[Qgis-user] Hi everybody

[Gerardo Jimenez]

Sorry,
 if you want all your layers in the same crs you have to reproject your data. This is easy, load a layer, select it and choose save as, there you have to define a new name and the crs of your choice. One thing, in order that the reprojection could succeed  both the project and the layer must have the same crs (see my previous post)

If you have a shape file it should have also a *.prj file. This file defines the projection of your layer. By default, Qgis assumes that your data is a lat lon wgs84 and coordinate units degrees. If you have your *.prj file try this first
Open QGis, load the layer select it and choose set project crs from layer
If that does not do the trick try opening the prj file in a text editor and try to identify your CRS (Coordinate Reference System). Then, in Qgis, after loading your layer, Go to layer properties/General choose the specify button and look for your crs in the "Projected Coordinate Systems" section. Do the same at Settings/Project Properties/CRS Tab.
Hope it helps

Hi, I'm Giacomo Fontanellin from Florence, Italy.I'm a PhD for University of Basilicata, I work on remote sensing of environment.I'm quite new with QGis, buti I like it, cause it's very easy to use and user-friendly. This is my problem: I've got many shape file in a project, each of those with different projections, but I still can visualize the polygons in the right position. The spatial extension of the files is almost the same and is defined in meters: example: xMin, yMin 1714882.75,4845790.12 : xMax,yMax 1735233.69,4861856.86.

Unfortunally I've got a layer with the spatial extension defined in degrees: xMin, yMin 10.94,43.7388 : xMax,yMax 11.7543,43.9773, and I can't visualize it in the correct location. How can I change the extension of the files from degrees to meters and viceversa? Thank you very much and sorry for my english
