Using geographic coordinates
You can use geographic coordinates (latitude, longitude) to indicate the position of the point data in your text file. For importing generic text files, Google Earth supports coordinates described in
- Degrees, minutes, seconds (DMS)
- Decimal degrees (DDD)
- Degrees, minutes, with decimal seconds (DMM)
Refer to Entering Advanced Coordinates for a detailed description of the latitude/longitude coordinates supported in Google Earth as well as the type of syntax supported.
You can use any number of fields in your custom data file to label and describe the points and display them the Google Earth application. Optional fields can be defined as the following values:
- Text or strings - A string field can contain both numbers and alphabetic characters. What actually defines a string with respect to style templates is that the string itself is either enclosed in quotation marks, or contains white space so that it cannot be interpreted as a number. This is an important distinction to keep in mind when using style templates applied to fields.
- Floating point value
With style templates, you can take advantage of these field types to create useful visual effects in the 3D viewer such as graphs or color-coding of data based on the values in the fields.
