Spatial Data Acquisition, Display and Use

Humanity has used spatial data for many centuries begining with sea explorations in the 13-th century. The data, often displayed as navigation charts, were acquired with rudimental equipment. Technological advances were key in changing the use of map and surveyed data. In modern times, the great significance of land surveying and mapping processes lies in the ability to satisfy a diversity of user demands. In this fact also lies the justification for national and international policies to regulate outcomes and ensure that the skills and products will continue to exist as a public good throughout the generations.
