I meet a problem while I try to calculate the length of a polyline in QGIS in the attribute table.
I created a new column with the function "$length" inside (type: real, 10 digits and 3 digits of precision). My projection is WGS84.
My problem is that the result is completely wrong!!
For example, I used the measurement tool on the desktop and measured a street: I got 525m. On my attribute table I have 0.007...
I tried to change my projection but I still have got the same problem...
Does anyone would have an idea to help me ?
Thanks
