[Qgis-user] Georeferencing Raster

[Patrick Dunford]

When you are replying to a digest, kindly observe standard netiquette

discussion.

Any activity that involves processing raster images is by definition 
much more resource intensive than editing vector layers. When you are 
drawing maps, most of the layers you are likely to be working with are 
vectors. It is inevitable your system will be much more impacted in 
performance when processing the raster data than it is for drawing 
vector layers. The onus is basically on you to ensure you are using a 
computer system that has good performance specifications.

> my collegue got some trouble with georeferencing raster images. As soon as he activates the tool  ?LAYER >> GEOREFERENCING? his system gets very, very sloooow. It takes plenty of time even to open the raster image and then to set referencing points. While changing the windows between Map and Referencing Tool the windows are getting grey and show ?No response?. In the end he doesn?t know wheter the system is still running or ?died? along the way.
