Ich habe im folgenden Text 4x "map". Wie ist jeweils die richtige Übersetzung bitte?

Members use a GPS device to "map" the Wi-Fi and cellular landscape in their neighborhoods. Once a user synchronises their data it is made available to all the other users of the network so that a GPS device is not required for location purposes of that area in the future. In rural areas, most users are located through phone positioning from GSM cellular towers, and in densely populated urban areas users are primarily located using Wi-Fi signals. The current XX network is growing rapidly and today contains more than 10 million "mapped" Wi-Fi access points. Most urban cities in the U.S., Canada and Western Europe have already been completely "mapped". The XX software does not attempt to gain access to the Wi-Fi networks it "maps", and neither YY's Technology nor XX collect or
store any personally identifiable information about the Web visitor being located or about the owner of the Wi-Fi network.
