Dear HANA-dev-community,
one of my tables defines a VARCHAR column containing geo positions, e.g. N4711.4595E00709.0610. I found web page www.earthpoint.us/Convert.aspx which provides a conversion function for this kind of position. According to the conversion result, I assume my source position data is defined in the "degree minutes" representation.
Currently, I try to visualize the data stored along with this position in a UI5 application utilizing a map interface where I intend to place a marker at each provided position. The additional data should be displayed by a popup bound to those markers.
Now my problem is, that I'm not able to find a HANA-built-in conversion function to get the valid latitude/longitude values from the degree minutes varchar - similar to the conversion the mentioned web page provides. From my Point of view, doing this conversion manually along with a database selection is quite cumbersome, since there are various substring/locate/etc.-statements involved combined with various calculations (e.g. division by 60).
Therefore my question is, does a built-in HANA (spatial) function exist, which is capable of doing the desired conversion? Or maybe there's something like a simple workaround which I haven't thought of so far?
Many thanks in advance and beste regards,
Christian
