Trang 11+ A: a general introduction, the title of the Web Atlas
+ B: is the list of maps in Web Atlas
+ C: The map displays pages
+ D: shows the information for the maps
+ E: To view links or return to the map pages
2.1.1.3 Principles of map design multi-scale
The design criteria for multi-scale maps in the Web Atlas include:
+ Zoom ratio ability of the design technology
+ Map window size in interface
+ Area and scale of input data
However, it is needed to ensure 3 types of scale:
+ Minimum scale should display the territorial area in the framework for the size of the map
+ Maximum scale is equal to largest scale the original map for displaying detailed information of the map
+ The average scale between the two types of zoom levels
2.1.1.4 Designing multimedia components
The technical design of multimedia components include works such as collecting, processing and analyzing data and creation of multimedia components database
2.1.1.5 Content design
In addition to the content elements are designed as the requirements for traditional Atlas: design projection and coordinates, the elemental geographic base, main content, secondary as well as other supporting content, when design contents of Web Atlas need
to build a database of information for the object attribute maps for finding and analyzing information on the GIS platform later
Trang 122.1.1.6 The methods of maps content presentation
Normally in cartography people usually use 10methods for showing the content of thematic maps However, not every map that also applies all methods, so before using these methods to denote map content needs to study the characteristics of each object and methods to use that rationally
2.1.1.7 Map symbols
Indeed, the map symbols as a means to express the content of the map In the web map, symbols can be used with some different than paper maps For example, the symbols can be connected to the hidden information inside by the combination of maps with information in a geographic information system, or symbols can change the shape, size when clicked on,
2.1.1.8 Colors used on web map
A Colors on the Web map
The color on the web map depends primarily on the designer All maps are designed under the influence of color in the view of the cartographer, this leads to the subjective requirements for color recognition However, our computers display colors depending on the configuration of the machine (16 bit, 24 bit, 32 bit, ) so web map designers always need to based on the structure the popularity
of computers to design color map
B The role of color on the map
Use color to increase the amount of information-rich maps and its contents Colors make beautiful maps and more artistic
C The color model in establishing, printing maps in computers There are many color models in practice, such as RGB, HLS color system, CMY color system,
