Enhancement: Allow fieldShape to Create Plot Files Without Mosaic Layer

[qmwnebrv]

There are situations where it is necessary to create a field shapefile before a mosaic is available. Sometimes, users have the GPS coordinates (collected via RTK) of the trial corners but do not yet have a processed mosaic. While the shapefile might not require the accuracy necessary for UAV plot analysis, it still needs to contain georeferenced plot polygons.
Problem Statement:

The fieldShape function currently requires a mosaic layer to work. However, it could be useful to allow users to create the plot file without the mosaic layer, either by using:

• GPS coordinates alone (with a warning about potential lower accuracy).
• A base map instead of a UAV-derived mosaic.

Proposed Solution:

Enhancement:
Add an option to the fieldShape function to enable shapefile creation without requiring a mosaic layer.

• Option A: Use only GPS coordinates from another layer (with 4 points representing the trial corner)
• Option B: Use a base map rather than a UAV-derived mosaic.

Warnings:
Include a warning to users that accuracy might be lower without a UAV-derived mosaic.
Provide guidance on improving accuracy if needed (i.e by using a proper georefecenced mosaic)

Additional Context:
This enhancement would help users who need georeferenced plot polygons quickly but do not have a UAV mosaic available. It would expand the functionality of the fieldShape function and increase its flexibility for use in applications other than UAV data processing

Hey there, Thanks for your suggestion ... Actually, we already uploaded the function to allow: (1) uploading four-points-shapefile (e.g., GPS) (2) no need of mosaic (it is necessary installing QuickMapService - https://plugins.qgis.org/plugins/quick_map_services/) For more information go to: https://github.com/filipematias23/FIELDimageR-QGIS/tree/main?tab=readme-ov-file#p3 Attention: Upload the functions of FIELDimageR on your QGIS to use the latest version. Hope it helps...! Best, FIELDimageR Em qua., 8 de mai. de 2024 às 21:45, qmwnebrv ***@***.***> escreveu:
