Coordinates in iBase
To plot an entity or link on a map, you need to enter coordinate values in two fields that are set up for this purpose. Your GIS package is configured to interpret the values in these fields so that the data can be plotted in the correct location.
In iBase, you will also be able to store geographic data in a number of formats, which are then converted, either manually when you enter the record or automatically after an import or using a bulk conversion. You can also run coordinate queries.
Types of field
- Latitude and Longitude values, entered in decimal degrees
- Easting and Northing data, entered in meters
Converting coordinates to a standard format
When you convert coordinates, they are always converted to decimal degrees of latitude and longitude, using the WGS 1984 datum (a global standard for plotting geographic locations).
To convert coordinates, the entity type requires a Coordinate type field in addition to fields for the latitude and longitude. The Coordinate type field must be directly above the latitude and longitude fields. You enter the coordinates in the Coordinate type field and the coordinates are then automatically converted and displayed in the latitude and longitude field.
