Plugins
Several plugins have been created to support or enhance the functionality of QGIS. Each plugin has different benefits and limitations, so be sure to familiarize yourself with your project to make sure you make the right selection. For example, using an API may be preferred to reduce processing times as calculations are being completed on external servers. On the other hand, you will have to plan ahead to use APIs that require accounts to generate permission keys, as it can take some time for your account to gain access. The table below shows the different functions each plugin offers to help with your selection. For more information on a particular plugin, click the embedded link.
