Maps for survey design and source review

A map should help answer the question in the discussion. In Maluku, geography helps organize coverage across islands and investigate livelihood connections. In Nepal, district boundaries help review the coverage and geographic correspondence of source documents. These applications use small, documented geographic extracts alongside the survey materials.

Maluku: organize geographic coverage

The Tanimbar archipelago gives a practical reason to distinguish residence, livelihood activity and travel. A household may live in one settlement, land a catch elsewhere and sell through a different market. Plan the listing and field itinerary around those relationships, including season and transport mode.

Use the Indonesia · Maluku survey guide to connect this geography with household, livelihood and mobility questions. Administrative polygons establish reporting units. Settlement lists, field verification and resource-use mapping establish the relevant survey frame and connections.

Nepal: inspect the coverage of source records

This map joins the historical district finding aid to district geometry. Its categories describe entries in that index. They do not measure population, poverty or the present availability of statistics. Select a district to inspect its record before following the Nepal source discussion.

The Rukum and Nawalparasi successor districts illustrate why a map join needs an edition check. Two present-day districts can refer to one older combined-area document. Keep that older geographic unit intact until a defensible correspondence supports allocation. The Nepal guide explains the implications for comparison.

From a mapped relationship to a measure

An overlay becomes useful when its numerator, denominator and interpretation are clear. The interactive parcel example shows how changing a proposed restriction changes the proportion of land used within it. The schematic uses metre dimensions and synthetic parcels; its calculation is separate from the geographic context maps above.

For an access analysis, use routes, transport modes, seasonal conditions and destinations. For land exposure, use the versioned project footprint and verified use areas. The geospatial assessment method connects these operations with field evidence and decisions.

Publish a small, reproducible view

The maps here render directly in the notebook with MapLibre. Their reviewed geographic extracts are delivered with the article; selecting or navigating them starts no analytical job and requests no external basemap. The parcel example calculates its intersections in JavaScript. Legends, linked details and tables provide accompanying accounts of the map's content.

Keep large originals in the managed archive and publish a compact derived view for the article's question. Use D3 or Observable Plot for analytical figures, MapLibre for interactive geographic layers, PMTiles for larger tiled vector views and Cloud Optimized GeoTIFF for raster subsets where appropriate. Recompute a derived output when its inputs or analytical assumptions change.

The same layer can later support an OpenGeo composition or a local notebook without changing its source identity, date or reuse conditions. Record these with the processing recipe and output checksum. Public maps contain approved geographic and aggregate information; managed source access continues through the citation manager and the dataset curation workflow.
