Im a civil engineer and i try to measure 2 points with the same elevation and the accuracy when measuring was 0.61 and the result was not satisfying . The error between measures was 2.12 m in elevation . I may say its the best try for that kind of usage on mobile and it stands above all but I still can say that its not good at all about accuracy ... An answer by devs would have been good .
After a long time I found one of the excellent app and it has gave almost accurate reading.i compared survey done coordinate it was found less than 2meter error. Thank you very much who made this app.
This is really useful. Gives accuracy to half a metre quite quickly. Height not so accurate but overall its more than good enough for my proposed.
Co-ordinates were accurate. But, the elevation was wrong. Is it because my smartphone does not have barometer ? Does the application work fine even without barometer ?
This app is far more accurate than handheld gps i use,ive picked coordinates using both handheld gps & mobile topographer & ploted them in arcmap,its the best & most accurate app. as regards coordinates
not trying to be a critic but you can't get an accurate measurement on your phone for GPS data. just hope no ones really using this to topo a building
Good morning, I really like d app. But it just stop on my phone. Any time am try to launch it, it just display ACTIVATE SATTELITE RECEIVER (infinix hot5)
The app crashes in Mi6 pro.... This is very annoying... It is working for all other phones... please release a patch for it...
fantastic app, I used it for my dissertation work... it gave me 0.5m - 0.2m accuracy and perfect marking in ArcMap as well... GOOD GOING guys...just loved it...thank you...
Very nice. In addition, is there any way that I can customize coordinate system and add a geoidal model?
Very good application. I am just wondering: If I have callibrated against a known point, can I use "accurate positioning" to additionally improove the precision? Thanks
A Really nice app. Please make it possible to add more details (maybe unique identification) to the saved points.
A good app but need improvements. Its accuracy is bit less then other equipments I have tested it with
Its really a good app and is working perfectly compare to handheld GPS.. Kudos to developer.
Gnss, atleat one satellite is not appearing for me unable to pick the points. Please tell me if i want to change the settings
Good, but the accurate positioning in SURVEY option stopped working after the day two.
This app is good especially if you are travelling in the middle of the jungle
Is this is more useful to create a position of the Earth and using locating the land with co-ordinates of survey
Not good improve the quality non network area and it's display report also semple
Really good and a mandatory application for all surveyor
Very usefull as a backup for GPS.
GPS coordinates randomly stop updating, useless.
The height is not correct, there is written -18m msl but in my GPS Garmin 22 m msl
Satellite are not connecting speed
Any chance of adding altimeter/barometer readings to the application?
I can't believe the number of people who think their phone will give them survey grade data and complain when it doesn't. Buy a survey grade receiver! This app is awesome for a freebie! I would buy the Pro version in a second if it had geoid model and antenna height support.
