Îmbunătățirea Eficienței în Cercetarea Ecologică folosind QField

Obiectiv

Efectuarea cercetării ecologice în teren, mult mai eficient decât prin intermediul tehnicilor tradiționale non-digitale, folosind QField ca mediu de colectare standardizată și flexibilă a datelor.

Cerințele Proiectului

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:

Stil

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

Scale

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

Info

space for inserting a feature description

Imagine

location for images to be captured and stored

Geometrie

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

Amprentă temporală

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

Rezultat

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:

• Removing the need to recreate GIS outputs from physical drawings
• Reducing the overall amendments required for GIS outputs
• Îmbunătățirea canalelor de comunicare (v. Figura 1.)
• Îmbunătățirea preciziei și calității datelor
