It turned out the resolution of my region was set to 1 - presumably that's in degrees, so that wasn't enough. Moved it down to 0.001 or so and getting better results. Thanks everyone.<br><br><div class="gmail_quote">

Hello, I've imported a vector of points into GRASS - it's approximately a grid with ~24k points according to GRASS. I'm trying to interpolate it, but what ever methods I try (v.surf.idw or v.surf.bspline), the resulting raster is just one point, approximately in the middle of the grid with the average value of the z values. <br>
I am able to see the points rendered as a vector field, so the data looks like it's been imported correctly, but I can't figure out this interpolation step.<br>Thanks!<br><br><br>
