Norge (airship)

The Norge was a semi-rigid Italian-built airship that carried out what many consider the first verified overflight of – and the first verified trip of any kind to (see below) – the North Pole on 12 May 1926. It was also the first aircraft to fly over the polar ice cap between Europe and America. The expedition was the brainchild of polar explorer and expedition leader Roald Amundsen, the airship's designer and pilot Umberto Nobile and American explorer Lincoln Ellsworth, who along with the Aero Club of Norway, financed the trip which was known as the Amundsen-Ellsworth 1926 Transpolar Flight.

Design and development

Norge was the first N class semi-rigid airship designed by Umberto Nobile and its construction started in 1923. As part of the selling contract [as the Norge] it was refitted for Arctic conditions. The pressurised envelope was reinforced by metal frames at the nose and tail, with a flexible tubular metal keel connecting the two. This was covered by fabric and used as storage and crew space. Three engine gondolas and the separate control cabin were attached to the bottom of the keel. Norge was the first Italian semi-rigid to be fitted with the cruciform tail fins first developed by the Schütte-Lanz company.

Norge 1:50000

Norge 1:50 000 (Norway 1:50 000) is the main series of 727 topographical maps in 1:50,000 scale that cover the entire mainland area of Norway and proximate islands. The civilian designation is Norway 1:50 000 and the military designation is M711.

The military series includes 727 maps. The production of the map series was begun in 1952, and the series was completed for whole Norway in 1988. The maps are subject to ongoing revision, and about 60 maps are issued in new release each year. From 2012, a civilian series printed on plastic sheets on both sides and in a larger format were produced. Each map sheet is now equivalent to four different maps in the military series. The civilian series include 212 different maps.

Statens kartverk (Norwegian Mapping Authority), the governmental cartography office, is responsible for updating and maintaining the maps. The geodetic datum of the series is EUREF89 (European Reference Frame 1989), which is approximately equal to WGS84 (World Geodetic System 1984). The maps are in full color, complete with place names and political boundaries. Contour line spacing is 20 meters (66 ft), and the maps are usable for hiking and other navigation.

Artà

Coordinates: 39°42′N 3°21′E / 39.700°N 3.350°E / 39.700; 3.350

Artà is one of the 53 independent municipalities on the Spanish Balearic island of Majorca. The small town of the same name is the administrative seat of this municipality in the region (Comarca) of Llevant.

Population

In 2008 the municipality of Artà had a population of 7,113 recorded residents within an area of 139.63 square kilometres (53.91 sq mi). This equates to 50.9 inhabitants per km². In 2006 the percentage of foreigners was 13.2% (890), of which Germans made up 3.9% (262). In 1991 there were still 136 illiterates in the municipality. 1,292 inhabitants had no education, 1,675 only a primary school certificate and 1,210 had secondary school leaving certificates. The official languages are Catalan and Spanish (Castilian). The Catalan dialect spoken on the island is known as Mallorquí.

Geography

Location

Artà lies in the northeast of the island of Majorca, around 60 km from the island's capital of Palma. The Massís d’Artà, the highest and most compact massif in the eastern mountain chain of the Serres de Llevant, occupies more than half the area of the municipality. The municipality is located on the western part of peninsula of Artà and is bordered in the west by the Bay of Alcúdia (Badia d’Alcúdia), and in the north by the Mediterranean sea where its coast lies opposite the neighbouring island of Minorca. The coast of Artà stretches for 25 kilometres and, so far, has escaped being developed. Particularly noteworthy are the beach and sand dune formations of sa Canova d’Artà, the flat coastal strip near the settlement of Colònia de Sant Pere, the high rocky coves of the Cap de Ferrutx and a large number of smaller bays that extend from s’Arenalet des Verger to Cala Torta.

ART image file format

ART is a proprietary image file format used mostly by the America Online (AOL) service and client software.

Technical details

The ART format (file extension ".art") holds a single still image that has been highly compressed. The format was designed to facilitate the quick downloading of images, among other things. Originally, the compression was developed by the Johnson-Grace Company, which was then acquired by AOL. When an image is converted to the ART format, the image is analyzed and the software decides what compression technique would be best. The ART format has similarities to the progressive JPEG format, and certain attributes of the ART format can lead to image quality being sacrificed for the sake of image compression (for instance, the image's color palette can be limited.)

Usage by AOL

The AOL service used the ART image format for most of the image presentation of the online service. In addition, the AOL client's web browser also automatically served such images in the ART format to achieve faster downloads on the slower dialup connections that were prevalent in those days. This conversion was done in the AOL proxy servers and could be optionally disabled by the user. This image conversion process effectively reduced the download time for image files. This technology was once branded as Turboweb and is now known as AOL TopSpeed.
