Help using the address lookup feature

The geocoder has a few quirks you should be aware of when using it. Unfortunately, Google has yet to include geocoding -- that is, physical address -> lat/long coordinate conversion -- features in the current version of the Google Maps API. As a result, this means that the superb place lookup features present within the standard Google Maps interface aren't a reality for Power Map as of yet.

However, through the use of a very cool geocoding service, http://www.geocoding.us, Power Map is capable of locating and marking street addresses. The street address parser of the geocoder isn't as robust as that offered by Google, so several hints are worth keeping in mind in order to make using it a bit easier:

Map Controls

Left column options

  1. Enable dynamic dragging
    If this option is set, the map may be freely panned. Clearing this option prevents the map from being panned. The map may still be zoomed, however.
  2. Display small map control
    If this option is set, a directional map control with a central 'return home' button that does not include the zoom slider widget will be displayed. If the large map control is also displayed, the two controls will overlap with one another, but coexist happily together.
  3. Display large map control
    When this option is set, a large map control which includes four directional buttons, a 'return home' button, and a zoom slider will be displayed on top of the map. If the small map control is also selected for display, the controls will overlap with one another, but coexist happily together.
  4. Display map/satellite mode switcher
    This toggle switches between a street map view and a satellite/aerial photograph view of the the current map region.
  5. Display current zoom level
    Displays the current numerical zoom level of the map in the bottom right hand corner.
  6. Display current viewport bounds
    When toggled, displays four latitude/longitude coordinates describing the map region currently being viewed; top left corner, top right corner, bottom left corner, and bottom right corner.
  7. Enable popup info windows
    Toggles whether or not popup info windows are able to display (but seems to have issues with preventing their appearance at the present time!)
  8. Display current lat/long coordinates
    Displays the lat/long coordinates at the center point of the map region currently being viewed in a message area at the bottom left corner of the map.
  9. Clear all tracks and markers
    Clears all current waypoints and map movement tracks from the entire map (not just the region in view). No granularity here currently, but future versions will make it possible to excise overlay elements in a selective fashion...
  10. Display map movement track
    When toggled, this option causes a line to be drawn over points you traverse whilst wandering about the map. Untoggling the option prevents the line from being drawn, but doesn't erase previously drawn tracks.
  11. Display map movement track: Track color
    Determines the color of the map movement track. Color is specified by providing a standard hexadecimal HTML color string.
  12. Display map movement track: Track width
    Width of the map movement track in pixels. Changing this value (as with track color) will only affect track segments drawn subsequently.
  13. Display map movement track: Track opacity
    Opacity of the map movement track, specified as a floating point value from 0 to 1.0.
  14. Display distance travelled
    Displays distance traversed on the map in miles and kilometers in a message area below the map display.
  15. Display distance travelled: Reset distance travelled
    Clicking this link resets the distance travelled odometer to 0.
  16. Go to lat/long coordinate
    Centers the map on the latitude and longitude coordinate provided in the latitude/longitude text entry fields below this item when the 'Go to location' link is pressed.

Right column options

  1. Go to street address
    Typing a street address in this text entry field causes the address to be associated with its lat/long coordinate, the map to be centered over the location, and a marker to be created with an associated information window containing the physical address and associated lat/long coordinates returned by the geocoder.
  2. Set marker at lat/long coordinate
    Sets a marker at the lat/long coordinate specified in the latitude and longitude text entry areas below this option. Clicking 'Set marker' causes the marker to be created. Currently, this option does not pan to the location in which the marker was created, although this will be added as an option in the near future.
  3. Set marker at current location
    Places a marker at the centerpoint of the map region currently being viewed.
  4. Load and mark waypoints in XML file
    Given a set of waypoints in an XML file in the form:

    Where the lat attribute of the marker tag contains latitude, and the lng attribute of the marker tag contains longitude, place markers on the map in the locations specified.
