Читать книгу Geography For Dummies - Jerry T. Mitchell - Страница 113

Map-making technology has come a long way from chiseling on stone, through ink on papyrus, through pen on paper splayed across a drafting table, and into the modern world. In the past three decades we have seen a revolution, a geospatial revolution, in how Earth data is collected, measured, and analyzed. That last part — analysis — is crucial. Data analyzed becomes information. Information can be acted on. This action takes the form of problem solving. And with this geospatial revolution, we are acting faster, more accurately, and hopefully for the betterment of all people than ever before. Three of these technologies — separate but integrated — are geographic information systems (GIS), global positioning systems (GPS), and remote sensing.
