A person whose legal rights are being used without authority may opt to litigate immediately but a cease and desist letter can achieve several tactical purposes. First of all, it may stop the illegal misuse of legal rights and if not much damages have been caused, there may then be no need to litigate.
âLandsat is an invaluable resource for developing these high resolution maps. Without the Landsat imagery we would not have the spectral information needed to decompose urban landscapes into Local Climate Zone types. Hence the data is at the heart of the project and it is the most critical pieceâwithout Landsat there is no project.â. âAn engineering degree opens many doors.
The images are composed of thousands of pixels that the satellite scanned into rows and columns. The satellite gathers a group of rows into a computer file. This file covers an area of Earth known as a scene. The scene size varies depending on the sensor. Sensors on Landsat, the US satellite series, has scenes about 185 km (115 miles) on each side. The illustration shows a Landsat scene coverage for the San Francisco Bay Area. Scenes for other commonly-used sensors range in size from 60 km to 2200 km. A scene of Landsat can have over 6000 rows and columns of pixels. You usually purchase satellite imagery by the scene. Scenes can cost anywhere from $50 for poorer-resolution, public-domain data to over $5000 for higher-quality scenes.
