Schema

Transport

Type: Blank Node

View examples

The transport of a Product, Input, or item of Infrastructure to or from a Cycle.

Field Type Required Definition
term Term Yes

A reference to the Term describing the Transport mode.
description string No

A description of the Transport mode.
value number No

The distance transported times the number of tonnes transported. E.g., if 40 kg of Urea (kg N) are used during the Cycle, the nitrogen content of Urea is 45.5%, and the urea was transported 91 km, this field is calculated as 40 / 1000 / 45.5% * 91 = 8 tonne kilometers.

sd number No

The standard deviation of value.
min number No

The minimum of value.
max number No

The maximum of value.
statsDefinition string No

What the descriptive statistics (sd, min, max, and value) are calculated across, or whether they are simulated or the output of a model. Spatial is descriptive statistics calculated across spatial units (e.g., pixels) within a region or country.

Possible values are: cycles, replications, other observations, spatial, regions, simulated, modelled
observations array[number|null] No

The number of observations the descriptive statistics are calculated over.
distance number No

The distance transported in kilometers.
distanceSd number No

The standard deviation of distance.
distanceMin number No

The minimum of distance.
distanceMax number No

The maximum of distance.
distanceStatsDefinition string No

What the descriptive statistics (distanceSd, distanceMin, distanceMax, and distance) are calculated across, or whether they are simulated or the output of a model. spatial refers to descriptive statistics calculated across spatial units (e.g., pixels) within a region or country. time refers to descriptive statistics calculated across units of time (e.g., hours).

Possible values are: cycles, replications, other observations, time, spatial, regions, simulated, modelled
distanceObservations array[number|null] No

The number of observations the descriptive statistics for distance are calculated over.

returnLegIncluded boolean Yes

Whether the return leg is included in value and distance.
methodModel Term No

A reference to the Term describing the method or model used to acquire or estimate these data.

methodModelDescription string No

A free text field, describing the method or model used to acquire or estimate these data.

methodClassification string No

A classification of the method used to acquire or estimate the term and value. Overrides the defaultMethodClassification specified in the Cycle. methodClassification should be specified separately for inputs (see Input) and practices (see Practice).

  • physical measurement means the amount is quantified using weighing, volume measurement, metering, chemical methods, or other physical approaches.
  • verified survey data means the data are initially collected through surveys; all or a subset of the data are verified using physical methods; and erroneous survey data are discarded or corrected.
  • non-verified survey data means the data are collected through surveys that have not been subjected to verification.
  • modelled means a previously calibrated model is used to estimate this data point from other data points describing this Cycle.
  • estimated with assumptions means a documented assumption is used to estimate this data point from other data points describing this Cycle.
  • consistent external sources means the data are taken from external datasets referring to different producers/enterprises:
    • Using the same technology (defined as the same System or the same key Practices as those specified in the Cycle);
    • At the same date (defined as occurring within the startDate and endDate of the Cycle); and
    • In the same region or country.
    Modelling or assumptions may have also been used to transform these data.
  • inconsistent external sources means the data are taken from external datasets referring to different producers/enterprises:
    • Using a different technology (defined as a different System or using different key Practices to those specified in the Cycle);
    • At a different date (defined as occurring within the startDate and endDate of the Cycle); or
    • In a different region or country.
    Modelling or assumptions may have also been used to transform these data.
  • expert opinion means the data have been estimated by experts in the field.
  • unsourced assumption means the data do not have a clear source and/or are based on assumptions only.

Possible values are: physical measurement, verified survey data, non-verified survey data, modelled, estimated with assumptions, consistent external sources, inconsistent external sources, expert opinion, unsourced assumption
methodClassificationDescription string No

A justification of the methodClassification used. If the data were estimated with assumptions this field should also describe the assumptions. This is a required field if methodClassification is specified.

source Source No

A reference to the Source of these data.
inputs List[Input] No

The Inputs into the Transport process (e.g., diesel).

inputs cannot be duplicated. The following fields determine whether an Input is unique: term.@id, dates, startDate, endDate, operation.@id, country.@id

practices List[Practice] No

The Practices used.

practices cannot be duplicated. The following fields determine whether a Practice is unique: term.@id, description, key.@id, dates, startDate, endDate, areaPercent, ownershipStatus

emissions List[Emission] No

The Emissions created during Transport.

emissions cannot be duplicated. The following fields determine whether an Emission is unique: term.@id, dates, startDate, endDate, depth, inputs.@id

Internal Properties

The following properties are automatically set when data are uploaded to the Hestia platform. If they are included in a file which is uploaded, they will be overwritten.
