Hey everyone, I am completely new to IMC
and map making. We are heading to a remote location in Canada this year and after 30 hours of failure I cannot figure out how to build a very basic map that will display in my Lowrance Elite
5 chirp. My primary objective is to use the map to navigate the lake and record my sonar during the trip.
I can download what I believe are shape files from http://atlas.nrcan.gc.ca/toporama/en/index.html
. I'm trying to cover Lake Windermere in Ontario. After I downloaded the files i converted the .shp files to wg84 with Qgis per the IMC instructions document. The went to IMC and added the shape files. In attribute mode I set u_limit to 19 and l_Limit to 0. New shape files were created which I then went back to vector mode and added the newly created shape files then clicked build and one large.at5 file was created.
Again I'm new to this and willing to put in the time to learn but after scouring the web for help I can't figure out how to troubleshoot. Any help or guidance would be greatly appreciated.
