Hi,

I found some coordinates here, the official ones of kosovo , but they are
not in standard format.
I know there must be a way to do this :

1. can you help me transform them?
2. can someone do this?

Transformation of the ETRS89 coordinates into the new Gauss-Krüger
coordinate
system using program GEOREF. (File PROJNEU.PRN)

n New KOSOVAREF01 based on EUREF
http://www.fig.net/commission7/france_2004/papers_am/ts_10_1_meha_ppt.pdf

The state coordinate system of the Republic of Kosova (KOSOVAREF01) was
defined on
year 2001, based on ETRS89 datum and Gauss-Krüger projection with 1dm/km
negative
linear deformation along the central meridian (21E) and 7500000m false
easting. Due to
small area of Kosova, all territory projects with negative value in which
the largest linear
deformation (LD) is -10cm/km, i.e. the mean linear deformation (MLD) is
8.7cm/km.
In efforts for finding of coordinate system with smallest LD, Gauss-Krüger
projection with
scale factors 0.99996 and 0.999967, as well as without negative LD
(tangential case) were
researched also. In first variant (0.99996) the maximum LD is 4cm/km in
which 2.93cm/km is
the MLD, the second option (0.999967) provides the largest LD 4.6cm/km with
MLD
2.46cm/km, and Gauss-Krüger projection in tangential variant gives the
better MLD
(1.3cm/km) in which the largest LD is 7.9cm/km.
Due to configuration of the territory of Kosova, Lambert conic conformal and
stereographic
projections are probably the suitable as most appropriate state map
projections. UTM
projection as international has been utilized also.
In a stereographic tangential projection the largest value of LD is
4.18cm/km, in which case
the value of MLD is 1.17cm/km. With the target to reduce the deformations in
half value, due
to the difference distances of extreme points from the central point,
-2.1cm/km (0.999979)
and -1.9cm/km (0999981) LD in central point were used as extended options of
stereographic
projection. In first case the maximum LD is -2.1cm/km, in which the MLD is
1.08cm/km, as
well in a second effort, the biggest LD is 2.28cm/km with 0.94cm/km MLD.
During projecting of the territory in Lambert conic conformal projection, in
tangential case
the largest LD is 7.69cm/km, in which MLD of the whole territory is
1.15cm/km. Using of
negative LD from -3.8cm/km (0.999962) gives the interval of deformations
from -3.8 to
3.89cm/km with 2.85cm/km MLD in whole territory.
Because of the small area of Kosova, utilization of UTM projection provides
very large LD,
i.e. in interval between -39.21 to -40dm/km. MLD in all territory is
39.87cm/km.
Based on upper results, most appropriate state map projection of the
Republic of Kosova for
local use is Stereographic projection with scale factor 0.999979, but
utilization of UTM
projection for international use is irreplaceable.

Can someone decode that?
