gpsmap reads GPS and Network XML datafiles and plots networks on downloaded vector maps or satellite photos or user-supplied images.


-h, --help
Display usage
-v, --verbose
Verbose output
-g, --config-file FILE
Use alternate config file FILE
-o, --output FILE
Image output file
-f, --filter LIST
Comma separated list of MACs to filter
-i, --invert-filter
Process only MACs specified in the filter list
-F, --typefilter LIST
Comma separated list of network types (ap,adhoc,probe,turbocell,data,unknown) to filter
-I, --invert-typefilter
Process only MACs and types specified in the filter list
-z, --threads NUM
Spawn NUM threads for power interpolation calculations
-N, --pure-avg-center
Use old pure-average center to guess the center of a network by averaging all of the sample points, instead of the new code which tries to find the most relevant cluster of sample points.
-S, --map-source SOURCE
Source to download maps from (-1 = Null; 0 = Mapblast; 1 = MapPoint(broken); 2 = Terraserver; 3 = Tiger Census; 4 = Earthamap; 5 = Terraserver Topographic). Default: 4
-D, --keep-gif
Keep downloaded GIF file
-V, --version
Version of GPSMap


-c, --coords LAT,LON
Force map center to LAT,LON instead of automatically calculated location
-s, --scale SCALE
Force map scale of SCALE instead of automatically calculated scale
-m, --user-map MAP
Use custom map file instead of downloading one. If center and scale are specified in the map title they will be used.
-d, --map-size X,Y
Download map at XSIZE,YSIZE. Default: 1280x1024
-n, --network-colors COLORS
Color networks by COLORS (0 = Random rotation; 1 = Color based on WEP and factory default; 2 = Color based on network channel). Default: 0
-G, --no-greyscale
Don't convert map to greyscale
--color-saturation PERCENTAGE
Set background map image color saturation. 0 is greyscale, 100 is full normal colors.
--map-intensity [-]PERCENTAGE
Set background map intensity. Negative percentages cause the map to be layered over a black background, while positive percentages cause the map to be layered over a white background.
-M, --metric
Download map with metric measurements (if possible)
-O, --offset XOFF,YOFF
Offset map by XOFF,YOFF pixels.


-t, --draw-track
Draw travel track
-Y, --draw-track-width WIDTH
Travel track width. Default: 3
-b, --draw-bounds

Draw estimated range circles
-R, --draw-range-opacity OPACITY
Opacity to draw range circles with. Default: 70
Feather the range circles out into transparency
-u, --draw-hull
Draw convex hull for each network
-U, --draw-hull-opacity OPACITY
Opacity to draw convex hull with. Default: 70
-a, --draw-scatter
Draw scatter plot of data points
-A, --draw-scatter-opacity OPACITY
Scatter plot opacity Default: 100
Feather the edges of scatterplot circles. VERY SLOW.
-B, --draw-scatter-size SIZE
Draw scatter at radius size. Default: 2
-Z, --draw-power-zoom
Power based scatter plot range for scaling colors [Default: 0] 0 determines upper limit based on max observed for network 1-255 is user defined upper limit

-P, --draw-power-opacity OPACITY
Interpolated power opacity. Default: 70
-Q, --draw-power-res RES
Interpolated power resolution. Default: 5
-q, --draw-power-colors COLORS
Interpolated power color set. (0 is a ramp though RGB colorspace; 1 is the origional color set; 2 is weathermap radar style). Default: 0

Draw dot at center of network range
-E, --draw-center-opacity OPACITY
Center dot opacity. Default: 100
-H, --draw-center-size SIZE
Center dot at radius size. Default: 2

Draw network label types, comma-seperated list. Labels are drawn in the order given. Valid labels are bssid, ssid, info, location, manuf.
-L, --draw-label-orient ORIENT
Label orientation (0 upper left, 8 lower right) Default: 7
-k, --draw-legend
Draw map legend
-K, --draw-legend-opacity OPACITY

-F, --feature-order ORDER
String representing the order map features are drawn. (p: interpolated power; t: tracks; b: bounds; r: range circles; h: convex hulls; s: scatter plot; c: center dot; l: labels) Default: 'ptbrhscl'.



Draws a blue track along the traveled path, based on the track data saved by Kismet.


Draws the bounding rectangle around the extreme points of each network.


Estimates the range of a network based on the average center and the distance to the closest extreme corner. Not exact, but often useful for estimating the range of the network.


Convex hull of all sample points for each network. This will display the exact detected range of the networks.


Draws a dot for every detected packet point.


By far the most CPU intensive, power interpolation forms a grid over the image and attempts to interpolate the power for points that aren't directly sampled. For this graph to be a reasonable representation of reality, samples around the entire area, preferably forming a grid or mesh, should be taken.


Simply draw a dot in the averaged center of each network


Labels are drawn in the order requested in the list. Labels are drawn based on the center of the network and the label orientation. There is some logic to attempt to prevent label overlap, but on extremely crowded maps it will be unavoidable.


Draws a legend on the bottom of the map with the coordinates, scale, total sampled networks, networks visible on the current plot, and dynamic information based on the plots selected and the network color methods requested.


While not technically a bug, source 1 (MapPoint) are nonfunctional. The vendors have changed their serivice in such a way that it is impossible to download the map images from them. GPSMap still supports these sources, but ONLY for predownloaded images that may have been kept previously. Attempts to use these sources when a user map is not available will fail.
