Hi,
I'm completly new to GIS and cartography, so, please, excuse if my
question is too stupid.
I'm particulary messy with datums and projections topics and with data
formats.
Anyway, I have a file with vector geographics data, and wish to convert
it into shapefiles and browse it
with mapserv.
The data I have use coordinates like
55.0195312500,34.9804687500;
55.0195312500,39.9902343750;
59.9853515625,39.9902343750;
59.9853515625,34.9804687500 (it is in Moscow, Russia) and somehow I know
that the WGS84
projection was envolved.
So, I created shapefiles with simple perl script (shapelib/Shape.pm). I
did not use any conversions
and insert these coordinates AS IS into shapefile.
Now, mapserv shows the map but all objects are too small, ~10000 times
smaller than actual objects
compared with scalebar.
I tried use different PROJECTION sections with no luck. I'm not sure if
I should right PROJECTION sections or I should transform coordinates
before insert it into shapefile. Actially I didn't see any visual
diffirences
with different PROJECTION sections at all.
I'm using mapserv 3.5, proj 4.4.5
mapserv -v
MapServer version 3.5 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP SUPPORTS=PROJ
SUPPORTS=TTF SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT INPUT=TIFF
INPUT=EPPL7 INPUT=JPEG INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE
Could you help please?
