{{RewriteNote| This page Impact Scoring Tool is being rewritten'''Location based'''. The result will be a report i.e. the scores will not automatically be stored in the {{IMSMANG}} database per Location. <br/>'''[[PriSMA]]''' may calculate scores per Land/Hazard and as well Country structure/Admin area. }}

==Introduction==__NOEDITSECTION__
The Impact Scoring tool allows Mine Action Programmes to perform complex impact analyses of {{IMSMANG}} data. The tool is intended to help programmes to analyse several impact scenarios during their prioritisation and resource allocation process.
Using the Impact Scoring Tool, information managers can select which land factors to evaluate in an analysis. The tool has advanced capabilities to assess the impact of land on individual locations according to multiple-factor weighting schemes. The assessment can be done by using traditional impact factors (recent victims, blocked agriculture, blocked roads, blocked water source, etc) or any other data element from land stored in {{IMSMANG}}. Each factor must be given a weight which will enable to calculate and assign the impact score for each location'''[[Location Summary Window | Location''']]]. The final output is a list of locations ranked by impact based on the factors and weightings determined for that analysis.
{{IMSMANG}} allows information managers to create multiple scenarios using the Impact Scoring tool that can be run simultaneously to determine which factors are more important. {{IMSMANG}} also allows information managers to customise the display of the resulting analysis on the map. Both the factors and scenarios used in impact scoring and the resulting analyses can be saved within {{IMSMANG}} to allow planners to compare changes over time.

The IMSMA impact scoring tool computes a score for '''Locations ''' to determine how much the Location is affected by the existence of ordnance. The impact scoring tool allows you to select factors—the land, education, and/or victim item attributes—you would like to evaluate. After selecting the factors, you assign weights to each factor. The weight is a numerical value that signifies the importance of the factor relative to other factors, and its effect on the impact score for the Location. The combination of factors and their weights define a '''scenario ''' in the impact scoring '''template'''. You can define an unlimited number of scenarios with different factors and weights to test and compare the resulting impact scores.
The impact scoring tool allows you to limit the impact scoring to specific Country Structure nodes and time periods. You can customise the scoring ranges which are used to '''group ''' the Locations in classifications that denote levels of impact.
The '''impact score ''' of a Location is the sum of the '''factor ''' scores. The factor score is calculated by multiplying the '''weight ''' of the factor with the point value of the factor. The point value of a factor can be determined in one of two ways. If the factor contains a count, the count is used as the point value. For other factors, a point value of 1 is assigned if the factor tests positive. It is important to note that a point value is only assigned once regardless of how many times the factor tests true for the Location. This process is repeated for all factors in the scenario.
The impact scores can be saved so that you can either view the results at a later time, recompute the scenario scores using different factor scores, or export the results to a spreadsheet for further analysis.
