Geo Positioning and Real World Coordinates
Previous Topic  Next Topic 

Many maps are geo positioned, and this makes it possible to determine real world coordinates (longitude and latitude) for the controls and other objects that can be placed on the map.  This is very useful when exchanging data with GPS based applications, such as for example route choice apps.


Condes supports geo positioned maps and automatically reads geo positioning data from the map file if such data is present:


OCAD map files can contain geo positioning data, which Condes can use right away.   If the coordinates are defined in the UTM coordinate system, then Condes can translate the coordinates to longitude and latitude.  Condes does not support translation from the local coordinate systems that are defined by a number of countries, and which may be used when drawing the OCAD map.


Bitmap files can be accompanied by a so-called "World File", which contains the UTM coordinates for the top left corner of the bitmap.  Condes can use these coordinates.    The World File does not contain the so-called UTM zone, so you need to enter the UTM zone directly into Condes.  A number of web sites can help you determine which UTM zone you are located in.  Search for "UTM Zone" on the internet.   If Condes finds a World File, it asks you to enter the UTM zone.  There is a setting in the Application Settings dialog that lets you save a default UTM Zone to be used for bitmaps.


In the Course Layout Editor, the real world coordinates for the mouse pointer is shown in the status bar below the map pane, when the map is geo positioned.


When exporting, Condes puts the real world coordinates for each control into the file:


IOF XML files.  If the latitude and longitude are available, then these will be used.  If not, the "raw" coordinates will be used.


Bitmap files.   A world file with the same name, and appropriate extension, will be created.  The world file contains the real world coordinates for the top left corner of the map.


SVG files.  If the latitude and longitude are available, then these will be used.  If not, the "raw" coordinates will be used.


KMZ files.  Latitude and longitude must be available.  This means that the world coordinate system used must be UTM.


In order for Condes to provide geo positioning data in the exported file, the requisite is that the map is geo positioned.  In order to show longitude and latitude, the real world coordinates need to be in the UTM coordinate system.
