To display spatial information in Maps, details must be entered in the Level Properties tab of a specific Level 3. This spatial information can be linked to GIS software for use in mapping and spatial analysis. More than one projection can be saved, however only one should be selected for viewing in DataSight Maps.
Add a Projection
-
Select the Level Properties tab in the Main Panel. You can also right-click on a level 3 site and select Properties.
-
To add a projection, after focusing your mouse on the Projections grid view, click New in the Quick Access Toolbar. A new row will be added to the Projection grid view.
-
Navigate to the text boxes under Projection for entry of Longitude and Latitude. In DataSight all coordinates are displayed in decimal degrees.
- If your coordinates are given in decimalised fractions, click within the respective text box and type the value.
If your coordinates are given in degrees, minutes and seconds, click in the text box and then click on the
button to access a pop-up window.

Enter your Latitude Degrees, Minutes and Seconds and select the North or West Radio Button. Click OK.

(Optional) Enter your altitude value in the Altitude text box. No specific units of measurement are required at present, and the entry of this data is to ensure that all spatial elements are stored together for use.
-
Enter the unique Projection Information to clearly identify the projection relevant to these coordinates. This mandatory column is required to be able to identify unique projection rows when data is exported to a third party software.
-
You can choose which of your projections will be used to display the locality of your Level 3 site in OpenStreetMaps. Click the Display in Map checkbox for the chosen projection.
-
Click Save in the Quick Access Toolbar at any point to save changes and continue, otherwise when you Close the Level Properties window you will be prompted to save your changes.
Note

In order to display projections on a Map, the latitude and longitude values must be valid. The valid range of latitude in degrees is -90 and +90 for the southern and northern hemisphere respectively. Longitude is in the range -180 and +180 specifying coordinates west and east of the Prime Meridian, respectively.
