Updating google earth image
Here are a few tips and tricks on how I use historical images.
Through the years, the images have been taken at different times of the day.
KML uses a tag-based structure with nested elements and attributes and is based on the XML standard.
All tags are case-sensitive and must appear exactly as they are listed in the KML Reference. Within a given element, tags must appear in the order shown in the Reference.
In the current image, a potential campsite might be shaded where you can’t make out the size of the space or see if there is a campfire ring, but it might be shown in full sunshine in an older historical image, allowing you to get a better look at it.
The images have been taken at different times of the year, allowing you to gauge how likely the campsite might be occupied when you plan to visit.
If you're familiar with XML, you will also be interested in the KML 2.2 Schema.These features include placemarks, descriptions, ground overlays, paths, and polygons.The second section describes features that require authoring KML with a text editor.When a text file is saved with a Tip: To see the KML "code" for a feature in Google Earth, you can simply right-click the feature in the 3D Viewer of Google Earth and select Copy.Then Paste the contents of the clipboard into any text editor.
To view the historical imagery, click on the “year” button on the bottom left corner of your laptop screen, which will display the range of years available in the top left corner of your screen.
