The program designs to video and exports the file *.dxf of the world, of the state or of the states selected in the select projection and with the suitable parameters.For the states of Russia the data are in rectangular coordinates, they therefore am visible only through the Conic Projection of Lambert (Parameters not modifiable). Also for the Antarctica and Heard and McDonald Islands the data are in rectangular coordinates it therefore is visible only through the Projection Azimuthal Polar Stereografica (Parameters not modifiable).

30 projections, direct and inverse, are now available, the program is always in continuous amelioration

The spheroid for the data is  Clarke 1866.

You can select a Projection or modify the actual Projection
ATTENTION :When you convert the representation of a State or more States from
any type of Projection to the projection UTM the represented zone will be centered
on the central meridian

ATTENTION : With the Projections UTM and Polyconic you must to remain
always near to the Central Meridian

It allows you to design on the video the world or the State that comes selected

4ab) Add States or Country

It allows you to add on the video the State that comes selected, usually bordering with that visualized.

4c) End

It finishes the program

5a) Origin of projection center

Fix the longitude and/or the latitude of the Center of Projection. For many projection is possible modify
only the longitude. For the 2 interrupted projections the longitude is fixed to 0°.0000 and is not
modifiable. For the U.T.M projection. the program after have read the data fixed automatically the
central zone of the State

It modifies the projection of the state to video with the new parameters.

Initially the values fixed for the Longitude = -3°.0000 and for the Latitude = 0°.0000 Zone = 30

5b) False East/ North

Fix the East coordinate and North of the center of projection, it modifies the coordinates of the points
of the projection on the video according to the new data. For the U.T.M projection. the coordinate
False East comes fixed to 500000 m. and is not modifiable, the coordinate False North comes fixed to 0.

For the other Projections Initially the values fixed for the False East North are null

5c) Parallel Standard/ Parallels

Fix the values of the latitude of the parallel or of the standard parallels.

Values initially fixed for the varied projections:

Conic of Lambert: 1st [parallel]= 20°.0000 2nd [parallel]= 40°.0000

All the files will be saved in the directory of SetUp.

WARNING : Assume decimal point.

7a) Enlarge

After have done this choice the menů will be checked, clikking on the monitor the draw will be magnified on the basis of the select scale factor (Factor+/).

7b) Reduce

After have done this choice the menů will be checked, clikking on the monitor the draw will become smaller
on the basis of the select factor (Factor+/).

7c) Factor+/

Factor in [km] that determines as the draw  becomes + or - big

7d1) All

It shows the State and the Graticule

7d2) Window

You comes magnified the zone framed on the monitor with this operation: mousedown on the first point of the monitor  move the mouse up to the desired point and finally mousedown

7d3) Previous

It shows the previous image

You comes move the drawing on the monitor with this operation: mousedown on the first point of the monitor move the mouse up to the desired point and finally mousedown

You comes calculate and draw the Ortodromica between two points with this operation: [mousedown] on the first point of the monitor move the mouse up to the desired point and finally [mousedown]
The calculus of the Distance fails (Failed Distance) if the difference between the longitudine1 and longitudine2 is> Pi ( 180° ) or the distance crosses the meridian 180°/ -180°

You comes calculate and draw the Lossodromica between two points with this operation: [mousedown] on the first point of the monitor move the mouse up to the desired point and finally [mousedown]

7h) Ellipse of Distorsion ( Tissot's Indicatrix )

It draws circles with 300 km of radius.
The centers are to interval of 12° of Longitude and 18° of Latitude.
Each circle is definite from points to interval 15° of which we calculate Longitude and Latitude.
Subsequently we convert these points in X and Y on the interested projection. Uniting the points
you'll have the circle or the ellipse that has the characteristics of deformation of the projection
in the about of that point. If the indicatrix is a circle ( at a given point P ) then the map is conformal,
( angle preserving )  at P , otherwise the main axes of the ellipse give the directions of maximal and
minimal length distortion. If all the indicatrices, though they of different shape, have the same area
the map is Equal-Area.

ATTENTION: Only for the Graticule / DeltaLon = 12° .

Do you want to know where some cities of the world are found ?
You’ll draw all the cities of the states represented in projection.
