The Verification of Land Cover Datasets with the Geo-Tagged Natural Scene Images

چکیده
Land cover is important for global change studies, and its accuracy reliability are usually verified by field sampling, which costs a lot. A method was proposed the verification of land datasets with geo-tagged natural scene images using convolutional neural network. The nature were firstly collected from Use Cover Area frame Survey (LUCAS) crowdsourcing platform Flickr, then classified according to Classification System. Nature Scene Image (NSIC) model based on GoogLeNet Inception network recognition constructed. Finally, in UK, as area, European Space Agency Climate Change Initiative (ESA CCI-LC) Global land-cover product fine classification system (GLC-FCS) NSIC-Inception image set. results showed that overall LUCAS very close product, 94.41% CCI LC 92.89% GLC-FCS, demonstrating feasibility NSIC model. In addition, VGG16 ResNet50 compared Inception. differences between Flickr discussed regarding image’s quantity, spatial distribution, representativeness, so on. uncertainties arising resolution different explored GCL-FCS. application has great potential support improve efficiency verification.

Investigating the Feasibility of Geo-Tagged Photographs as Sources of Land Cover Input Data
Geo-tagged photographs are used increasingly as a source of Volunteered Geographic Information (VGI), which could potentially be used for land use and land cover applications. The purpose of this paper is to analyze the feasibility of using this source of spatial information for three use cases related to land cover: Calibration, validation and verification. We first provide an inventory of the...
متن کاملActive Collection of Land Cover Sample Data from Geo-Tagged Web Texts
Sample data plays an important role in land cover (LC) map validation. Traditionally, they are collected through field survey or image interpretation, either of which is costly, labor-intensive and time-consuming. In recent years, massive geo-tagged texts are emerging on the web and they contain valuable information for LC map validation. However, this kind of special textual data has seldom be...

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...

When dealing with networked information spaces, there are two challenges a data navigation system must address: first, it needs to provide the user with a quick high-level overview of the nature and structure of the data. Second, it must offer mechanisms to easily drill down and navigate to specific detail information. In this demonstration, we present the Pelagios Graph Explorer, a prototype v...
متن کاملdeterminant of the hankel matrix with binomial entries
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
