Based on the blog posted by Jeroen van der A on the inclusion of open source I have made a try to get some open street map into design studio. Here the first findings...
Does it work?
Yes, the good point is, this works. I had to switch back again to "DIV" based component model as the map API which I use (Modest Maps | Home) requires a div which is building a parent for the component. And I think SAPUI5 has some bug as the sizing of the HTML component is not working as expected - technically there is some DIV inbetween which has no real size.So for me a bit drawback in the API as the "DIV" api is a bit different and I cannot use the metadata property.

What is IN / What is not IN?
I had to learn that data SDK does not push yet attibutes of members to the client. And my test data source has the GOE-Attributes maintained as attributes on dimension CUSTOMER.
in release 1.4 lucky I have found a method which helps me to get the attributes in scripting. This means this component is not data based, but via "manual" scripting we can use it...
Here the code you need to use in order to dynamically add locations.
// insert madrit and SAP Headquaters in Walldorf
OSMAP_1.addLocation("MADRIT", "Madrit", "", 40.4, -3.7);
OSMAP_1.addLocation("WALLDORF", "SAP SE Headquaters", "SAP.jpg", 49.293417, 8.642384);
Example for 1.4 release:
var mem = CROSSTAB_1.getSelectedMember("0D_CUSTOMER");
// get attributes
var lat = mem.getAttributeMember("0LATITUDE");
var lon = mem.getAttributeMember("0LONGITUDE");
// calculate values
var latValue = lat.internalKey;
var lonValue = lon.internalKey;
// check if negative (as - is at the end and cannot be casted)
var latNegative = false;
var lonNegative = false;
if(latValue.indexOf("-")) { latValue = latValue.substring(0, latValue.length -1); latNegative = true;
}
if(lonValue.indexOf("-")) { lonValue = lonValue.substring(0, lonValue.length -1); lonNegative = true;
}
// convert to float after - is cut
var latValueFloat = Convert.stringToFloat(latValue);
var lonValueFloat = Convert.stringToFloat(lonValue);
// korrections as we have dummy data (only for the demo query)
latValueFloat = latValueFloat - 40;
lonValueFloat = lonValueFloat - 18;
// fix again the negative numbers
if(latNegative) { latValueFloat = latValueFloat * -1;
}
if(lonNegative) { lonValueFloat = lonValueFloat * -1;
}
// get the key and text from member
var key = mem.internalKey;
var tex = mem.text;
// add location (in 1.3 you need to make it in the startup of by hard coded coordinates)
OSMAP_1.addLocation(key, tex, key + ".jpg", latValueFloat, lonValueFloat);
// move map to the location
OSMAP_1.moveTo(key);

Summary
First Step to get a map is done, as next I try to play around with different map layers and perhaps some value painting on the map (assuming SDK will be improved for the attributes)
