This is a Ergo Training Manual for the visiting students (Eujeong Choi and Jaebeom Lee) from S. Korea. This document can be a good starting base for the official manual.



Hands on with Ergo

Built-in Attenuation functions on Ergo

How to create a scenario earthquake UI

Create Ergo Input Dataset (ESRI Arc/Info Grid ASC format) from USGS shakemap data (by using QGIS)


Rasterize (vector to raster)

  • Since the data from USGS site is in vector format (polygons), it needs to be converted to ASC format for Ergo Input
  • Open the shapefile (pga.shp) in QGIS (we will create PGA raster data)
  • Rasterize the vector data by the menu: Raster - Conversion - Rasterize
    • Input file: the shapefile for conversion
    • Attribute field: Value
    • Output file: select Geotiff  and give a name (extension: tif) 
      • Note: current version of QGIS rasterizer can't support ASC format directly
    • Raster size
      • default: 3000, 3000
      • You can increase the size to decrease the file size (but sacrifice the accuracy)

Geotiff to ASC

  • Convert the format from Geotiff to ASC by the menu: Raster - Conversion - Translate
    • Input layer: the geotiff layer you created from previous step
    • Output file: select Arc/Info Grid Ascii (ASC) and give a name

Importing Raster data as a hazard

  • Convert USGS vector to raster and import into Ergo, see Importing ASCII Raster guide
  • Use the imported hazard in an Ergo damage analysis (e.g. building damage analysis).

Adding Attenuation Model

  • Create a new plugin for the attenuation model, add dependencies
  • Create a new extension and generate the class for the new model
  • Add plug-in to Ergo launcher to make new model available
