High resolution shrub cover raster maps of the Jornada Basin LTER, including JER and CDRRC (2011)
This data package contains two raster shrub cover maps of the Jornada Experimental Range (JER) and Chihuahuan Desert Rangeland Research Center (CDRRC) in southern New Mexico, USA. The maps are derived from 1m resolution National Agriculture Imagery Program (NAIP) aerial photos acquired in 2011. A one-meter resolution raster file lists cover as non-shrub or non-shrub. A hectare resolution raster file contains fractional shrub cover values (0-1) calculated from the one-meter raster.
Fig. 1. NASDA JERS-1 in Ecology and life history of an Amazon floodplain cichlid: the discus fish Symphysodon (Perciformes: Cichlidae)
Fig. 1. NASDA JERS-1 radar image of the Tefé region, Brazil: (a) high water (May 1995); (b) low water (September 1995). Flooded forests appear white, illustrating the maximum extent of the seasonal flooding. The area between the dotted lines is whitewater floodplain. R. Solimões is the local name for the Amazon River. Discus occur in the following habitats: 1, blackwater flooded forest (igapó), 2, blackwater lakes, 3, whitewater flooded forest, 4, whitewater floodplain lakes. Study are marked A (Uxi Bay) and B (lago Urini). Inset (c) shows Uxi Bay from Landsat TM-5 image, 1998. Here, the white dot represents the locality of a large discus colony and the line X-Y refer to the cross-sectional schematic (d). In (d) the dotted horizontal line represents the water level at the beginning of 1998 samples. The 4 m water-level (see also Fig. 2) marks the lower levels of shore scrub growing on beaches and sand bars. Shore scrub is dominated by Coccoloba ovata Benth. and Symmeria paniculata Benth. (Polygonaceae).
JERS-1 Synthetic Aperture Radar, 100-m Mosaics, South America: 1995-1996, R1
This data set provides ~100-m resolution image mosaics of South America acquired during the low flood season between September and December 1995 and during the high flood season between May and July of 1996. The images cover the same areas during both seasons and were obtained from the Japanese Earth Resources Satellite 1 (JERS-1) Synthetic Aperture Radar (SAR) of the National Space Development Agency of Japan (NASDA). The data were mosaicked into 34 tiles for each season, each consisting of about 50 JERS-1 scenes. This data set constitutes the first-ever high-resolution and single season coverage of the entire Amazon River Basin, made possible by the cloud penetrating properties of the radar sensor. The images are from the original JERS-1 SAR Global Rain Forest Mapping Project. This data set contains 66 files in GeoTIFF (.tiff) format. There are 32 files for the low flood season and 34 files for the high flood season.
LBA-ECO LC-15 JERS-1 Synthetic Aperture Radar, 1- km Mosaic, Amazon Basin: 1995-1996
This data set contains two image mosaics of L-band radar backscatter and two image mosaics of first order texture. The two backscatter images are mosaics of L-band Radar Backscatter at Horizontal-Horizontal (HH) Polarization created from 1,500 images collected by the Japanese Earth Resources Satellite-1 (JERS-1) Synthetic Aperture Radar (SAR) over the Amazon River Basin as part of the Global Rainforest Mapping Project (GRMP). These backscatter image mosaics were developed using data collected over 62 days from August to November of 1995 for the peak of the dry season and for 62 days from May to June of 1996 during the peak of the wet season. The two image mosaics are at 3 arc-sec resolution. Data provided under this project are resampled images at 30 arc-sec resolution (or about 1 km resolution). For each radar backscatter image, first order texture statistical information was derived and is distributed along with the image mosaic.This data set contains four images each in both geotiff and ENVI formats, provided in eight zip files. The four files in ENVI file format contain “_envi” in their file name and when extrapolated contain an envi image (*_envi.dat) and an envi image header file (_envi.hdr). The four files in geotiff format contain “_geotiff” in their file name and when extrapolated contain *.tif and *.tfw file pairs. See Section 2 for more information about the characteristics of these data files.
