Buffer-data mismatch

jhill1 opened this issue · comments

By choosing a dx that resolves the buffer, we run into the problem that the buffer and original data no longer match (see image). This leads to two problems - where the buffer is larger than the data, we don't
smoothly transition data and where the buffer is smaller we don't have any buffer!

The buffer should be generated exactly as the initial raster and interpolation will have to do the rest. This means if we switch from, say, linear to sigmoidal buffers then the user will have to ensure the distance and/or resolution are ok to do this.
