Google Earth vs Google Maps

 

Good day to all members,

Could you kindly tell me do I obvioulsly need to install Google Earth to find coordinates for building my POIs files?

Most of the time, I use Google Maps with the right-click on the place what I want their coordinates.

Google Earth is more, same or less accurate than Google Maps?

What kind of infos you can get more with Google Earth in lieu of Google Maps?

Many thanks to shade the light on it.
Nice week-end to all

Google Earth is either

Google Earth is either useful or necessary, depending on whether you're part of the Google Maps beta test or not. If you're not part of the open beta, and you don't appear to be using the beta, then you already know how to get coordinates in Google Maps. Otherwise, you can use Google Earth's pushpin feature to get coordinates. To do this in Google Earth, go into Google Earth's options and change the "Show Lat/Long" function to Decimal Degrees. Then press the pushpin button at the top of the screen. When the pushpin appears you can drag to wherever the POI is, and the coordinates will change.

Accuracy is generally the same regardless of which you use. Since Google Earth links to the Internet to get its information, the amount of information the two provide should be equal.

use itouchmap

Use http://www.itouchmap.com/latlong.html. It's much more user friendly in my estimation.

Itouchmap

That certainly is worth a try.

You said building my POIs files

This implies to me that you know the addresses of the places you wish to include in a POI file. Assuming that this is correct, then you may want to look at Extra POI Editor (EPE) written by one of our members - TurboCC.

For information see
http://www.poi-factory.com/node/38068
http://www.poi-factory.com/node/33782

The main reason I would suggest EPE is that it can do geocoding in the process of directly creating POI files. It is very easy to adjust coordinates such that they fall within roughly 100 feet of the centerline of the "route" (so that you can get "alerts").

The basic steps would be to
1. open EPE
2. click the magenta colored "Add New POI" button in the upper left pane (of 4 panes).
3. enter as much of the address as you know
4. click the "Geocoding" button at the bottom of the upper right dialog box.
5. Zoom in to verify that the marker is within roughly 100 feet of the "route" (I like to use the "Hybrid" view).
6. Drag the marker as necessary
7. Click the "Grab" button at the top of the screen to acquire the coordinates
8. enter a name for this POI
9. Click "Ok" at the bottom of the dialog to create a POI entry
10. repeat for the other locations.

As you can see, the address typing is not any different than you would do in either Earth or Maps. However, you wind up with a formatted POI file without, say, cut and paste actions. Plus, if you want to include other information, fields are available to do so.

You can save the POI file as .csv or .gpx as desired

Thanks to your answer,

Thanks to your answer, jgermann
Yes, I already install EPE but haven't time to play with it. I'll try it this week-end. I always use word/wordpad or excel to create my POIs files. Time to give EPE a try.

After reading the POIS Factory tutorial section, it's still not clear in my head WHY I should use Google Earth when I can find the coords with Google Maps. hence, I open this thread in hope you can shade the light on these two apps. Thx again.
Also thanks to people who gave their comments about it.

While I rely on EPE for my POI files I find it very cumbersome for doing more than one or two locations. I have Excel files I use as source files that are inputs to EPE. My file creation time for a file with many locations such as the Five Guys file is about 1/8 the time of trying to do EPE one location at a time.

I build an Excel file with the various elements in separate cells then tell EPE what is in each cell. Having EPE read the file, ignoring missing elements such as lat/lon and then telling EPE to geocode is much faster. There are always a few locations that do not resolve correctly and fixing those is much faster than typing in the various elements and then geocoding them singularly. But then I'm also adept at using Excel and manipulating text strings.

Google Earth

I still use Mapsource when building my files and I use the menu item View / View in Google Earth to help fine tune the location of my POI. Going back and forth between the two I can adjust the location of the POI so I "drive through", or at least come very close to the POI's location so the unit stops navigating on its own.

You may want to use Google Earth to make the file and EPE to covert to GPS or csv. See (link no longer available)

Combining techniques

Charlie has given you a link to a way to use Google Earth and EPE to create a POI file that would be well used when you are investigating, say, some destinations for a vacation, say historical sites, amusement parks, etc. Earth/Maps will locate such sites for you as waypoints.

I indicated a way to take addresses you already have and use EPE to geocode them. I was making an assumption that you did not already have the addresses in machine readable format.

BoxCar tells us of how he takes a machine readable file containing addresses and uses EPE to "batch geocode" the entire file.

So, let do an exercise to see how that would work. Consider the following file:

Quote:

,,"Washington Monument","2 15th St NW, Washington, DC"

,,"White House","1600 Pennsylvania Avenue Northwest, Washington, DC 20500"

,,"Smithsonian Institution","1000 Jefferson Drive Southwest, Washington, DC 20004"

,,"Botanical Gardens","100 Maryland Avenue Southwest, Washington, DC 20024"

The above file came from a four (4) line file created in Notepad (blank lines were added for readability)

If you were to cut and paste the lines within the quote into Notepad and then delete characters until you have 4 and only 4 lines - each starting with two quotes - and then save that file by
File > Save as > "Washcutpaste.csv" into some folder (the quotes surrounding this name are important as they instruct Notepad to save the name AND extension) - then you will have a file to use in EPE.

Fire up EPE and "Open" Washcutpaste.csv.

EPE will give you a message that
"POI on line 1 does not contain valid longitude and/or latitude"

Check the "Apply to entire file" box and then "Ignore"
so that EPE will read the file.

Now, do Tools > Batch Geocoding (or press F5) and allow EPE to do its work.

When EPE returns, look at the result and you have a file you can use.

...

On the bottom of Google Maps, you will find Maps Labs with tools you may find useful.

Better accuracy

I use the Notepad/Google Earth technique all the time to create a .txt file, then use EPE to add things like proximity values and convert the .txt to .gpx.

I like GE for two reasons. The first is because a destination's address isn't necessarily indicative of where you want to go. Example: what's the address of a covered bridge out in the middle of nowhere?

The second reason I use GE is so that I can fine tune the lat/long to point exactly (well, accurate to 6 decimal places accurate) to where I want. Example: I use the pushpin to mark the driveway, parking entrance, etc. of my destination.

Hi jgermann, EPE lets me have 3 .csv files choices for saving file.
The best choice is GARMIN csv file saving?
Thx

Google Earth KML

One thing that Google Earth does very well is process many features of KML. Google Maps does not support all the attributes so it is difficult to do many interesting things with Google Maps. I just completed a small side project to track aircraft transponder propagation and it would not have been possible without Google Earth and KML. Loading my generated KML into Google Maps does not render properly but works great in Google Earth. There have been rumors that the next release of Google Maps will support layers and other features currently lacking. Of course there is always the Google Earth plugin.

About EPE, in the Google Earth page, what is the utility of the big blue circle and two green smaller circles inside it. And how to display them?

Thanks and have a good sunday every one.

The blue circle shows the alert distance.
