Hello to all,
I downloaded an OSM map file namely "india.osm.bz2".
I transported it in PostgreSQL database "gis" with the command :
./osm2pgsql -m -d gis india.osm.bz2
The above command resulted in the creation of the following tables filled with data in database "gis"
gis=# \d
List of relations
Schema | Name | Type | Owner
--------+--------------------+----------+----------
public | geometry_columns | table | anisha
public | planet_osm_line | table | anisha
public | planet_osm_point | table | anisha
public | planet_osm_polygon | table | anisha
public | planet_osm_roads | table | anisha
public | polygon_oid_seq | sequence | postgres
public | spatial_ref_sys | table | anisha
Now to convert the map data of one of the above tables in a shape file, I issued the following command:
pgsql2shp -f myfile gis planet_osm_line
Output:
Initializing... Warning, field addr:housenumber renamed to ADDR:HOUSE
Warning, field addr:interpolation renamed to ADDR:INTER
Warning, field admin_level renamed to ADMIN_LEVE
Warning, field construction renamed to CONSTRUCTI
Warning, field power_source renamed to POWER_SOUR
Done (postgis major version: 1).
Output shape: PolyLine
Dumping:
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
[126149 rows].
Question :
_______________________________________________________________________________________
How should I verify that the shape file resultant of the above command is a valid and uncorrupted one ?
_______________________________________________________________________________________
I am worried because the projection file namely "myfile.prj" contains the following !
PROJCS["WGS84 / Simple Mercator",GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID["WGS_1984", 6378137.0,
298.257223563]],PRIMEM["Greenwich", 0.0],UNIT["degree", 0.017453292519943295],AXIS["Longitude",
EAST],AXIS["Latitude", NORTH]],PROJECTION["Mercator_1SP_Google"],PARAMETER["latitude_of_origin",
0.0],PARAMETER["central_meridian", 0.0],PARAMETER["scale_factor", 1.0],PARAMETER["false_easting",
0.0],PARAMETER["false_northing", 0.0],UNIT["m", 1.0],AXIS["x", EAST],AXIS["y", NORTH],AUTHORITY["EPSG","900913"]]
The latitude/longitude values don't seem to be of India !!!!
Thanking you in anticipation,
Regards,
Anisha Kaul
