We present the Bolocam Galactic Plane Survey (BGPS), a 1.1 mm continuumsurvey at 33" effective resolution of 170 square degrees of the Galactic Planevisible from the northern hemisphere. The survey is contiguous over the range-10.5 < l < 90.5, |b| < 0.5 and encompasses 133 square degrees, including someextended regions |b| < 1.5. In addition to the contiguous region, four targetedregions in the outer Galaxy were observed: IC1396, a region towards the PerseusArm, W3/4/5, and Gem OB1. The BGPS has detected approximately 8400 clumps overthe entire area to a limiting non-uniform 1-sigma noise level in the range 11to 53 mJy/beam in the inner Galaxy. The BGPS source catalog is presented in acompanion paper (Rosolowsky et al. 2010). This paper details the surveyobservations and data reduction methods for the images. We discuss in detailthe determination of astrometric and flux density calibration uncertainties andcompare our results to the literature. Data processing algorithms that separateastronomical signals from time-variable atmospheric fluctuations in the datatime-stream are presented. These algorithms reproduce the structure of theastronomical sky over a limited range of angular scales and produce artifactsin the vicinity of bright sources. Based on simulations, we find that extendedemission on scales larger than about 5.9' is nearly completely attenuated (>90%) and the linear scale at which the attenuation reaches 50% is 3.8'.Comparison with other millimeter-wave data sets implies a possible systematicoffset in flux calibration, for which no cause has been discovered. Thispresentation serves as a companion and guide to the public data release throughNASA's Infrared Processing and Analysis Center (IPAC) Infrared Science Archive(IRSA). New data releases will be provided through IPAC IRSA with any futureimprovements in the reduction.
