Tools
Here are diverse tools, which I originally have made for myself, but which might be useful for others too. Similar tools exist in the web elsewhere, but I have made these in my own way.

|---|---|
| Coordinates conversion | Converts latitude / longitude coordinates between three commonly used notations: 1) degrees, minutes & seconds (DMS), 2) decimal degrees, 3) integer degrees and decimal minutes. |
| Distance calculation | Calculates of the distance between 2 locations with known latitude/longitude coordinates |
| Colour definition tool | This colour tool facilitates the task to define web page element colours, which fit to each other. It also helps to find a text colour, which is well distinguishable with a certain background colour. |
