First of all, I am fairly new to OpenMap and GIS in general so please
let me know if I am off-base here.
However, I recently upgraded to a newer version of OpenMap (4.6.5) and
found that the spatial index file is no longer created automatically (if
missing) and is instead created in memory.
This causes my application to produce the "Creating spatial index file:
" message, although no file is actually created in the directory with
the shp file.
The documentation for the SpatialIndex class requires only two arguments
to create the ssx file manually; however, SpatialIndex.java is looking
for 3 args.
>From OpenMap API
----------------------
java com.bbn.openmap.layer.shape.SpatialIndex -c file.shp
Creates spatial index file.ssx from shape file file.shp.
>From SpatialIndex.java
----------------------
public static void main(String argv[]) throws IOException {
int argc = argv.length;
if (argc == 0) {
// No arguments, give the user some help
printUsage(System.out);
System.exit(0);
}
if (argv[0].equals("-d")) {
if (argc == 2) {
String name = argv[1];
SpatialIndex si = new SpatialIndex(name);
si.dumpIndex(false);
} else if ((argc == 3) && (argv[1].equals("-b"))) {
String name = argv[2];
SpatialIndex si = new SpatialIndex(name);
si.dumpIndex(true);
} else {
printUsage(System.err);
System.exit(1);
}
} else if ((argc == 3) && argv[0].equals("-c")) {
String shapeFile = argv[1];
SpatialIndex.FileIndex.create(shapeFile);
} else {
printUsage(System.err);
System.exit(1);
}
}
------------------------------------------
Finally, I used a dummy value as a placeholder for the third arg and
the ssx file was created successfully.
java com.bbn.openmap.layer.shape.SpatialIndex -c file.shp dummyvalue
Is this a known issue and if so, has this been address in the next
release?
Regards,
Will W.
