Hi All,
I'm using Ogr2Ogr to convert kml file to shapefile but the color of the
shape output file is unique, i 'm always loosing the colors of my polygons
in the shapefile...
is there any way to solve this problem ?
Best regards;

Hi
There is no graphical representation in the shapefile.

Wael,
There is no support for style information in shapefile format. However, you
can store the style info as a regular attribute value. Using OGR's SQL you
can extract the style string from the kml data and then store it in the
shapefile. Please go through the OGR SQL page[1]. You can get the
Wael,
First, make sure you are using the libkml driver and not the kml driver.
The libkml driver can read the style information. Then you can get that
information in your shapefile by specifically requesting the ogr_style
column.
Try adding
-sql 'select *, ogr_style as style from Layer0'

Hi all,
I'm investigating gdal_polygonize.py
I'm thinking of using it to convert a DEM-file to a polygon shapefile.
I did a quick test using gdal_polygonize.py logan.tif -f ESRI Shapefile
logan_poly.shp and got a shapefile.
But this shapefile is huge, it created a polygon for every pixel value.
Hi guys!
I'm trying to create a shapefile containing a single polygon, but
unfortunately I'm facing an error that I have no clue how to solve.
I'm successfuly creating a datasource and a layer with:
OGRLayer* testLayer = newDataSource-CreateLayer(test,NULL, wkbPolygon,
NULL);
Then when I try to

Land cover classification rasters can have large areas of the same

Ok, I've discovered that myPolygon has geometryType *wkbGeometryCollection.*
When I try to:
newDataSource-CreateLayer(test,NULL, *wkbGeometryCollection*, NULL);
it fails and returns NULL.
So my question now is: How do I create a wkbGeometryCollection layer (if
possible) or how do I correctly
For anyone else having the same problem like mine,
I solved my issue just iterating over the wkbGeometryCollection, gathering
all polygons in it and creating a feature for the my layer for each of them.
