COMPARING BROAD-BAND AND RED EDGE-BASED SPECTRAL VEGETATION INDICES TO ESTIMATE NITROGEN CONCENTRATION OF CROPS USING CASI DATA
LNC SVIs NDVI broad-band red edge-based CASI
2016/11/23
In recent decades, many spectral vegetation indices (SVIs) have been proposed to estimate the leaf nitrogen concentration (LNC) of crops. However, most of these indices were based on the field hypersp...
DETECTION OF SLOPE MOVEMENT BY COMPARING POINT CLOUDS CREATED BY SFM SOFTWARE
Structure from Motion ICP point cloud PCA Slope Monitoring
2016/11/11
This paper proposes movement detection method between point clouds created by SFM software, without setting any onsite georeferenced points. SfM software, like Smart3DCaputure, PhotoScan, and Pix4D, a...
VOLUME COMPUTATION OF A STOCKPILE–A STUDY CASE COMPARING GPS AND UAV MEASUREMENTS IN AN OPEN PIT QUARRY
UAV photogrammetry surveying of stockpiles volumetric computation GNSS technologies
2016/7/5
The following paper aims to test and evaluate the accuracy of UAV data for volumetric measurements to the conventional GNSS techniques. For this purpose, an appropriate open pit quarry has been chosen...
COMPARING AND SYNTHESIZING DIFFERENT GLOBAL AGRICULTURAL LAND DATASETS FOR CROP ALLOCATION MODELING
Cultivated land Land cover Remote sensing crop Food security
2016/1/3
Cultivated land has been feeding the world for thousands of years. Only in the last few decades, remote sensing is used to assess and monitor the extent and status of cultivated land. One of the great...

This paper describes a simple comparison of the distributions of land cover features identified from volunteered data contributed by different social groups – in this case comparing two groups of Geo-...
THE ENMAP CONTEST:DEVELOPING AND COMPARING CLASSIFICATION APPROACHES FOR THE ENVIRONMENTAL MAPPING AND ANALYSIS PROGRAMME–DATASET AND FIRST RESULTS
Hyperspectral Imaging EnMAP Classification Benchmark Datasets Evaluation Methodology
2015/9/21
The Environmental Mapping and Analysis Programme EnMAP is a hyperspectral satellite mission, supposed to be launched into space in the near future. EnMAP is designed to be revolutionary in terms of sp...
COMPARING THREE CANOPY REFLECTANCE MODELS WITH HYPERSPECTRAL MULTI-ANGULAR SATELLITE DATA
Canopy reflectance models forward modelling radiative transfer
2015/9/8
Studies that compare modelled reflectances with satellite-measured reflectances for different wavelengths and view angles are still
rare. We compared model outputs from three different canopy reflect...
COMPARING FREQUENCY-BASED MEASURES OF SPECTRAL AND MORHPOLOGICAL DIVERSITY WITH SOCIODEMOGRAPHIC CHARACTERISTICS IN AN URBAN AREA
frequency-based contextual classification urban morphometry housing crime lidar
2015/8/3
Remotely-sensed imagery has a demonstrated connection to urban demographic variables. In a previous study, frequency-based contextual counts of cover type classes have been related to census housing v...

FRAMEWORK FOR COMPARING SEGMENTATION ALGORITHMS
Segmentation Algorithms Mapping Point Clouds
2015/5/21
The notion of a ‘Best’ segmentation does not exist. A segmentation algorithm is chosen based on the features it yields, the properties of the segments (point sets) it generates, and the complexity of ...
