AspEdit manual Coordinate conventions
Geodetic datumAspEdit is not taking the geodetic datum into account in any way, it performs no conversions. The coordinates in the exported OpenAir files will be the same as the ones given in the input. It is the users responsibility to make sure the correct geodetic datum is used.
UnitsThe default units are set in the List. When an area is created, it will use these units. From then on, the units for that area are not dependent upon the setting in the list, they can only be set from the Area dialog box. Different units can be set for all areas.
Following units are available:
Changing the units of an existing areaAll units will automatically be converted to the new ones. However, accuracy loss may occur. The coordinates are stored in the xml file, in text format and in the selected units. Example: if the units were initially stored in DM.m and converted to DMS, they will lose accuracy. Converting back to DMm will not recover the accuracy.
Accepted hemisphere codes are N, n, S, s, E, e, W, w. For
input, they can be placed before or after the coordinate.
Coordinates in the XML fileAn xml file uses a text coding such as UTF-8 for symbols such as a double quote. This makes it more difficult to read, when opened from a simple text editor.
A double quote can’t be used in an xml data field, because it would be considered as the end of the data filed. Because of that, AspEdit replaces all double quotes with a # symbol. For example: 51°06'05”N will be written as 51°06'05#N in the xml file. If you manually edit the file, take care to adhere to this convention.
