Convert NM2 to SHP

Understanding the nm2 and shp file formats

NM2 files are navigation map files used primarily by Navitel Navigator, a GPS navigation software. These files contain map data, including roads, points of interest, and geographic features, optimized for use within the Navitel ecosystem.

SHP files, or shapefiles, are a popular geospatial vector data format developed by Esri. Widely used in GIS (Geographic Information Systems), SHP files store geometric location and attribute information of geographic features such as points, lines, and polygons.

Why convert nm2 to shp?

Converting NM2 to SHP allows users to utilize navigation map data in a wide range of GIS applications, enabling advanced spatial analysis, editing, and visualization beyond the capabilities of Navitel Navigator.

How to convert nm2 to shp

Direct conversion from NM2 to SHP is not natively supported by most GIS software. The process typically involves two steps:

1. Extract data from NM2: Use a specialized tool or script to convert NM2 files to a more common GIS format, such as KML or GPX.
2. Convert to SHP: Import the intermediate file (KML/GPX) into GIS software and export it as a SHP file.

Recommended software and tools

• NM2 Converter: A third-party tool (such as Navitel NM2 Converter) can extract data from NM2 files and export to KML or GPX.
• QGIS: A free, open-source GIS application that can import KML or GPX files and export them as SHP files. Use Layer → Add Layer → Add Vector Layer to import, then Layer → Export → Save Features As... to export as SHP.
• GDAL/OGR: Command-line tools for advanced users to convert between geospatial formats, including KML/GPX to SHP.

Step-by-step conversion process

1. Use NM2 Converter to extract your NM2 file to KML or GPX format.
2. Open QGIS and use Layer → Add Layer → Add Vector Layer to import the KML/GPX file.
3. Right-click the imported layer and select Export → Save Features As....
4. Choose ESRI Shapefile as the format and specify the output location.
5. Click OK to complete the conversion.

Conclusion

While there is no direct NM2 to SHP converter, using a combination of NM2 extraction tools and GIS software like QGIS provides a reliable workflow for converting navigation map data into the widely supported SHP format.
