The goal of this lab is to give you the foundations for working with IDRISI, the image processing program that you will be using in all of your subsequent labs, and for your final project. As such, this is a long lab 6 hours is an estimate for the time required to complete this lab. However, remember that with this experience you can put down in your resume that you have some working knowledge of image processing. Given the length of this lab, you should budget your time accordingly. As a goal, you should finish Part 1, Exercises 1. In the second week, complete the rest of Part 1, Exercises 1.

File maintenace : Interfaz para mantenimiento de archivos como renombrar, eliminar, etc Una vez que tenemos configurado el entorno de trabajo, vamos a empezar a trabajar ya en el entorno de trabajo de Idrisi. Figura 2. Figura 4. Abre la imagen desde DISPLAY Launcher con la paleta "Idrisi 16", el resultado de esta paleta no es el satisfactorio de cara a posibles presentaciones, con lo que crearemos una paleta personalizada.

Ventana de rango de autoescalado, utilizado para autoescalar los niveles de color en la imagen a la que le apliquemos la paleta. Las opciones que tiene la ventana de Symbol Workshop como podemos observar en la figura 6 son: Figura 6: Ventana de trabajo de Symbol.

Como no sabemos con exactitud los niveles que tenemos en el vectorial utilizaremos como intervalo de 0 a Icono "Cursor Query" : Sirve para obtener el valor de un atributo para un pixel en concreto.

Pinchad en el icono del cursor "Query Icon". Figura Mapa de altitudes discretizadas a 8 intervalos de 25m cada uno. Figura Mapa booleano cuyo valor 1 o verdadero representa a las altitudes iguales o mayores a 1. EL valor 0 falso representa las altitudes menores a metros que no nos interesaban.

Realicemos ahora un ejercicio sencillo en donde intervengan varias condiciones. Las preguntas que intentaremos resolver son las siguientes: 1.

Week of February 11 th you have two weeks for this lab. Hand in the printout of your Landsat composite image. Right click on the existing pathname which might be C: Read the first few pages about projects and working folders. To do this, use the Print option on the composer menu and ensure that you send your image to the appropriate colour printer. Remote Sensing Geob Using Landsat data of the Fraser Valley For this part of the lab you will take what you learned manuao the tutorials, and apply it to a local dataset: The differences between raster and vector data are discussed throughout the exercises, although Exercises and in particular cover the material you should use in your answer to this question. We will have some hard copies of the relevant sections of the IDRISI tutorial available for you in the lab a scanned copy of the relevant sections here. The goal of this lab is to give you the foundations for working with IDRISI, the image processing program that you will be using in all of your subsequent labs, and for your final project.

Indeed, no other type of sotware can provide this. OVERLAY performs nine diferent operations between two images including add, subtract, multiply, divide, normalized ratio, exponentiate, minimize, maximize, and cover. HISTO provides a graphic or numeric frequency histogram and statistics of the cell values within an image. AREA calculates the area in a variety of units of each class in an image. Image Calculator can evaluate models such as this vulnerability mapping analysis using fuzzy criteria in West Africa.
