Object-Based Image Analysis (OBIA)

Object-Based Image Analysis (OBIA) is suitable for researchers, students, clinicians, laboratories, NGOs, businesses and project teams that already have remote-sensing imagery and need this specific analysis to answer a defined analytical question. A clear objective and well-documented dataset will substantially improve the usefulness of the result.

Please remove passwords from files you intend to submit, keep an untouched backup of your original data, and provide a short data dictionary explaining variable names, units, codes, missing-value conventions and any exclusions already made. Identify the target variable or task, available features, unit of observation, class labels, train/test constraints and the metric that matters most to you. Flag duplicated subjects, leakage-prone variables and any data that must remain in a held-out set. Supply coordinate reference system information, spatial extent, acquisition dates, layer descriptions and the output projection/scale you require. For raster data, include resolution and NoData conventions where known. Use original-resolution image or DICOM files rather than screenshots where possible. Provide consistent file naming, region-of-interest instructions, calibration/scale information and any labels or ground truth needed for comparison. For Object-Based Image Analysis (OBIA), also tell the analyst about any unusual coding, exclusions, transformations or prior processing that could change how this dataset should be handled.

For Object-Based Image Analysis (OBIA), provide the analysis objective, dataset or file inventory, variable/data dictionary, study or business context, desired tables/figures, required software or reporting format if any, deadline, and a note identifying any confidential or regulated information in the files.

Your analyst will review the files for structure and obvious quality issues, confirm the analytical approach for Object-Based Image Analysis (OBIA), run the appropriate object-based remote-sensing classification workflow, and return the agreed outputs. Where relevant, deliverables may include cleaned data, code, statistical tables, figures, model diagnostics, maps, annotated images or an interpretation summary.

For Object-Based Image Analysis (OBIA), only submit data you are authorised to share. Remove direct personal identifiers whenever they are not essential, and use secure transfer for clinical, genomic, financial or other sensitive information. AnalysisAfrica service providers should not be asked to fabricate, alter or selectively suppress results to reach a preferred conclusion.

The output from Object-Based Image Analysis (OBIA) should be read together with the stated assumptions, data-quality limitations and analysis plan. Statistical significance, model accuracy or algorithmic classification does not by itself prove causation or clinical validity; conclusions should remain proportionate to the design and quality of the underlying data.

Changes to variables, endpoints, inclusion criteria or requested figures after work on Object-Based Image Analysis (OBIA) has started may require re-analysis and an updated quote. If reproducibility matters, request the analysis script, software/package versions, parameter settings and a record of data-cleaning decisions as part of the deliverables.
