Raster data model - Study guides, Class notes & Summaries

What is the fundamental problem with representing geographic data?  The world is infinitely complex, so any digital representation of geographic phenomena is inherently incomplete. Name the six types of spatial analysis.  Six types of spatial analysis are queries and reasoning, measurements, transformations, descriptive summaries, optimization, and hypothesis testing. Describe uncertainty associated with the raster data model.  In the raster data model, spatial objects are defi...

GIS Exam #2 Questions & Answers 2024 Data Model - ANSWER-Data models are a set of rules and/or constructs used to describe and represent aspects of the real world in a computer. Two primary data models are available to complete this task: raster data models and vector data models. Spatial Data - ANSWER-Spatial data is usually stored as coordinates and topology, and is data that can be mapped. Spatial data is often accessed, manipulated or analyzed through Geographic Information Systems ...
