Checking the "Enable advanced options in modules" box in the Settings module will result in additional options to be accessible to the user across different modules of AccessMod, as shown in the information reported in the following table:
Module/tool | Section | Advanced option | Description |
|---|---|---|---|
Data | Filter | Show internal data check button | Checking this button will make several types of internal data sets visible to the users (e.g., "friction", "speed", and "landcover merged bridge" raster data sets) in the "Available Data" table. See below for an explanation of these data sets. |
Toolbox/Merge land cover | Roads tab | Show checkbox to "Do not add 1000 to class < 1000" | If this button is checked, the values of the road categories (if <1000) will be kept as they are defined in the road layer (and 1000 will not be added to these categories) |
The internal data sets are the following
- Friction raster of class “friction”: Raster format layer containing the spatial distribution of the frictions (i.e. the resistance that one encounter when moving across the cells in a raster format layer). This is expressed in number of seconds to travel through a cell.
- Speed raster of class "speed": Raster format layer containing the spatial distribution of the speeds used in the analysis. The values in the raster correspond to a composite suite of numbers. The first number is the code for the travelling mode (1: walking; 2: bicycling; 3: motorized). The six following numbers is the speed in km/h, with the first 3 numbers for the integer part, and the three following ones for the decimal part. As an example, the number "2012500" corresponds to bicycle with a speed of 12.5 km/h.
