Som förläggare gav han ut ett flertal verk om navigation och besläktade ämnen.
Dutch cartographer and copperplate engraver based in Amsterdam. Famous for his marine maps in De Lichtende Colomne ofle Zee-Spiegel published 1654-88, and Zee-Atlas ofle Waer-Wereld published 1666-76. Goos also produced works on navigation.
Abraham Goos son, Pieter, continued and extended his father's business and became one of the group of well-known engravers of sea charts active in Amsterdam in the middle years of the seventeenth century. In common with Colom, Doncker and Jacobsz he published a pilot guide, the Zee-Spiegel, basing it on plates obtained from Jacobsz. This went through many editions in different languages under ...

WAESBERGHE, JOANNES JANSSONIUS VAN.
Död ca. 1680.
Holländsk bokhandlare. Han var från början boktryckare i Rotterdam, men kom till Amsterdam och gifte sig med en dotter till Joannes Janssonius (se denne). Efter svärfaderns död fortsatte han tillsammans med de övriga arvingarna dennes firma. Enligt signaturen på flera av kartorna samarbetade han en tid med engelsmannen Moses Pitt (se denne) mer om detta har inga ytterligare uppgifter hittats. Efter Waesberghes död verkar det som en del av kartorna övertagits av andra förläggare, däribland Peter Schenk (se denne) och Gerard Valk (se denne). Verksamheten drevs vidare som ett familjeföretag, åtminstone ett antal år in på 1700-talet.

Biografiska uppgifter:17 June 1714 – 4 September 1784
César-François Cassini de Thury (17 June 1714 – 4 September 1784), also called Cassini III or Cassini de Thury, was a French astronomer and cartographer.
Cassini de Thury was born in Thury-sous-Clermont (Oise), the second son of Jacques Cassini and Suzanne Françoise Charpentier de Charmois. He was a grandson of Giovanni Domenico Cassini, and would become the father of Jean-Dominique Cassini, Comte de Cassini.
In 1735, he became a member of the French Academy of Sciences as a supernumerary adjunct astronomer, in 1741 as an adjunct astronomer, and in 1745 as a full member astronomer.
In January, 1751 he was elected a Fellow of the Royal Society.
He succeeded to his father’s official position in 1756 and continued the hereditary surveying operations. In 1744, he began the construction of a great topographical map of France, one of the landmarks in the history of cartography. Completed by his son Jean-Dominique, Cassini IV and published by the Académie des Sciences from 1744 to 1793, its 180 plates are known as the Cassini map(fr).
The post of director of the Paris observatory was created for his benefit in 1771 when the establishment ceased to be a dependency of the French Academy of Sciences.
His chief works are: La méridienne de l’Observatoire Royal de Paris (1744), a correction of the Paris meridian; Description géométrique de la terre (1775); and Description géométrique de la France (1784), which was completed by his son ('Cassini IV').
César-François Cassini de Thury died of smallpox in Paris on 4 September 1784,
The Cassini projection is a map projection described by César-François Cassini de Thury in 1745. It is the transverse aspect of theequirectangular projection, in that the globe is first rotated so the central meridian becomes the 'equator', and then the normal equirectangular projection is applied.
In practice, the projection has always been applied to models of the earth as an ellipsoid, which greatly complicates the mathematical development but is suitable for surveying. Nevertheless the use of the Cassini projection has largely been superseded by the Transverse Mercator projection, at least with central mapping agencies.
Areas along the central meridian, and at right angles to it, are not distorted. Elsewhere, the distortion is largely in a north-south direction, and varies by the square of the distance from the central meridian. As such, the greater the longitudinal extent of the area, the worse the distortion becomes.
Due to this, the Cassini projection works best on long, narrow areas, and worst on wide areas.
