Project Information – fokus-gmbh-leipzig.de

The Project Information of metigo® MAP briefs the user on the project, such as the license and the program release by which the mapping has been created as well as on the number and memory used by individual mapping elements. Note: Especially, if you are working on large mapping projects, the knowledge of the memory used by individual classes is interesting, as it is influencing the run-time of processes. Knowing this, you can reduce the computing power by using suitable symbols and the most suitable tools for your tasks: The selection of appropriate symbols, mapping accuracy and the correct drawing tool when working can accelerate processes and are essential for a successful and efficient mapping. The run-time of individual processes will be reduced. briefs the user on the project, such as the license and the program release by which the mapping has been created as well as on the number and memory used by individual mapping elements. The fields in the upper part of the dialogue inform about the program version, the creation and last modification date of the mapping file, the licence holder as well as the licence type the file was created with. In the upper table below these fields you can trace the history of program release, savings, the licence holder and license types. Here you can if older or younger releases were used to create the mapping. The lower table briefs on the mapping data saved in the project, such as image layers, CAD-drawings, mapping classes, groups and elements as well as detail images and rectifications. The number of items and used memory are given for each type. at the lower left corner of this table, you receive more informations about the individual mapping elements in the mapping classes. So you can estimate if the individual class uses inappropriate symbol definitions using more memory than necessary and can modify them. is a point set by the user, when inserting a vector symbol, any point which is set to construct a spline, an arc or a circle, any point on a polyline. is any vertex as well as any other point created automatically by the software to render the outline of a fill or a hatching. The lower table lists the individual raster elements, such as image symbols and detail shots. These are detail photographs and image symbols. Especially, if you are working on large mapping projects, the knowledge of the memory used by individual classes is interesting, as it is influencing the run-time of processes. Knowing this, you can reduce the computing power by using suitable symbols and the most suitable tools for your tasks: Even if you need to deliver your project with complex and memory intensive hatchings and symbols, you can use for the time of your mapping more simple and therefore less memory intensive symbology. After finishing the mapping you can exchange it with two mouse clicks for all mapping elements within a class at once. In the class Stein_freihand and Stein the outline of two stones were drawn: at the first class with the freehand tool and at the other class with the polygon tool. Though both classes are not equipped with a hatching and a simple continuous line is used as outline. Without receiving more information on the geometry of the mapped object, the lines drawn with the freehand tool need far more memory than those drawn with the polygon line. Many unnecessary vertices have been produced. - If you want to map in freehand mode care to use an appropriate mapping accuracy. This depends on the necessary scale and the size of the elements to be mapped. The resolution of an image pixel in the project (400 dpi Scale 1:50) is between 3 mm on the ground and 0.06 mm in print. These can be calculated using the ). This means a setting of the mapping accuracy for the freehand mode with sub-millimeter precision is absurd, a precision of 2 cm is entirely sufficient, in the print this will be 0.4 mm. Usually vector symbols are less memory intensive than image symbols such as the cross used in this example. At the sample mapping each 16 vector and image symbols were used, the former uses 3 KB memory and latter 7 KB. The selection of appropriate symbols, mapping accuracy and the correct drawing tool when working can accelerate processes and are essential for a successful and efficient mapping. The run-time of individual processes will be reduced. Source.
