1935 Hydrographic Map of the IJsselmeer Area, Georeferenced

A historical depth map of the IJsselmeer area created by the Dienst der Zuiderzeewerken. The map likely dates from around 1935 and depicts the Wieringermeer reclamation, the Noordoostpolder, and the Afsluitdijk. The Cultural Heritage Agency of the Netherlands holds the original analogue map, and the provided scan is georeferenced to the Dutch National Triangle System (RD).

Use Cases

• Analyzing historical coastal and lake depth changes based on the bathymetric measurements.
• Studying the progression of Dutch land reclamation projects like the Wieringermeer and Noordoostpolder.
• Georectifying other historical maps of the region using the provided RD coordinate system.
• Visualizing the early 20th-century landscape prior to major modern developments.

Strengths

• The map is georeferenced to the National Triangle System (RD), enabling GIS integration.
• It captures a specific historical period (circa 1935) during major Dutch engineering works.
• The provenance is documented, citing the Directorate of the Wieringermeer and the Cultural Heritage Agency.

Limitations

• Column-level documentation is absent; the exact data attributes of the georeferenced file are unknown.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
• The description metadata is limited; actual raster data quality requires manual inspection after download.
