Hello Curado,

lcm and AT5 you can diplay together, but there is a problem with firmware version from HDS Units.
You must test it. Especially newer firmware versions on Gen2 make problems.
With help of a AT5 You can also display the lcm on Planner, but the depth values not correct appears.

But why You want to use lcm, if You have AT5?

First: lcm is dead!

You could use at5 with only one lcm. If you have more than one lcm on your SD, there will be more problems.

In a few days of practice you will create your maps as at5 in raster and vector, which is a much better idea than to use imperfect lcm's.

I think Matt look for side/structure scan in an next version!! wait and see!
You can make log of scan for that and kkep them!

I thought of using .lcm files to mark snags, roads and rivers. Can you draw lines or shapes with at5?

You can create anything you want. You simply need to create shapefiles in a GIS application (QGIS is free) or GPSMapedit, and include them in your fileset in IMC. I would suggest a different shapefile for each object type.The new attribute facility in IMC will sort out the attributes for you. You'll need the manual.

Good luck

Trevor

Edit - If you wants a small tutorial on how to do this kind of thing I'll put one on my website. You will need the original data that you created the lcm with.

Trevor has right! Much more possibilities as lcm.

But if You need roads and other topo element, check for OSM file. These are ready for use. You can create AT5 simply from this source with IMC: element selection as pbf file or single element as shapes (if available and a bit harder)
e. g. :

download.geofabrik.de/index.html

Your lake AT5 data You can also lay over topo AT5.

So if I understand it correct, you better create maps in the vector format because of higher detail and resolution?

Hi Walleye,

In the context of Lowrance maps, the raster layer refers to the background graphic, which is coloured according to depth. The vector layer is the contours on top, and could also include the land areas, islands, points of interest etc.
To generate a map like the ones you see on this forum, you will typically combine both - so that you have a general idea of depth from the background colour, with the more precise/scalable vector contours overlaid on the top. It is easy to do this from RM, by exporting the background raster from the contour map view, and then exporting the contours as shapefiles which can then be processed by the Insight Map Creator.

Yes,

"the problem" is the zooming function of HDS and other Units.
Raster AT5 is much simpler to create, but if You want to keep good quality, You must create templates from different sight heighes in high quality (RM has at the current time one picture in screen quality). The creation of more complex raster templates is a bit expensive.

Vektor AT5 display the same content with 100 % quality in all zooming levels. But the creation is much harder. Still RM is the sole program, which create ready good templates for IMC or further processing.

Guys,

we need to be careful here. Vector graphics, while being supremely convenient, have serious drawbacks, particularly for the uninitiated. The accuracy of ANY chart depends solely upon the scale of the data from which the chart is derived.

If you make a vector chart with a shoreline based upon Google data where the size of a car was the size of a pinhead then by using that vector chart at levels of zoom (magnification) higher than the level at which it was drawn you are not getting any more accurate, its getting LESS accurate. In fact you are creating an ambiguity which is not going to be obvious to anyone other than the person who made the chart.

Raster charts are of such a nature that this kind of problem is immediately obvious.

So its horses for courses. Vector charts are NOT more accurate - they are just completely different. A vector chart is just as accurate as a raster chart at the same scale. If you want an accuarte chart then you need to do an accurate survey !
