capture large maps from google maps

Google Maps is a great place to find vastly detailed street maps. But it is basically an online tool and Google doesn’t offer a way to save a map.

you need firefox and this add ons
https://addons.mozilla.org/en-US/firefox/addon/screengrab/

Tools Required:
  • Firefox Browser.
  • ScreenGrab extension for Firefox : It will capture what you can see in the window, the entire page, just a selection, a particular frame… basically it saves webpages as images – either to a file, or to the clipboard.
  • Notepad.
Let’s Start:
1.  Open up Firefox and install the Screengrab extension.
2.  Go to http://maps.google.com/ and open a map of the location you want.
3.  Zoom to a level that would be right for whatever purpose you are finally going to use the map for. Just don’t bother about the size of the map now. We will deal with that later.
4.  On the top right hand side of the map you would find a link called…..’Link’. Click on it. In the little pop-up that appears, click on ‘Customize and preview embedded map’.
googlemap_link
5.  A new pop-up window opens up where you can customize the size of the map. Select the ‘Custom’ option and enter the width and height (in pixels) that you want your final map to be. For example, you could change the values to 5000×4000. The preview map will change to reflect the new size.
googlemap_customsize
6.  Once you are satisfied with the size of the map, copy the html code that appears below the preview map.
googlemap_htmlcode
7.  Open Notepad and paste the above code. Name the file anything you want but make sure you save it with the extension .html. For example, you can call the file mymap.html.
(Tip: In the Save dialog box enter the name as “mymap.html” including the quotes to force Notepad to save the file with the extension .html and not .txt)
8.  Open the html file you created in step 7 in Firefox. You would see your map displayed in the same size you selected in step 5. Of course, much of the map would probably be beyond the screen and you may have to scroll horizontally and vertically to view the hidden area.
9.  Now that we have the map of our desired size, all we need to do now is to capture and save the map as an image file. Here is where the ScreenGrab extension for Firefox comes in handy. Assuming that you have already installed ScreenGrab, you would find the ScreenGrab icon at the bottom right corner of Firefox. Click on the icon and choose Save>Complete Page/Frame. After a moment, a save dialog appears. Save the image as a PNG or JPG file.
googlemap_screengrab
That’s it. Your large size map is ready.
The above trick can be most useful for grabbing maps for use with your GPS enabled mobile phones . Of course, you would need to calibrate the image file before use with the GPS device.

WHAT IS THE DIFFERENCE BETWEEN A SUB-DOMAIN, PARKED DOMAIN AND AN ADD-ON DOMAIN?

We get asked this question all the time. The answer is actually pretty straightforward:Sub domain
  • Lets say your domain is mysite.com.
  • You install a Message Board and put in in a directory called mysite.com/board/.
  • You can turn the directory board into a sub-domain by adding it as a sub-domain from your Control Panel.
  • Now you can access your Message board as either  mysite.com/board OR board.mysite.com
  • This costs you nothing and is free.
Parked Domain
  • You have two domains mysite.com and my-other-site.com.
  • mysite.com is the domain of your website and you want to add my-other-site.com.
  • You want them both to go to the same place. In other words, when someone types either www.mysite.comor www.my-other-site.com they will go to the same page(s) on your website.
  • In order to have additional parked domains you need to purchase them from a registry.
  • Register Parked domains here (open a new account if you don't have one registered)
Add-On Domains
  • You have two domains mysite.com and my-other-site.com.
  • You want the two domains to be totally separate/independent websites.
  • In order to have additional add-on domains you need to purchase them from a registry.
  • Register Add-on domains here (open a new account if you don't have one registered)

OK SO WHAT MUST I DO TO MAKE IT ALL HAPPEN?
Procedure - Parked and Add-On Domains (THE ORDER IS IMPORTANT)
  1. Register the domain. (If you do not have an account here, you need to create a new account. This is notthe same as your webnet77 account -- you will receive a new username and password from the registry. Keep it safe).
     
  2. Make sure the Name Servers at the Registrar point to our DNS. - when ordering a new domain make sure the "use Webnet77 nameservers" or "use default nameservers" is checked. To set the DNS manually, check your original welcome email (near the top) for the DNS settings. 
     
  3. Add the domain only once from your Control Panel as either a Parked or Add-On Domain by locating the Add-on or parked domains link in your control panel. (Trying to add it more than once can break things on your website).


  • TIP: if you add a domain as a parked domain (or as an add-on) and change your mind and want to change it to the other flavor, simply login to your Control Panel and then locate whichever of add-on or parked domains it currently is and delete it. Once the domain has been deleted, you can safely add it back as the "other" one.
     
  • TIP: When you add an add-on domain, use the domain name as the folder name. This will be the folder it creates on the server for the "root" directory for this domain. Having it the same as the domain name makes it easy to identify if you have many folders.
     
  • TIP: To FTP directly to your new add-on domain, the
     
  • IMPORTANT: When adding add-on domains use a decent password. (Use the password strength meter to make sure it's 80% or higher)
Procedure - SUB-DOMAINS
  1. You can add a sub-domain whenever you like and there is nothing you need to register at the registry.
     
  2. Add the sub-domain(s) only once from your Control Panel.

Email Tracking- How to track the original location of an email via its IP address

Here’s a quick how-to guide on how you can track email to it’s originating locationby figuring out the email’s IP address and looking it up.
