| Unit: | SDL_geomap |
| Class: |
TGeoMap |
| Declaration: |
procedure WriteCalDataToOpenXMLFile (var OutFile : TextFile; CreateHeader: boolean; DataID: string); |
The method WriteCalDataToOpenXMLFile writes the calibration data to the open text file OutFile using XML syntax. If the parameter CreateHeader is TRUE a minimum XML header is generated. CreateHeader should be set to a FALSE value if the map data is to be appended to an existing XML file. The parameter DataID holds a unique identifier which is stored as the attribute "id " of the <geomap> tag.
WriteCalDataToOpenXMLFile generates the following tags:
| XML Tag |
Description |
| <geomap> |
the root element of the map data. It contains the following attributes:
sig signature; is always "SDLCSuite"
vers version string
id name of geomap instance as defined by the parameter DataID
model calibration model
map path to map image
caption caption of map
example: <geomap sig="SDLCSuite" vers="1.0" id="mjcalmap" model="conicconformal"
map="albania.jpg" caption="Albania 1:200000"> |
| <corners> |
coordinates of the corners of the map (in latitude/longitude values)
example: <corners>
[36.10760,14.19668] [35.95435,14.10704]
[35.77225,14.54025] [35.92780,14.63435]
</corners> |
| <resolution> |
specifies the resolution of the map in meters per pixel
example: <resolution>13.2311</resolution> |
| <calline >
|
parameters of a calibration line (for the parabolic interpolation model)
type
kind of the calibration line (meridian or parallel)
value associated value (longitude/latitude)
npoints number of calibration points
example:
<calline type="parallel" value="36" npoints="3">
[278,403] [484,298] [682,198]
</calline>
|
| <calquads >
|
calibration parameters for the biquadratic polynomial model)
npoints number of calibration points
example:
<calquads npoints="2">
[3.9222,-37.9771,555,231] [-13.8222,-32.1771,165,831]
</calquads>
