AREA -------------------------

Lower Mekong Basin including Cambodia, Laos, Thailand and Vietnam in LMB part

DESCRIPTION ------------------


Mapping of irrigation canal location as of 2001


SOURCE MAP -------------------

Cambodia: - 1:50,000 scale topographic maps, UTM Zone 48, US series L7016 (1960s/70s)

Laos: - 1:50,000 scale topographic maps Gauss reprojected to UTM Zone 48

Thailand: Various inculding project maps at various scales

Vietnam: - 1:100,000 scale maps with supplemenmtary information from Sub Institute of Water Resource Planning (SIWRP)


SOURCE DATA SET --------------

Cambodia: - 1:50,000 scale topographic maps, UTM Zone 48, US series L7016 (1960s/70s)

Laos: - 1:50,000 scale topographic maps Gauss reprojected to UTM Zone 48

Thailand: Various inculding project maps at various scales

Vietnam: - 1:100,000 scale maps with supplemenmtary information from Sub Institute of Water Resource Planning (SIWRP)


SOURCE AGENCY ----------------

MRCS


GENERATION -------------------

Union from 4 original datasets has been made by reproject from zone 47 in Thai part to zone 48 and from WGS84 of Vietnam delta part to UTM 48.

STATUS -----------------------

Last update: December 2001

Completion status: 100 %


COMMENTS ---------------------

Cambodia:
Proj_id1 and proj_id2 have been added as it appears some of the irrigation areas are served by more that one project.
Temp_id refers to the original ID during digitising and should be eventually deleted after checking of data.
Note: temporary notes used during digitising and should be eventually deleted.
Area_id	Not required as only 1 area per scheme.
Proj_id1 and proj_id2 provided as in some cases not clear which area is linked to which project.
Irrigation area is difficult to define in Cambodia and more work is required to improve the accuracy, and availability of irrigation area data.
Temp_id and note are temporary information used during the digitising and should deleted after final checking.

Laos:
Follows LRIAD format. Irrigation area boundaries require further checking.Temp_id is a temporary ID used during digitising.

Thailand:
There is some overlap of the irrigation areas from the different agencies. To clearly present this information an additional field has been added 

Vietnam:
Original units decimal degrees in Map Info Format. Reprojected to UTM 48
To represent the complete situation the data base shows all the blocks-the function of the blocks can be seen in the ‘proj_function’ field in ir_data.dbf. 
Each block represents an investment and must be considered as part of the overall part of the system.
project_id	Unique Project ID code as above
Area_id	NA
Name	Name of project as above
Shape_area	Gross area of polygon in hectares
Crop_code Shows the main cropping in each block
