More advanced users like surveyors or explorers who want to use Locus Map also for some specific tasks have possibility to use custom coordinate systems for coordinate transformations.
Currently these systems are used only for display/editing of coordinates, not for map projections. So it's not possible to re-project map to a different coordinate system.
For coordinate definition a configuration file stored in Locus root directory and called config_projections.cfg is used.
# Configuration file (advanced settings) for Locus application # allows to specify map projections, based on EPSG code. If you need some # more specific projection, contact us # # every line should contain syntax and values have to be separated by '|' char # # 'type of definition' | 'EPSG code' | 'name' | 'description' | 'country' # # where # 'type of definition' is currently 1 # 'EPSG code' - known code from (eg.) http://spatialreference.org/ # 'name' - visible name # 'description' - visible description in list # 'country' - country of usage for sorting in list # ----------------------------------------------------------------
Example of the file:
# header from above 1|2391|Finland zone 1|EPSG:2391|Finland 1|2392|Finland zone 2|EPSG:2392|Finland 1|2393|Finland Uniform Coordinate System|EPSG:2393|Finland 1|2394|Finland zone 4|EPSG:2394|Finland 1|3067|TM35FIN|EPSG:3067, UTM35 / GRS80|Finland 1|3857|Pseudo-Mercator|EPSG:3857,900913, WGS84 / Sphere|World 1|31467|3-degree Gauss-Kruger zone 3||Germany
Tested coordinate systems Feel free to send us EPSG codes (definitions) that you used, tested and they worked fine for you.
