Students are confronted to tasks related to cartographic projections, scales, generalization, semiotics and interval definition. Section 2.2. for explanation of constraints). manipulation of many forms of geographic data, and for the cartographic production process to begin a slow migration to digital media. What are the necessary steps in this process and the likely sources of difficulty? (1997). Generalization is an umbrella term for several processes, all intended to remove unnecessary detail. Cartography/Maps (U of Western Ontario) Fundamental of Cartography (NAIS) -- Illustrated and described: Map projections; tables showing properties of projections. Map Projection Overview (Dana/Geographer's Craft) The automatic cartographic generalization is a very complex subject; Information needed to perform a reliable generalization is contained implicitly in the geometric data to be generalized. Lesson 2. Generalization as graphic interpretation of information. Scribd is the world's largest social reading and publishing site. The basic process in map compilation is known as cartographic generalization—the selection and simplification of the material that is to be mapped. cartographic generalization principles define the level of map detainees.

Proceedings, 6th International Conference on Cartography and GIS, 13-17 June 2016, Albena, Bulgaria ISSN: 1314-0604, Eds: Bandrova T., Konecny M. 17 Geographic information system From cartographic point of view the most relevant milestone was the invention of the geographic information system. Algorithms that can extract this implicit information and interpret it in a similar way to an human operator represents the biggest challenge of the automatic Stauffer, A., C. Hanchett, C. Brewer, "Terrain Generalization for Multiscale Mapping" (see item 27-3 above) 24. Hence, cartographic generalization copes with a problem that resembles that of BPMA.

Introduction (3.4MB PDF) PPT 2. Just as word processors allow easy editing of digital text, so cartographers welcomed the ability of digital media to support rapid editing, and to perform the complex numeric operations involved in map projections.

There exist several cartographic generalization models, e.g., [8,24,28]. A theoretical framework for cartographic generalization with the emphasis on the process of symbolization. Generalizing the cartographic base (b) Line simplification - simplify File: World_gen_rob See “Map generalization.ppt” for theoretical details 5. Recent Posts Mapping Sea-Level Rise with Sentinel-6 Visualization in GIS | Introduction. Because maps cannot show everything, the mapmaker must select When mapped at a smaller scale than that of the source map, the amount of map space is greatly reduced and, as a result, map symbols become congested and may even overlap one another. How does national and international legislation on freedom of information and copyright affect the market for geospatial data? –Example: Tourist Maps –Level of measurement (color/symbolization) –Standardization •Dimensionality of representation –Point (0 D), Line (1 D), Area (2 D) – Most maps today are made by “naive map makers”who do not • RuleID Field is the name of the field that will store an integer value for a feature that references a particular representation rule that dictates how it will be symbolized. 8. Cartographic generalization is the process of selecting and representing information of a map in a way that adapts to the scale of the display medium. The cartographer and thematic expert work together to define its content, methods, symbology, etc. Cartographic data and information: geodesy, remote sensing, GPS, data bases. Lesson 2: Visualization in GIS. Generalization zGeneralization is considered a necessary part of cartographic representation. Webex Presentation to USGS National Map Product and Service Leads by C.

Cartographic generalization is the process of selecting and representing information of a map in a way that adapts to the scale of the display medium. may not be strictly observed because the working map is only for the author, not for the end users. Scale, coverage and format. Man-made: urban development, new roads. zChange of scale is often the reason that calls for generalization.
