# Spatial data as WKT nodes for KNIME
# Spatial Processing Nodes for KNIME

The "Spatial data as WKT" collection of nodes
The "Spatial Processing Nodes" collection of nodes
propose to read and write spatial data from various formats, and provide basic transformation, filtering and visualization features.

This workflow demonstrates how to read data from the [ESRI shapefile format](https://en.wikipedia.org/wiki/Shapefile).
The node "Read shapefile as WKT" decodes the geometries and produces one row per geometry.
The node "Read from Shapefile" decodes the geometries and produces one row per geometry.

* open the output table of one of these nodes, and observe how the geometries are encoded in a column "the_geom"; this format is the Well-Known Text format.
* compare the outputs of the various nodes; observe how the geometries can be lines of polygons

# Things to try

* change the location of the output file by tuning the "Write WKT as a Shapefile" configuration
* change the location of the output file by tuning the "Write Geometris into Shapefile" configuration
* Run the workflow
* Observe the warnings emitted by the node: the ESRI shapefile format is a bit dated, and suffers many limitations in the column titles size, the count of columns and others. When these limitations are met, the node will adapt your data so it can be written and warn you.
* Open the resulting file with a [GIS sofware](https://en.wikipedia.org/wiki/Geographic_information_system) like [qgis](https://www.qgis.org), and check the data was written the right way.
