  • Positional Accuracy in Orbital Images of High and Medium Resolution: Case Study with Image Sensors of the Spot, Rapideye and Resourcesat Satellites
    POSITIONAL ACCURACY IN ORBITAL IMAGES OF HIGH AND MEDIUM RESOLUTION: CASE STUDY WITH IMAGE SENSORS OF THE SPOT, RAPIDEYE AND RESOURCESAT SATELLITES Moreira, N. A. P1, Felgueiras, C. A.2 e Dutra, L. V.3 1,2,3 National Institute for Space Research – INPE Mailbox 515 - 12227-010- São José dos Campos-SP, Brazil [email protected], [email protected], [email protected] Abstract The objective of this work is to evaluate and to analyze positional accuracies, through specific sample points and tracks, of remote sensing registered images acquired by sensors on board the Spot-6, RapidEye and ResourceSat-1 satellites and having, respectively, 1.5, 5 and 24 meters of resolutions. A case study is developed in areas of the Santarém and Belterra municipalities of the Brazilian Pará state. In addition of generating reports with positional accuracy information, this paper investigates the relationship between the spatial resolutions and the positional accuracies of the different digital remote sensing image sensors. High precision reference points and tracks, continuous lines, were collected in field works in order to be compared to adjust points and tracks obtained directly by manual digitalization over each considered image. Samples of points and tracks were analyzed for different positional regions of the images and a C language program was used to perform the calculations of point and track accuracies considering metrics of Euclidean distances and error areas. Accuracy reports present statistics and deterministic error measurements, such as averages, variances, standard deviations, absolute values, areas, root mean square values, etc. Such errors were evaluated from the reference and adjust data, for points and tracks, in regions of interest of the analyzed images.

  • The Contribution of Earth Observation Technologies to Monitoring Strategies of Cultural Landscapes and Sites
    The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XLII-2/W5, 2017 26th International CIPA Symposium 2017, 28 August–01 September 2017, Ottawa, Canada THE CONTRIBUTION OF EARTH OBSERVATION TECHNOLOGIES TO MONITORING STRATEGIES OF CULTURAL LANDSCAPES AND SITES B. Cuca a* a Dept. of Architecture, Built Environment and Construction Engineering, Politecnico di Milano, Via Ponzio 31, 20133 Milan, Italy – [email protected] KEY WORDS: Cultural landscapes, Earth Observation, satellite remote sensing, GIS, Cultural Heritage policy, geo-hazards ABSTRACT: Coupling of Climate change effects with management and protection of cultural and natural heritage has been brought to the attention of policy makers since several years. On the worldwide level, UNESCO has identified several phenomena as the major geo-hazards possibly induced by climate change and their possible hazardous impact to natural and cultural heritage: Hurricane, storms; Sea-level rise; Erosion; Flooding; Rainfall increase; Drought; Desertification and Rise in temperature. The same document further referrers to satellite Remote Sensing (EO) as one of the valuable tools, useful for development of “professional monitoring strategies”. More recently, other studies have highlighted on the impact of climate change effects on tourism, an economic sector related to build environment and traditionally linked to heritage. The results suggest that, in case of emergency the concrete threat could be given by the hazardous event itself; in case of ordinary administration, however, the threat seems to be a “hazardous attitude” towards cultural assets that could lead to inadequate maintenance and thus to a risk of an improper management of cultural heritage sites. This paper aims to illustrate potential benefits that advancements of Earth Observation technologies can bring to the domain of monitoring landscape heritage and to the management strategies, including practices of preventive maintenance.

  • The Earth Observer. July
    National Aeronautics and Space Administration The Earth Observer. July - August 2012. Volume 24, Issue 4. Editor’s Corner Steve Platnick obser ervth EOS Senior Project Scientist The joint NASA–U.S. Geological Survey (USGS) Landsat program celebrated a major milestone on July 23 with the 40th anniversary of the launch of the Landsat-1 mission—then known as the Earth Resources and Technology Satellite (ERTS). Landsat-1 was the first in a series of seven Landsat satellites launched to date. At least one Landsat satellite has been in operation at all times over the past four decades providing an uninter- rupted record of images of Earth’s land surface. This has allowed researchers to observe patterns of land use from space and also document how the land surface is changing with time. Numerous operational applications of Landsat data have also been developed, leading to improved management of resources and informed land use policy decisions. (The image montage at the bottom of this page shows six examples of how Landsat data has been used over the last four decades.) To commemorate the anniversary, NASA and the USGS helped organize and participated in several events on July 23. A press briefing was held over the lunch hour at the Newseum in Washington, DC, where presenta- tions included the results of a My American Landscape contest. Earlier this year NASA and the USGS sent out a press release asking Americans to describe landscape change that had impacted their lives and local areas. Of the many responses received, six were chosen for discussion at the press briefing with the changes depicted in time series or pairs of Landsat images.

