AspEdit manual Coordinate
AspEdit 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.
The 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:
- DMS : degrees, munutes seconds
- DMS.s : degrees, minutes, seconds, decimal seconds
- DM.m : degrees, minutes, decimal minutes.
Units, upon input
- Upon input, AspEdit uses the coordinates in the area dialog
- The N/S and E/W hemisphere indicators can be placed either at
the front or at the end. If none is specified, N and E are
presumed. Don’t use a minus sign.
- Punctuation is very permissive. You can use any of the
following examples, in any combination (DMSs):
- N50°20’30.00” / N50.02.30.00
- When exactly 6 numerical digits without any punctuation are
given for latitude, or 7 digits for longitude, DMS is taken as
input unit. Example: 502030N will be read as
50°20’30”N, regardless of the selected units. Example for
longitude 0042030E = 004°20’30”E. Mind the zeros at the
Units upon output
- In the xml file, the selected units will be used
- In OpenAir files, the units will always be DMS
Changing the units of an existing area
All 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 file
An 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.
