I've tried adding layers with the details only on the 0 layer with just gross detail at the next layer - still get the hounds tooth.
I've tried increasing the TRE_SIZE, nothing changes. I can take the data that I'm using for the example above and select a smaller region and get a good map. I can make a simple map of the same extent and not get the hounds tooth. I've been doing a lot more experimentation and the issue seems to be the complexity of the map. Transparent = S didn't make a difference. I suspect these are newbie errors that are familiar to the more practiced, but I'm baffled. I've been careful to delete all my intermediate files (rename outputs) so I know I'm seeing the results of my new run. typ file, etc, and keep getting this nonsense. I've tried this process numerous times, tweaking zooms, changing type, use of external. What are these? They appear to be some sort of simplification of the curves, but why are they there? They seem to relate to my zoom levels, but how?Īnd the final kicker - when I zoom out, I get this: Here's the corresponding region in MapSource - notice the extra straight lines. Here are the various settings:Īnd here's what a small piece of the map looks like in GPSMapEdit I add another level (otherwise I get an error that about generating the preview). All the roads are imported as type 0x000a (unpaved) at level 0. I backed up and created what I thought as a simple map, importing a shapefile of roads into GPSMapEdit. typ file to control how the lines look, you could make them a very light grey so they don't stick out too much.I thought I was beginning to understand this stuff, but now the mysteries are multiplying.
typ file).ģ) There aren't any transparent polygons in the traditional sense, best way would be to use polylines to make a grid, again you could use a. So you could use feature point type 0圆417 (manmade place, other) for the railroad station, and customzie the icon that's displayed for that type with a. typ file with your maps you can change how points, polylines, and polygons appear for the map. I don't know if the HCx has that option or not, if so it could be turned off.Ģ) If you use a. I should appreciate any observations or advice.ġ) Some Garmin units have an option to display urban areas or not. I should like to have the facility to load a grid or graticule for referencing and identification purposes (this would be an outlined transparent polygon file, with a grid reference attribute for each square). I should have thought that would be an important feature so far as locating in GIS is concerned.ģ. I am surprised that there is no symbol for a railway (railroad) station. I should have thought urban areas would have worked in the same way.Ģ. Neither of the two urban area polygon styles I have tried display at all in my Garmin, yet something like City parks displays perfectly, with any line or point features appearing on top. I have been applying them to vector mapping data that I eventually load into my Garmin Legend HCx via cGPSmapper and Img2gps very successfully.ġ.
I am extremely impressed with the choice of lines, points and polygons avaialble for use in GPSMapEdit.
