Schema and Attribute Details:

wld_trs_obstacles_wfp

objectid integer NOT NULL: ArcGIS ID obstype character varying(25): Obstacle type: Unknown, Flood, Mines/UXO, Roadblock, Road damage, Railway damage, Bridge damage, Culvert damage, Ferry, Checkpoint Official, Checkpoint Unofficial, Traffic restriction, Landslide, Wreckage, Ford, Trees

obsdate timestamp without time zone: Observation date of the obstacle

maxloadmt numeric(5:1): Maximum load that can go through the obstacle

locprecision character varying(25): Precision of the location Accurate => GPS coordinates, digitized from an high resolution satellite imagery or a detailled map (accuracy at the street level) Approximate => Precision which is not below the city/town level. It often corresponds to a point equivalent at the point of the city/town/village Bad => Feature with a very low precision. A feature exists in 1 area (province, region...) but we don't know where exactly, the reference (settlement) is impossible to find and the point is put randomly Unknown => No information regarding the precision

latitude numeric(8,5): Latitude of the point (Calculated automatically from the geometry)

longitude numeric(8,5): Longitude of the point (Calculated automatically from the geometry)

iso3 character varying(5): ISO3 code of the country where the feature is located. This field is calculated automatically at the database level with the bnd_adm0_a_ungiwg_2012 layer

country character varying(50): Name of the country where the feature is located. This field is calculated automatically at the database level with the bnd_adm0_a_ungiwg_2012 layer

lastcheckdate timestamp without time zone: Date of the last check of all (or a part) of the attributes. The date has to be specified manually during the edits

remarks character varying(1000): Notes/Description/Remarks - The user is free to enter any information that is necessary but cannot be stored in the others fields

source character varying(254): Source of the information. It could be the source of the geometry or the source of the main attributes. Several sources can be accepted for the same feature(list of names)

createdate timestamp without time zone: Date when the feature has been created. Calculated automatically at the database level while saving (commit) the edits.

updatedate timestamp without time zone: Date of the last update. Calculated automatically at the database level while saving (commit) the edits. Different of the lastcheckdate because the user can forget to specify the date manually or because sometimes we can do a quick edit (for example change the status or correct misspelling) without checking all attributes.

shape geometry: Geometry
