Parameter: optimizeFor

Data Type: GPString
Display Name optimizeFor
Description: The optimization method to use for calculating the viewshed. SPEED—This method optimizes the processing speed, trading some accuracy in the result for higher performance. This is the default.ACCURACY—This method is optimized for accuracy in the results, at the expense of a longer processing time.

Parameter: analysisType

Data Type: GPString
Display Name analysisType
Description: Specifies the type of visibility analysis you wish to perform, either determining how visible each cell is to the observers, or identifying for each surface location which observers are visible. FREQUENCY—The output records the number of times that each cell location in the input surface raster can be seen by the input observation locations (as points or as vertices for polyline observer features). This is the default. OBSERVERS—The output identifies exactly which observer points are visible from each raster surface location. The allowed maximum number of input observers is 32 with this analysis type.
