Points Of Interest (Yellow Pages) are currently
unavailable for South American maps.
US Maps
The typical US map file (*.ttm) name consists of four parts:
1. Most files begin with "gdt". GDT supplies US street maps.
2. Next is the number that designates the state. It could be one or two digits long. For example, "15"
would be Hawaii, whereas "8" would be Colorado.
3. Next is a four digit number that designates the county within that state.
4. The last part designates the type of map the file contains.
_nr maps contain roads.
_pl maps contain terrain.
_yp maps contain landmark Yellow Pages.
_hy maps contain highways.
An example file would be "gdt36057_pl.ttm," which is a polygon file for Montgomery County in
the state of New York. To determine what the numbers are for each county, use your PC and
go to
Transfer > Storage Maps > Streets . Select United States as the country and pick your
state. You will then get a list of counties with numbers beside them.
•
" \US\State#_Abbreviation "
Street maps, polygon files, and YP files for each state are stored here.
Example: "\US\25_MA" is the directory for Massachusetts maps.
"\US\06_CA\gdt06081poi.ttm" is a landmarks map for San Mateo County found in the California maps
folder.
•
" \US\Highways "
Highway files organized by state.
Example: "\US\Highways\tx__hy.ttm" is the file for Texas highways.
Yellow Pages
Yellow Pages maps are named corresponding to the county and US state they are located in. They are
organized in the same manner as typical US states, and have the same file number as those specific
counties. For example, tla08097_yp.ttm would correspond to the files gdt08097_nr.ttm and
gdt08097_pl.ttm.
•
"YP\US\State#_Abbreviation\"
Directory that holds all the Yellow Pages for each US state.
Example: "YP\US\13_GA\tla13007_yp.ttm" is the Yellow Pages file for Baker county in Georgia.
Canada Maps
The typical Canada map file (*.ttm) name consists of four parts:
1. Most files begin with "gdt." GDT is the database that supplies our maps.
2. Next is country name "Canada."
3. Next is a three digit number that designates the province.
4. The last part designates the kind of map the file contains.
_nr maps contain roads.
_pl maps contain terrain.
_hy maps contain highways.
