Hands-on Activity: The Dirty Water Project: Design-Build-Test

Jan 23, · In this hands-on activity, students investigate different methods—aeration and filtering—for removing pollutants from water. Working in teams, they design, build and test their own water filters—essentially conducting their own "dirty water projects." A guiding data collection worksheet is provided.

The Many Band Combinations of Landsat 8 - L3Harris Geospatial

This band combination is as close to "true color" as you can get with a Landsat OLI image. One unfortunate drawback with this band combination is Because this band combination makes use of both of the SWIR bands aboard Landsat 8, the image is much more crisp than band combinations

Blood Diamonds | Environmental Impact

Diamond miners have re-routed rivers and constructed dams to expose riverbeds for mining, with disastrous effects on fish and wildlife. In extreme cases, diamond mining can cause entire ecosystems to collapse. Diamond miners in the Kono district of eastern Sierra Leone have left behind thousands of abandoned mining pits.

What is remote sensing and what is it used for?

Landsat 9 will carry the same instruments that are on the Landsat 8 satellite but with some improvements: Operational Land Imager-2 (OLI-2) for reflective band data. Thermal Infrared Sensor-2 (TIRS-2) for the thermal infrared bands. OLI-2 will have a slightly improved signal-to-noise ratio over Landsat 8's OLI. Landsat 9’s TIRS-2 is a Class-B

Rivers, Streams, and Creeks - USGS

Rivers flow through valleys in the landscape with ridges of higher land separating the valleys. The area of land between ridges that collects precipitation is a watershed or drainage basin. Most, but not all, precipitation that falls in a watershed runs off directly into rivers - part of it soaks into the ground to recharge groundwater aquifers
