Karl Kořistka was a Czech geographer, cartographer and professor. Kořistka studied geography and mathematics in Vienna, at an early age became a student at the school of mining and forestry at Banská Štiavnica. In 1851, he became professor of mathematics and geodesy in the German polytechnical school at Prague, he exerted a wide influence in the development of the professional schools of Austria. He was much occupied in orographical and hypsometrical studies and explored several of the mountainous regions of Europe, where he obtained a large number of levels and heights. From 1867 to 1869, he was a representative in the Vienna Reichsrat. Besides numerous memoirs written in German and in French, he wrote for many reviews and journals. Among his principal works may be mentioned: Studien über die Methoden und die Benutzung hypsometrischer Arbeiten Die Markgrafschaft Mähren und das Herzogtum Schlesien in ihren geographischen Verhältnissen Hypsometrie von Mähren und Schlesien Der höhere polytechnische Unterricht in Deutschland, der Schweiz, in Frankreich, Belgien und England Die Hohe Tatra Das Mittel- und Sandsteingebirge in Böhmen Das Iser- und Riesengebirge Verzeichniss der trigonometrischen Höhen von Böhmen.

Next Generation Data Communications, an element of the Next Generation Air Transportation System, will reduce controller-to-pilot communications and controller workload, whilst improving safety. In the current United States National Airspace System, all communications with airborne aircraft is by voice communications. Aircraft route of flight revisions must be communicated through multiple change-of-course instructions or lengthy verbal reroute instructions, which must be repeated; the use of voice communication is labor and time intensive and will limit the ability of the Federal Aviation Administration to meet future traffic demand in the United States. Adding air-to-ground and ground-to-ground data communications will reduce controller-to-pilot communications and controller workload; the data communications will enable ground automated message generation and receipt, message routing and transmission, direct communications with aircraft avionics. Data communications will be an additional means for two-way exchange between controllers and flight crews for air traffic control clearances, advisories, flight crew requests and reports.
The majority of communications will be handled by data communications for appropriately equipped ground and airborne stations. Data communications will enable air traffic control to issue an entire route of a flight with a single data transmission directly to the aircraft's flight management system. NexCom will be an eventual replacement for the existing Future Air Navigation System, used by transoceanic commercial airliners. Voice communications contribute to operational errors due to miscommunication, stolen clearances and delayed message transfers due to radio frequency congestion. Data communications will enable air traffic controller productivity improvements and will permit capacity growth without requisite growth in costs associated with infrastructure equipment, maintenance and training; as a result, the resources required to provide air traffic management service per aircraft operation will decrease. The use of real-time aircraft data by ground systems to plot 4-dimensional trajectories, perform conformance management, will shift air traffic operations from minute-by-minute tactical control, to more predictable and planned strategic traffic management.
