hi Don,
I downloaded the roads.shp file from www.geotools.org.
I generated a spatial index from the roads.shp file as follows :
java com.bbn.openmap.layer.shape.SpatialIndex -c roads.ssx roads.shp
and
i also check using
java com.bbn.openmap.layer.shape.SpatialIndex -d -c roads.ssx
and it gives me the following output for the last line :
Record 825: 66850, 40 : 608450.91960898, 4924861.16290276, 608461.96373034,
4924891.45383137
I presume that is in decimal degree lat/lon data.
Then i modified the openmap.properties to include
shapePolitical.shapeFile=roads.shp
shapePolitical.spatialIndex=roads.ssx
But when i tried to display the roads.shp in Openmap, nothing was
displayed. Besides the roads.shp, I have also
tried many other shape files. All of them have the same problems.
Could you help me on this ? Thank you.
Regards,
Kwang Mien
