TUMap

A small application showing the capabilities of modern Remote Sensing technologies. Short explanations of the queryable layers are beneath the map. Don't be shy and try!

Layer

This layer shows the surface of planet earth in true color as you could see it from the moon. Note that the most recent images from the Sentinel 2 Mission by the Copernicus Program of ESA are used where the maximum cloud coverage is below 20%. The highest queryable resolution is 10m per pixel.

The image shows the Betsiboka River after the rainy season in Madagaskar. The deep red color is something very special in the world. It is caused by the sediments being washed out by the floods and spread into the sea.

This layer shows the surface of planet earth in a mixture of visible light and the infrared spectrum. Note that the most recent images from the Sentinel 2 Mission by the Copernicus Program of ESA are used where the maximum cloud coverage is below 20%. The highest queryable resolution is 20/10m per pixel.

The images shows the Hambach coal mine in Germany. Minerals and base materials are even better distinguishable by their infrared than their visible spectras. For example, coal shows a bloody-red appearance as seen here.

This layer shows the surface vegetation of planet earth visualized by a green-white colormap. The larger the Normalized Difference Vegetation Index (NDVI), the greener/whiter the pixels are and, accordingly, the vegetative growth. For this index, infrared and visible red are combined for the assessment of our planets vegetation. Note that the most recent measurements from the Sentinel 2 Mission by the Copernicus Program of ESA are used where the maximum cloud coverage is below 20%. The highest queryable resolution is 10m per pixel.

The image shows the Okavango Delta in the northern part of Botswana after the rainy season. If you look at the NDVI over the year, you could see the inland delta "breathe" in the rhythm of the rain.

This layer shows the surface of planet earth in true color whereas snow or frozen areas are visualized by cyan color. It is possible that clouds or salty soil look cyan (or metallic) as well. This visualization is based on several weighted infrared bands and visible light which are combined in a similar manner as for the NDVI or the BurnME layers. Note that the most recent measurements from the Sentinel 2 Mission by the Copernicus Program of ESA are used where the maximum cloud coverage is below 20%. The highest queryable resolution is 10m per pixel.

The image shows the snow coverage near the Zugspitze in early summer 2019. The winter before has been very snowy, resulting in all-time high measurements at the highest mountain in Germany. Unfortunately, several hikers and mountaineers died due to the unusual situation: they were not properly informed about the snow conditions.

This layer shows the surface of planet earth whereas fires, trouble spots or very hot areas in general are visualized by deep red color. Similar to the NDVI or SnowME layers, the calculation is based on several weighted infrared bands and visible light. Note that the most recent measurements from the Sentinel 2 Mission by the Copernicus Program of ESA are used where the maximum cloud coverage is below 20%. The highest queryable resolution is 10m per pixel.

The image shows a trouble spot of the large-scale forest fires all over Siberia in summer 2021. Though, trouble spot is probably the wrong term: the width of the burn blister is 15km.
