The only time a simple linear rectification with 2 control points will work properly is if the rectification is done in the same projection that the map was...
... I can suggest memory map http://www.memory-map.co.uk/ Some versions support Raster import. I have the european edition, and I can load any map created with...
Mike, That makes sense. If I were to first export the base map (of the world) while in Mercator then start over by first loading this, followed by rectifying...
Conor, That wouldn't really help as it is the native projection of the map being rectified that is the issue. The other maps projection won't matter as Global...
Mike, I think there is a clarification needed, my apologies if that is not so. The goal is to place the smaller map on top of the larger map and of course in...
Conor, If the small map is indeed in Mercator then a linear stretch should work. Are you adding the control points to the small map in Mercator? Perhaps you...
Mike I uploaded a zip file (reference image for freightgateUSA.zip). I adjusted the transparency to highlight the difference between layers. Conor ... From:...
Sir I have a garmin gpsmap76cx handheld and you can load on your on maps to this unit.It also comes with an sd card in the unit of 180 MB micro.You can buy...
Hi Jack, Well Garmin said you can't. It needs to be (like Magellan) in one of their formatted software applications and those applications do not allow you to...
Lewis To make myself clear you first have to convert your map to the Garmin format .img file.There are groups out there that can explain how to do this.Garmin...
Conor, I was finally able to download the file and take a look. The problem is that you are rectifying the TIF file as Geographic (lat/lon) when it should be ...
Mike, That does indeed work. Thanks So, for the future, is it usually a good idea (or possibly the right thing) to make sure that the projection of the image...
Conor, Yes, if you know the projection of the map being rectified then you should rectify in that projection. If you enter a lat/lon value Global Mapper will ...
Folks, I downloaded some 2007 NY East ortho imagery from USGS Seamless this morning from the Long Island area. When I import the images into GM (v.9.3) the...
What is likely happening is that the projection code in the GeoTIFF file is being incorrectly interpreted as being feet when it is meters. There was a problem...
I a beginner in global mapper and how can i arrange the maps for printing with legend, title, north arrow. can we create the legend of thematic maps...
Currently the best way to do this is to use the File->Open Data File at Fixed Screen Location menu option to load graphics that you have created at the...
Hi Mike, Want to use Cº (degrees Celsius ) as custom elevation units display. The degree symbol (ALT+0186) shows up just fine in the definition box but shows...
Mike, I saved a BigTIFF of about 8 GB without any problem. I use GM10 from April 4, 2009 When loading this TIFF GM reports: Error opening TIFF file: Path ...
Greina, Is it possible that some other application has the TIFF file open or something? Can you make a copy of the file and try opening that to see if it has...
Hi, I am new to global mapper, and I am still trying to get a feel for the capabilities. I bought the software mostly for the KML super-tile generation ...
Hugo, You can do this in Global Mapper with a bit of work. You'll first need to setup the options for each layer in the Control Center to use your July ...
Mike, I restarted the PC, copied the file but the problem was the same. I have no idea what the problem is, which I was able to reproduce several times. If you...
Greina, If your connection is fast, is it possible for you to FTP the bad file to ftp.globalmapper.com using a username of 'upload' and a password of 'upload'?...
Mike, Yes, the two the gridded files are also BigTIFFs. All files are 24bit RGB LZW, just ordinary maps. Upload would take a week. Perhaps you know a tool to...
Greina, The only tool that I know of to check BigTIFF files is Global Mapper itself, I'm not aware of any other applications that support it yet. It wouldn't ...
