We have measured the vertical distribution of HI in the first quadrant of galactic longitude between tangent-point radii, Rt = Ro sin ℓ, of 2.5 kpc and 9.75 kpc at 250 pc intervals of tangent-point distance, using the 305m Arecibo telescope and the 91m and 43m NRAO telescopes. The survey is complete to at least z = ±500 pc and it was sampled with half-beamwidth spacings; the angular resolutions at 21cm wavelength are 4, 11 and 20 arcmin for these instruments.
