previous e-mail, since you have your own datum shift parameters it is better to
write the full proj string, instead of using an epsg predefinition. Your
rotation angles are in radians but cs2cs expects arc-seconds. They become 1.04,
0.35, -3.08.<br>
According to the map projection definition you give, the command line should be

If a projection ID is not in the file the expected answer is the one you got.
It is not a configuration problem.<br>

font-size:12.0pt;">Dear Warmerdam and all members,<br>
<br>
I have been browsing and reading for a while to convert my coordinates with<br>
no hope until finding this Proj. 4.<br>
<br>
Kindly, I seek your support here ... I am using Linux Ubuntu to convert from<br>
long/lat (WGS84) to Cartesian (x/y) and vice versa. My need here is to get<br>
as accurate as possible results (cm-level if possible).<br>
<br>
I was reading this thread because I had a problem of getting a cs2cs results<br>
for espg=31495, while I could get them for espg=31468. But the conversion<br>
results with the later one were not accurate ~ almost 100 meters away.<br>
<br>
e.g.,: echo "13.755944 51.054555" | cs2cs +init=epsg:4326 +to<br>
+init=epsg:31468<br>
<br>
but when I change it to: echo "13.755944 51.054555" | cs2cs
+init=epsg:4326<br>
+to +init=epsg:31495,<br>
I get the message "projection initialization failure cause: no options
found<br>
in 'init' file".<br>
<br>
I tried to change something based on this thread, to make sure that my<br>
PROJ_LIB path is in place, but it seems I ruined everything. Afterwards, all<br>
espg zones gave the below error:<br>
"<br>
pj_open_lib(epsg): call fopen(/usr/local/bin/cs2cs/epsg) - failed<br>
Using from definition: init=epsg:31467<br>
Rel. 4.8.0, 6 March 2012<br>
<cs2cs>:<br>
projection initialization cause: no system list, errno: 20<br>
"<br>
<br>
I tried to "make uninstall" and "make install" but nothing
was fixed!!<br>
<br>
Here are more details about my project:<br>
<br>
My locations are in Dresden city, Germany, (DHDN4), and I have (I assume)<br>
all what is needed to get my coordinates converted accurately, but no idea<br>
how to process them in Proj. 4 (I am totally new here):<br>

<br>
Sorry for the long thread but did not want to miss any details, even in my<br>
first ever thread in this forum.<br>
<br>
I will be looking forward to reading form you.<br>
Best regards,<br>
Amro<br>
