything, it may decrease the accuracy. One problem that can surface however, is one of funds.
Budgets have a tendency to downgrade the accuracy levels.
Since other areas of expertise are required to develop, utilize and maintain an effective GIS, each component must reach for the highest levels of accuracy. Surveying is one of those fields in the many disciplines to be incorporated. The Professional Surveyor has the knowledge and skill for creating accurate and reliable GIS databases. A coordinated effort between those involved in the GIS and Professional Surveyors can be achieved by open communication and cooperation and the recommendation of utilizing the skills of the Professional Surveyor may be critical in the initial establishment of the GIS and the long-range value of what has been created. Since the end result may be far removed from the initial plans for the basic GIS, it is important that all phases of the GIS, from the beginning surveyor's measurements, to the interpretation of the data, must be achieved at the highest level possible.
