Analysis Based on Risk MapsAnalysis Based on Risk Maps

• LUA programming language• LUA operators:

arithmetic: + - * / ^ relational: == ~= < > <= >=logical: and or not mathematical: math.abs math.acos math.asin math.atan ….

• TerraLib operators:– zonals: maximo minimo media conta_amostras– historical: operador_historico– grid: amostra


ExampleExample

Risk Model Using Risk Model Using Hydrometeorological Data in a Hydrometeorological Data in a GridGrid

local ca = maximo(‘total rain')if ca < limiar_ca thenreturn 0 -- Ok

elseif ca < limiar_ca * 1.2 thenreturn 2 – Attention level

elsereturn 4 – Maximum Alert level

end


ExampleExample

Risk Model Using Point Data Risk Model Using Point Data (DCPs)(DCPs)local rain = media(‘dcp_data’,'pluvio')if rain == nil thenrain = media('rain_grid')endif rain < threshold thenreturn 0 -- Ok

elseif rain < threshold * 1.2 thenreturn 2 – Attention level
