TopoFusion Pro / Backup of User Map Calibration Data?

« on: November 13, 2011, 04:42:38 PM »

Where are the calibration points of User Maps stored?

I accidentally clobbered the calibration of a User Map while trying to install a new map.

I then looked to see where the User Map was stored  in order to restore the old map and its calibration points from my backup files. However when I looked there, I only found the image file (JPG) but no calibration points.

Can you let me know where the calibration points are stored so that I can restore them.

Thanks,

TopoFusion Pro / Photofusion, No Time data in Tracks?

« on: August 27, 2010, 08:12:16 AM »

When attempting to run PHOTOFUSION, I get the message: "NO TIME DATA IN TRACKS". However when I list the track (GPX) file, I can see the time data. Also when I run the profile replay, I see speed data which clearly requires time data.

All help in finding the problem is appreciated.

Feature Requests / GMAP4

« on: January 06, 2010, 12:15:44 PM »

Today, on FreeGeographyTools.com, I found a reference to GMAP4 (www.mappingsupport.com/p/gmap4.html).

GMAP4 adds to Google maps by allowing downloads of USGS TOPO MAPS and Canadian TOPO maps from mytopo.com. The TOPO maps are superior to the TERRASERVER maps. I believe the TOPO maps are the  the TOPO maps that MAPTECH used to sell with MAPTECH NAVIGATOR.

 MYTOPO purchased the MAPTECH system from MAPTECH in the last year or so.

Apparently, MYTOPO is giving the maps away free, at least to GMAP4!

The maps ARE better than those on TERRASERVE. I recommend that TOPOFUSION look at the what MYTOPO is giving away and see if it can be included in the TOPOFUSION system.

TopoFusion Pro / Confusion concerning Climbing Analysis

« on: October 18, 2009, 05:47:45 AM »

I have some questions concerning the Climbing Analysis routine.

First, if the Presets is set to Straight Dem, what are the differences between the various DEM sources:
    -Use local Dem files, if available
    -Download/cache
    -Download/cache, force SRTM ?

I get significant differences in elevation gain depending on which source I choose. Is there a recommended choice?

Second, I understand that the first 3 selections of DEM interpolation methods are different mathematical interpolation techniques. However, what does the 4th technique, "From loaded tracks", imply?

Thanks for a great product,

Feature Requests / Ability to Load Google Maps and use Google Earth

« on: August 05, 2009, 12:08:39 PM »

I know this topic has been brought up previously.

But check out OZIEXPLORER. Their latest release permits you to use Google Earth  and Google Maps.
(I don't know why but the Google Maps view does not include the TERRAIN VIEW).

I presume they are doing something legal within the Google constraints on saving Google Earth files on a computer.

Check it out, it looks good.

Archived Support / How often to pick up trackpoints?

« on: December 02, 2006, 07:37:29 PM »

I have a couple of questions not about TOPOFUSION but about a topic you probably know a lot about..

    But first, the problem. I use a Magellan GPS most other people I know have Garmin GPS receivers.

    Typically when I hike with them , we get a difference of about 10% in the length of the hike.

    I have investigated the reason for the difference and believe I know what causes it. On my Magellan SPORTRAK, I pick up trackpoints every 0.01 miles. Looking at the trackpoints they are between 50 and 56 feet apart which makes sense. I looked at trackpoints picked up by a GARMIN recently and they were from 2 to 15 feet apart!

    The 0.01 mile setting on the Magellan is the lowest you can set. I am not sure how low the GARMIN receivers can be set. I do have the impression that GARMIN permits you to set the trackpoint frequency based on both distance and/or time.

    It is clear that the hike will be reported longer the more frequently trackpoints are picked up. The questions I have is:
    How often should track points be picked up to get reasonable accuracy?
    If you can answer that question, do you have a physical or mathematical basis for your answer?

    All info is appreciated.

Archived Support / GPX EDITOR?

« on: February 19, 2006, 09:12:21 AM »

Is there an easy way to edit a TOPOFUSION track saved as a *.GPX file?

 I needed to delete several trackpoints from a track. I found no way to do it in TOPOFUSION. I used GPSBABEL to convert the *.GPX file to an OZI  *.plt file. Using OZI, I deleted the bad trackpoints and then using GPS BABEL reconverted the*.plt file to a *.GPX file.

 It there a simpler way to do this? I would like to be able to select the trackpoints on the TOPOFUSION display and them directly delete them.

 All comments are appreciated.
