As a Cartographer or Geospatial Analyst, I developed Backcountry Mapping to research custom Global Positioning System (GPS) mapping and web design technology.
GPS owners are limited by generalized nationwide commercial GPS maps such as Garmin's Street Atlas and 1:100,000 scale Topo maps.
The ability to create GPS maps from custom built detailed spatial data has proven extremely useful for navigating, in particular, Utah's backcountry.
I chose to concentrate on the state of Utah simply because this is where I am most likely to use the data. Garmin GPS receivers (GPSr) can display custom
designed points, lines, and polygons as well as a searchable fields and routable turn-by-turn GPS directions.
Geographical Information Systems (GIS) refers to a broad complex interdisciplinary
science of creating, quantifying, storing, and displaying information according to its spatial attributes. Through a conversion process,
relatively inexpensive
Garmin GPS units have the ability to display complex GIS spatial data (ie. geodatabase, shapefile, and .e00 files). In recent years, very sophisticated
geospatial software applications have emerged in the market aiding in complex spatial statistics, visualization, and storage. The next phase
is to take the data OUT of storage and get some real world use out of it.
So, GIS is recognized as the geospatial discipline,
while GPS is a tool for displaying GIS point, line, and polygon data with its accompanying attribute information. Essentially, all
spatial data on a GPS is GIS data.
