Inhalt:
Data is the essential ingredient for GIS, and many estimates put the cost of data acquisition at up to 80% of the total cost of the system. There are a number of ways of obtaining GIS data: creating one's own data, either directly or by contracting a third party to undertake a survey, purchasing existing data sets, digitizing remote data, converting existing paper maps, and utilizing data sets in the public domain.
