I have a polygon shapefile (Vesijärvi lake). The lake has many islands, bays and inlets. When I look at the attribute table, there are actually two adjacent features: Northern lake and southern lake.
I have a pre-defined rectangular area of interest with the min x, max x, min y, max y in ETRS-TM35 FIN projected coordinates. The area of interest overlaps with the both parts of the lake.
I also have a pre-defined raster cell size (10 meters)
My task is: Create a .tif raster file, where 'water' cells (inside the lake) have a value of 1 and 'non-water' cells (outside of lake) have a value of 'no data'.
I know that in ArcGIS you can use a 'Feature to Raster' tool, but I don't have ArcGIS. I'm trying to use an open-source GIS, preferably QGIS. In QGIS, I found a tool called 'Rasterize' but I cannot set the minimum x, maximum x, minimum y, maximum y, cellsize and the lake polygon mask. There is a 'Horizontal' and 'Vertical' expression but any combination of numbers gives me an expression is not correct error.
Any help with using the QGIS rasterize tool (or a similar free vector-to-raster tool) for converting a polygon shapefile to a raster with the predefined extent, cellsize and mask would be appreciated.
