The main modules are” (https://www.ee.co.za/article/web-mapping-solution-assesseffect-sea-level-rise.ht):
1. Display functions—Map tools.
2. Cartographic presentation.
3. Utilities.
4. Mashup module.
5. Layer manager module.
6. Sea level rise scenarios module: This module contains four levels to study:
a. Scenario 1: sea level rise from 0 to 25 cm.
b. Scenario 2: sea level rise from 0 to 50 cm.
c. Scenario 3: sea level rise from 0 to 75 cm.
d. Scenario 4: sea level rise from 0 to 100 cm.
For each scenario, the user can:
• Select any scenario and show all affected districts by the selected scenario also
the user can display more than one scenario at the same map view to compare.
The results can be displayed in different format (maps, tabular and graphs).
• Select any Markaz/district in the study area and locate it geographically on the
base map. For any selected Markaz, the application provides:
– The number of population and the number of families.
– The affected area of the selected markaz divided by total markaz area for each
scenario.
• For each scenario, the user can select any affected district and retrieve the
labor force information about it. The labor force is classified into eleven categories according to the Central Agency for Public Mobilization & statistics
classification.
• Select any hotspot point. The hotspots data include urban areas, railway stations,
archaeological sites, airports, industrial zones, exchanges, resorts and industrial
spots. For any selected hotspot the application shows its location on the map and
which SLR scenario(s) may affect it.
• Locate any GPS point by inputting its latitude and longitude in decimal degree
format to check if it is affected by any SLR scenario or not.
7. Population distribution module.
