An urban radiation obstruction model

An urban street canyon radiation obstruction model was developed. The model can describe community structure in terms of the type and dimensions of every building, block, road, park, etc. The need for massive data acquisition in regard to obstruction modelling calls for computerized algorithms, relieving the researcher of the needless tedium of hand calculations and the accompanying high degree of error and labor costs. The model program OBSTRUCT was written in Fortran IV for use on the IBM 3033. To facilitate changes or modifications, OBSTRUCT was written in modular form.
