[FreeGeoCZ] Prevod Lambert conformal do Krovaka

["fisu" <fisu AT seznam.cz>]

Zdravim,

 

nejsem uplne kovany GISar a souradnicovy prevadec a proto bych se chtel zeptat, jetsli byste mi nekdo neporadil jak prevest souradnice z Oblique Lambert conformal zobrazeni do JTSK, resp S42 (programove). Mam data z GRIBu (format souboru pro vymenu meteorologickych dat), projekce je popsana nize. Kdbyste nekdo mel nejaky napad a nebo mi poradil kam se podivat, budu vam vdecny.

Potrebuju ten prevod dat primo do kodu (VB.NET).

 

Diky

Lambert Conformal Secant or Tangent Cone Grids

Octet No.	Content and Meaning
7 - 8	Nx - Number of points along x-axis
9 - 10	Ny - Number of points along y-axis
11 - 13	La1 - Latitude of first grid point
14 - 16	Lo1 - Longitude of first grid point
17	Resolution and component flags (see Table 7)
18 - 20	Lov - The orientation of the grid; i.e., the east longitude value of the meridian which is parallel to the y-axis (or columns of the grid) along which latitude increases as the y-coordinate increases. (Note: The orientation longitude may, or may not, appear within a particular grid.)
21 - 23	Dx - the X-direction grid length (see note 2)
24 - 26	Dy - the Y-direction grid length (see Note 2)
27	Projection center flag (see note 5)
28	Scanning mode (see Table 8)
29 - 31	Latin 1 - The first latitude from the pole at which the secant cone cuts the spherical earth. (See Note 8)
32 - 34	Latin 2 - The second latitude from the pole at which the secant cone cuts the spherical earth. (See Note 8)
35 - 37	Latitude of southern pole (millidegrees)
38 - 40	Longitude of southern pole (millidegrees)
41 - 42	Reserved (set to 0)
