Map Projection
The earth is a curved surface and maps are displayed on flat screens. In order to minimise the resultant distortion, map makers use a set of rules to project the curved surface onto a flat plane. This map uses "Iso-Rectangular Projection based on WGS84." (i.e. Lines of Latitude are always horizontal and lines of Longitude are always vertical.)
Map Accuracy
Although most points on this map are accurate to within about 15m, the map cannot be regarded as reliable for the following reasons...
  • Areas of the map are based on sketches rather than accurate data (especially in relation to proposed developments and unfinished roads.)
  • The basic GPS used to record parts of the map offered about 10m accuracy "at best" and GPS "drift" often resulted in "approximated" positions
  • The gap betwen some important features had to be increased due to visual limitations of the map scale.
  • The map makes extensive use of Open Data sources which use a variety of alternative projections. There are accuracy limitations when converting to/from unknown projection systems.
  • Coordinate data was unavailable for some data sources and location estimates were often based on address postcodes.
  • A typical minor road is about 5m wide but represented by a thin line on the map. (Wider lines reduce the space available for road names and other features.)
  • There are errors incurred due to the mapping process and I do not have the budget/time to find every problem.
  • You are welcome to suggest corrections or improvements relating to any content on this site.
Scrolling the map
There are 8 arrows displayed around teh outer edge of the map. Click or tap on any arrow to scroll the map in the indicated direction. This is a large scale map and covers the entire town, it may require more than one click to find your target. If some of the arrows disappear, you have reached the end of of the map.
GPS Coordinates
If your device has a mouse, you can obtain approximate GPS coordinates by placing the mouse pointer on any map location. The latitude (N) and longitude (W) will appear near top right of the map.
If you have a touch screen device (typically a phone or tablet,) the coordinates will appear when you tap on any map location. The latitude (N) and longitude (W) will appear near top right of the map.
Finding Locations
There is a list of locations and buildings in the left hand margin. When you click on any item in the list, the map will automatically scroll to the correct position and a red circle will indicate the location. If you start typing in the text box directly above the list, the computer will remove any items from the list which do not match your search. You can reset the search list by deleting evey letter, (including spaces), from the text box.
