There are many coordinate systems. Sometimes it may be necessary to convert between coordinate systems. BlueGIS software can also perform these conversions.

Coordinate Transformation panel can be accessed from the 'Coordinate Transformation' option under the 'Calculations' in the left menu.

Coordinate Conversion

There are 3 main menus in the coordinate transformation panel.

1. Map: Used for displaying the map

2. Point: Coordinate transformation operations are performed on this menu

3. List: Coordinate transformation results are listed here

1. Step: Point Selection

First, select the point in the coordinate transformation panel. There are different methods for selecting the point.

1. Location: The user's location is taken

2. From the map: Point is selected from the map

3. Search: Searching for the place with search panel

4. Typing: Enter Coordinate manually

Point selection is performed by one of these four methods.

Coordinate Conversion

1.1. Location

In this option, the user's location is taken. As a coordinate system, EPSG: 4326 (WGS84) is used.

1.2. From the map

Select the point from the map. As a coordinate system, EPSG: 4326 (WGS84) is used.

1.3. Search

Search the place with the search panel. As a coordinate system, EPSG: 4326 (WGS84) is used.

1.4. Typing

Coordinate is entered manually. Users can determine the coordinate system.

2. Step: Determining the Coordinate System to Convert

After the point selection is made, select which coordinate system the point will be transformed to. There are 3 coordinate systems at the beginning:

  1. EPSG-4326 (WGS 84)

  2. EPSG-4917 (ITRF96)

  3. EPSG-3857

If another coordinate system other than these will be used, it can be easily found from the search panel.

3. Step: Transformation Result

Press the convert button at the end of the panel to complete the coordinate transformation. The result will appear on the screen.

Coordinate Conversion

4. Step: Saving the Point

The converted point can be saved. Press the save button to save.

Coordinate Conversion

After pressing the "Save" button, a panel drop-downs then enter the record name.

Coordinate Conversion

At this stage, the saving process is completed.

5. Step: Viewing Previous Saves

The transformation results saved in the list, which is one of the three main menus in the coordinate transformation, are listed.

Coordinate Conversion

Saves can be deleted with the "Delete" button. To view the point on the map, just click on the coordinates.
