Digital map compilation by Mapinfo geographic information system.
Compilation of digital map by Mapinfo CIS program is made by two ways:
1.Mapping by researching automatically of cosmic photos in artificial satellite and surface center without participation of researchers.
2. Vectorization of its objects after giving the topographic map pre-compiled by researcher to the memory of computer by scanner and creation of thematical maps after creation of electron basis of numeral information.
First method is nowadays used in great state significant organizations and because that, their information basis and apparatus provision is confidential for students and it is impossible to use them, we just give common information on them in this methodic case.
During compilation of digital map by second way, because Mapinfo CIS program apparatus provision and their usage is not confidential for students, sequence of creation of digital map by it and Surfer program is expressed here.
During creation of digital map in Mapinfo and other CIS programs, firstly geographic coordinates of described area is determined and then cartographic projection of drawn map is assigned. Most of topographic maps compiled for Azerbaijan area have been created by Pulkovo 1942 coordinate system. And after drawing of needed thematical map, that map should be overturned to new coordinate system applied in our Republic.
Because, now map or profile descriptions are created by Global Position System in all spheres of economy.
Compilation of digital maps by Mapinfo Cis program is given with following sequence:
As we noted, after selection of coordinate system and cartographic projection of drawn map, for screening of memorized map by Mapinfo CIS program, Mapinfo program is installed.
After installation, File-Open table-file types-Raster image orders are executed, necessary map is indicated, then open-display.
If selected map is not screened, then enter Lauer Control in Map menu of Mapinfo and after clicking label button, you should remove click sign in front of display word in new window and then press ok.
After this operation, map will be seen.(Pic.1)
After screening of vectorized map, for activation of Mapinfo orders signs, click sign is put in second column in front of Cosmetic layer in Layer Control part of Map menu and press ok.
In this case, signs in Draw menu will be activated (that is, those will have special color).
After that operation, linear, areal and pointed objects on map are digitized by order signs appropriate with their vectorization. For example, after drawing region contours in administrative regions map of Azerbaijan Republic, Save cosmetic object order in Map menu is executed and it is called as regions.(Pic.2)
After drawing of all regions, map category named regions in Layer control part will be seen in Map menu. Main map description named Pol in 3rd row, after removing click in front of its category, only region contours will be seen in screen.
In next level, maintenance and Table structure orders in Table menu of Mapinfo is executed in purpose of making basis for description of titles of regions, social-economic and physical-geographic indicators.
Here, in opened window, Add field button is clicked for sometimes. Then, Field 1, Field 2, Field 3… etc parts are emerged in screen.
Field 2 part is indicated-names word is written in front of name word by changing of Field 2. Integer word by being changed in front of Type word, is substituted by Character word. Width word, by being changed of forward number, number of maximum letters of given names is indicated.
Then Field 3 is selected- Population word is written in front of Name word. Integer word is kept in front of Type word.
By this order, other field words are substituted by information belonging to residence points.
Information expressed by fraction numbers is taken as decimal. Here, number of complete and fractional numbers is indicated. Number in fraction is indicated in near of decimal word.
For adding of information concerning region-city and village, Enter table-maintenance-table structure part, click ok in front of words of created schedule.
For adding of information, New browser window order is executed in window menu.
In this case, following window will be seen in screen. For writing names, Azerbaijan alphabet is indicated by selection of order Text style in Option menu. Then, object names and number information concerning them are written to schedule.
After completion of schedule in following form, it is memorized by Save table order in File menu of Mapinfo.
For describing names in created basis in screen, click is put to last square in front of each object title in Layer Control Part of Map menu and press ok. In this case, names of objects will be seen in screen.
If object names are described by other alphabet in screen, then Label order in Layer control part of Map menu is executed.
Then, Aa button is pressed in Styles part and Azeri or other alphabet is selected.
Then, region names will be seen with Azerbaijan or other alphabet.
Create Thematic Map order in Map menu should be executed by using from electronic map model made for compilation of thematic maps.
In this case, words and symbols on traditional map compilation methods will be seen in created window.First of these methods is used for grouping of areal objects on the basis of each one colored scale or draft scale. For example, after selection of color scale, information schedule on regions is screened. Firstly, one of its schedule columns is selected. For example after indication of population column and that word, following window is screened in next level. Here, Ranges order is selected and length of interval number is selected in created window and press ok. After selection of Equal count method considering number and length indicators of selected interval, Recalculate order is executed. Interval indicators show other number and percentage in new window. Then, it is necessary to consider that, distribution of percentages on all intervals should reflect information of thematic map.
So, we see distribution of percentage or number obtained in last calculation on all intervals.If you want to change description of numbers calculated on created intervals by color way, then Styles order is executed and make changes.Head and subtitles of map legend to be drawn in this regime is executed by Legend order.In last level, ok is pressed and population map is described in following form by color scale. Compilation of thematic maps with diagram method by being different, is consist of following levels. 1. Method selection level.
After selection of diagram method, one or some column information should be turned to the right side of window by add button seen in screen. Then, diagram on selected columns will be seen. In this window, Styles order is executed for changing of diagram elements in right side. After execution of styles order, color (brush), (width), height and description form (Stacked, Multiple Bar, Independent Scales) of diagram may be changed.
After compilation of selection operation, diagram will be as follows.
After compilation of all requirement and legend form for description of diagram, ok is pressed and following sex content map of population is screened.(Pic.3)
Styles order is executed for color of district sectors (brush), diameter, complete or partial view (Half pies) and measure difference (Graduater). (Pic.4)
Then, options order is executed for assignment of position of diagram in map in this regime.
9 black points seen in right side in selected option regime indicate position of diagram in respect of contour center. (Pic.5)
At last, following population map is seen after execution of ok.
If click is removed in front of Half Pies order, population map will be seen in following form as sectored districts.
During description of population or other indicators on regions, draft method is also used. For example, distribution of population on regions may be given by draft method with following form.(Pic.6)
As indicated, some social indicators may be described in map by being large or small. For example, number of cinemas may be described in following form.(Pic.7)
