Open Source Software
Barista is expected to find a range of applications in for surveying and mapping applications, particularly for people working with satellite imagery. The main features of Barista are:
- > High-accuracy geopositioning from high-resolution satellite imagery (HRSI) via bias-corrected RPCs (suited to IKONOS and QuickBird), a rigorous physical model (eg for SPOT5 and ALOS) and the affine projection model
- > Ortho-image generation
- > Pansharpening
- > Monoplotting of points, lines and buildings to create 3D models from single images (requires an underlying DEM); affords building height determination.
The source code is hosted in Bitbucket and is freely available. It can be accessed at https://bitbucket.org/crcsi/baristasource/overview .
The latest stable builds are released as installers and are available for download at https://bitbucket.org/crcsi/baristasource/downloads .
The CRCSI would love contributions from the open source community, so please feel free to fix bugs, improve code, add functionality and provide documentation. If there are any questions feel free to get in touch with Riyasdeen Basheerahamed on firstname.lastname@example.org
Barista is a low-cost software system for data processing and metric geo-information extraction from high-resolution satellite imagery (HRSI).
It was created from a CRCSI research project at The University of Melbourne. Barista’s strength is that it offers easy-to-use, commonly needed spatial information extraction tools which are currently available only in high-end specialist digital photogrammetric workstations. This makes it an ideal tool for practitioners and non-specialists seeking to extract spatial information from HRSI, especially from single images from the Ikonos, Quickbird, SPOT5 and ALOS satellites.
It has been licensed for use to the multi-national company Infoterra and is currently being trialled by Pasco Corporation, the Australian Department of Defence, SKM, NSW Land and Property Management Authority and the Government of Bhutan.
Of particular note is the implementation of Barista in Geoscience Australia business processes to improve threefold their production rates for orthoimage generation from ALOS, PRISM and AVNIR imagery.
