[gdal-dev] ogr2ogr .SHP to .KML conversion problem

[Mattias Carlsson]

OK, so I got the conversion working, probably a newbie mistake, as the solution was mainly to switch datum, i.e. change the command from

ogr2ogr "KML" LINE.kml LINE.shp

to




	
	
	
	

ogr2ogr
-s_srs EPSG:27700 -t_srs WGS84 -f "KML" LINE.kml LINE.shp

However, before realising that, I managed to compile and install gdal 1.7. Using gdal 1.7 did not crash reading the file using the initial command line but gave a warning about coordinates exceeding limits, and from this I eventually realised my error! Thus, I am not sure whether gdal 1.5 would still work using the correct conversion (probably).

The next problem is to display the kml file on a map; there are about 500 polylines ranging from a few to hundreds of points each. Sending this to google maps (by using "My Maps"->"Import") displays the data over several tabs, which is undesirable. Any ideas on how to display all the data simultaneously?

Thanks,

Mattias

Use gdal_translate --version
Since you told me that you are using GDAL version 1.5.0 from December 2007, I suggest that you upgrade to GDAL 1.7.0 from January 2010. Greg

I am trying to learn how to use ogr2ogr to convert a shapefile to kml, but fail to do so and cannot understand whether I am at all on the right track or completely lost (very much beginner in GIS). I would like to convert either, or all, of the files on <http://www.nationalgrid.com/uk/LandandDevelopment/DDC/GasElectricNW/undergroundcables/shape/> to .kml and try using

>ogr2ogr -f "KML" LINE.kml LINE.shp

but get a buffer overflow (I can send a backtrace if this would help):

>*** buffer overflow detected ***: ogr2ogr terminated

(btw, I am using Ubuntu 9.10)

Apologies if this is the wrong forum or totally basic, but after many frustrations I am getting desperate and, please, please, guide me in the right direction...

Thanks!
