[QGIS-Developer] Switch Layer CRS

[Hauer Lukas]

Hi!

I want to load three layers  into qgis (2.18) via python.
1 Vector Layer (boundary of my farm / fields)
2 Raster Layer ( band4 and band8 from sentinel satellite)
Additionally I want to switch them to the same crs (4326). But if I do this, the field boundaries are not visible as overlay on the raster layers...
I need to zoom out (quite a lot) and my boundaries are somewhere else in qgis.

Some a hint for me?

Here my example code..

import processing
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from qgis.analysis import *

fullPathFeldgrenzen = "Path/to/fields.shp"
fullPathBand4 = "Path/to/Band4/B04.jp2"
fullPathBand8 = "Path/to/Band8/B08.jp2"


fieldBoundary = iface.addVectorLayer(fullPathFeldgrenzen, 'fieldBoundary', 'ogr')
tmp = iface.activeLayer()
crs = tmp.crs()
crs.createFromId(4326)
tmp.setCrs(crs)

band4 = iface.addRasterLayer(fullPathBand4, 'band4')
tmp = iface.activeLayer()
crs = tmp.crs()
crs.createFromId(4326)
tmp.setCrs(crs)

band8 = iface.addRasterLayer(fullPathBand8, 'band8')
tmp = iface.activeLayer()
crs = tmp.crs()
crs.createFromId(4326)
tmp.setCrs(crs)
