Export Geospatial Data and Regional Metrics to MongoDB

Downloads and processes geospatial data from different countries, harmonizes their structures, applies currency conversions to regional time series metrics, and exports all data to MongoDB collections with appropriate indexing.

Usage

export_geos(package = "coasts")

Arguments

package

Name of the package whose `inst/conf.yml` to read. Defaults to `"coasts"`. Pass your own package name when calling from a downstream package with a compatible configuration.

Value

None (invisible). Creates and uploads data to three MongoDB collections: - Regional boundary geometries (with 2dsphere index) - Regional time series metrics (currency-converted) - PDS track grid summaries

Details

This function performs several key operations:

**Geospatial Data Processing:** 1. Downloads GeoJSON files for Kenya, Mozambique and Zanzibar regions from cloud storage 2. Reads and combines the regional boundary data into a single dataset 3. Uploads combined geospatial data to MongoDB with 2dsphere indexing for spatial queries

**Regional Metrics Processing:** 4. Downloads monthly summary parquet files for both countries from cloud storage 5. Applies currency conversion factors to monetary metrics 6. Converts the following monetary fields: mean_rpue, mean_rpua, mean_price_kg 7. Uploads regional metrics to MongoDB without geospatial indexing

**PDS Track Grid Processing:** 8. Downloads PDS track grid summaries from cloud storage 9. Uploads grid summaries to a separate MongoDB collection

The function requires appropriate configuration parameters for cloud storage access and MongoDB connection details, typically loaded via `read_config()`.
