Thanks Jackie, another step is done ...
I run gdalinfo on my GeoTiff file getting this result:
Driver: GTiff/GeoTIFF
Files: myfirstimg.tif
Size is 450, 532
Coordinate System is `'
Origin = (497564.606297405260000,5061891.429550633800000)
Pixel Size = (0.338666666667020,-0.338666666667020)
Metadata:
TIFFTAG_XRESOLUTION=75
TIFFTAG_YRESOLUTION=75
TIFFTAG_RESOLUTIONUNIT=2 (pixels/inch)
Image Structure Metadata:
INTERLEAVE=PIXEL
Corner Coordinates:
Upper Left ( 497564.606, 5061891.430)
Lower Left ( 497564.606, 5061711.259)
Upper Right ( 497717.006, 5061891.430)
Lower Right ( 497717.006, 5061711.259)
Center ( 497640.806, 5061801.344)
Band 1 Block=450x6 Type=Byte, ColorInterp=Red
Band 2 Block=450x6 Type=Byte, ColorInterp=Green
Band 3 Block=450x6 Type=Byte, ColorInterp=Blue
In the Feature Source XML editor I have:
<?xml version="1.0" encoding="utf-8"?>
<FeatureSource xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xsi:noNamespaceSchemaLocation="FeatureSource-1.0.0.xsd">
<Provider>OSGeo.Gdal</Provider>
<Parameter>
<Name>DefaultRasterFileLocation</Name>
<Value>C:\Documents and
Settings\User\Desktop\GeoTIFF\myfirstimg.tif</Value>
</Parameter>
<SupplementalSpatialContextInfo>
<Name>Default</Name>
<CoordinateSystem>LOCAL_CS["*XY-MT*",LOCAL_DATUM["*X-Y*",10000],UNIT["Meter",
1],AXIS["X",EAST],AXIS["Y",NORTH]]</CoordinateSystem>
</SupplementalSpatialContextInfo>
</FeatureSource>
Should I modify this? And how (with the info from gdalinfo)?
thanks
