Registration and settings¶
The toolbox is free to use, but you must register an email address prior to using any of the cloud-based functions.
To Register, click the “Step 1: Register” button. Enter your email, name, organization and country of residence and select “Ok”:
You will see a meesage indicating your user has been registered:
After registering, you will receive an email from firstname.lastname@example.org with your password. Once you receive this email, click on “Step 2: Enter login”. This will bring up a dialog asking for your email and password. Enter the password you received from email@example.com and click “Ok”:
You will see a message indicating you have successfully been logged in:
Updating your user¶
If you want to change your username, click on “Change user”. Note that this function is only useful if you already have another existing account you want to switch to. To register a new user, see Registration. To change your user, enter the email and password you wish to change to and click “Ok”:
If you want to update your profile, click on “Update profile”. Update your information in the box that appears and click “Save”:
To delete your user, click “Delete user”. A warning message will appear. Click “Ok” if you are sure you want to delete your user:
If you forget your password, click on “Reset password” from the settings dialog box.
A password will be sent to your email. Please check your Junk folder if you cannot find it within your inbox. The email will come from firstname.lastname@example.org.
Once you receive your new password, return to the “Settings” screen and use “Step 2: Enter login” to enter your new pasword.
Click “Edit advanced options” to bring up the advanced settings page:
From the advanced settings page, you can change settings including enabling/disabling debug mode, and loading pre-compiled binaries to speed up calculations in Trends.Earth.
Debug mode saves additional information on the processes that you run in Trends.Earth to the QGIS messages log (accessible by enabling the “Log Messages Panel” under “View” and then “Panels” on the QGIS menu bar).
To enable logging of debug messages, check the box. These messages may be useful when trying to problem-solve any issues you might encounter while using Trends.Earth.
Use binaries for faster processing¶
Some of the functions in Trends.Earth are available in versions that have been compiled using the Numba library. Numba can translate Python code into machine code (binaries), resulting in functions that run much faster. For users of Trends.Earth, this means being able to process data more quickly than in the standard version of Trends.Earth.
Because Numba is not supported within QGIS, and compiling files with Numba requires having additional software installed on your machine, we have made binaries available that you (optionally) download and use within Trends.Earth. This is intended to make it easier for our users to access the benefits of Numba without needing to install it themselves.
To access the binaries, first choose a folder on your machine where you would like to have them saved, by clicking the “Browse” button on the advanced settings screen. Once you have chosen a folder, click “Download” to download the binaries to your machine. After downloading the binaries, restart QGIS in order to enable them. Check the advanced settings page after restarting. If they are working correctly, you will see a message saying “Binaries are loaded”. If you have any trouble enabling the binaries, reach out to the Trends.Earth discussion group for help.
Not all of the functions in Trends.Earth can make use of the binaries, so don’t expect everything to run faster after you have installed them. The summary tool for SDG 15.3.1, however, should run much faster after installing the binaries, particularly if you are working with very high resolution custom datasets. In the future we will be adding support for other functions as well.
