QGIS 2.0 Working with tiff raster file. Reprojections are in WGS84 Mercator.
Here is my problem: I am trying to use buffers or urban areas to analyze light intensity on a raster layer. I want 30 miles, 60 miles, and 100 miles for the buffer sizes. I have reprojected the vector layers to WGS84 / World Mercator. When I ran a zonal statistics, everything went smoothly until I was double-checking the output. I saw "null" on a few of the rows of information in the data table. When I looked at the raster image, which I also reprojected to WGS84 / World Mercator, a large chunk of the raster layer was missing. Images below.
Non-reprojected raster layer:
Reprojected raster layer:
I am assuming there is a problem with my reprojections. I am still new at GIS, so please bear with me. Thanks in advance.
