Mellorando Eficiencias en Mostraxe Ecolóxica utilizando QField

Por Ryan Bell, Consultor SIX, Consultoría Ambiental Delta-Simons

Obxectivo

To conduct ecological surveying more efficiently than has been previously achieved through traditional non-digital techniques, using QField as a medium for standardised and flexible field data collection.

Necesidades do Proxecto

To facilitate effective field work, regular consultation with the Ecology team is required to ensure that QField projects are prepared appropriately. Firstly, basemaps comprising aerial imagery and proposed development plans are prepared by georeferencing and constructing pyramids in QGIS. Point, line and polygon vector layers are then created to support digitisation and associated data collection. Using a range of widgets, attribute fields are customised to meet the requirements of the Ecology team. These include:

Estilo

drop-down list of selectable styles tailored for conducting ecological surveys

Escala

drop-down list of selectable scales for point and line feature

Información

space for inserting a feature description

Imaxe

location for images to be captured and stored

Xeometría

contains self-populated geometry values, e.g. area, perimeter, length

Data e hora

records the time and date that a feature was created/last modified

Resultado

Delta-Simons are saving approximately 40% of the time previously consumed by traditional ecological field data collection. QField has significantly improved the ecological surveying workflow by:

  • Eliminar a necesidade de recrear saídas SIX de debuxos físicos
  • Reducir as correccións totais necesarias para os resultados SIX
  • Mellorando as canles de comunicación (ver Figura 1.)
  • Mellorando a precisión e calidade dos datos
