VS: [UMN_MAPSERVER-USERS] Extent of several (500+) TIFF images

[Rahkonen Jukka]

Hi,
 
Use "ogrinfo" utility in order to get the extents of your shapefile holding the tileindex. Usage is like this:
 
ogrinfo tileindex.shp tileindex -summary
 
The response will include an Extent -line, which can be copied and pasted to your mapfile, just remove extra parenthesis and commas.
 
Regards,

Aihe: [UMN_MAPSERVER-USERS] Extent of several (500+) TIFF images


I'm using a layer of more than 500 tiff files containing DEM information of a great area. I have created a tile index of all these maps using the gdaltindex program to use as a layer in my mapfile. It generated a .shp file along with a .dbf as expected. 

I'm having problems to find the proper EXTENT to my map file that will for the moment only use the layer described above. Is there any easy way to get full extent of these images or shapefile? The utility program gdalinfo gives me proper information to build the extent of a single raster file, but I'm not aware of a tool that gives this kind of information of a shape file. 

I've tried to use OpenJUMP [http://openjump.org] to hover the mouse over the min and max points of the shapefile but I had no success using the coordinates it gave me.

Any suggestions?
