The merged land cover distribution grid resulting from the application of this tool is required to perform the different analysis in AccessMod.
Data for the Population adjustment tool:
...
- Health facility locations: Vector format layer containing the location of each health facility (point) considered in the analysis with the indication of themaximum population coverage capacity for each of them in the attribute table
- Population distribution: Raster format layer containing the spatial distribution of the target population.
- Travel scenario: Table containing a traveling speed and a mode of transport (walking, motorized or bicycling) for each class in the merged land cover distribution grid.
- Digital Elevation Model (DEM): Raster format data containing the spatial distribution of altitudes used if anisotropic movements are considered in the analysis.
Data for performing the referral analysis:
...
- Health facility locations: Vector format layer containing the location of health facilities for both groups used in the referral process (FROM and TO).
- Travel scenario: Table containing a traveling speed and a mode of transport (walking, motorized or bicycling) for each class in the merged land cover distribution grid.
- Digital Elevation Model (DEM): Raster format layer containing the spatial distribution of altitudes used if anisotropic movements are considered in the analysis.
...
Data for performing the zonal statistics:
...
- Population distribution: Raster format data layer containing the spatial distribution of the target population.
- Travel time distribution layer resulting from the accessibility analysis (raster format data).
- Boundaries of the zones: Vector format layer containing the boundaries of the zones considered for obtaining the statistics (administrative divisions, health districts,...).
Data for performing the scaling up analysis:
...
- Population distribution: Raster format layer containing the spatial distribution of the original total target population over the study area.
- Residual population distribution: Raster format layer the spatial distribution of the population not covered after conducting the geographic coverage analysis.
- Travel scenario: Table containing a traveling speed and a mode of transport (walking, motorized or bicycling) for each class in the merged land cover distribution grid.
- New health facility capacity: Table containing the necessary information for locating a new health facility during the analysis.
- Health facility locations: Vector format layer containing the location of the existing health facilities if they are to be considered in the analysis.
- Digital Elevation Model (DEM) Raster format layer containing the spatial distribution of altitudes used if anisotropic movements are considered in the analysis).
- Exclusion areas: Vector or raster format data containing the extension of the areas over which new facilities cannot be located.
- Priority area distribution: Raster format data containing the spatial distribution of areas to be considered in priority during the scaling up analysis.
...
Please note that exclusion and priority areas can also be defined in AccessMod based on other vector format data. The vector format layers used in this case will have to be imported in AccessMod prior to conducting the analysis.
