C-MAP Genesis is a marine mapping program that empowers you to create custom, high-definition fishing maps from sonar data recorded with a compatible sonar/GPS unit on your own boat. After recording sonar data, your sonar files are uploaded to our cloud-based database where it is combined with data collected from our community of boaters just like you. The maps produced by Genesis are the most accurate on the market and allow you to customize your maps that highlight features of interest to you, such as specific depth ranges, vegetation, or bottom hardness. Your maps are then downloaded and used on your sonar/GPS unit to catch more and bigger fish!
If there’s currently no map of your favorite waterbodies, the benefits are immediately apparent. Finally, you can know what’s below, and the best spots to go! No more wishing or waiting for a company or the government to map the waters most important to you. If there is a map already of your favorite waterbody, how accurate is it? Ever found a hump, ditch or drop-off that’s not on your map? With C-MAP Genesis, you can create 1-foot contours you can trust, freeing you to unlock all the secrets of your favorite waterbody.
To make the best possible C-MAP Genesis custom contour map of your favorite lake, pond, reservoir creek arm or river section, drive your boat just under 10 mph, make shore-to-shore up-and-back trips spaced pretty closely together, and record small sonar logs with the correct settings dialed-in on your Lowrance, Simrad or B&G GPS/chartplotter. If you are on a reservoir, your map will look better if you drive the river and/or creek channel also. Mapping is really based on your objectives – slower speeds and closer boat paths result in more-accurate maps.
No. While a strategic survey will create the best map, it is not required to map areas you fish frequently. It’s very easy to map while you fish – just remember to insert an SD card into your sonar/GPS unit and press “record” every time you go fishing. Sonar data recorded during multiple trips on the water over time can be automatically merged into a Social Map chart or a private, encrypted map that only you can use. That way, you build up a detailed map over time as you are on the water.
The traditional sonar setting of 200khz or High CHIRP can be recorded in an .SLG, .SL2 or .SL3 digital file, which we call a “sonar log.” Sonar logs contain the requisite sonar and GPS data to create a C-MAP Genesis map. While StructureScan data can enhance a C-MAP Genesis chart, it cannot be used alone to create a chart.
Following upload of a sonar log file, Genesis Edge subscribers can usually expect a map in about 20 minutes, depending on server demands and how many people are uploading files at the same time. A slow Internet connection and/or exceptionally large sonar files can slow the automated map-creation process.
C-MAP Genesis makes this process very simple. When viewing any map in your Dashboard, click on the “Merge Trips” tab. You can select individual trips to merge, but most just choose the top button next to “Trip Title,” which selects all of your trips on that waterbody. You can select a buffer distance that fills in gaps in your map – but use it sparingly to ensure accuracy.
When new trips for Social Map are uploaded our trip processing service will look at existing data, then automatically create and apply an offset. For Private Trips, use the “Data Offset” tab and the processing system will generate a recommended offset that you can apply or if you want to apply a manual offset. Here’s how to apply a manual offset:
Example 1: For a transducer placement of 8 inches below the water line, enter 0.667 feet.
Example 2: If the water level is down 4 feet below normal, enter “4" … if on the next trip the water level is up 2 feet, enter "-2"
- Log-in to your Genesis Dashboard
- Scroll down until you see “PLOTTERS” on the right-hand side of the page
- Click the button labeled “Add Device”
- Type in a nickname for the sonar/GPS unit you are registering. Example: “HDS-12 Bow”
- Click the down-arrow in the “Model” field and scroll down to highlight the model of your unit
- Type in your unit’s Serial Number* in the field provided (Tip: Letters are case sensitive; look twice to distinguish between a letter O and number 0; in most cases it’s the letter)
- Type in your unit’s Content ID Number* in the field provided
* Both the Serial Number and Content ID Number can be found on your unit’s “About” page. To learn how to find that page, see the next question & answer.
- Power on you sonar/GPS unit
- Press the “Pages” button to get to the Home Screen/Main Menu
- Press “Settings” (located on the lower left-hand corner of the screen)
- Scroll down to the bottom of the page and then press “About”
- In most compatible units, your Serial Number and Content ID Number will be the third and fourth line-items, respectively, in the list in the window that pops up.
Each sonar file uploaded to your account will be automatically tagged with weather, temperature and barometric-pressure readings taken while you were on the water. You can access and analyze all the data in your C-MAP Genesis dashboard to determine what conditions contribute to productive fishing.
Usually this is caused by the chartplotter’s serial number and content ID number not being entered correctly.
Tip: Letters are case-sensitive and it’s a zero, not the letter "O". Make sure the numbers on the “About” screen of your chartplotter match what has been entered in My Plotters. Once they match, generate your map again.
C-MAP Genesis is not available in coastal waters around Finland, Norway and Sweden.
“The cloud” is simply a network of several computers and servers which to which you connect via the Internet. Cloud storage of data has a number of advantages:
- You don't have to maintain or upgrade the software. If we make any improvements to the Genesis software, they are instantly available to you without having to do a software update.
- We back up all of your data, so if you drop your SD card overboard or lose it, none of your data is lost.
- Our Quality Control techs have access to view your maps. This allows the QC team to review your data for incorrect data. If you need any assistance, they can log in to your map and assist you, as needed.
- Social Map: All boaters can work together to provide the best mapping possible for everyone.
No. While C-MAP Genesis provides increased bottom-feature and depth details for the waterbodies you care about, it’s not designed for navigation. C-MAP Genesis maps should be used only to enhance activities on the water and not as your main navigation tool.
