| 00:01 | Welcome to this tutorial on Creating Dataset using Google Earth Pro. |
| 00:07 | In this tutorial, we will learn to |
| 00:10 | Download and Install Google Earth Pro. |
| 00:13 | Use Google Earth Pro to navigate and create a dataset. |
| 00:19 | Create point and polygon files in Kml format using Google Earth Pro. |
| 00:26 | Open Kml files in QGIS. |
| 00:30 | To record this tutorial, I am using
Ubuntu Linux OS version 16.04 |
| 00:38 | QGIS version 2.18 |
| 00:42 | Google-Earth Pro version 7.3 |
| 00:46 | Mozilla Firefox browser version 54.0 and |
| 00:50 | A working Internet connection |
| 00:55 | To follow this tutorial you should be familiar with QGIS interface. |
| 01:01 | For pre-requisite QGIS tutorials, please visit this website. |
| 01:07 | Google Earth is a computer program that renders a 3D representation of Earth. |
| 01:15 | The program maps the Earth by superimposing, satellite images, aerial photography, and GIS data. |
| 01:25 | The program allows users to see cities and landscapes from various angles. |
| 01:32 | Let us download and install Google Earth Pro. |
| 01:37 | You can skip this step if the program is already installed on your system. |
| 01:42 | Open Google Search page. |
| 01:46 | In the search bar type “ Download Google Earth Pro” and press Enter. |
| 01:53 | A page opens with results. |
| 01:56 | Click on the first result, Earth Versions-Google Earth. |

| 03:23 | Close the terminal. |
| 03:26 | Open the Dashboard and type Google Earth Pro in the search box. |
| 03:32 | Click on the Google Earth Pro icon.
This will open the Google Earth Pro interface. |
| 03:40 | The steps to install Google Earth Pro in Windows and Mac is given in the Additional material. |
| 03:48 | Read the Start-up Tips page. |
| 03:52 | Click on Close button to close the window. |
| 03:56 | Now we will create a data set using Google Earth. |
| 04:00 | In the left panel, under Places tab, right-click on the Temporary Places folder. |
| 04:07 | Select Add and then select Folder from the sub-menu. |
| 04:12 | Google Earth - New Folder dialog-box opens. |
| 04:17 | In the Name field type Places in Maharashtra. |

Show contents as options. |
| 04:31 | Click on OK button at the bottom right corner. |
| 04:35 | Places in Maharashtra folder is added in the Places panel. |
| 04:40 | Now we will create a point data set in this folder. |
| 04:45 | We will use Google Earth to navigate to the location. |
| 04:50 | In the search box in the left panel, type Mumbai.
Click on Search button. |
| 05:00 | The Google Earth will zoom the map to locate Mumbai area. |
| 05:05 | The location of Mumbai is shown. |
| 05:10 | Click on Add placemark tool shown as yellow coloured pin on the toolbar. |
| 05:17 | Google-Earth New Placemark dialog-box opens. |
| 05:22 | In the Name field type Mumbai. |
| 05:26 | Click on the Pin icon next to the Name field. |
| 05:31 | Icon box opens with options to choose.
I will select red pin icon. |
| 05:39 | Click on OK button at the bottom right-corner in the Icon dialog-box. |
| 05:46 | Click on OK button on the New placemark dialog-box. |
| 05:51 | Notice that a new placemark is added on the map. |
| 05:56 | Mumbai location is added in the Places panel. |
| 06:01 | Clear the search result in the search panel.
Type Pune in the search box. |
| 06:09 | Select Pune Maharashtra from the search options.
Click on the Search button. |
| 06:17 | Google Earth will zoom the map to locate Pune city. |
| 06:22 | The location of Pune is seen on the map.
We will add a Placemark for Pune. |
| 06:31 | Click on Add placemark in the toolbar. |
| 06:35 | Follow the same steps we did earlier to placemark Mumbai . |
| 06:43 | After completing all the steps, notice that a placemark is added for Pune. |
| 06:50 | Follow the same method and mark a few more cities: Satara, Nashik, Amravati, Chandrapur, Jalna, Latur, and Dhule. |
| 07:05 | We have created a location map for a few locations in Maharashtra. |
| 07:11 | Now we will create a boundary layer for these locations. |
| 07:16 | Right click on Places in Maharashtra folder icon. |
| 07:20 | Click on the Add option.
Select Folder from the sub-menus. |
| 07:28 | Google Earth New Folder dialog-box opens. |
| 07:33 | In the Name field type Boundary. |

| 07:54 | Drag the slider till we see the Maharashtra boundary. |
| 07:59 | Click on the Add polygon option from the toolbar. |
| 08:04 | In the Name field type Boundary. |
| 08:08 | Start clicking on the boundary of Maharashtra and roughly draw Maharashtra boundary. |
| 08:31 | Once finished click on OK button in the box. |
| 08:36 | Boundary polygon layer is added in the Places panel. |
| 08:41 | Right click on the folder Places in Maharashtra. |
| 08:46 | Click on Save Place as... from the sub-menus. |
| 08:51 | Save file dialog-box opens. |
| 08:55 | Let us name the file as
Places in Maharashtra. |
| 09:00 | Select a suitable location to save the file.
I will choose Desktop. |
| 09:07 | You can save this file in two different file formats. |
| 09:12 | In the “Files of type” dropdown you will see Kml and Kmz options. |
| 09:20 | Kmz is the compressed version of the Kml file. |
| 09:25 | Kmz file format is often used to save a large file. |
| 09:31 | You can choose either of the options mentioned here. |
| 09:36 | I will use Kml format to save the file. |
| 09:40 | Click on Kml format in Files of type field. |
| 09:45 | Click on the Save button at the bottom-right corner of the dialog-box. |
| 09:51 | Similarly save the Boundary file also in Kml format. |
| 09:56 | The two files Places in Maharashtra.kml and Boundary.kml are saved on Desktop. |
| 10:06 | Next we will open these two files created in Google Earth Pro in QGIS. |
| 10:13 | Open QGIS interface. |
| 10:17 | Click on Add Vector Layer tool from the left menu. |
| 10:22 | Add Vector Layer dialog-box opens. |
| 10:26 | Under Source field, click on Browse button. |
| 10:31 | Navigate to the Desktop folder. |
| 10:35 | Select both Places in Maharashtra.kml and Boundary.kml files. |
| 10:42 | Click on Open button. |
| 10:45 | Click on Open button in Add vector layer dialog-box. |
| 10:50 | In the Select vector Layers to add dailog-box click on Select All button.
Click on OK button. |
| 11:01 | Both the files imported are now added as layers on the QGIS canvas. |
| 11:08 | These layers can be used for further analysis using tools in QGIS. |
| 11:15 | Let's summarize.
In this tutorial we have learnt to Download and Install Google Earth Pro. |
| 11:23 | Use Google Earth Pro to navigate and create a dataset. |
| 11:29 | Create point and polygon files in Kml format using Google Earth Pro. |
| 11:36 | Open Kml files in QGIS. |
| 11:40 | Assignment
