Some of the tools can be used on either Mac or PC įor example, Text Editor and GPS Visualizer (browser-based). The objective of this Help article is to provide options for ways to obtain the data needed for a hike description for the Albuquerque Senior Centers’ Hiking Groups (ASCHG) website. How much money you are willing to spend on mapping or image editing software.gpx files with a text editor or using new software programs. Which tools you choose to use will depend on several factors: Software programs that modify image output from mapping software to meet image requirements for the website (IrfanView and Google Photos, among others).Software programs that create and export displays of GPS data on topographic maps (mapping software) (GPS Visualizer, NG TOPO, DeLorme North America, and Garmin BaseCamp).Software programs that interface between the GPS and the computer and/or perform simple transformations of data (EasyGPS and GPSBabel).The five primary categories of tools for working with GPS data are: Default Toolbar Symbols and Their Meaning.Determine Total Uphill / Total Downhill. Determine Maximum and Minimum Elevations.National Geographic TOPO! ® New Mexico (PC).Draw Tracks and Waypoints on a Topo Map.Draw an Elevation Profile and Determine Maximum and Minimum Elevations.The final product still has a few glitches which are mainly due to me being a bit slow to switch on data roaming or because Latitude failed (I believe there are a few days in 2012 where this was the case for my account). $GPSBABEL -i gpx -f $1 -x transform,wpt=trk,del -x transform,trk=wpt,del -x simplify,count=7500 -o gpx -F simple.gpx $GPSBABEL -i gpx -f $1 -x transform,wpt=trk,del -x transform,trk=wpt,del -x simplify,count=7500 -x transform,trk=wpt,del -o kml,lines=1,points=1,line_width=4,trackdirection=1,labels=1 -F simple.kml It is a good idea to reduce the number of points a little bit which is easily achieved with gpsbabel. I could finally look at the result in Google Earth. Gpsbabel -t -i gpx -f $file -i gpx -f join.gpx -x track,merge,title='2012' -o gpx -F join-tmp.gpx # first gpx file and then deleted all track points. # actually this needs to be file that has valid GPX but no points $GPSBABEL -i gpx -f $file -x transform,wpt=trk,del -x radius,distance=0.2K,lat=$LAT,lon=$LON,nosort,exclude -x radius,distance=0.2K,lat=$LAT0,lon=$LON0,nosort,exclude -x transform,trk=wpt,del -o gpx -F tmp.gpxĪ few days (or weeks) later I had cleaned the entire data set and glued the traces back together with gpsbabel. So, another was used to scrub out those points. I soon noticed that Latitude keeps reporting the same wrong data. split/$begindate.gpxįinally, I could go through every day and delete points that were wrong. latitude-ordered.gpx -x transform,trk=wpt,del -x track,split,start=$begindate,stop=$enddate -o gpx -F. I used gpsbabel to break down the data into days.īegindate=`date -d '$FirstDay +$(( $ +1 ))days' +%Y%m%d`00Įcho '$day $begindate $enddate' Now, the problem was that the entire annual data was a bit large. Again, it took a while to find the right program that I liked, eventually I found gpsprune. So, the next step was to find a program that allows to edit a gpx trace. Unfortunately, Latitude includes quite a bit of erroneous data. At last I could see my track in Google Earth. The first disappointment was that the takeout data was in json format and looking at it was not easy … After searching around for a while I found this script that converted json to kml. So, I downloaded my data and thought I would quickly make a little map. This however looked like it would make the whole project much simpler. I had previously wondered how I could display my annual travel and had dabbled with the possibility to download parts of my entire in kml format form within Latitude. Just before Christmas 2012 a friend pointed me to Google Takeout that allows to download all data Goggle has stored about you including the Latitude data, if you have signed up for it. This worked slightly better with more advanced phones, but until I got my hands on a Nexus S in Autumn 2010 this always stayed very patchy. Soon after Google Latitude started I signed up for it and sporadically updated my location. I wrote this a a few years ago for my website that I have now migrated to wordpress.
