There are two different ways that data can be gathered to be put in a GIS. An individual can get all the data information by actually making the calculations, measurements, readings, using tools to help them collect it, or they can try and get data that has already been gathered by someone else. Data Sharing is a very important tool in all the work revolving around GIS. It is so important because gathering your own data may mean that you get correct information, but it will cost you a lot of time and money. When using your own methods to gather data it can be quite costly. Data aquisition costs can account for up to 85% of the cost of producing a GIS. The opportunity to share data helps move things along.
Data Sharing is the practice of making scholarly research, data, or knowledge available to others. It is at the heart of many scientific studies. There are many written as well as unwritten rules to sharing data. Ultimately it is at the discretion of the person who collects the data to decide whether or not they will share. Many private companies like to keep their data secret so that they can make a profit or maintain an edge over their competition. In the scientific community, it is often looked down upon when data is withheld.
On August 9, 2007, the President of the United States of America (George W. Bush) signed the America Creating Opportunities to Meaningfully Promote Excellence in Technology, Education, and Science Act (America COMPETES Act). This act helped civilian federal agencies provide guidelines, policy, and procedures to help open the exchange of data. It promotes the sharing of data between agencies, the public, and policy makers.
This and various other acts help the sharing of data in many faucets. More open ideals on sharing data allows innovation, colaboration, and better use of ideas and information to improve the lives of all of those around us. Sharing data plays a huge role in what can be accomplished in a GIS. quote
