This data set has much more detail than WorldLoRes, at least for North America. Because of the file size, it is meant for users with fast Internet connections and large machines. Namerhires1.1 requires Tkgeomap1.7 and Visky.

NAmerHiRes creates a MapData menu with the following items:

• Show lakes and rivers - determines whether lakes and rivers are drawn. Upon selection, this item becomes Hide lakes and rivers.
• Show highways - determined whether highways are drawn. Upon selection, this item becomes Hide highways.
• Show places - determines whether places are visible. If places are shown, the text display below the map identifies the place nearest the cursor.
• Find place - creates a dialog box where the user can enter a text pattern. Visky will perform a case insensitive regular expression search for place names matching the pattern. If it finds one, the place is put at the center of the map with the '+' marker over it. If several place names match the pattern, the names are displayed in a list box and the user selects the desired place by double-clicking it. Note: the list box has no scroll bar - the viewed region is adjusted by dragging.
• Dot size - selects dot size in pixels for displaying places. default sets the value to that chosen in the 'Widget->Dot size' menu.
• Colors - accesses a dialog box for adjusting the colors of various items. Color selections are saved in a file named $HOME/.mapdata/colors/NAmerHiRes.tcl, which is used to set colors next time the program runs. When visky starts, it backs up this file to $HOME/.mapdata/colors/NAmerHiRes.tcl.bu, which can be used to revert to the original colors if desired.
