ogrinfo show x y columns as strings

[Richard Duivenvoorde]

Hi list,

I have the following txt file that I want to use as a virtual datasource:

text,x,y
test,10,10
test2,11,11


Using a ODBC connection in Windows everything works fine:

ogrinfo ODBC:puntenlaagdsn testpoints.txt
INFO: Open of `ODBC:puntenlaagdsn'
using driver `ODBC' successful.

Layer name: testpoints.txt
Geometry: Unknown (any)
Feature Count: 2
Layer SRS WKT:
(unknown)
text: String (255.0)
x: Integer (10.0)
y: Integer (10.0)
OGRFeature(testpoints.txt):0
 text (String) = test
 x (Integer) = 10
 y (Integer) = 10

OGRFeature(testpoints.txt):1
 text (String) = test2
 x (Integer) = 11
 y (Integer) = 11



But putting everything to linux fails, because ogr(info) (with exactly
the same txt file) reports the x y columns as strings, giving a
featurecount of zero => no features on the map :-(

ogrinfo -ro -al ODBC:@puntenlaagdsn testpoints.txt
INFO: Open of `ODBC:@puntenlaagdsn'
using driver `ODBC' successful.

Layer name: testpoints.txt
Geometry: Unknown (any)
Feature Count: 0
Layer SRS WKT:
(unknown)
text: String (255.0)
x: String (255.0)
y: String (255.0)


Does anybody knows what's the problem?

Is it an odbc problem?

Who is responsible for 'typing' the columns in the txt file?

TIA

Richard
