This research study showed the potential of block bundle adjustment with nadir viewing sensor images, such as Landsat 7 ETM . The method is based on the 3D analytical geometric model developed for multisensor images at the Canada Centre for Remote Sensing, Natural Resources Canada. Different block sizes and configurations were tested and compared using an image bundle adjustment. The different ...

NASA and the US Geological Survey (USGS) are seeking to generate a map of the entire globe using Landsat 5 Thematic Mapper (TM) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+) sensor data from the “mid-decadal” period of 2004 through 2006. The global map is comprised of thousands of scene locations and, for each location, tens of different images of varying quality to chose from. Furthermore...

In this study, a comparative analysis of capabilities of three sensors for mapping forest crown closure (CC) and leaf area index (LAI) was conducted. The three sensors are Hyperspectral Imager (Hyperion) and Advanced Land Imager (ALI) onboard EO-1 satellite and Landsat-7 Enhanced Thematic Mapper Plus (ETM+). A total of 38 mixed coniferous forest CC and 38 LAI measurements were collected at Blod...

In Australia, remotely sensed Landsat data is routinely used for mapping and monitoring the change in extent of woody perennial vegetation. Time-series remotely sensed satellite imagery and ground information is used to form multi-temporal classifications of presence/absence of woody cover, typically for state-based management and reporting of clearing. More recently, there has been increased i...

This study concerned the assessment of changes in coastline Kavvayi beach and its nine islands a tropical coastal wetland using remote sensing (RS) data geographic information systems (GIS), as this sedimentary environment is still poorly characterized. The satellite used were from LANDSAT images (30 m spatial resolution) (MSS—volume 5, TM, ETM, ETM+ volume 6) for period last 25 years (1990 to ...

Quantifying sugarcane production is critical for a wide range of applications, including crop management and decision making processes such as harvesting, storage, and forward selling. This study explored a novel model for predicting sugarcane yield in Bundaberg region from time series Landsat data. From the freely available Landsat archive, 98 cloud free (<40%) Landsat Thematic Mapper (TM) and...
