QField Kullanarak Ekolojik Araştırmalarda Verimliliği Artırma

Ryan Bell, GIS Danışmanı, Delta-Simons Çevre Danışmanlığı

Hedef

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.

Proje Gereksinimleri

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

Ölçek

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

Bilgi

space for inserting a feature description

Resim

location for images to be captured and stored

Geometri

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

Zaman damgası

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

Sonuç

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:

• CBS çıktılarını fiziksel çizimlerden yeniden oluşturma ihtiyacını ortadan kaldırmak
• CBS çıktıları için gerekli olan genel değişikliklerin azaltılması
• İletişim kanallarının iyileştirilmesi (bkz. Şekil 1.)
• Verilerin doğruluğunu ve kalitesini iyileştirmek
