Load coordinates from DBF file

Print Top page

This mode is intended for drawing objects on a map from the database table of dBase (*.DBF) format.

The table of a database should contain necessarily fields corresponding to X and Y coordinates.

For execution of loading it is necessary to fill in the information:

1. Name of a map on which the objects will be created.

2. Units of measurements in which coordinates of objects in a database are set (meters,  radians, degrees, national aviation - coordinates are given in degrees in a text kind with the indication of latitude and a longitude (xxzz,s N(S); xxxzz,s E(W))).

3. Name of database table.

4. Creation mode of map objects.

At the included button Objects of one style it is supposed that all records in the table of the data concern to objects of one style which is chosen from the classifier by pressing of button. Further in the Choice of object dialog it is necessary:

- to choose type;

- to choose layer;

- to choose style of object (the example of the image of the chosen object is in Image window);

- to press Ok button.

At the included button Style by key it is supposed that the table contains a field in which unique names of objects from the classifier (keys) are set.

5. Names of fields of the data table containing X, Y coordinates of object.

If the created object should have the characteristic of height (non-obligatory parameter) it is necessary to choose a name of a field in which the height in meters is set (Н coordinate).

6. Name of a field of object number (attribute). The data in this field should be identical for all records which belong to one object, and these records in the table should be located one after another. According to amount of  metrics points, for creation of linear object of such records should be two and more, for polygon - three and more, for vector - two, for point - one. The first such record should contain fields with the filled information on object (key, semantics).

If the name of a field of object number (attribute) is not specified, creation only point's objects is possible.

7. If the object with the title type is created, then the name of a field is indicated, in which the text of the title is set.

8. To establish whether or not the link of created object with record of database table corresponding to it. The established link at the subsequent work with base allows to find by record in the table the object corresponding to it or, on the contrary, by object to find record.

9. To write down or not into the report of transactions. With a view of increase of quick-action at stream creation of objects it is recommended to not write down into the report of transactions.

10. If the created object should have semantic characteristics (non-obligatory parameter) it is necessary:

- press Add button. Into the list of semantic characteristics the record will be added, in which the fields values Semantics name and Field name are unknown;

- choose values of fields: Semantics name and Name of the table field. The name of semantics (Name of a field) gets out of the list which becomes accessible after pressing the left mouse button in the field.

If all parameters are filled correctly, Create button becomes active.
