RASTER AND VECTOR DATA INTEGRATION, INTERACTIVE EDIT, AND ANALYSIS

SPATIAL INFORMATION SCIENCES, INC. PROPOSES TO CONDUCT A RESEARCH PROJECT LEADING TO THE ESTABLISHMENT OF A CAPABILITY TO COMBINE RASTER AND VECTOR DATA STRUCTURES INTO A UNIFIED DATA SET. THIS UNIFICATION OF DATA STRUCTURES WILL ALLOW FOR THE SIMULTANEOUS, INTERACTIVE EDIT OF THE COMBINED STRUCTURES TO INCLUDE GEOGRAPHICAL POSITION EDITS AND DATA VALUE MODIFICATIONS, AND THE RESTRUCTURING OF RASTER DATA SETS INTO TOPOLOGICAL STRUCTURES. IN COMPLETING THIS PROJECT, SIS WILL TEST AND EVALUATE THE EFFICIENCY OF AUTOMATIC VECTOR DIGITIZING TECHNOLOGY FOR THE CONVERSION OF NON-IMAGED SPATIAL INFORMATION. SPATIAL DATA, BOTH IMAGED AND NON-IMAGED, ARE CRITICAL TO THE EFFECTIVE UTILIZATION OF THE NEWLY DEVELOPING GEOGRAPHIC INFORMATION SYSTEMS (GIS) IN RESOURCE MANAGEMENT. CURRENTLY, IMAGED AND NON-IMAGED SPATIAL DATA FILES CANNOT BE INTEGRATED INTO A SINGLE DIGITAL DATA BASE FOR ANALYTICAL PURPOSES. ONCE OPERATIONAL, THIS NEW TECHNOLOGY WILL ENHANCE THE VALUE OF NASA'S SATELLITE AND REMOTELY SENSED DATA FOR USE WITH GIS TECHNOLOGY.
