Changes in the Terra-i website

Jhon Tello

Recently changes were made to some data viewer controls from our website. Furthermore the website was migrated to a new virtual server on Amazon, this will provide a better service to our users, ensuring better connectivity speed.

Changes made to the data viewer ( include new buttons on the upper right corner as explained below:

1. Layers button displays a window that allows you to toggle the layers we have available on the map; such as protected areas, indigenous areas. In this section, users now have the option to hide and show the layer of Terra-i data. In addition, the legend of the data is shown.

2. The search button displays a window where you can search in different administrative levels (country departments, protected areas, indigenous areas, ecosystems). This control contains a checkbox to activate the polygon search at countries and departments, for the other levels (protected areas, indigenous areas, ecosystems) markers on the map are displayed, clicking on the polygon or the markers you can do the search. Also within this coordinate search option was included, this option displays a marker on the map showing the position (latitude, longitude) and the address.

Search section

3. The statistics button is activated when a search is performed, and displays a window with dynamic statistical graphics (near real time and annual cover loss). In each graphic is an icon in the top left corner to zoom in on the graph. When zoom is performed at the graphic download icon appears in the top right corner of the chart.

4. The graphic of statistics in near real time has on the right side the legend of the different years as shown in the figure below in the red box. Initially is shown on the graphic the statistics for the last two years. The user can move the mouse over each line on the graphic to display values and toggle the year that you wish to view by clicking on it. When given zoom over the graphic can be made the same events and also download the graphic.

5. The color of the polygon to define the limit of the desired area was replaced by brown color. This change was made because the previous color (yellow) caused confusion with the layer of Terra-i detections that begins with this color.

Amazon EC2

The Terra-i website is now hosted on “Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers”. [1]

“Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing you to quickly scale capacity, both up and down, as your computing requirements change”. [1]

Some of the changes are suggestions of users and others from our team, all seeking to facilitate and improve our users' experience in the use of our data.
