A hybrid methodology for detecting cartographically significant features using Landsat TM imagery by Robert S Rand( Book )

4 editions published in 1991 in English and held by 96 WorldCat member libraries worldwide

A general Change Detection (CD) methodology is investigated that involves a hybrid mix of image processing, spectral transformation, and statistical pattern recognition techniques. The Hybrid Methodology attempts to combine various forms of supporting and conflicting evidence for change into a resulting change map. The approach involves differencing registered multiband scene pairs that have undergone a spectral transformation, generating threshold masks, and applying a classifier to the masked multiband scene pairs
Contour-to-grid interpolation with nonlinear finite elements : a feasibility study by Betty A Mandel( Book )

4 editions published in 1987 in English and held by 95 WorldCat member libraries worldwide

This report concludes the second phase of a three-phase collaborative effort between the U.S. Army Engineer Topographic Laboratories and the National Bureau of Standards. The main objective of this effort is to develop and implement a contour-to-grid algorithm, that is, an algorithm capable of converting digitized contour data into Digital Terrain Elevation Data (DTED). The approach is to create a synthetic terrain surface based on digitized contour information and then to calculate any grid from that surface. Five tasks are to be performed: 1) Edit a digitized contour data set (input); 2) Thin (reduce, sample) the input data; 3) Triangulate the selected points; 4) Generate a smooth synthetic surface; and 5) Generate the desired grid. The first phase, which was completed in December 1985, addressed the first three tasks. The second phase, to which this report refers, elaborates on the previous results and includes work in all five areas. The effort demonstrates the feasibility of performing such tasks for large data sets, such as a Digital Graphic Recorder data tape of roughly 500,000 points

Multispectral image maps from Landsat thematic mapper data by Robert S Rand( Book )

3 editions published in 1991 in English and held by 91 WorldCat member libraries worldwide

This report describes a capability to produce prototype 1:50,000 scale multispectral image maps using Landsat TM data. These image maps are in the standard UTM projection, contain imbedded 1,000 meter grid lines with labeled UTM coordinates, and can easily be used in conjunction with conventional military maps of the same scale. Annotation that gives the title of the standard DMA map of the area, the Landsat TM band combinations, as well as a bar scale and compass were also imbedded into the product. (Author)

Autocorrelation of control points on 11-band multispectral imagery by Robert S Rand( Book )

3 editions published in 1987 in English and held by 83 WorldCat member libraries worldwide

The use of multispectral imagery with other types of imagery requires that the combined set be accurately registered. This study investigates correlation properties between bands of an 11--channel multispectral scanner for 37 control points in support of interband registration that can later be extended to dissimilar image registration. The results show a high degree of correlation between channels 1 through 7, but a lower and unpredictable correlation for other combinations. In addition to providing information about interband registration, the results also have implications for multispectral segmentation algorithms. Keywords: Autocorrelation measures, Image registration, Multispectral imagery, Feature extraction, Image segmentation algorithms
Hyperspectral signatures (400 to 2500 nm) of vegetation, minerals, soils, rocks, and cultural features : laboratory and field measurements by Melvin B Satterwhite( Book )

3 editions published in 1990 in English and held by 83 WorldCat member libraries worldwide

The objective of this catalog was to document the visible near- infrared reflectance spectra (400-2500nm) of vegetation, soils, rocks, and man- made materials, and to provide information about their unique physical and chemical properties. Spectra were taken of representative samples of a particular plant species or soil type and selected conditions so that a specific feature could be evaluated. Seasonal differences in vegetation spectra were measured for tree, shrub, herbaceous, and grass species. Soils having different textures and moisture potentials were measured. These spectra summarize results of on going research in different environments, although many of the field spectra were taken in semiarid and arid environments

PDEF, a standard file format for data interchange by Michael M McDonnell( Book )

3 editions published in 1991 in English and held by 82 WorldCat member libraries worldwide

This report explains a new method of encoding data in a set of files that allows advantages over current formats and methods. A new format is necessary because all current widely-available file formats retain restrictions (such as fixed field lengths) that are no longer necessary with modern programming languages. In particular, the ability to be parsed by FORTRAN programs was formerly an important requirement. The limitations of FORTRAN lead to file formats that are clumsy and difficult to work with. The proposed format has a simple syntax and flexible semantics. The format is efficient both for computers and people. It is efficient for computers because it makes use of the powerful parsing tools available for the C programming language. It is efficient for people because data descriptions are in a human-readable form and the content of a data file can be understood without a user's manual. The bulk of this report is in appendixes which give illustrative examples. Examples are presented for raster, quadtree, and vector data formats since these formats are especially prevalent in spatial data systems, a specialty of the U.S. Army Engineer Topographic Laboratories. PDEF stands for Protean Data Exchange Format

Texture analysis and cartographic feature extraction by Robert S Rand( Book )

3 editions published in 1985 in English and held by 73 WorldCat member libraries worldwide

Investigations into using various image descriptors as well as developing interactive feature extraction software on the Digital Image Analysis Laboratory(DIAL) have culminated in a revised procedure to test statistical classification methods. An interactive experiment using this procedure was performed and showed that of the image descriptors tested, the most significant was a two component vector derived from an average and a standard deviation measure of gray shades. The texture measures failed to deliver any increase in performance for the classifier. In general, this report shows that statistical classification methods are insufficient by themselves to deliver the performance needed in a semi-automated cartographic feature extraction system. Originator-supplied keywords: Ad-Hoc image descriptor; Bayes classifier; Bhattachryya distance; Clustering; Digital Image Analysis Laboratory (DIAL); Feature extraction; Interactive processing; Laws texture measure; Principal components; Raster processing; Relaxation
Diurnal freeze-thaw frequencies in selected regions of the high latitudes by Ruth L Wexler( Book )

2 editions published in 1984 in English and held by 69 WorldCat member libraries worldwide

The purpose of this study is to provide information on the incidence of daily freezing conditions, i.e., frost days (min <or = O C), and freeze-thaw days (min <or = 0 C max> O C), per month or year throughout Alaska, Eastern Siberia, Iceland, and Greenland. Tables are provided of the above parameters. In addition, linear regression equations were developed for each area for deriving the above information from ordinary climatic data. Station models of percent days per month with freeze-thaw throughout the year are also given for a range of climates in the regions indicated as well as for several German stations representing a range of elevation. Another set of models shows that the percent freeze-thaw per month could be expressed as a function of mean monthly temperature. The constants for the latter (sine) function reflect the continentality of the station. The various models presented demonstrate the relationship between daily freezing conditions and the temperature regime. The results should improve understanding of periglacial activity and provide a means of predicting possible climatic effects on the construction of buildings roads, and airport runways
