Automated detection of the unknown early map projection
...The awareness of the map projection is primarily important for:
• refinement of spatial georeference for the medium- and small-scale maps,
• analysis of the knowledge about the former world,
• location of the incorrectly/inaccurately drawn map regions.
Sytem requirements:
• 2 GHz or faster 32-bit (x86) or 64-bit (x64) processor.
• 2 GB RAM (32-bit) or 4 GB RAM (64-bit) system.
• 120 MB available hard disk space.
• JDK 1.8 +.
• Internet connection (download speed > 2Mb/s
QNetMap is the library for displaying the map and the objects on it
...The project is based on the QMapControl library (http://qmapcontrol.sourceforge.net/) by Kai Winter.
To show the map QNetMap can use different providers like OpenStreetMap or other WMS servers. The map data can be downloaded from the Internet or from the disk cache.
User's own raster maps can also be used.
QNetMap supports layers so you can mix maps from different servers.
To enrich the map presentation you can draw your own objects in the given coordinates.
The development of the library was supported by "Sintels" LLC (ЗАО "Синтелс" -
http://sintels.ru) and OJSC "T8" (ОАО "Т8" - https://t8.ru). ...
