The black edges come from re-projecting the map to a different coordinate system, and there's currently no way to get rid of them in G-Raster. You would need to combine the GeoTiffs in a different program. Suggestions: 1. Global Mapper - Fantastic program, but expensive ($300). 2. TatukGIS Viewer - Free, although it does stick a watermark on the bottom of the output image. You'd need to load in all the images, then export them as a TIFF with a worldfile. You'd then need to open that image in G-Raster as an image with worldfile, then specify the coordinate system (UTM, whatever).

I suspect the two different TYP files for the two different kinds of maps are "fighting it out", and whichever one wins determines which map gets displayed. Moagu maps use a custom TYP file, and if those types aren't defined, you'll get a blank area. If they are defined correctly, then they may be overriding the TYP definitions in the other file, though they shouldn't have to - the Moagu TYP definitions use hex specifications that are well outside the normally used point sets. If you send me a copy of your original text TYP file, I could probably figure it out (feedback at moagu.com) You might give MapSet ToolKit a try in installing these maps into MapSource; there's a step-by-step in the latest help file. MapSet Toolkit makes it easy, it does all the complicated work, including the registry installation. Or, combine the .img and .TYP files into single files with SendMap, and then upload those using MapUpload instead of SendMap or img2gps.

If it's taking several minutes to render the map, you're almost certainly viewing it with Map Detail set to More or Most; doing so will load in data at a higher resolution than that required by the Zoom level. With Map Detail set to Normal, so that the right data loads in for a zoom level, the longest a topo map image should take to load is about 20-25 seconds, and usually faster than that. Even a black-and-white or color aerial image takes less than a minute to render, and they have far more data to display than a topo. Several minutes to display the map is way to long, I've heard people say the delorme PN-20 has slow redraws but their claims of 5 second redraws don't seem so bad now. If I want good maps I'll just save the money and not buy Moagu, put that money toward the Pn-20.

In terms of load time and highest resolution, this can't compete with the deLorme PN-20, certainly for aerial imagery, and even for topo imagery. I will say that once the aerial imagery is loaded, the display will keep up with your position at low speeds; definitely for walking speeds, and even slow biking speeds (up to about 12 mph according to one report I've gotten). So if you can set it at one zoom level and leave it there, it'll do the job; if not, you do need to look elsewhere. This is really intended for those who have a Garmin already, and don't want to cough up $650 bucks for the PN-20/XMap bundle, or buy a PN-20 for $400 bucks and pay for downloaded areas by the square km. Not to mention the PN-20's smaller screen and poorer sensitivity. For $20, it's not a bad deal.

Those are some nice screenshots. The finest minds on the planet (not including me) are looking at why Moagu maps won't work on the Colorado, and hopefully will find a solution soon. Might I point out some advantages of Moagu over MapWel for creating raster images? Some of this is taken from the review of MapWel's rasterization functions at http://travelbygps.com/articles/cartography.php. - MapWel requires a map to be scanned at high-resolutions (0.5 meters per pixel) for good results; Moagu can create a map from any scanned resolution, like the 2.4 meter per pixel topo maps from the USGS I was wrong about this, it actually works better with lesser scan resolutions; I misunderstood. - MapWel won't necessarily work well for areas greater than 1 km x 1 km, with possible rendering/display time issues as you go to larger sizes; Moagu has no such limits. I've created one map 20 km x 20 km on a side. - MapWel gets its best results for 8-10 colors, and has a maximum of 16 colors currently supported (and only 60 maximum possible); Moagu supports 254 colors, the maximum on older units (60C series, 76C series). The Colorado maps shown with sharply drawn lines are vector maps drawn on top of a reduced-color vectorized raster image. - Moagu is also a lot cheaper; $29.95 ($19.95 before 4/30) gets you a copy with no limitations on map distribution. MapWel costs $45 for a version that limits you to one GPS unit, and $90 for an unlimited version. Don't get me wrong - MapWel's a great program, especially for vector maps, and its vectorized rasters might be better for certain kinds of imagery (sharp divisions between areas, small range of colors). But I don't think it could make a raster image comparable to this one created by Moagu: Moagu has a free demo mode that lets you create single tiles; give it a shot! http://moagu.com
