TerraClass x MapBiomas: Comparative assessment of legend and mapping agreement analysis
نویسندگان
چکیده
In this work, we evaluated the agreement between land cover maps generated by TerraClass and MapBiomas projects for Pará state and, more specifically: (1) describe the legends based on an international classification system, (2) analyze the differences among classes and (3) test PostGIS Raster from PostgreSQL database to work with classification products. The classifications were compared pixel by pixel and the evaluation was performed based on confusion matrices. The agreement between them was 84.40%. The different methodologies adopted by the two projects generate significant disagreements in class identification, so using both maps together as complementary is not recommended for land use and cover change analyzes.

Qualitative Evaluation of Digital Hand X-rays is Not a Reliable Method to Assess Bone Mineral Density
Object: The gold standard for evaluating bone mineral density is dual energy x-ray absorptiometry (DEXA). Prior studies have shown poor reliability using analog wrist X-rays in diagnosing osteoporosis. Our goal was to investigate if there was improved diagnostic value to visual assessment of digital hand X-rays in osteoporosis screening. We hypothesized that similar to analog counterparts, dig...
متن کاملEvaluation of students' clinical skills: Agreement of self-assessment and clinical teacher assessment scores
Abstract Introduction: The most essential part of any training program is evaluation, because by doing so, the shortcomings of the program can be realized and dealt with. Clinical evaluation of students is one of the fundamental challenges in clinical nursing education. Nowadays, self-evaluation is proposed as a useful method along with student evaluation by teacher. Objective: This stu...
متن کاملNonexpansive mappings on complex C*-algebras and their fixed points
A normed space $mathfrak{X}$ is said to have the fixed point property, if for each nonexpansive mapping $T : E longrightarrow E $ on a nonempty bounded closed convex subset $ E $ of $ mathfrak{X} $ has a fixed point. In this paper, we first show that if $ X $ is a locally compact Hausdorff space then the following are equivalent: (i) $X$ is infinite set, (ii) $C_0(X)$ is infinite dimensional, (...
متن کاملAssessment of Guinea Savanna River system to evaluate water quality and water monitoring networks
The analysis of changes in water quality in a monitoring network system is important because the sources of pollution vary in time and space. This study utilized analysis of the water quality index calculation, hierarchical cluster analysis, and mapping. This was achieved by assessing the water quality parameters of the samples collected from Galma River in Zaria, Northwestern Nigeria in wet an...
متن کاملOn invariant sets topology
In this paper, we introduce and study a new topology related to a self mapping on a nonempty set.Let X be a nonempty set and let f be a self mapping on X. Then the set of all invariant subsets ofX related to f, i.e. f := fA X : f(A) Ag P(X) is a topology on X. Among other things,we nd the smallest open sets contains a point x 2 X. Moreover, we find the relations between fand To f . For insta...
