Modifying the parameters a bit (Figure 2), more detail is visible for some features, but other features disappear completely, and color changes are still an issue. (Figure 1, a screenshot from a Garmin 60Cx GPSr). Initial results with BMap2MP’s default configuration settings weren’t promising – much of the map detail is lost, contour lines are irregular and broken, and feature colors change depending on whether they’re on the green or white background. Moagu automatically tiles large maps into smaller submaps to get around this issue. For maps with less detail, you could probably use larger images for maps with lots of small details, or aerial photos, the maximum size is likely to be smaller. For the USGS topo map for my area, which contains a fair amount of topographic relief but minimal road/house detail, the largest image I could process at the native map resolution (2.4 meters/pixel) was about 2000 x 2000 pixels, or roughly 1/4 of the entire topo quad. The maximum size of the image that you can process depends on the amount of detail in the image. map geocalibration file created by the GPS utility program OziExplorer ($95). Raster imagery needs to be in BMP format, and have a accompanying.

You’ll also need to know how to use cgpsmapper, which is also a command-line program. But you should probably be at least somewhat familiar with some of the terms and processes involved in creating custom Garmin map files before tackling the read-me, since it assumes at least a basic knowledge of creating maps with custom TYP files.
There’s a long list of adjustable parameters, most of which are described in an accompanying read-me file, to varying degrees of detail. BMap2MP is a command-line program, with program parameters set in an associated configuration text file.

rar format if your compression program can’t handle that format, try 7-Zip. I’ve spend some time playing with this program, and comparing its results with comparable maps from Moagu.īMap2MP comes compressed in. img map files using the free or paid versions of cgpsmapper. This code can then be compiled into Garmin.

There’s a commercial software package called Mapwel that can do this, but I’ve recently been made aware of a freeware program called BMap2MP that also converts raster images into vector polygons, and creates map code for those polygons in the. While this approach can speed up display time dramatically, it can also be harder to get good results. An alternative approach is to convert a raster image into many small vector polygons, then code those vector polygons as a Garmin-format map. Moagu creates a true bitmap image for Garmin units, with advantages (accurate map and photo reproduction) and disadvantages (slow display times). I’ve posted previously about Moagu, my utility that converts raster map imagery into raster-format maps for some Garmin GPS units.
