The columns presenting a label starting with “am” are not coming from the attribute table, but have been generated by AccessMod. These particular columns are the following:

- "amSelect": allows you to select/unselect the facilities to be run in the analysis

- "amOnBarrier": informs whether the health facility is located (“yes”) or not (“no”) on a barrier. The analysis cannot be performed if health facilities are located on barriers. If one or several of the health facility(ies) is/are located on a barrier, you can do one of two options:

• Decide to proceed without the facility(ies) in question by un-selecting them from the "amSelect" column and proceed. However, beware that in this case the results from the analysis will not consider the entire health facility network.
• Correct the health facility layer to move those located on barriers. This can be done either using the dedicated AccessMod tool (see Section 3.3.15.6) . This operation must be completed outside AccessMod, or in your GIS software and outside of AccessMod (in this case the new updated layer must be imported in AccessMod).

- "amOnZero": informs whether the health facility is located (“yes”) or not (“no”) on a landcover category that has a speed of zero set in the travel scenario table. In this case the analysis cannot be performed, and you can do one of two options:

• Decide to proceed without the facility(ies) in question by un-selecting them from the "amSelect" column and proceed. However, beware that in this case the results from the analysis will not consider the entire health facility network.
• Correct the corresponding speed(s) of travel in the travel scenario table, by giving them a value greater than zero.

- "amOutsideDEM": informs whether the health facility is located (“yes”) or not (“no”) outside of the DEM extent (i.e. outside of the extent of the project). Facilities that are outside the DEM extend cannot be considered in the analysis and their coordinates must be corrected if there are supposed to be within the DEM extent.

- "amCatLandCover": provides information on the land cover classcategory, i.e. the pixel value in the land cover raster layer. 

- "amDemValue": provides information on the DEM, i.e. the pixel value in the DEM raster layer.
