Now that you have a GIS System that is manag- ing all of your current activities you need to create a way to get your Historic Surveying Information into your GIS. In order to tackle this task we will need to divide your Historic Data into two different categories: “Before GIS” and “After GIS,” as the way that each category will be handled is different, but both methods will involve a process known as hyper linking.
Now that one third of the G I S System has been built it is now time to implement the rest of the system, the Mapping Engine and the Linkage. Building the Mapping Engine is going to take some exploration on the part is the GIS System developer, as the developer will have to search all available data sources and collect differ- ent data sets that will “Fill in the Picture” of the mapping interface. Building the linkage will require an analysis of the collected datasets for an appropriate method to bring the Database together with the Mapping Engine.
The myth that it would take too long to build and implement a GIS system for the Surveying Business to see any real benefit is based mainly in the idea that the Surveying Business must change the way the business is handled to fit with the GIS. Every Surveying business is managed in a different way, which provides a problem for the existing GIS industry; so they try to develop a “magic bullet” that handles all of the needs of every Surveying Business. Trying to provide a pre-built solution and expect the entire Surveying Industry to fall into rank has caused backlash and resistance to the implementation of GIS.Read More
efore dispelling this myth, we need to have a discussion of what makes up a robust GIS system. There are three parts: a database, a mapping engine, and nally a linkage. Each of these three parts is vital to making a GIS a viable solution for the needs of a land surveying business. And while the database and the mapping engine each have advantages to implementation, there is no magic until the linkage is brought to bear.
In this series of articles I plan to tackle the myths that I have encountered as to why others in the surveying industry have not developed a GIS system to make their lives easier. A list of some of the myths I plan to discuss are as follows:
With the required software and hardware investment, it is too expensive for a small or mid size surveying rm to build a GIS. The resources needed to start on the road of GIS will be surprising small when compared to the advantages that will be reaped from such a system. A thorough look at the software and hardware requirements can reveal many low cost—if not free—options to begin the framework of a GIS system.
A number of misconceptions about GIS exist among surveyors. Many believe that GIS is only for large companies that have many employees. Some thing the implementation cost is much too high to easily recoup the initial expenditure. Others believe that they don’t have the capability to pay someone to maintain a GIS, that it won’t help with the firm’s day-to-day operations, or that it won’t help them generate great profits. Coastal Surveying of Texas Inc. (CST) has proven all of these false.Read More
Our company, Coastal Surveying of TX, Inc., is located in a Galveston County, Texas, which is about 40 miles south of Houston. We wanted to have the capability of using a Real Time Network for our GPS collections, but we are far enough away from Houston that the major RTN network providers have not expanded their systems far enough South to cover the area that we work in. This left us with two choices; wait for the expansion of the existing networks to cover our area, if and when that might occur, or to build our own.
