51 NEW TECHNIQUES IN MAPPING URBAN LAND USE AND MONITORING CHANGE FOR SELECTED U.S. METROPOLITAN AREAS: AN EXPERIMENT EMPLOYING COMPUTER-ASSISTED ANALYSIS OF ERTS-1 MSS DATA Richard Ellefsen San Jose State University 3 California Leonard Gaydos U.S. Geological Survey Philip Swain Purdue University 3 Indiana James R. Wray U.S. Geological Survey ABSTRACT Successful experiments in mapping urban land use, through employment of pattern recognition algorithms in a digital computer by processing multi spec tral scanner data from Earth Resources Technology Satellite-1, have been con ducted by researchers of the Geography Program, U.S. Geological Survey and the Laboratory for Applications of Remote Sensing, Purdue University. Map forms are computer line-printer output and colored prints from a film recorder. Numerous categories of land use and land cover were identified and mapped to make full use of the potential of the computer/scanner system. Several in novations in machine-aided analysis were developed in response to: (1) making rural/urban distinctions; (2) arranging data in map format; (3) aggregating results by statistical units; and (4) solving other peripheral problems. Recitation and critique of the evolved methodology reveals progress made, identifies limitations of the system, and suggests directions for future improvement. RESUME Les Chercheurs du. Programme géographique du Service géologique des Etats- Unis, en collaboration avec le Laboratoire pour l'application de la télédétec tion de l'Université 1 Purdue, viennent de mener avec succès des expériences cartographiques sur 1'utilization du sol urbain. Comme procédé, ils ont utilisé les algorithmes d'indication des patrons, à l'aide d'un ordinateur numérique et en manipulant les données transmises par un lecteur à spectre multiple monté sur "Earth Resources Technology Satellite-1". Les formes de carte ont été le produit de la linotypie raccordée à un ordinateur, aussi bien que des imprimés colorés pourvus par un enregistreur photographique. Elles ont permis d'identifier et de reproduire cartographiquement les dif férentes catégories d'utilisation et de couverture du sol, de sorte ci exploit er au maximum le potentiel du système ordinateur-lecteur. Il a été possible d'apporter plusieurs innovations aux analyses faites à l'aide des machines pour ce qui concerne: 1) la distinction rurale-urbaine; 2) l'assemblage des données sous forme cartographique; 3) le groupement statistique des résultats; et 4) la solution de problèmes périphériques. La présentation et la critique de la méthode développée révèle un avancement aussi bien que les limites de cette technique, et suggère des indications pour un ultérieur perfectionnement.
