This is certainly possible. Create a new shapefile by choosing New under the menu Layers and there you select Shapefile. In the options dialog you choose Line and WGS84 projection and press Ok. It will prompt you to save somwhere. Now the newly created shapefile shows up in your layer list. Select it and toggle editing to on (the Pen icon on the toolbar, or ...

GPS is per definition always WGS84 EPSG:4326, so this should be ok. A most popular error ist to exchange lat and lon values, or forgetting negative signs for West and South degrees. And: Most GPS coordinates end up off the coast of Nigeria, because people have preset a projected coordinate system like EPSG:3857 for the project, not considering that the GPS ...

Use the Points to Line tool. http://resources.arcgis.com/en/help/main/10.1/index.html#//00170000003s000000 You could use a datestamp for the sort field, if the default doesn't work the first time. The shape length of the line should be included in the output feature class, if it is in a geodatabase. You might want to check the length by adding a field to ...

PPP relies on post-processing using precise orbit and clock data from the satellites. This is data for the same timespan as your measurements, and is based on logged information from reference stations. If you require on-the-fly positioning I doubt you can use PPP.* Depending on your location there may be correction services available where you instead of ...

Did you edit the data in that table at all? It's strange how there is one row with its lat/longs in DDMMSS when all the others (the ones that aren't blank) are in decimal degrees. Also, do the points which are missing positional data actually show up in ArcMap? Are they where they're supposed to be? As far as the missing data, it looks like everything went ...

If it is a garmin gps you can use an android phone/tablet plus the app Garmin Exchanger to put move waypoints and tracks to and from your gps unit. You will also need an android otg cable and your gps usb cable. It works pretty good. I use a garmin everyday for work and I use that app to email and receive data that I need to use for my gps.

I made a simmilar application a few time ago. I registered my cellphone position, sending a CSV each 5 minutes, and inserting it in a postGIS database. To sum up: Load csv in PostGIS database. I made it with shell script in the server, run each 5 minutes, and update the table. Filter the results on the database. Once in postgis, you can export it to a ...

Just use a Spatial Join. You can do this with QGIS (free to download; you may already be using it). Here is a tutorial that does exactly what you are trying to do using nursing homes as points (you'd use your GPS locations instead) and boroughs as polygons (you'd use Counties). Tutorial

Any given GPS unit only has a certain level of accuracy, and different units will determine their position in different ways. The technical term is dilution of precision (DOP) and there are many contributions to the error: what satellites are providing the signals, what time of day is it, is it cloudy, are you near dense vegetation, is the signal bouncing ...

I used Michael Miles-Stimson answer and converted it to a line (points to line), then i just used the measurement tool and clicked on feature and it calculated it. thanks

Do you mean something similar to a CORS network? If so IGS has a few stations in India: http://igscb.jpl.nasa.gov/network/complete.html I am looking for GNSS receivers active in India as well, hopefully a more dense network of receivers. If anyone knows of such a service please respond. I would guess that there are GAGAN stations with some information ...

Mobile Mapper 120 (around 4000$ with Glonass Option) And a Trimble Geo XT (around 8000$ glonass option) We use it to do forest inventory, the goal is to send people where we want them to go and not let them choose an area where there is less trees to count (because garmin or other old gps without glonass were not as precise and they had a distance flaws). ...
