Is kismet what you want? If you have a GPS, it has a few utilities to make 
you a map.

# WHAT IS KISMET

Kismet is a 802.11b wireless network sniffer - this is different from a
normal network sniffer (such as Ethereal or tcpdump) because it separates
and identifies different wireless networks in the area. Kismet works with
any wireless card which is capable of reporting raw packets (rfmon
support), which include any prism2 based card (Linksys, D-Link, Rangelan,
etc), Cisco Aironet cards, and Orinoco based cards. Kismet also supports
the WSP100 remote sensor by Network Chemistry.

# FEATURES

    * Multiple packet sources
    * Channel hopping
    * IP block detection
    * Cisco product detection via CDP
    * Ethereal/tcpdump compatable file logging
    * Airsnort-compatable "interesting" (cryptographically weak) logging
    * Hidden SSID decloaking
    * Grouping and custom naming of SSIDs
    * Multiple clients viewing a single capture stream
    * Graphical mapping of data (gpsmap)
    * Cross-platform support (handheld linux and BSD)
    * Manufacturer identification
    * Detection of default access point configurations
    * Detection of Netstumbler clients
    * Runtime decoding of WEP packets
    * Multiplexing of multiple capture sources
