Basemap Arcgis and GPS point

[RafaAlcala]

Hi, I am working online with the basemap of Arcgis at world imagery. I am working in at small area of York. I took some gps point with a garmin etrex with position frmt: UTM/UPS, map datum: WGS84, units: meters, like the basemap. I would like to pass this mark to Arcgis but when I have done, no point it is put properly. Could you help me with this, please?

Try running the data through a proper GPS convertor such as GPSBabel.

You might also want to look at alternative basemaps. How about converting the points to British National Grid and using OS Streetview?

I do not have the cable to download the gps data (garmin etrex H) to the pc

I need and aerial photograph of my place with high resolution. Is it free to access this information to ordnance survey?

Yes it is part of OS opendata products. However it's not aerial imagery.

The set up is
Position Frmt: UTM/UPS
Map Datum: WGS84
Unit: Metric
North ref: Grid
Variance: 0,02 E
Angle: Degrees

I attached to you a file.txt with some point

You said that UTM 30N coords York are the same value that I will find in France using the WGS 84 Web Mercator (Aux sphere) coordinate system. However when I introduce my value (gps point) in googe earth, there are location in York not in France. This is why I am too bewildered. Thanks you for your help

Also i just looked at this data. The x coordinates have 6 characters and the y coordinates have 7. Is this right? Shouldn't they both be 6?

The x coordinates start with 06.... but zero number disappear when I write the number. This is the reason to have only 6 characters

I think Google Earth is correctly identifying the data as UTM coordinates. However, when people mash up data with web services, the tiles are natively in "web Mercator", so it's faster to project other data layers to that coordinate system.

ArcMap has the complication that the Add XY Data tool will default to the data frame's coordinate system--which you have set to web Mercator. So ArcMap thinks that these UTM coordinates are really in Web Mercator. What happens if you change the coordinate system to WGS 1984 UTM 30N for this data?

If you're going to use British National Grid coordinates, you'll also need to set a geographic/datum transformation in ArcMap between OSGB 1936 and WGS 1984. (Data frame properties, coordinate system tab, transformations button)
