HydroGlobe provides hydrologists, educators and watershed managers instantaneous access to time series data for any watershed of interest. HydroGlobe takes care of the necessary data access, processing and aggregation behind the scenes.


Middle school students working with geospatial imagery and GABBs tools to learn research concepts at TOTAL summer camp in 2016 & 2017.


LeafSpec provides georeferenced plant physiological information from data collected in the field using hand-held sensors.


iData allows researchers to browse, discover, upload, share and publish their scientific data. The iData file browser supports metadata management, simple preview and scientific tool launch.

MultiSpec Online

MultiSpec is an image processing tool to display and analyze geospatial images that has been used by more than 600 researchers, teachers and students via

Data API

The data service API is used to enable field data collection from mobile devices and interoperability with other cyberinfrastructures.


PyMapLib is a Python mapping and widget library that has been used to create user interfaces for various tools including the AGMIP data aggregator, WinTx winter weather explorer and FLAT downscaler.


GeoVis is a dedicated render server for use in visualizing 2D and 3D geospatial data.

SWATFlow and Streamflow Viewer

SWATFlow allows hydrologists to import, execute and visualize the results of SWAT (Soil and Water Assessment Tool) models from either local files or the HydroShare science gateway. The Streamflow Viewer provides a visualization tool for the streamflow extents calculated by SWATFlow.

GABBs is an NSF-funded project to create a powerful Web-based system that will allow researchers worldwide to manage, curate, share, analyze and visualize geospatial data for purposes ranging from predicting damaging floods to projecting climate change effects on the poor. The project builds geospatial data hosting, processing and sharing capabilities into Purdue’s HUBzero platform.

GABBs helps researchers and educators create and share geospatial data and tools in an easy-to-use, free, open source platform.


GABBs toolkits lower the barrier to developing map-enabled geospatial tools by non-expert users with minimal programming effort. The PyMapLib Python mapping library, Rappture map elements and GeoVis render server provide easy to use map widgets, APIs and visualization infrastructure for diverse geospatial data.

Data Capabilities

The GABBs data management building block, iData, allows researchers to self manage, browse, discover, share and publish scientific data. iData supports automatic metadata extraction, preview and scientific tool launch directly from the iData file browser. Remote data transfer into iData via either a REST API service, SFTP or a mobile app is also supported.


GABBs tools support a range of operations on geospatial data from wizard interfaces for building intuitive displays to complex geospatial processing, analysis and transformation. This includes the MultiSpec Online tool that supports image processing capabilities for remote sensing hyper and multispectral images.

Delivery Mechanisms

Amazon Web Services (AWS)

Our GABBs AWS CloudFormation template can be used to setup a complete GABBs-enabled HUBzero 2.1 hub on the AWS Cloud Computing platform. This setup process requires no programming or system administration experience and users can be up and running with a hub in under an hour. Refer to the instruction video for a walkthrough of the CloudFormation process and a demonstration of the resulting hub's features.

Virtual Machine

A preconfigured GABBs 1.0 virtual machine image can be downloaded and used on your own personal computer or laptop to test a simple HUBzero hub that comes with MultiSpec and iData installed.

Install from Linux Packages

If you currently host your own HUBzero hub or plan to host one in your own infrastructure, then you can add individual GABBs building blocks to the hub by installing our open-source Linux packages for RedHat/CentOS. Refer to our documentation for detailed instructions on installing individual GABBs building blocks to your hub.
