Raster model - Study guides, Class notes & Summaries

Dot map Correct Answer--Uses uniform point symbols to show partial data, with each symbol representing a unit value -Create a visual impression of density by placing a dot or some other symbol in the approximate location of the variable being mapped. Are most larger scale print maps 2D or 3D? Correct Answer-2D TIN (Triangulated Irregular Network) Correct Answer-a vector terrain model that allows for non-equally spaced elevation points to be used in the creation of the surface ArcGIS su...

Geodatabase object oriented spatial model, native data structure for ArcGIS, and is the primary data format used for storing, editing, and managing geographic data. Types of Geodatabases Personal, File, Enterprise, workgroup Types of Geodatabase datasets Geometric network, network dataset, parcel fabric, terrain dataset, LAS dataset Distance relations specifies how far is the object away from the reference object. Examples of distance relations at, nearby, in the vicinity;far away Euclidean...

GISP Verified Solutions Data Models - Data Exploration: A data-centered query and analysis process to explore and understand data. - Dynamic Segmentations: A data model that employs linearly measured data on a coordinate system for analysis. - Georelational Data Model: A vector data model that uses a split system to store geometries and their attributes separately. - GeoSpatial Data: Data describing both the locations and characteristics of spatial features on the Earth's surface. - Obj...

Spatial data  All of the information that can be tied to a specific locations. Data with a geographic location, representation, or reference point that it describes. Visually represented as layers which allow the user to select different sets of data to display the main viewing window in a stacking manner. Cartography  The science of mapmaking, including data inclusion, layout, elements, colors, and design. Shapefile  A vector data storage format for storing the location, sha...

GIS Questions and Answers Already Passed What is GIS A system with spatially referenced data with meaning behind the data using explicit links. What questions are unique to geography and therefore GIS? questions related to trends, location, conditions etc Why is GIS called an "enabling technology"? because you can use it with several different disciplines. What industry is the biggest spender on GIS and why? Utility companies because they need their databases current and up to date. What i...

UNIT -1 INTRODUCTION TO COMPUTER GRAPHICS chapter 1-10 COMPLETE STUDY GUIDE WITH END OF CHAPTER TEST BANK 1.1 DEFINITION OF COMPUTER GRAPHICS Computer Graphics is principally concerned with the generation of images, with wide ranging applications from entertainment to scientific visualisation. In other words, we can say that computer graphics is a rendering tool for the generation and manipulation of images. Thus, by using a computer as a rendering tool for the generation and manipulation of i...
