Lecture 4 Gis Data Modeling Part 2 Pdf Image Resolution Lecture 4 gis data modeling part 2 free download as pdf file (.pdf), text file (.txt) or read online for free. the document discusses raster data models which represent spatial data through a grid of cells organized into rows and columns, with each cell containing an attribute value. The main detail of this lecture is the characteristics of the raster data structure; its creation; and its types of data storage methods. the conclusion of the lecture gives a comparison of the vector and raster data structure.

Module 4 Lecture Notes 2 Remote Sensing Digital Image Processing Introduction • the raster data model is widely used in applications ranging far beyond geographic information systems (giss). • you are already very familiar with this data model if you have any experience with digital photographs. Key differences are that grid data cells can contain integer or real values, while image pixels only contain positive integer values. the document compares raster and vector data models and their advantages. Chapter 4data models for gis free download as word doc (.doc .docx), pdf file (.pdf), text file (.txt) or read online for free. the document discusses raster data models which represent geographic space as a grid of equally sized pixels. 1) a raster data model uses a grid structure of rows and columns where each cell holds attribute data. linear features are represented by contiguous cells and resolution depends on cell size.

We would say that such an image has a spatial resolution of about 10km and know that anything much less than 10km across is virtually invisible. another strategy for limiting detail is to observe that many properties remain constant over large areas. Many professionals, for whatever reasons, often say they want to get into gis, but what they really mean is that they want a way to display data, not a way to analyze data as can be done with most gis (dent, 1999). Resolution is a key physical characteristic of remote sensing systems. spatial resolution refers to the size of object that can be resolved and the most usual measure is the pixel size. spectral resolution refers to the parts of the electromagnetic spectrum that are measured. Raster data is a method for storage, processing, and display of spatial data. each given area is divided into rows and columns, which form a regular grid.
