Book Reviews: Additional Resources

Summary

This article reviews five new maps of the Atlas of Australian Resources released by the Department of National Development, covering croplands, geology, immigration, mineral industry, and manufacturing. The croplands sheet includes four sub-maps on wheat acreage, yield, and other crops, highlighting post-war trends of reduced total wheat acreage but increased per-acre yields. The geology map at 1:6,000,000 scale reveals three physiographic regions linked to ancient shields. While praising the successful color selection, the author critiques three inappropriate color choices in the croplands sheet and the geology map's reliance solely on hue contrast without value differences, suggesting superimposed symbols and color variation to enhance legibility.
