Presentation Transcript

    1. Digital Spatial Data Francisco Olivera, Ph.D., P.E. Department of Civil Engineering Texas A&M University

    2. Definitions Digital Spatial Datasets: Synthesis -- in electronic format -- of geographic (map) and tabular (table) information. Data structure: method used to organize and store digital spatial datasets.

    3. Data Types Features Point datasets Line datasets Polygon datasets Surfaces Grid datasets TIN datasets Images datasets Networks Simple dentritic networks Simple loop networks

    4. Features All points required to define the feature geometry have to be stored as part of the feature definition.
