Calculation of entry the objects

Dialog carries out overlay operation of multiple overlay of objects of two lists by a crossing method. Objects of source classes are defined by two lists: list 1 - objects of overlay and list 2 - analyzed objects. Lists of objects of source classes must be prepared in advance by means of the mode "Lists of objects".

Result of the mode operation are the calculated values of the areas of objects entry of the list 2 (analyzed objects) onto objects of the list 1 (objects of overlay). The program determines the multiple entries of objects of list 2 into input objects of the list 1 and calculates the area of each entry in absolute units, and as a percentage of the object of overlay.

To start calculations, you must select the lists of objects in the drop-down menus and click the "Calculate" button. Different lists should be selected. Results of calculation of multiple overlay will be shown in the table. As the identification information, displayed in fields of the table “Object from the List 1” and “Object from the List 2”, there is used the semantics chosen in drop-down lists “Semantics 1” and “Semantics 2”. These lists are formed from the list of semantics of the first object of the corresponding list (the first object of the map that has the minimum number in the list of maps). If the semantics "Name" (code 9) is not found in the list of semantics, it is forcibly written into the end of the list. In the fields of the table with the name "Square", the areas of objects from the list 1 and list 2, respectively, are entered. In the  "Total square" field there is recorded the area of crossing the object of the list 1 with the object of the list 2. In the field of the table "% entry" there is written in percentage, which part of the object of list 2 is included into the object of list 1.

The formula used in the calculation is such:

In the field of the table the "% overlay” there is written in percentage, which part of the object of list 1 is imposed onto object of the list 2. The formula used at calculation is such:

For unloading data into a CSV file, click the "Report" button. In the dialog, you can select the type of separator that will be used when unloading data.

Also, after performing the calculation, it is possible to write into the objects of list 1 and of list 2 the data about what objects from the other list enter the object, and also the area of ​​entry and the percentages of entry and overlay. For this purpose it is necessary to choose at first in objects of what lists it is necessary to fill semantics, by specifying the tags “Fill in the semantics of the objects in the list 1” and ” Fill in the semantics of the objects in the list 2”. If after the last calculation the status of these flags has been changed, then you need to perform the calculation once again. After this, by pressing the “On the map” button, semantics filling is made. The map must be created using the agro10t.rsc classifier. Into semantics “Entry in field” (code 637) of object there is recorded the semantics contents “Name” of object from another list. Into semantics “Percentage of entry in the field” (the code 638) there is recorded the area's part of object of the list 2 included into object of the list 1 in percentage. Into semantics "Percentage of overlay the field" (code 640), there is recorded the area's part of ​​object of list 1 imposed on the object of list 2 in percentage. Into semantics "Area of ​​entry in the field, ha" (code 639), the area of ​​object of list 2, included in the object of list 1, is recorded in hectares. If one of the check-boxes was not selected, the previously filled semantics of list objects with codes 637-640 will be cleared.

Tag “Clarify area” carries out information function and is not available for change, it duplicates the value of the tag “Precise square and length” from the "Options" section of the main menu of the program.
