I try to add a shp file with a line; things goes pretty well, but when i zoom in the line to some extent, the line just vanished, when i zoom out the line, it just appeared; i want the line always stay in my sight! i wrote the earth file like this:
<model name="world_boundaries" driver="feature_geom">
<features name="world" driver="ogr"> <url>E:/mapdata/shpFile/sdfgh.shp</url> <build_spatial_index>true</build_spatial_index> <convert type="line"/> </features>
<layout tile_size="500000" crop_features="true"> <level max_range="1e10"/> </layout>
<styles> <style type="text/css">
did i do something wrong, i will really appreciated if any one can correct me....
