8. Building Interactive Web Apps#
8.1. Introduction#
8.2. Technical requirements#
To follow along with this chapter, you will need to have leafmap and several optional dependencies installed. If you have already followed ch1:install - Installing leafmap, then you should already have a conda environment with all the necessary packages installed. Otherwise, you can create a new conda environment and install pygis with the following commands, which will automatically install leafmap and all the required dependencies:
conda create -n geo python
conda activate geo
conda install -c conda-forge mamba
mamba install -c conda-forge pygis
Next, launch JupyterLab by typing the following commands in your terminal or Anaconda prompt:
jupyter lab
Alternatively, you can use leafmap in a cloud environment without installing anything on your local computer. Click on one of the following links to launch a cloud-based JupyterLab server:
Once in the selected cloud environment, you can uncomment the following line and run the cell to install pygis, which includes leafmap and all the necessary dependencies:
# %pip install pygis
The installation process may take 2-3 minutes. Once pygis has been installed successfully, restart the kernel to enable the newly installed packages.
To begin, import the necessary libraries that will be used in this chapter:
import leafmap
