Hi everyone,
I've developed a function to validate species distribution data within a data frame against known lists of mammal species and geographic coordinates. The function produces a data frame that includes validation results and additional information. This tool is invaluable for verifying datasets, confirming species presence in Colombia, and pinpointing their departmental records based on coordinates.
The output includes a column indicating the validation result for each occurrence. If a record falls within the ocean, the validator flags it as "sea." Additionally, it identifies coordinates that require manual verification due to overlapping boundaries or being outside defined limits.
Please note that the geographic file of Colombia included in the package may contain topological errors, leading the validator to label some records as "for manual review." Therefore, I've included the latest vector file of Colombia from Igac (2024 version) in this folder for optional use. Furthermore, I've integrated an Ocean layer to validate marine species records effectively.
I hope this will be useful. Can you test if it works, or if you need more information?
Regards,
Cristian
