Hi ,
My user asked me to give him some description of the algorithm of gdal
contour generator as detailed as possible. I have poor theory about this
problem, anyone could tell me some workflow of this module to save time when i
browse the source code? Thanks.
Hi,
I want to generate contours with different intervals in sevaral elevation
ranges. For example, if the elevation range is (0,100), the contour interval is
10; if the range is [100, 500), the interval is 50; and if the range is [500,
2000), the interval is 200. Can all those contour genera
Hi, When i call OGRLayer::CreateField() to create a field with a Chinese
name[UNICODE], i got errors. The driver is ESRI shape. Does
OGRLayer::CreateField() suport UNICODE in ver1.4.1 ?

Hi,
When i tried to update my whole program from ver1.4.1 to 1.5.2, all worked
well except the OGRFeatureStyle module. The function OGRStyleMgr::AddStyle()
couldn't write the provided style name and style string right with ver1.5.2,
but could run smoothly with version 1.4.1.
My code :

Hi,
i try to delete features from a set of shape file, sometimes get error. I
use this version of ogrshapelayer.cpp :
http://trac.osgeo.org/gdal/changeset/10969 . Delete feature in two ways would
get different result:
(1) for(iFeat=0;iFeatDeleteFeature(0);
if(cplE==CE_None)

Hi,
To update shape files. i got two questions:
1. How could i delete a field from a shapelayer?
2. How to set a value to a specified field of all records? Could i use SQL
sentences like "set field_name='value'" on the datasource of shapelayer?
Thank you.
