💧 ESDM ArtesIS Groundwater Maps Downloader

Download the groundwater maps of Indonesia's ArtesIS portal (Badan Geologi, Kementerian ESDM) as ready-to-use GIS files: groundwater basins (Cekungan Air Tanah, CAT), aquifer productivity (Produktivitas Akuifer), groundwater availability (Ketersediaan Air Tanah), conservation zones and more, for the provinces or area you choose. Every map comes as a zipped Shapefile and a GeoJSON file with the portal's own attributes and catalogue details (scale, data date, producer). No login needed; $0.001 per file plus $0.43 per 1,000 map features on the Free plan, platform usage included.

✨ Why use ESDM ArtesIS Groundwater Maps Downloader?

  • 🗺️ Real GIS files, not pictures — polygons with every attribute the portal holds (aquifer class, discharge, basin name, recharge figures, conservation zone...), in WGS 84, ready for QGIS, ArcGIS, Python or a web map.
  • 📍 Per province or your own area — one file per map and province (Sumatera Selatan, Jawa Barat, DKI Jakarta...), a custom longitude/latitude box, or the whole of Indonesia in one file.
  • 💧 All groundwater themes in one run — basins, aquifer productivity, groundwater availability and conservation zones, plus river basin territories, soft soil, problematic claystone, land suitability, liquefaction and karst areas.
  • 🧾 Catalogue details on every file — map scale, data date and data producer from the portal's data catalogue, feature counts and a summary of the classes in the file.
  • 🔗 Shareable download links — each file gets a link that opens without an account for 30 days.
  • ⚡ Fast — a province with three groundwater maps takes about a minute.

🎯 Use cases

  • 🚰 Water supply and drilling plans — check aquifer productivity and groundwater availability before siting a well.
  • 🏗️ Spatial planning and permits — overlay groundwater basins (CAT) and conservation zones with land parcels or project sites.
  • 🎓 Research and theses — hydrogeology, land-use and disaster studies with the official national maps as layers.
  • 🌱 Environmental assessments (AMDAL / UKL-UPL) — groundwater, soft soil, liquefaction and karst constraints for a site.
  • 🤖 Automation — refresh the layers on a schedule or pull them through the API into your own GIS pipeline.

🚀 How to use

  1. Pick the Maps you need (by default: groundwater basins, aquifer productivity and groundwater availability).
  2. Type one or more Provinces (Indonesian or English names and short forms such as Sumsel, Jabar, NTB work), or set an Area box, or leave both empty for all of Indonesia.
  3. Choose the File formats (Shapefile and GeoJSON by default) and click Start.
  4. Open the Download link of each row, or export the rows as JSON, CSV or Excel.

💰 Pricing

You pay per map file and per map feature (one polygon or area record) in the files you get: $0.001 per file plus $0.000425 per feature on the Free plan ($0.43 per 1,000 features), with lower feature prices on paid plans. Platform usage is included. Examples from test runs: the three groundwater maps of Sumatera Selatan (10 basins, 265 aquifer areas, 27 availability areas) ≈ $0.13; the groundwater availability map of all Indonesia (22,062 features) ≈ $9.40. Files with no features in your region are not saved and cost nothing.

❓ FAQ

Is it legal? The maps are public data of Badan Geologi, Kementerian ESDM, shown to everyone on the ArtesIS portal. Cite the source when you publish them.

Do I need a login or proxy? No. The default Scrape.ly datacenter proxy works for the portal.

How precise are the polygons? Groundwater basins (CAT) keep the portal's original geometry. The other maps come from the portal's vector map tiles at their most detailed zoom: about 19 m for aquifer productivity and conservation zones, about 2.4 m for groundwater availability, land suitability and liquefaction (precisionMeters on each row). That is finer than the 1:100,000 and 1:250,000 scales the maps were made for.

What does a province file cover? Every map feature with some area inside the province (or your area box), kept whole: features that cross the border are not cut, so they reach into the neighbour. Basins (CAT) are the basins the portal lists for the province plus basins lying at least 10% inside it, which covers the new Papua provinces too.

Why do some rows have no data date? The portal's catalogue has entries only for some maps (for example none for groundwater availability); those fields stay empty.

Can I schedule it or use the API? Yes, like any Scrape.ly Actor: schedules, API, webhooks and integrations.

⚠️ Limits

  • Only what the ArtesIS portal publishes: some maps cover part of Indonesia only (conservation zones: Java; liquefaction: selected regions).
  • Features that cross a map-tile edge are joined back together; where the portal's tiles do not line up exactly, a feature can stay in a few parts.
  • Groundwater availability, soft soil and claystone maps hold many areas with identical attributes; areas with the same attributes are saved as one multi-part feature.
  • The portal's reference images (geology, geomorphology and earthquake hazard posters) and its permit and monitoring-well data are not included.
  • Whole-country files of the most detailed maps (groundwater availability, land suitability) are large (groundwater availability: about 47 MB zipped Shapefile, its GeoJSON is saved zipped) and need 2 GB of run memory or more; a single file must stay under 95 MB, so very large areas may need to be split into provinces.
  • Download links work for 30 days; download the files you want to keep.
