So, lets say you have imported a sonar recording for one portion of a lake. When you import a sonar recording into AutoChart, AutoChart converts your sonar recording (.dat) file to as AutoChart file (.acd). You don't really 'merge' maps in AutoChart. If you have made waypoints while fishing, and you want to see where those show up over your map, you CAN import your waypoints into AutoChart and see where your waypoints appear on the map. Got it.Īgain, waypoints and maps are different things. In the digital world, waypoints and maps have different file name extensions. In the map and compass world a map has the lat/long lines and coordinates are the intersection of the lines. To put it simply, maps and waypoints are totally different. If you don't have a lake map on your gps, waypoints still appear 'over' the bare background map. Waypoints, are a set of data points (Lat & Long), that appear over whatever background is on your gps depth finder. Basically, a map is a 'background image' that is oriented correctly with gps coordinates. Waypoints are completely different from maps. I'll try to break out your questions, and answer them one by one. Matzilla helped a little, with his description. I just don't get over here as often to be able to keep up with questions.Īnyways, Hanr3, part of your complaints about Humminbird, comes from your slim understanding about the difference between waypoints, maps, and side imaging/sonar data. I've helped a bunch of users over there with AutoChart questions. He's right though, the best resource for AutoChart related issues, is the BBC forum. Howdy fellas! Rickie asked me on BBC if I'd take a look over here and see if I could help Hanr3 with his AutoChart issues.
Your first step is to gain an understanding of these files. Waypoints, maps, and sonar data are all different types of files, and stored in different ways. I'm merely observing, that you don't know how waypoints are stored, or how maps are created or displayed. You need to gain a better understanding of how waypoints, tracks, sonar recordings, and background depth contour maps are used.ĭon't be offended by my comments either. They are to insert a map chip (such as lakemaster, navionics, or custom AutoChart), or blank sd cards to save waypoints to, or to save sonar recordings to, whatever. There are two card slots, but you're confused what they're for. You can export them to an SD card at any time.
Waypoints and tracks are stored in the memory of the depthfinder. My expectation is that one card slot on my unit is for the map with waypoints (ACP Card), the other slot is for a blank card so I can record the days route and analyze that data while off the water.
