include the state, district, section, lot number and certified 
plan number where it is located . There two layers required 
to be integrated into Garmin database which is the boundary 
and the lot layer, as the format of spatial database in Garmin 
is in .mif (Map Info Interchange) format both of the map Info 
layer are required to be converted to .mif format as shown in 
Figure 2. MIF file is a MapInfo Interchange Format Data 
which is used for a map and database exporting file format of 
MapInfo software product and this format is accepted in 
Garmin Navigation System.
MapInfo Professional Interchange Format (MIF) is an 
ASCII file format that can fully describe a MapInfo 
Professional database. Both graphic and tabular data are 
exported into MIF files. The graphic data is in a file with a 
“.mif” extension, and the tabular data is in a file with a 
".mid" extension. This versatile format allows generic data to 
be attached to a variety of graphical items. Since it is ASCII, 
it is editable, relatively easy to generate, and it acceptable on 
many topographic mapping software such as Global Mapper.

V. Marking point of interest 
GIS data which has been converted into MIF format is 
required to go through another conversion this time it has to be 
in GPX format. GPX stands for "GPS Exchange Format," a 
standardized data format for the exchange of waypoints, routes, 
and tracks between applications and Web services on the 
Internet [3]. Since MapInfo is not capable to convert data 
directly to GPX format it is necessary to have third party 
software that capable to support MIF and GPX data format. 
In 
this study the conversion was done using Globbal Mapper 
software as as it support both of the format. Under tool of 
Export Vector data, the Export GPX (GPS Exchange format) 
choose as shown in Figure 3. and select the MIF data to be 
converted .This format is the format that can be accepted in 
Portable GPS and Map Source.
Figure 3. Creating GPS data exchange format 
The data that required to be integrated into Garmin 
navigation system can be selected either by drawing a box or 
directly loaded using radio button. In this study, the radio 
button of all loaded data was ticked and the area coverage by 
the specific coordinates. Figure 4 it shows all loaded data will 
be exported and the data will be saved. 
Figure 4. Defining the area coverage of the selected area 
After converting the data into GPX format is it required to 
create point of interest on the land parcel as the destination to 
be selected by the user. The point of interest is consider as the 
destination when a surveyor looking for the lot to conduct a 
cadastral surveying. The creating point of interest can be 
performed using way point tool in Map Source. The point then 
marks at each of lot and rename it referring to its lot name. In 
Figure 5, it shows the result of all POI lot that had remarked 
and renamed.
