While these datasets provide a good medium-scale land cover dataset, there are limitations to the NLCD's accuracy and use in finer-scale applications. Under the NEXTMap(R) USA program, Intermap TechnologiesTM is assembling a nationwide dataset of high-resolution 1.25-...
So, there you are – the first time you have used part of the NLCD dataset. Easy, wasn’t it? If all you are trying to achieve is a quick, high altitude overview render, then this is the most you would have to do to gain acceptable results. Once familiar with the process it ...
The Landsat Gross Primary Production (GPP) CONUS dataset estimates GPP using Landsat Surface Reflectance for CONUS. GPP is the amount of carbon captured by plants in an ecosystem and is an essential component in the calculations of Net Primary Production (NPP). GPP is calculated using … ...

To address accuracy concerns of the National Land Cover Dataset (), this case study compares impervious surface from the to a Detailed Land Cover Dataset () for the Town of Blacksburg, Virginia over two time periods (2005/2006 and 2011) at spatial aggregation scales (30 m and 90 m) and ...
We accepted the Census as the most accurate information available on cropland acreages; however, errors are known to exist in this dataset resulting from various issues, such as incompleteness of the mailing list and non-response of participants. Because these adjustments are applied at the state...
800 m daily gridded dataset (PRISM) is used as the climate input for the PRMS. Model parameters are obtained from various sources (e.g., NLCD 2011... Y Yoon,M. Conklin,R. Bales,... - AGU Fall Meeting Abstracts 被引量: 0发表: 2016年研究...
1.For that,four global land cover products were firstly compared with the national land cover dataset 2000(NLCD-2000)at provincial,regional and national scales to evaluate the accuracies of estimation of aggregated cropland area in China.该研究以中国耕地类别为研究对象,选择2000年中国土地利用数据(NL...
Additionally, we used the reference dataset collected for assessment of the NLCD2011 database to assess the 2001 and 2006 land cover components of the NLCD2016 database. OA for the 2001 and 2006 land cover components was 1% - 5% lower than OA for the 2011 and 2016 land cover components ...
For water and ice/snow areas, another component named AKUP11-WIS was developed for initial land cover change detection, removal of the terrain shadow effects, and exclusion of ephemeral snow changes using a 3-year MODIS snow extent dataset from 2010 to 2012. The overall approach was tested ...
