tMapper is a web-based application, porting C++ utilities that convert WW1 trench map references to locations that can be visited using a GPS, Google Maps or Street Directions.
This is a limited-release prototype. It supports single conversions, multiple conversions, elevation profiles, Google Street View, modern locations and Excel export. Known limitations appear below and may be addressed at a later date.
Home Page assumes that within the 1,000 yard grid square (abcd), all locations are written in double-digits. Eg b.37.11 is assumed to be 37 units left and 11 units upwards from the origin of grid 'b'. However, b.4.1 is assumed to be 04 units left and 01 units upwards. It must therefore be entered as b.40.10. However, the bulk import counts the number of digits and correctly converts these for you.
Single-Map displays a lengthy description that is removed after a few seconds. Clicking on the marker icon displays it once again. The link to McMaster University shows all trench maps for the sheet itself (eg Sheet 36c - Vimy).
Street View shows a requested location and a Google image. If the Google image is blank, it is because no camera has visited the location, such as in the middle of a field. Manually move the Street View control and all roads will appear highlighted in blue.
Multi-Map displays all single, multiple and elevation conversions. The table can be sorted by a number of columns.
Export: tMapper's menu bar allows you to export to Excel. If you have Excel loaded, it will load the tMapper CSV file for you. The 1st entry is always your single conversion. The next 2 are your elevation profile start and finish respectively. Entries The button within Utilities exports a blank CSV file.
Utilities: tMapper saves all conversions you have done and they are available on subsequent visits. If you wish to delete them, the 'Clear All Data' will remove these without warning. Note that all menu funcrions will continue to work but all maps will be blank as they contain no data. Once you have visited the home page and entered values, maps data will re-appear.
Concept Maps: tMapper's prototype displays concept maps that will either be modified to work with the user trench map references or removed.
