GIS Functionality
below is listed the key functionality requirements planned for the hydrogeological data for map presentation.
Under Construction.
Internet GIS Tool
Drafted by David Banks, Sen. Hydrogeologist
"I envisage the internet based GIS tool having 2 main drop-down menus. One for point data and one for background data.
In the following descriptions, I have used
BLACK BOLD to indicate primary menu options
Red Bold to indicate secondary menu options
Green to indicate tertiary menu options
Proposed Background Layers
GEOLOGICAL MAP
Geological units (click on polygon identify, with description)
Geological contacts
Faults
Dykes
Hydrogeological units (click on polygon identify, with description) (to be based on USGS naps, but reclassified by DB and hydrogeological team: cannot be selected at same time as geological units)
Mineral deposits (click to identify)
Contours on top of Ghory Formation (masl): Contours of subsea depth (in meters) of the Paleogene Ghory Formation in northern Afghanistan. Contour values and intervals are given in the attribute table. This dataset was digitized by USGS. Source: Ivanov and Didura. ghorydpafg.shp from USGS.

Contours on top of Qezeltash Formation (m asl): Contours of subsea depth (in meters) of top of Hauterivian sandstones (Qezeltash Formation) in northern Afghanistan. Contour values and intervals are given in the attribute table. This dataset was digitized by USGS. Source: Ivanov and Didura. qezeldpafg.shp from USGS.

Main roads
OTHER BASE MAPS
I have no strong feelings on this, but we could include satellite images or street maps. BUT KEEP IT SIMPLE
Proposed Point Data (If the point is clicked on, a screen summarising the basic data appears, with the option to download a table of the full well record)
In all menus below, boreholes where “Type” = “Hydrocarbon” are excluded, except in the case where the menu items “Hydrocarbon wells” or “geophysical log” are selected
GROUNDWATER POINTS (based on the “Type” field)
All
Dug wells
Drilled boreholes
Springs
KarezesGROUNDWATER SALINITY (based on the electrical conductivity column)
All wells/boreholes/springs/karezes/unknown groundwater with EC info)
0-500 µS/cm
500-1000 µS/cm
1000-1500 µS/cm
1500 - 2000 µS/cm (colours of symbols increase through blue-green
2000 - 3000 µS/cm -yellow-orange-red) as EC increases)
3000 - 5000 µS/cm
5000 - 10000 µS/cm
>10000 µS/cm
WELLS WITH GROUNDWATER LEVEL DATA (based on the static water level column)
All wells / boreholes / unknown groundwater with water level data
Groundwater level 0-10 m below ground level
Groundwater level 10-20 m bgl
Groundwater level 20-30 m bgl
Groundwater level 30-40 m bgl
Groundwater level 40-50 m bgl
Groundwater level 50-75 m bgl
Groundwater level >75 m bgl
(symbols increase in colour from pale blue to deep blue as depth increases)
WELLS WITH DEPTH DATA (based on the well depth column)
All wells / boreholes / unknown groundwater with depth data
Depth = 0-10 m
Depth = 10-20 m
Depth = 20-30 m
Depth = 30-40 m
Depth = 40-60 m
Depth = 60-80 m
Depth = 80-100 m
Depth = 100-120 m
Depth = 120-150 m
Depth = 150-200 m
Depth = >200 m
(Symbols to be colour coded according to depth)
I don’t believe we need to provide the options for selecting according to diameter, construction materials, pump type, year...etc. It will make it too complicated)
SPECIFIC WELL TYPES
Monitoring wells (all wells and boreholes where Use = observation)
Features marked on 1968 Soviet Hydrogeological map (all features from GRO_Wells and springs from 1968 Soviet Hydrogeological Map QA2.xls)
