File Structure
Previous  Top  Next

The TeleType program looks for the *.ttm map files in certain directories, and moving these maps from these locations will make it difficult or impossible to load or transfer maps within the program. All map directories listed here are expected to be in C:\Program Files\Gps\Maps on the PC and in either \Maps or \Storage Card\Maps on the PDA.

warning
Make sure you have the latest maps installed, since v062005 of the TeleType GPS software is not compatible with older version maps.


warning
Points Of Interest (Yellow Pages) are unavailable for South American and Canadian 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 kind 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.  


·"\Canada\ProvinceName"  
Canadian street maps organized by province.  
Example: "\Canada\Quebec" is the directory for maps in Quebec province.  
   "\Canada\BritishColumbia\gdt_canada_059_nr.ttm" is a street map for the entire province of British Columbia.  
 
 
 
·"\Canada\Highways"  
Canadian highway maps.  
Example: "\Canada\Highways\ab_hy.ttm" contains the highway file for Alberta.  


Europe Maps

 
Each European country file begins with three letters that represent the country name, which may be followed by a number depending on the number of maps for that country. For example, maps of Ireland will begin with "irl" in the file name, while maps of Germany will begin with "deu" and are followed by a number. These are then followed by one of the following:  
 
   _nr maps contain roads.  
   _pl maps contain terrain.  
   _pi maps contain Yellow Pages.  
   _hy maps contain highways.  
 
 
·"\EUR\CountryName"  
Street maps and Yellow Pages files for each European country.  
Example: "\EUR\France" contains files for locations in France.  
   "\EUR\Switzerland\che_pi.ttm" contains Yellow Pages files for a region in Switzerland.  
     
 
 
·"\EUR\Highways"   
Highway maps for each European country.  
Example: "\EUR\Highways\gbr21_hy.ttm" contains the highway files for an area in Great Britain.  
 
Note that Germany, Spain, Finland, Great Britain, France, Sweden, Italy, and Norway have more than one highway file.
