Map Navigator

Map Navigator is a geographic data viewer and editor, equipped with tools for measurement, exploration, and routing. The software is written in Java and requires JAVA 8 or later to be installed on the PC.
The goal of Map Navigator is to bridge the functionality between Google Earth and established GIS applications such as ArcGIS, QGIS, and OpenJUMP.
It is engineered to be used as both didactic software and a professional-grade tool.

List of Functions

Explore popular world tile servers like OpenStreetMap, OpenTopoMap, Bing Map, ArcGIS World Imagery, among others, and navigate using zoom-to-area, zoom-to-coordinate, and pan tools.
Zoom to an address using the OpenStreetMap Nominatim service.
Save and recover views in different times of using software witha dedicated set of tools
Save views as georeferenced (GeoTIFF, JPG, PNG, GIF, KMZ) and non-georeferenced (SVG, PDF) image files.
Print the current view.
Geocode points using the OpenStreetMap Nominatim service.
Measure polyline length, area, angle, angleby goniometer and azimuth directly in the view, using defined algorithms (Vincenty's algorithm, for lengths, and Shoelace algorithm, for areas, angles algorithms convert geographic coordinates to projected ones)
Calculate routes between two user-defined coordinates using the Open Source Routing Machine service (currently supports only car routes).
Use MediaWiki to find Wikipedia articles near specific coordinates. Due to API restrictions, the search radius is limited to 10 km from the view's center, with a maximum of 50 results per search.
Load vector files (such as Google Earth KML/KMZ, GPS GPX, AutoCAD DXF, SHP and geographic CSV) into the view as vector elements.
Load raster files (including popular image formats like JPG, PNG, BMP, GIF, TIFF, and KMZ image overlays into the view as raster elements.
Draw geographic elements like points, lines, and polygons with user-defined styles and transparency.
Add basic Google Earth metadata (name and description) to geographic elements.
Point styles according OpenStreetMap and Geological CARG symbology.
Use multiple edit tools to edit and convert geometries, extract centroids, extract segments, convert lines to polygons, create holes/islands, and cut lines or polygons, draw adicant polygons, etc.
Extract topographic profiles from a polyline using EU-DEM (for Europe) and ETOPO1 (for the rest of the world, including seafloor).
Save vectors as Google Earth KMZ , GPX, DXF and geographic CSV data.
Save raster to Google Earth KMZ files
