Tralaine and Marinus now support AutoCAD 2000. Attention R14 Users: Download your FREE upgrade!
 New!
Marinus 2.02 (formerly DLG2DWG) converts USGS DLG
data to AutoCAD drawing file (i.e. .DWG) format. Marinus is capable of producing the
resulting data file in any defined coordinate system, regardless of the coordinate system
upon which the source data is based.
Trivia Answers:
1.Sophie
Germain. Carl Gauss
gave her number theory proofs high praise, an evaluation he repeated in letters to his
colleagues. Germain's true identity was revealed to Gauss
only after the 1806 French occupation of his hometown of Braunschweig. Recalling Archimedes'
fate and fearing for Gauss's
safety, she contacted a French commander who was a friend of her family. When Gauss
learnt that the intervention was due to Germain,
who was also "M. LeBlanc", he gave her even more praise. This trivia answer was found on the The MacTutor History of
Mathematics Archive Web Site: http://www-history.mcs.st-and.ac.uk/history/
2 The Gaussian Sphere (or the Gaussian Curvature) is the
sphere whose radius is the geometric mean of the meridional and transverse radii of
curvature at a specific latitude. Read more about the Gaussian Sphere in this month's GIS TIPS: Radians and Grads. Get the latest freebie: Ellipsoid Radii Calculator.
