[GRASS-user] E00 import problem

[Markus Neteler]

Richard,

downloaded and tested:

# uncompress
e00conv dnnet.e00 24647.e00

# convert
avcimport 24647.e00 dnnet

# look at metadata:
ogrinfo -so dnnet arc
Had to open data source read-only.

states
Projection information for Russia
    Projection	LAMBERT
    Units	METERS
    Spheroid	CLARKE1866

So you cannot import this into a LatLong location but need to
create a Lambert projected location.

The metadata in the uncompressed E00 file contain:
PRJ  2
Projection    LAMBERT
Zunits        NO
Units         METERS
Spheroid      CLARKE1866
Xshift        0.0000000000
Yshift        0.0000000000
Parameters
 70  0  0.000 /* 1st standard parallel
 50  0  0.000 /* 2nd standard parallel
 110  0  0.000 /* central meridian
 0  0  0.000 /* latitude of projection's origin
0.00000 /* false easting (meters)
0.00000 /* false northing (meters)

With the Location manager, you will be able to define it.
The v.in.e00 will work as expected.
