Q1. In the Places pane, when I right click on a single element, and choose properties…
As a Google Earth user I can change about the features:
• name of the feature – this will change the name of the feature KLM file
• description – I can add a link or image to the feature, I can also write a code in the body to give it additional special features
• style, color – I can change the color of the lines and areas, the opacity, and line width
• view – I can snapshot the current view to get the longitude and latitude. Also I can place a date/timestamp on the feature
• Altitude – I can change the view and fix the distance from the feature point
• Add – I can also add a folder, placemark, path, polygon, model, photo, network line, tour, and overlay an image.
How to save: I can save my changes to a place by saving it as a KMZ file, saving the map as a JPG image, and saving “my places” in the software application.

Q2. The difference between ArcGIS and Good Earth are the following:
ArcGIS is compatible with GIS databases and uses shapefiles, geodatabases, SQL servers, and more. Additionally, AcrGIS has ready-to-use map templates and user interfaces. It also has more technical support, and is cloud enable. Additionally, it also features more analytical tools that help GIS scientists to analyze spatial data more scientifically. However, the liscense for GIS is more expensive, it is slower to load if not properly configured, and it is also not compatible with other GIS applications.
Google Earth has a faster implementation than ESRI or open source platforms. Another benefit is that the software free, and also high performance maps which have detailed background maps/satellite imagery. However, there are no GIS and spatial analysis functions, which limit the analytical features of the software and requires a mashup to extend GIS functions.
