InaSAFE 4.0 is released!

Version 4.0.0 brings with it the following changes: – Complete overhaul of the InaSAFE code base – Deprecated numpy / matrix based geometry manipulation – New reporting system including Jinja2 support – Experimental support for Infographics – Removed all impact functions in favour of a shared workflow for all hazards – Added support for exposure specfic thresholds in hazard metadata – Produce rich data outputs instead of simple HTML reports – Added new hazard support for Tropical Cyclone – Extensive updates to the help reference and a new help browser – Removal of all logic that uses interpolation to assess impact level – Application of standards to reporting and calculations for more consistent presentation – Ability to work with larger datasets in many cases (just be patient while analysis runs) – Speed ups and improvements to many parts of the code base – Improvements to the batch runner tool – Improvements to the shake grid importer tool – Port of the minimum needs tool to use our new architecture – Added support for analysis of irregular areas (as defined by aggregation layer) – Features or population outside of aggregation areas are no longer counted as part of the total exposure count – Added support for working with data subsets – Analysis no longer works only with local file sources – All geometry operations are performed using the QGIS API now – QGIS layers list items now have a context menu for InaSAFE – Input layers no longer need to be in EPSG:4326 – Moved realtime code to its own repository – Improved error handling system – Added profiling for all analysis steps so we can easily identify performance bottlenecks – Improved how partial overlaps with a hazard are managed (feature is assigned highest impact zone) – Generate rich provenance for use in reporting – Generate multiple sub products (impact layer, aggregation by hazard layer) – PDF Reports are generated directly once analysis completes – Earthquake sub-algorithm selection has been moved to the InaSAFE options dialog – ITB Bayesian algorithm is now default for earthquake – Earthquake analysis map output is now a boolean layer indicating if a cell contains displaced people – Many, many more improvements…
