Activities are the control and survey operations we conduct as part of the National Wilding Conifer Control Programme. Through activities we can monitor progress of the programme at a regional and national level.

What are activities?

Activities are the operations we perform as part of the National Wilding Conifer Control Programme. There are two types of activity that we capture in the Wilding Conifer Information System:

Control Activities

Control activities are the operations carried out to eradicate the wilding conifer infestations. Control activities are represented as blue polygons.

Survey Activities

Survey activities are the operations carried out to discover new infestations and re-evaluate the state of known infestations. Often times a survey is carried out as part of a control activity (e.g. search and destroy), in this case the activity should be recorded as a control activity. Survey activities are represented as green polygons.

Activities are characterised by their extent, represented in the WCIS as a polygon shape, and a common set of attributes for that extent, including:

  • Type
  • Method
  • Technique
  • Lead Agency
  • Contractor
  • Start Date
  • End Date
  • Total Team Hours
  • Cost
  • Comments

Each attribute is covered in more detail in the ‘Activity attributes’ section below.

How do I define the boundaries of an activity?

The boundaries of an activity will need to reflect the area of the operation that was carried out.

Control activities must:

  • represent the area of trees (infestation) that have been controlled
  • be contained within the boundaries of a single management unit
  • overlap with at least one operational area

Survey activities must:

  • represent the area that was explored in search of infestations
  • be contained  within the boundaries of a single management unit
  • overlap with at least one operational area

How do I record the extent of an activity?

There are a number of methods available to map the extent of an activity, including:

Shp and Gpx files (Data Importer Application)

The extent of an activity can be recorded using a tracking tool which captures a .gpx or .shp file of the path, or points you have visited while out on site.

The WCIS provides functionality to import a .shp or .gpx file and create an activity polygon from the imported shape.

.gpx and .shp files can also be imported from your local systems using the Data Importer Application. This could be useful where you have existing shapes in your own GPS system that you wish to use as the basis for activities in the WCIS.

See Data Importer Application for guidance on importing data 

Mobile Application

The shape of an activity can be captured on-site using the Mobile Application. The Mobile Application offers two key methods for defining the shape of an activity:

Path TrackingPath tracking involves using the Mobile Application’s tracking function to periodically note your geo-location and record a point. When you decide to stop tracking the points captured will form a polygon that defines the extent of the activity. This could be useful where you are flying a helicopter over an area, or for ground based crews who would travel around the extent of a controlled area. It could also be an easy way to form a crude draft shape that can be later refined back in the office.
Manual creationThe manual create function in the Mobile Application allows users to draw the boundaries of the activity by clicking points on the map to add vertices. When finished the points will connect and create a polygon shape.

See Mobile Application for guidance on creating data 

The Mobile Application can be downloaded for free from the App Store for Apple products or the Play Store for Android products.

Pen and Paper (Data Maintenance Application)

It may be most practical to make note of the activities extent on paper, either by drawing on a map or describing in a notebook where the boundaries geographically lie.

The Data Maintenance Application provides functionality for a user back in the office to interpret your hand drawn notes/maps and create an activity polygon. This would be done using the create function.

See Data Maintenance Application for guidance on creating data

The WCIS also provides a function to upload a scanned map, align it to the topo basemap and convert the hand drawn extents into an activity feature

See Data Maintenance Application for guidance on using plans 

How do I record the attributes of an activity?

As detailed above we need to describe our activities by entering a common set of attributes. There are two methods available to record the attributes of an activity

Pen and paper (Data Maintenance Application)

Similar to recording the extent of an activity, it may be most practical to simply record the activity attributes using pen and paper. The notes you have taken would then be handed to someone back in the office and entered into the WCIS using the activity web form that appears after creating an activity shape via the create function.

See Data Maintenance Application for guidance on creating data

Mobile Application

The Mobile Application provides functionality to record the activity attributes via an e-form after you have created a shape via the manual create or path tracking functions. In doing so you can directly enter the activity attributes, while on-site, without needing to note down on paper.

See Mobile Application for guidance on creating data

Activity attributes

The table below provides a description of each activity field and how to go about collecting the data point.

Field NameDescription
TypeChoose either survey or control to indicate the type of activity you are undertaking.
Choose Survey if you are undertaking an operation to explore and discover infestations, without the purpose of applying control
Choose Control if you are undertaking an operation to control an infestation, such as a boom spray, or basal barking operation.
If you are carrying out a search and destroy operation, which will have elements of survey and control, then report the activity as control.
MethodChoose whether the activity has been carried out via an aerial operation or ground operation.
For example, choose Aerial where the crew has been applying control via a helicopter or conducting an aerial photography survey via a drone. Choose Ground where the crew is applying control on foot e.g. via a burning or chainsaw operation.
TechniqueChoose the technique that was used to control the infestation. This field will only appear when you have selected Control as the Type. The options will change depending on whether you have entered Aerial or Ground in the Method field.
VolumeWhen applicable enter the total volume of chemicals used
Lead AgencyUse the drop down box to choose the organisation that has commissioned the operation.
If the organisation does not appear on the list please enter “Land Information New Zealand” and contact your regional champion for the Wilding Conifer Information System to get the organisation added.
ContractorEnter the name of the contractor organisation conducting the activity. If the lead agency is carrying out the activity themselves, i.e. without the involvement of a contractor, then enter the lead agencies name into the Contractor field
Start DateEnter the date that the activity started
End DateEnter the date that the activity was completed
Total Team Hours
Enter the total number of man hours required to complete the activity. Where multiple people were involved at the same time then add the hours for each person.
CostEnter the cost of the activity funded by the National Wilding Conifer Control Programme.

 


This includes all transport, wages, materials, chemicals and any other expense incurred as part of the control or survey operation
CommentsEnter any additional comments as required

 

Linking activities to infestations

When an activity is created it will overlap with one or more infestations. The user must make sure that the activity has been associated to the correct infestations. This is done in the Data Maintenance Application by clicking on the related tab when with the activity selected.

See Data Maintenance Application for guidance on using the related records function

Chemicals

Users may wish to add the chemicals that were used during the activity. This is done in the Data Maintenance Application by clicking on the related tab when with the activity selected.

Review the Related Records section of the Data Maintenance Application guide for instructions on how to add chemicals to an activity.

See Data Maintenance Application for guidance on adding chemicals
