Geographic Information Systems (GIS) Files
The formats including GPX, and KMZ files are much more useful because these file types are geo-referenced. This simply means that each data point (or contour line) is linked to a specific geographic position on earth. For example, with this technology users can take data files, download them onto their smartphones or Garmin GPS, and use them to help find lakes and specific structure or depths. A GPS or offline mapping application on a smartphone is constantly updating geographic locations using satellites, therefore the software identifies locations even when out of cell service. For example, as users are boating in the summer or snowmobiling in the winter, the device(GPS or smartphone) will indicate the depth of the water at that exact location. This is a major fishing advantage.There are various programs available to display this data from free to paid subscriptions software/apps. Essentially, a KMZ file and a GPX file are the exact same thing, as they provide the same geographic information. The only difference is that KMZs are compatible with some applications while GPXs are compatible with others. Data is provided in both types to give users options so they can use their favorite applications/programs/software.
Smartphones are arguably the most popular user medium for displaying depth information. In order to visualize depth information on smartphones in locations without cellular service, an “Offline Map Application” will need to be chosen and downloaded. There are various programs available to display this data. Each user has their own preference. Listed are a few popular options:
Supported File Types: .kmz .kml
Offline Capabilities: Online Only
Attractiveness (Poor 0 – Excellent 3):
Contour Data: 3 Access Data: 3
General Comments: Appearance of data uploads are nice but will not work offline.

iOS Favorite Free App- Map Plus
Map Plus has been chosen as a smartphone example. Map Plus is only available on iOS devices but is free, with offline capabilities and is compatible with both .KMZ and .GPX files for all trail, contour and overlay data. Illustrated in the videos is how to import lake and access data after download using the “Map Plus” app, plus how to access basemap downloads for offline use and other setting features.
