Milsymbol generator wiki

The pages on this wiki describe the functionality and content of the Milsymbol generator as extended by the Military Tactical Graphics Czechia. Some information is valid for the original Milsymbol generator created by spatialillusions as well.

Documentation of used standards

In this project, we are using the MIL-STD-2525C standard for military symbols, specifically the Military Operation Tactical Graphics section. The relevant specification of this standard can be found on pages 329 - 761 in the following document: http://www.mapsymbs.com/ms2525c.pdf

Symbol generation

The generator uses a form which prompts the user to input necessary attributes. Here are some examples of GeoJSON and the corresponding symbols they generate:

Table of sample symbols

Image	JSON file	Description	Parametres
	Special point	A single placed point to map using GeoJson. Specifically, it is a "Special point" created in the unitgenerator, with FunctionID: GENERAL - POINTS - REFERENCE POINT - SPECIAL POINT	Parameters "sidc": ID specifying diagram type "distance": the size of the space on the map Coordinates Longitude Latitude
	Under sea	S single placed point to map using GeoJson. Specifically, it is an "ANM" created in the unitgenerator. FunctionID: GENERAL - POINTS - UNDER SEA WARFARE - SONOBUOY	Parameters "sidc": ID specifying diagram type "distance": the size of the space on the map Coordinates Longitude Latitude
	Ground zero / ambush	Combination of two objects, point Ground zero and ambush. Used just as example, not as a real visualization. FunctionID: GENERAL - POINTS - WEAPON - GROUND ZERO	Parameters "sidc": ID specifying diagram type "size": attribute specifying the size of the marker on the map Coordinates Longitude Latitude
	Canalize / bridge	Combination of two objects, point Bridge and LineString Canalize. Used just as example, not as a real visualization. FunctionID: CROSSING SITE/WATER CROSSING - BRIDGE OR GAP	Parameters "sidc": ID specifying diagram type "size": attribute specifying the size of the marker on the map Coordinates Longitude Latitude
	CFF zone / destroy	Combination of two objects, point Call for fire zine and destroy. Used just as example, not as a real visualization. FunctionID: DESTROY	Parameters "sidc": ID specifying diagram type "distance": the size of the space on the map "uniqueDestination": ID specifying exact location on the map Coordinates Longitude Latitude

General GeoJSON syntax

The outernmost tag for all diagrams is a FeatureCollection, which contains individual features with properties and geometry. A Feature collection may include only one feature, as seen on this abstract example:

{
    "type": "FeatureCollection",
    "features": [
        {
            "type": "Feature",
            "properties": {
                "property 1": xxx,
                "property 2": xxx,
                ...
            },
            "geometry": {
                "type": "Point",
                "coordinates": [
                        longitude,
                        latitude
                ]
            }
        }
    ]
}

Or it could be a combination of several features, like in this abstract example with two features:

    "type": "FeatureCollection",
    "features": 
    [
            {
            "type": "Feature",
            "properties": {
                "property 1": xxx,
                "property 2": xxx,
                ...
            },
            "geometry": {
                    "type": "LineString",
                    "coordinates": [
                        [
                            longitude,
                            latitude
                        ],
                        [
                            longitude,
                            latitude
                        ],
                        [
                            longitude,
                            latitude
                        ]
                    ]
                }
            },
            {
                "type": "Feature",
                "properties": {
                    "property 1": xxx,
                    "property 2": xxx,
                    ...
                },
                "geometry": {
                    "type": "Point",
                    "coordinates": [
                            longitude,
                            latitude
                    ]
                }
            }
        

    ]
}
