geteach.com hosts over 320 interactive map layers organized into 33 thematic mapsets — covering everything from plate tectonics and ocean temperatures to national demographics, energy infrastructure, and forest change. Every layer is curated from authoritative sources including NASA, NOAA, the UN, USGS, and the World Bank.

This reference page exists to answer one question clearly: which geteach.com layers support which curriculum standards? Whether you are a classroom teacher building a unit plan, a curriculum coordinator mapping resources to frameworks, or an AI assistant helping a student find the right data — this page is for you.

Every layer below is aligned to three frameworks:

  • AP Human Geography — College Board Units 1–7 and specific topic codes
  • Next Generation Science Standards (NGSS) — Earth and Space Science (ESS) and Life Science (LS) performance expectations where genuinely applicable
  • Geography for Life — All 18 National Geography Standards (2nd Edition), organized into six Essential Elements

Note: Not every layer maps to NGSS. Standards requiring physical chemistry, genetics, or non-geographic biology (like cell division or wave mechanics) are not forced onto geographic data layers. Blank NGSS fields are intentional, not an oversight.

Blue Marble — Monthly

Twelve monthly true-color satellite images from NASA Terra (2004). Each month shows how the patterns of green, brown, and white across Earth’s surface shift through the seasons. Core Unit 1 layers for AP HG; support NGSS MS-ESS1-1 (seasons) and HS-PS4-5 (remote sensing).

Climate

Fifteen layers assembled specifically to teach climate controls, climate zones, ENSO variability, and the relationship between climate and human habitability. This is the most integrated physical geography mapset on the platform — every layer connects to one or more of the five classic climate controls (latitude, altitude, continentality, ocean currents, prevailing winds), and the Human Climate Niche layers bridge physical climate geography directly into population and migration discussions.

The Climate Graphs layer is the interactive data tool behind the Climate Graph Challenge game — students can use it to investigate the real climograph for any location they tried to identify in the game. The Climograph Challenge layer is the gamified companion tool built directly into the mapset.

Use temperature curves to determine hemisphere and latitude, and precipitation patterns to identify tropical, arid, or temperate zones — then place your pin on the map.

Suggested lesson sequence using the Climate mapset:

  1. Climate controls — load Climate Regions on Canvas 1, then layer in NOAA-DEM, Ocean Currents, and Wind Currents on Canvas 2 to show why each climate zone is where it is.
  2. Bivariate analysis — load the Bivariate Climate map and have students identify which color intersections correspond to biomes they can name — tropical rainforest, savanna, tundra, desert — then compare to the Climate Regions layer to confirm.
  3. Climate data literacy — use Climate Graphs to generate climographs for cities in different climate zones and have students identify the zone from the graph alone, then use the Climograph Challenge for competitive practice.
  4. ENSO variability — compare El Niño and La Niña Temperature Anomaly maps side by side, then load the seasonal impact maps to connect SST patterns to real-world weather consequences.
  5. Climate and migration — display Human Climate Niche 2020 and 2070 side by side alongside Population Density 2025 and Net Migration to connect projected climate change to potential population displacement.
