This page lists the various Geo components provided in SDI. This list is meant to grow as the project evolves. The Geo family is composed of 9 sub-families. All Geospatial components are also compatible with all Talend Open Studio Java components (database access, Internet, file manipulation, logging, processing, …).
Components of the File family are input and output components that can read from and write to files of different formats.
All output components will allow metadata creation using an ISO19139 XML template and setting the following properties:
The ISO19139 template could be adapted to your context (setting default point of contact, organisation name, …).
SDI automatically produced :
Components of the Database family are input and output components that can read from and write to different geospatial-enabled databases.
Currently, only the PostGIS database is supported:
Components of the Calculators family do some calculation on each feature of their input flows. sAreaCalculator, sCoordinateFetcher, sDecimalDegreesCalculator, and sLengthCalculator augments their input flows with new columns on their output flows. For example, sAreaCalculator adds the area column.
For each input feature, sBufferCalculator, sCentroidCalculator, and sEnvelopeCalculator output a feature whose geometry is, respectively, the buffer, centroid, and envelope of that input feature's geometry.
Components of the Collectors family perform an aggregation operation based on a GROUP-BY
column.
Name | Description | |
---|---|---|
![]() | sBoundingBoxAccumulator | Creates bounding box for groups of features. |
![]() | sConvexHullAccumulator | Creates convex hulls for groups of features. |
![]() | sNeighborFinder | Find neighbor features |
Components of the Geometric Operators family apply some geometric operator to their input features.
Components of this family perform various manipulations on their input features.
s2DPointReplacer creates a point object from x and y columns in its input flow.

---|---|---|
![]() | sFindPlaceName | Use GeoNames webservice to find nearby place name / reverse geocoding |
![]() | sFindPostalCode | Use GeoNames webservice to find nearby postal codes / reverse geocoding |
Metadata conversion is performed using XSLT transformations on metadata XML files. Each of these enables transforming a metadata file from one standard or profile to another.
Metadata publication allows SDI to publish metadata into an existing metadata catalogue (ie. GeoNetwork opensource).
Understand your spatial data. Tightly integrated with SDI Workbench, the UDig User friendly Desktop Internet GIS Viewer lets you quickly inspect your spatial data's geometry and attributes - before, after, and even during the transformation process. You can use it to examine features, identify attributes and values, and enhance the display using color, symbols and labelling.