  • Landsat Data: Community Standard for Data Calibration
    LANDSAT DATA: COMMUNITY STANDARD FOR DATA CALIBRATION A Report of the National Geospatial Advisory Committee Landsat Advisory Group October 2020 Landsat Data: Community Standard for Data Calibration October 2020 LANDSAT DATA: COMMUNITY STANDARD FOR DATA CALIBRATION Executive Summary Landsat has become a widely recognized “gold” reference for Earth observation satellites. Landsat’s extensive historical record of highly calibrated data is a public good and exploited by other satellite operators to improve their data and products, and is becoming an open standard. However, the significance, value, and use case description of highly calibrated satellite data are typically not presented in a way that is understandable to general audiences. This paper aims to better communicate the fundamental importance of Landsat in making Earth observation data more accessible and interoperable for global users. The U.S. Geological Survey (USGS), in early 2020, requested the Landsat Advisory Group (LAG), subcommittee of the National Geospatial Advisory Committee (NGAC) to prepare this paper for a general audience, clearly capturing the essence of Landsat’s “gold” standard standing. Terminology, descriptions, and specific examples are presented at a layperson’s level. Concepts emphasize radiometric, geometric, spectral, and cross-sensor calibration, without complex algorithms. Referenced applications highlight change detection, time-series analysis, crop type mapping and data fusion/harmonization/integration. Introduction The National Land Imaging Program leadership from the U.S. Geological Survey (USGS) requested that the Landsat Advisory Group (LAG), a subcommittee of the National Geospatial Advisory Committee (NGAC), prepare a paper that accurately and coherently describes how Landsat data have become widely recognized as a radiometric and geometric calibration standard or “good-as-gold” reference for other multi-spectral satellite data.

  • Improving the Usability of Nighttime Imagery from Low Light Sensors
    Improving the Usability of Nighttime Imagery from Low Light Sensors Thomas F. Lee F. Joseph Turk Jeffrey D. Hawkins Cristian Mitrescu Naval Research Laboratory, Monterey California (USA) Steven D. Miller Cooperative Institute for Research in the Atmosphere Fort Collins Colorado (USA) Mike Haas Aerospace Corporation Silver Spring Maryland (USA) 1. Abstract This article presents the nighttime visible sensor on the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument to be flown aboard the upcoming NPOESS and NPP polar-orbiting satellites. First, we will introduce the sensor and explain how it improves on a similar sensor, the Operational Linescan System (OLS) flown on the Defense Meteorological Satellite Program (DMSP) series. A brief summary of the new instrument will be given, followed by a few example products from the OLS. The paper will close with a discussion of how the crossing time of the satellite affects the number of scenes that will have lunar illumination. 2. Introduction Low light imagery from the Operational Linescan System (OLS) aboard the Defense Meteorological Satellite Program (DMSP) satellites (Johnson et al. 1994) has prompted a number of important applications never foreseen by the United States Air Force which originally designed and launched the sensor in the early 1970’s. The unforeseen applications include composites of worldwide city lights at night; detection of fires; imaging of the aurora; monitoring of fishing boats; imaging of snow fields; detection of bioluminescence (Miller et al. 2005); and the detection of power outages. However, the sensor is still underutilized for the application for which it was originally designed, the imaging of clouds using moonlight.

These species, Black-throated Green Warbler, Nashville Warbler, and Ovenbird, were known to be associated with forest understory features during breeding. We examined the influences of varying two spatially explicit classification parameters on prediction accuracy: 1) the window size used to average spectral values in signature creation and 2) the threshold distance required for bird detections to be counted as present. Two accuracy measurements, proportion correctly classified (PCC) and Kappa, of maps predicting species’ occurrences were calculated with ground data not used during classification. Maps were validated for all three species with Kappa values >0.3 and PCC >0.6. However, PCC provided little information other than a summary of sample plot frequencies used to classify species’ presence and absence.
