Enhanced geocoding

Print Previous page Top page Next page

Enhanced geocoding mode is intended for plotting objects from the database table of the format dBase (*.DBF) or Paradox (*.DB).

The database table should contain fields appropriate to X and Y coordinates.

For execution of the given mode it is necessary to fill in the following information:

1. The units of measurement, in which coordinates of the object in the database are preset (meters, radians, degrees, national aviation - the coordinates are given in degrees as text with the indicating of a latitude and longitude (xxzz, s n (s); xxxzz, s e (w)), WGS84(degrees)).

2. Name of an open map, on which one the objects will be built.

3. The mode of map objects creation, for this purpose you must actuate one of bookmarks: Single-type objects, Type from key, Type from user code.

- Single-type objects bookmark. It is supposed, that all records in the data table belong to single-type objects which one (type) is selected from the classifier by pressing of the button . In the Map object selection dialogue it is necessary:

- to select localization;

- to select a layer;

- to select the object's name (you can see the image example of the selected object in the Image window);

- to press Ok button.

- Type from key bookmark. It is supposed, that the table contains a field in which one the unique names of objects from the classifier (keys) are preset.

- Type from user code bookmark. It is supposed, that the table contains a field in which one the user's codes in character or numerical view are preset. Each such code means one type of a map object. Mode setting:

- to select a field in which one the value of a user code is contained. The list of all unique codes which are contained in the data table will be automatically formed.

- to set the correspondence of a user's code and name of the object from the classifier. For this purpose the mouse cursor is placed on demanded record in a field  "Object name from classifier". After left mouse button click the dialogue "Map object selection" opens where one object type is selected. The object name from the classifier registers in a selected field. If the correspondence of a user's code and the object name from the classifier is not set the objects with the selected code will not be created.

4. Fields names of the data table having X, Y object coordinates, if the created object should have the height characteristic (optional parameter), it is necessary select a field name in which the height in meters is preset (H coordinate).    

   5. Field name of object number (sign). The data in it field should be identical for all records which one belong to one                                                          object, and these a records in the table should be allocated one after another. According to amount of the metrics points for               creation of the linear object there should be two and more such records, for area object - three and more, for vector - two, for dot - one. The first such record should contain fields with the filled information about the object (key or user number, semantics). If the field name of object number (sign) is not indicated, only the creation of point objects is possible.  

6. If an object of a type the title is created, the name of a field is indicated in which one the text of the title is preset.

7. To set or not to set the link of the created object with appropriate to its record of the database table. The installed link at the subsequent operation with the base allows to find by a records in the table the appropriate to its object, or, to the contrary, by the object to find a record.

8. To save or not to save into transaction log. With the purposes of speed increase at stream creation of point objects it is recommended to not save into the transaction log.

9. If the created object should have the semantic characteristics (optional parameter), it is necessary:

- press Add button. Into the list of semantic characteristics the record will be added in which value of fields Semantics name and Field name will be "unknown".

- select values of fields Semantics name and Field name. Semantics name (Field name) is selected from the list, which becomes accessible after left mouse button click in the given field.

10. If the list of semantic characteristics contains semantics having the type Code from the classifier, it is necessary to indicate in what sort the information is kept (or code, or in the decoded character sort).

If all parameters are filled correctly Ok button will be actuated. By pressing of this button we create objects with selected parameters.

All parameters are saved in INI - file of a map. At repeated activation of the form, when a name of an open map, name of the database table and its structure have remained the previous, settings are restored automatically.

At termination by Cancel button the settings are not saved, by button the settings are saved from the previous session.
