title: habitatmap_terr: the interpreted, terrestrial part of habitatmap_stdized

description: The data source habitatmap_terr is the further interpreted, terrestrial part of 'habitatmap_stdized' (which, in turn, was derived from the raw data source 'habitatmap'). It is a GeoPackage that contains:



	

	
habitatmap_terr_polygons: a spatial polygon layer in the Belgian Lambert 72 coordinate reference system (EPSG-code 31370);
	
	

	
habitatmap_terr_types: a table with the types that occur in each polygon.
	



This version of habitatmap_terr was derived from version 'habitatmap_stdized_2018_v2' as follows:



	

	
it excludes all polygons that are most probably aquatic habitat or RIB. These are the polygons for which all habitat or RIB types are aquatic. In the process, a distinction was also made between 2190_a and 2190_overig. There is no exclusion of aquatic types when these coexist with terrestrial types in the same polygon;
	
	

	
it excludes types which most probably are no habitat or RIB at all. Those are the types where code_orig contains "bos" or is equal to "6510,gh" or "9120,gh";
	
	

	
it translates several main type codes into a corresponding subtype which they almost always represent: 6410 -> 6410_mo, 6430 -> 6430_hf, 6510 -> 6510_hu, 7140 -> 7140_meso, 9130 -> 9130_end;
	
	

	
it distinguishes types rbbhfl and rbbhf.
	



See R-code in the GitHub repository 'n2khab-preprocessing' at commit ce1393b for its creation from the habitatmap_stdized data source.

description: This version is almost identical to version habitatmap_terr_2020_v1. The only difference is that the combination of polygon_id, type and certain in the habitatmap_terr_types table has been made unique, so that they can serve as a primary key in this table. Fixing this had consequences in just one polygon.

title: Deep Learning Based Rust and Smut Detector for Wheat Plants

description: This dataset consists of high-resolution images of wheat plants collected from Pakistan for a research project. The dataset includes images of both healthy wheat plants and wheat affected by four common diseases: Common Bunt, Loose Smut, Stem Rust, and Brown Rust. All images were captured under real in-field conditions using high-resolution cameras and subsequently resized to ensure compatibility with machine learning models. This dataset is valuable for researchers working on plant disease detection, computer vision applications in agriculture, and machine learning-based classification models.
