question about shp2tile

[Zhonghai Wang]

Hi All,

with the shp2tile command, I get some strange results:

data -- forests.shp (includes 9638 polygons) -- only used for example

after performing the commands shp2tile, tile4ms and shptree, this time I
perform additionally the command shptreevis for each shapefile, and I get
the quadtree views for the shapefiles. When I open the forest_quad.shp and
overlay the tileindex_quad.shp on it with QGIS, the tileindex_quad.shp
covers only a small part of the whole forest map extent, and the returned
map image is rendered in the same way, forest covers only a small part of
the map extent.

P.S>I tile the shapefile without any additional parameters: shp2tile
forests.shp ff.shp  --  it gives 2*2 tiling

three pictures are enclosed in the attachment.

where:
1. quadtree.jpeg -- the quadtree shapefiles opened in QGIS;
2. map.jpeg -- map image rendered with TILEINDEX "tileindex" and TILEITEM
"LOCATION";
3. forest.jpeg -- forest area rendered with original forests.shp file.


thanks for any further info
