AccessMod needs a vector format GIS layer containing the geographic locations of the health facilities to be considered in the physical accessibility, geographic coverage and referral analysis as well as scaling up analysis when taken into account. These locations should be expressed in the same projection system as the DEM (see Section 3.3.1.1)
Depending on the analysis to be performed, the facilities in question can either all be placed in the same layer or in separated layers.
The attribute table of this/these GIS layer(s) should at least contain:
- A unique identifier to appear in the resulting tables generated by AccessMod (cat field in the example below).
- The maximum coverage capacity of the health facility when conducting the geographic coverage analysis (see Section 5.5.4). Annex 2 provides more information on this parameter and describes an approach to calculate it (capacity field in the example below).
In addition to the above, it is also recommended to keep the official name of the facility in the attribute table as per the example presented here below.
