    pre-printWe introduce several useful utilities in development for the creation and analysis of real wildland fire simulations using WRF and SFIRE. These utilities exist as standalone programs and scripts as well as extensions to other well known software. Python web scrapers automate the process of downloading and preprocessing atmospheric and surface data from common sources. Other scripts simplify the domain setup by creating parameter files automatically. Integration with Google Earth allows users to explore the simulation in a 3D environment along with real surface imagery. Postprocessing scripts provide the user with a number of output data formats compatible with many commonly used visualization suites allowing for the creation of high quality 3D renderings. As a whole, these improvements build toward a unified web application that brings a sophisticated wildland fire modeling environment to scientists and users alike

    This paper describes the development of a hardware and software tool for analysis of vegetation cover using remote sensing techniques. Begins with a study of the interaction of electromagnetic waves in the leaves of plants on the single and multiple plate models for the spectrum of visible and infrared, which allows using an application developed in Python found the spectral signature of coverage according to parameters of the leaves (known as an inversion model), which accounts for an approximation of what may occur with the reflectance of the surface of the leaves. The development of a system for acquiring and processing images in the visible and near infrared bands for use in precision agriculture through an unmanned aerial vehicle UAV is also explained.En este documento se presenta el desarrollo de una herramienta de hardware y software para análisis de coberturas vegetales mediante técnicas de sensado remoto. Inicia con un estudio de la interacción de las ondas electromagnéticas en las hojas de las plantas según el modelo de placa sencilla y múltiple para el espectro del visible y el infrarrojo, que permite mediante una aplicación desarrollada en Python encontrar la firma espectral de coberturas según parámetros de las hojas (conocido como un modelo de inversión), que da cuenta de una aproximación de lo que puede ocurrir con la reflectancia de la superficie de las hojas. Se explica también el desarrollo de un sistema de adquisición y procesamiento de imágenes en las bandas del visible e infrarrojo cercano para su uso en agricultura de precisión mediante un vehículo aéreo no tripulado VANT
