Step 5: Convert _xy.dig files to (longitude, latitude) coordinates

You can use my program Projector on any Windows computer. Projector will read a .dig file and produce: (a) a new .dig file with the same shapes in another coordinate system, and (b) an .ai (Adobe Illustrator) graphics file to display the results. Projector will give you an opportunity to describe the projection of the base map that you digitised from (type of projection, standard parallels [if appropriate], etc.). The "projection point" is any point on the map where there is no distortion: for a conic projection it would lie on a parallel mid-way between the standard parallels; for a Mercator projection it would lie on the standard parallel or meridian, etc. After you have specified the map type and projection point, you go on to describe your Cartesian (x, y) system by giving the coordinates of the projection point in the (x, y) system, and the azimuth of your +y axis at this point (relative to local North). Note that the 4 questions that refer to the "new .ai plot" are discussing an Adobe Illustrator plot that will be created by Projector, not one that already exists.

MAP PROJECTION
SOME OR ALL OF YOUR INPUT FILES ARE IN FLAT-EARTH (x,y) FORMAT.
(The alternative would be all in round-Earth (lon,lat) format.)
Your digitised (x,y) data are in units of: meters
The x value you want at the center of new .ai plot is: 9.100E+05 meters
The y value you want at the center of new .ai plot is: 5.500E+05 meters
In new .ai plot, the +x axis will be rotated: 0.0 degrees
counterclockwise with respect to the horizontal/right direction.
Map projection used to create (x,y) data: Lambert Conformal Conic
Map scale for new .ai plot (at projection point) is 1: 1.000E+07
Radius of planet, in meters: 6.371E+06
Longitude of projection point (degrees, East = +): -12.000
Latitude of projection point (degrees, North = +): 36.000
Longitude of axis of cone (East = +): 0.000
Latitude of axis of cone (North = +): 90.000
Gap between 2 standard parallels: 30.000 degrees
At the projection point, your (x,y) system has x = 8.732E+05 meters
At the projection point, your (x,y) system has y = 5.041E+05 meters
At the projection point, the azimuth of your +y axis is: 0.0 degrees
