The statements, opinions and data contained in the journal, © 1996-2021 MDPI (Basel, Switzerland) unless otherwise stated. The reason for this was to account for random errors that are inherent in the MCD12Q1-1 dataset, as well as account for oversampling within land classes from the weighted sampling method. They are obtained daily from the National Snow and Ice Data Center. For our validation process, we obtained Satellite Pour l’Observation de la Terre (SPOT-5) imagery for Singapore (, The initial step to an accuracy assessment is to decide the sampling strategy for the validation points. All sampling techniques contain some advantages and disadvantages. The DISCover map uses the IGBP classification scheme, while the UMd map employs a modified IGBP scheme minus the classes of permanent wetlands, cropland/natural vegetation mosaic and ice and snow. The user study and the accuracy assessment were carried out independent to one another, yet they complement each other by providing a comprehensive overview of the MCD12Q1-1, in terms of the land class information it contains and the locational accuracy of the pixels. The IGBP land cover classification scheme was developed during a series of meetings of the IGBP Land Cover Working Group held through 1995. Description. The land cover in GLDAS2/Noah is based on a 30 arc second MODIS vegetation data that uses modified IGBP classification scheme (see details). Such changes also determine, in part, the vulnerability of places and people to climatic . Land cover data is available from two global data products and one regional study: IGBP (International Geosphere-Biosphere program) presents a global classification of 1 km AVHRR (Advanced Very High Resolution Radiometer) data collected between April 1992 and March 1993 with 17 classes in the study area. The project was carried out as an International Geosphere-Biosphere Programme, Data and Information Systems (IGBP-DIS) initiative. Other, finer resolution gridded surface data are available. For example, a Kappa index of 0.45 indicates that overall agreement (from Equation (1)) is 45% better than the agreement due to chance. "The Climate Data Guide: CERES: IGBP Land Classification." Validation is carried out initially for all 17 IGBP land cover classes of the MCD12Q1-1 product, using the weighted stratified sampling. Feature Papers represent the most advanced research with significant potential for high impact in the field. This is mainly due to the low spatial resolution of the dataset, as well as the logic of the definitions created. IGBP, 1992, Improved Global Data for Land Applications, edited by J. R. G. Townshend. Furthermore, it is confirmed that the accuracy is 15%-20% higher than that of MODIS land cover product for the target classification area. 12, International Geosphere–Biosphere Programme, Stockholm, Sweden.

The land use types were first transformed into the land cover types. This type of The MODIS Terra+Aqua Combined Land Cover product incorporates five different land cover classification schemes, derived through a supervised decision-tree classification method. Owing to the highly urbanized landscape of Singapore, we commenced with two broad categories, namely “Urban” and “Non-Urban”. They were affiliated to the National University of Singapore (NUS), Urban Redevelopment Authority (URA), National Parks (NP), and the Centre for Remote Imaging Sensing and Processing, Singapore.

Through the formulation of an error matrix, we evaluate the following statistics for the accuracy of the IGBP classification of Singapore: Overall Accuracy: (No. In images containing a single land cover type, users were able to discern the cover type well. We analyse and discuss the descriptive statistics derived through our accuracy assessments in the following sections. The error matrix using the weighted stratified sampling scheme is detailed below (, In order to pre-correct our validation process, we repeated an accuracy assessment for the MCD12Q1-1, ignoring smaller redundant land classes. DISCover is a 17 class land cover dataset based on the science requirements of IGBP elements. Using this sampling strategy (. The user study explicitly focuses on the ambiguity of the IGBP land class definitions for different land classes contained in the MCD12Q1-1. An official website of the United States government. 1.

Thus, it was imperative to include users and officials who work with different types of land cover data to obtain more information. A set of three estimates of land-cover types and annual transformations of land use are provided on a global 0.5°x0.5° grid at annual timesteps. We further divide “Urban” into residential, Central Business District (CBD), and defence areas (e.g., military zones). It is known to work well for vast forested areas such as the Brazilian Amazon [. This outputs the probability of the actual agreement calculated being better than the agreement expected due to random chance. To compare our results with the International Geosphere-Biosphere Programme (IGBP) DISCover land cover dataset, we aggregated our land cover classes according to the IGBP classification system. A set of three estimates of land-cover types and annual transformations of land use are provided on a global 0.5°x0.5° grid at annual timesteps. In order to ethically carry out the user study and interviews in Singapore we were required to obtain clearance from the National University of Singapore Institutional Review Board (NUS-IRB).

The MCD12Q1 Version 6 data product is derived using supervised classifications of MODIS Terra and Aqua reflectance data. In the newly produced nighttime lights data, each cell represented the average nighttime light value of four cells, while each cell in the new land cover data represented the number of cells out of 100 which were categorized in the original IGBP data as urban or built-up land.
