DESCRIPTION

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

USAGE

-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

USAGE (IMAGE OPTIONS)

-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.

USAGE (DRAWING OPTIONS)

-R, --draw-range-opacity OPACITY: Opacity to draw range circles with. Default: 70
--feather-range: 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-scatter: 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

-E, --draw-center-opacity OPACITY: Center dot opacity. Default: 100
-H, --draw-center-size SIZE: Center dot at radius size. Default: 2
-l, --draw-labels LIST: 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: Legend opacity [Default: 90]

DRAWING METHODS

TRACK DRAWING

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

BOUNDING RECTANGLE

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

RANGE CIRCLE

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

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

SCATTER PLOT

Draws a dot for every detected packet point.

POWER INTERPOLATION

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.

NETWORK CENTER

Simply draw a dot in the averaged center of each network

LABELS

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.

LEGEND

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.

BUGS

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.
