<br clear="all"><div>how to visualize vector/raster from directly from GRASS database?</div><div><br></div><div>I am building webGRASS. for that I linked GRASS GIS all libraries to my application without any wrappers..</div>
<div>Now I can execute any grass command online. But for rendering I use OpenLayers. I want to change OpenLayers and use a WPaintWidget to draw raster and vector data</div><div><br></div><div>I can make this happen in this way</div>
<div>[1] call d.vect which will call v.out.ogr and create a gml file --> display gml on OpenLayers.Map</div><div><br></div><div>Now I want to reduce the overhead by spawning different process like d.vect --> v.out.ogr --> gml -->openlayers</div>
<div>I need rendering this way</div><div><br></div><div>[2] Read GRASS data directly from database (points/line/polygon for vector and image pixel values from GRASS raster format</div><div>so the chain will be</div><div>
GRASS Raster data --> (image pixel values) MyNewMapCanvas</div>
<div>GRASS Vector data --->(points/lines/polygons) MyNewMapCanvas</div><div><br></div><div>The reason behind my need is that on web it will increase speed and efficiency when we read data from GRASS database directly</div>
<div><br></div><div>All I want to do GRASS GIS core language C/C++ to make a web application</div><div><br></div><div>it is possible because I am linking my website with required grass libraries (libgrass_*)</div><div><br>
</div><div><br></div><div>Any help will be greatly appreciated..</div><div><br></div>-- <br><div><font face="arial, helvetica, sans-serif">Regards,</font></div><font face="arial, helvetica, sans-serif"> Mohammed Rashad K M</font><div>
