Geospatial Analytics in KNIME 101

Welcome to Geospatial Analytics in KNIME 101!

Geospatial Analytics is an increasingly essential field, as it allows us to extract valuable insights from location-based data. With the Geospatial Analytics Extension for KNIME, you can unlock hidden patterns and relationships within your datasets.

1. KNIME Installation and Admin Mode

2. GAEK Node Configuration Blank Issue

3. Missing Community Extensions

4. Install KNIME Keras Integration

conda create -n knimedlcpu python=3.6 h5py=2.8 tensorflow-mkl=1.12 keras=2.2.4 pandas=0.25.3 -c conda-forge
conda create -n knimedlgpu python=3.6 h5py=2.8 tensorflow=1.12 keras-gpu=2.2.4 pandas=0.25.3 -c conda-forge

5. Install KNIME Geospatial Env

conda env remove -n geospatial_env
conda env create -f https://raw.githubusercontent.com/spatial-data-lab/knime-geospatial-extension/main/knime_extension/geospatial_env.yml

6. SSL Verification Errors

If you encounter SSL errors while installing Python packages:

conda config --set ssl_verify false

7. Long File Path Error on Windows
